Jim Henson的个人简介

James Maury "Jim" Henson (September 24, 1936, Greenville, Mississippi – May 16, 1990, New York, New York), was one of the most widely known puppeteers in American television history.[1] He was the creator of The Muppets, Fraggle Rock, and the leading force behind their long run in the television series Sesame Street and The Muppet Show and films such as The Muppet Movie (1979) and The Dark Crystal and Labyrinth (1986). He was also an Oscar-nominated film director, Emmy Award-winning television producer, and the founder of The Jim Henson Company, the Jim Henson Foundation, and Jim Henson's Creature Shop.

Henson's sudden death on May 16, 1990, of Streptococcal Toxic Shock Syndrome (STSS, not to be confused with TSS), resulted in an outpouring of public and professional affection. There have since been numerous tributes and dedications in his memory. Henson’s companies, which are now run by his children, continue to produce films and television shows.

On September 26, 1992, Henson was posthumously awarded the Courage of Conscience Award for being a "Humanitarian, muppeteer, producer and director of films for children that encourage tolerance, interracial values, equality and fair play."[2]

Early life

Jim Henson was the younger of two boys. His parents were Paul Henson, agronomist for the U.S. Department of Agriculture, and Elizabeth Marcella Henson.[3] After spending his early childhood in Leland, Mississippi, he moved with his family to Hyattsville, Maryland, near Washington, DC, in the late 1940s. Henson was raised as a Christian Scientist;[4] he later remembered the arrival of the family's first television as "the biggest event of his adolescence,"[5] being heavily influenced by radio ventriloquist Edgar Bergen and the early television puppets of Burr Tillstrom (on Kukla, Fran and Ollie) and Bil and Cora Baird.[5]

In 1954, while attending Northwestern High School, he began working for WTOP-TV creating puppets for a Saturday morning children's show. After graduating from high school, Henson enrolled at University of Maryland, College Park as a studio arts major, thinking he might become a commercial artist.[6] A puppetry class offered in the applied arts department introduced him to the craft and textiles courses in the College of Home Economics, and he graduated with a B.S. in home economics in 1960.[citation needed] As a freshman, he was asked to create Sam and Friends, a five-minute puppet show for WRC-TV. The characters on Sam and Friends were already recognizable Muppets, and the show included a primitive version of what would become Henson's most famous character, Kermit the Frog.[7]

In the show, he began experimenting with techniques that would change the way puppetry was used on television, including using the frame defined by the camera shot to allow the puppeteer to work from off-camera. Henson believed that television puppets needed to have "life and sensitivity,"[8] and so, at a time when many puppets were made out of carved wood, Henson began making characters from flexible, fabric-covered foam rubber, allowing them to express a wider array of emotions.[3] In contrast to a marionette, whose arms are manipulated by strings, Henson used rods to move his muppets' arms, allowing for greater control of expression. Additionally, Henson wanted the muppet characters to "speak" more creatively than previous puppets, which had seemed to have random mouth movements; he used, and directed his muppeteers to use, precision mouth movements to match the dialogue.

When Henson began work on Sam and Friends, he asked fellow University of Maryland freshman, Jane Nebel, to assist him. The show was a financial success, but after graduating from college, Jim began to have doubts about going into a career as a puppeteer. He wandered off to Europe for several months, where he was inspired by European puppeteers who looked on their work as a form of art.[9] Henson returned to the United States and he and Jane began dating. They were married in 1959 and had five children: Lisa (b. 1960), Cheryl (b. 1962), Brian (b. 1963), John (b. 1965) and Heather (b. 1970).

Struggles and projects in the 1960s

Despite the success of Sam and Friends, which ran for six years, Henson spent much of the next two decades working in commercials, talk shows, and children's projects before being able to realize his dream of the Muppets as "entertainment for everybody".[5] The popularity of his work on Sam and Friends in the late fifties led to a series of guest appearances on network talk and variety shows. Henson himself appeared as a guest on many shows, including The Ed Sullivan Show. This greatly increased exposure led to hundreds of commercial appearances by Henson characters through the sixties.

Among the most popular of Henson's commercials was a series for the local Wilkins Coffee company in Washington, D.C.,[10] in which his Muppets were able to get away with a greater level of slapstick violence than might otherwise have been acceptable with human actors. In the first Wilkins ad, a Muppet named Wilkins is poised behind a cannon seen in profile. Another Muppet named Wontkins is in front of its barrel. Wilkins asks, "What do you think of Wilkins Coffee?" to which Wontkins responds gruffly, "Never tasted it!" Wilkins fires the cannon and blows Wontkins away, then turns the cannon directly toward the viewer and ends the ad with, "Now, what do you think of Wilkins?" Henson later explained, "Till then, [advertising] agencies believed that the hard sell was the only way to get their message over on television. We took a very different approach. We tried to sell things by making people laugh."[11] The first seven-second commercial for Wilkins was an immediate hit and was syndicated and reshot by Henson for local coffee companies across the United States;[10] he ultimately produced more than 300 coffee ads.[11] The same setup was used to pitch Kraml Milk in the Chicago, Il., area.

In 1963, Henson and his wife moved to New York City, where the newly formed Muppets, Inc. would reside for some time. When Jane quit muppeteering to raise their children, Henson hired writer Jerry Juhl in 1961 and puppeteer Frank Oz in 1963 to replace her;[12] Henson later credited both with developing much of the humor and character of his Muppets.[13] Henson and Oz, particularly, developed a close friendship and a performing partnership that lasted 27 years; their teamwork is particularly evident in their portrayals of the characters of Bert and Ernie and Kermit and Fozzie Bear.[14]

Henson's sixties talk show appearances culminated when he devised Rowlf, a piano-playing anthropomorphic dog. Rowlf became the first Muppet to make regular appearances on a network show, The Jimmy Dean Show. From 1964 to 1968, Henson began exploring film-making and produced a series of experimental films. His nine-minute Time Piece was nominated by the Academy of Motion Picture Arts and Sciences for an Oscar for Short Film in 1966. Jim Henson also produced another experimental film, The NBC-TV movie The Cube, in 1969.

Though he was still engaged in creating children's programming, such as the successful eighties shows Fraggle Rock and the animated Muppet Babies, Henson continued to explore darker, mature themes with the folk tale and mythology oriented show The Storyteller (1988). The Storyteller won an Emmy for Outstanding Children's Program but was cancelled after nine episodes. The next year, Henson returned to television with The Jim Henson Hour, which mixed lighthearted Muppet fare with riskier material. The show was critically well-received and won Henson another Emmy for Outstanding Directing in a Variety or Music Program, but was cancelled after 13 episodes due to low ratings. Henson blamed its failure on NBC's constant rescheduling.[24]

Later work

In late 1989, Henson entered into negotiations to sell his company to The Walt Disney Company for almost $150 million, hoping that, with Disney handling business matters he would "be able to spend a lot more of my time on the creative side of things."[24] By 1990, he had completed production on a television special, The Muppets at Walt Disney World, and a Disney World (Later Disney's California Adventure as well) attraction, Jim Henson's Muppet*Vision 3D, and was developing film ideas and a television series titled Muppet High.[4]

Natural History Project and Dinosaurs

In the late 1980s, Henson worked with illustrator/designer William Stout on a feature film starring animatronic dinosaurs with the working title of The Natural History Project. In 1991, news stories written around the premiere of the Jim Henson Company-produced Dinosaurs sitcom highlighted the shows connection to Henson, who had died the year before. "Jim Henson dreamed up the show's basic concept about three years ago," said a New York Times article in April 1991. "'He wanted it to be a sitcom with a pretty standard structure, with the biggest differences being that it's a family of dinosaurs and their society has this strange toxic life style,' said [his son] Brian Henson. But until The Simpsons took off, said Alex Rockwell, a vice president of the Henson organization, 'people thought it was a crazy idea.'"[25] A New Yorker article said that Henson continued to work on a dinosaur project (presumably the Dinosaurs concept) until the "last months of his life."[26]

[edit] Death

While busy with these later projects, Henson began to experience flu-like symptoms.[4]

On May 4, 1990, Henson made an appearance on The Arsenio Hall Show. At the time, he mentioned to his publicist that he was tired and had a sore throat, but felt that it would go away.[citation needed]

On May 12, 1990, Henson traveled to Ahoskie, North Carolina, with his daughter Cheryl to visit his father and stepmother. The next day, feeling tired and sick, he consulted a physician in North Carolina, who could find no evidence of pneumonia by physical examination and prescribed no treatment except aspirin.[27] Henson returned to New York on an earlier flight and canceled a Muppet recording session scheduled for May 14.[citation needed]

Henson's wife Jane, from whom he was separated, came to visit and sat with him talking throughout the evening. By 2 a.m. on May 15, 1990 he was having trouble breathing and began coughing up blood. He suggested to Jane that he might be dying, but did not want to bother going to the hospital. She later told People Magazine that it was likely due to his desire not to be a bother to people.[4]

At 4 a.m., he finally agreed to go to New York Hospital, at which point his body was rapidly shutting down. By the time he was admitted at 4:58 a.m., he could no longer breathe on his own and had abscesses in his lungs. He was placed on a mechanical ventilator to help him breathe, but his condition deteriorated rapidly into septic shock despite aggressive treatment with multiple antibiotics. Only twenty hours later, on Wednesday May 16, 1990, at 1:21 a.m., Henson died from organ failure at the age of 53 at New York Hospital.

The cause of death was first reported as streptococcus pneumonia, a bacterial infection.[5] Bacterial pneumonia is usually caused by Streptococcus pneumoniae, an alpha-hemolytic species of Streptococcus. Henson, however, died of organ failure due to infection by Streptococcus pyogenes, a severe Group A streptococcal infection, that engulfed his body.[28] S. pyogenes is the bacterial species that causes scarlet fever, rheumatic fever and, in Henson's case, Toxic Shock Syndrome.

Two separate memorial services were held for Henson, one in New York City at the Cathedral of St. John the Divine and one in London, England, at St. Paul's Cathedral. As per Henson's wishes, no one in attendance wore black, and a Dixieland jazz band finished the service by performing "When The Saints Go Marching In". Harry Belafonte sang "Turn the World Around," a song he had debuted on The Muppet Show, as each member of the audience waved, with a puppeteer's rod, an individual, brightly-colored foam butterfly.[29] Later, Big Bird (performed by Carroll Spinney) walked out onto the stage and sang Kermit the Frog's signature song, "Bein' Green".[30]

In the final minutes of the two-and-a-half hour service, six of the core Muppet performers sang, in their characters' voices, a medley of Jim Henson's favorite songs, culminating in a performance of "Just One Person" that began with Richard Hunt singing alone, as Scooter. "As each verse progressed," Henson employee Chris Barry recalled, "each Muppeteer joined in with their own Muppets until the stage was filled with all the Muppet performers and their beloved characters."[30] The funeral was later described by LIFE as "an epic and almost unbearably moving event." The image of a growing number of performers singing "Just One Person" was recreated for the 1990 television special The Muppets Celebrate Jim Henson and inspired screenwriter Richard Curtis, who attended the London service, to write the growing-orchestra wedding scene of his 2003 film Love Actually.[31]

Jim was cremated at Ferncliff Cemetery. His ashes were scattered in Santa Fe, New Mexico, at his ranch.[32]

[edit] Business legacy

The Jim Henson Company and the Jim Henson Foundation continued after his death, producing new series and specials. Jim Henson's Creature Shop, founded by Henson, also continues to build creatures for a large number of other films and series (most recently the science fiction production Farscape, the film adaptation of The Hitchhiker's Guide to the Galaxy, and the movie MirrorMask) and is considered one of the most advanced and well respected creators of film creatures. His son Brian and daughter Lisa are currently the co-chairs and co-CEOs of the Company; his daughter Cheryl is the president of the Foundation. Steve Whitmire, a veteran member of the Muppet puppeteering crew, has assumed the roles of Kermit the Frog and Ernie, the most famous characters formerly played by Jim Henson.[33]

On February 17, 2004, it was announced that the Muppets (excluding the Sesame Street characters, which are separately owned by Sesame Workshop) and the Bear in the Big Blue House properties had been sold by Henson's heirs to The Walt Disney Company. The Jim Henson Company retains the Creature Shop, as well as the rest of its film and television library including Fraggle Rock, Farscape, The Dark Crystal, and Labyrinth.[34]

In February 2008, the Empire Film Group announced that it was planning to produce and distribute Henson, a film chronicling the life and achievements of Jim Henson. The film's screenplay was written by Robert D. Slane, and Empire plans to attract "a major director, such as Penny Marshall" and "notable star cast in key roles."[35]

Tributes

The Center for Puppetry Arts in Atlanta, Georgia, has acquired more than 700 puppets created by Henson and his studio, including some of the earliest Muppets. Many of these are displayed in the museum exhibit Jim Henson: Puppeteer. In September 2008, the Center for Puppetry Arts opened Jim Henson: Wonders From His Workshop, highlighting creations from Fraggle Rock, Labyrinth, and other later works.

Henson is honored both as himself and as Kermit the Frog on the Hollywood Walk of Fame. The only other person to receive this honor is Mel Blanc, the voice actor of Bugs Bunny.

The classes of 1994, 1998, and 1999 at the University of Maryland, College Park, Henson's alma mater, commissioned a life-size statue of Henson and Kermit the Frog, which was dedicated on September 24, 2003, Henson's 67th birthday. The statue cost $217,000, and is displayed outside Maryland's student union.[36] In 2006, Maryland introduced 50 statues of their school mascot, Testudo the Terrapin, with various designs chosen by different sponsoring groups. Among them was Kertle, a statue by Washington DC artist Elizabeth Baldwin designed to look like Kermit the Frog.

The theater at his alma mater, Northwestern High School, in Hyattsville, MD, is named in his honor.

Teenage Mutant Ninja Turtles II: The Secret of the Ooze and The Muppet Christmas Carol are both dedicated to him.

The television special The Muppets Celebrate Jim Henson allowed the Muppets themselves to pay tribute to Henson. The special featured interviews with Steven Spielberg and others.

A museum was built in memory of Henson in Leland, Mississippi. Official certificates from the Mississippi Legislature honoring Jim Henson and Muppets paraphernalia are on display.

Tom Smith's Henson tribute song, "A Boy and His Frog," won the Pegasus Award for Best Filk Song in 1991.

Stephen Lynch produced a song titled "Jim Henson's Dead," in which he pays homage to many of the characters from The Muppet Show and Sesame Street.

J. G. Thirlwell (under the alias Foetus In Excelsis Corruptus) performed a reworked version of Elton John's "Rocket Man" titled "Puppet Dude," with the lyrics altered to refer to Jim Henson. This can be found on the Male live album.

Apple Computer's "Think Different" advertising campaign featured Henson.

Oury Atlan, Thibaut Berland, and Damien Ferri wrote, directed, and animated a 3D tribute to Henson entitled "Over Time" which was shown as part of the 2005 Electronic Theater at SIGGRAPH.

Was featured in the Boyz II Men video, "It's So Hard to Say Goodbye to Yesterday"

Featured in The American Adventure in Epcot at the Walt Disney World Resort

Vintage footage of Henson was featured in an American Express credit card commercial in 2008.

Philip Roth often quotes Jim Henson in his Sabbath's Theater as the "great regret" for Mickey Sabbath.

面绘制有两种：1、基于断层轮廓线

先在不同切片上提取出感兴趣区域的轮廓线，然后，根据相邻切片的轮廓线构造出三角面片集。

这种方法弊端很明显：轮廓线之间的插值，轮廓线之间的对齐，同一个切片上的不同轮廓线。

Marching Cubes算法工作原理

Marching Cubes算法是三维数据场等值面生成的经典算法，是体素单元内等值面抽取技术的代表。

等值面是空间中所有具有某个相同值的点的集合。它可以表示为， ，c是常数。则称F(f)为体数据f中的等值面。

在MC算法中，假定原始数据是离散的三维空间规则数据场。用于医疗诊断的断层扫描(CT)及核磁共振成像(MRI) 等产生的图像均属于这一类型。MC算法的基本思想是逐个处理数据场中的体素，分类出与等值面相交的体素，采用插值计算出等值面与体弯陪素棱边的交点。根据体素中每一顶点与等值面的相对位置，将等值面与立方体边的交点按一定方式连接生成等值面，作为等值面在该立方体内的一个逼近表示。在计算出关于体数据场内等值面的有关参数后山常用的图形软件包或硬件提供的面绘制功能绘制出等值面。

图2.1 离散的三维空间规则数据场中的一个体素

2.1.1 MC算法的主要步骤

1． 确定包含等值面的体素

离散的三维空间规则数据场中的一个体素可以用图2.1表示。8个数据点分别位于该体素的8个角点上。MC算法的基本假设是:沿着体素的边其数据场呈局部连续线性变化，根据这个假设，可认为，如果两个相邻采样点一个为正点，一个为负点，则它们连成的边上一定存在且仅有一个等值点 (设等值面值为c)。如果得到了体素各条边上的等值点，就可以以这些点为顶点，用一系列的三角形拟合出该体素中的等值面。因此确定立方体体素中等值面的分布是该算法的基础。

首先对体素的8个顶点进行分类，以判断其顶点是位于等值面之外，还是位于等值面之内。再根据8个顶点的状态，确定等值面的剖分模式。顶点分类规则为:

1. 如体素顶点的数据值大于或等于等值面的值，则定义该顶点位于等值面之外， 记为正点，即“1“

2. 如体素顶点的数据值小于等值面的值，则定义该顶点位于等值面之内，记为负点， 即“0"

由于每个体素共有8个顶点，且每个顶点有正负两种状态，所以等值面可能以 =256种方式与一个体素相交。通过列举出这256种情况，就能创建一张表格，利用它可以查出任意体素中的等值面的三角面片表示。如果考虑互补对称性，将等值面的值和8个角点的函数值的大小关系颠倒过来，即将体素的顶点标记置反(0变为1, 1变为0)，这样做不会影响该体素的8个角点和等值面之间的拓扑结构，可将256种方式简化成128种。其次，再利用旋转对称性，可将这128种构型进一步简化成15种。图3.2给出了这15种基本构型[131其中黑点标记为“1”的角点。

图2.2 分布状态表

图2.3 体素角点分布不同情况

基于上面的分析，MC算法中用一个字节的空间构造了一个体素状态表，如图2.2所示，该状态表中的每一位可表示出该体元中的一个角点的0或1的状态。根游信据这一状态表，就可知道当前体素属于图2.3中哪一种情况，以及等值面将与哪一条边相交。

2.求等值面与体元边界的交点

在确定体素内三角剖分模式后，就要计算三角片顶点位置。神闹轮当三维离散数据场的密度较高时，即当体素很小时，可以假定函数值沿体素边界呈线性变化，这就是MC算法的基本假设。因此，根据这一基本假设，可以直接用线性插值计算等值面与体素边的交点。

对于当前被处理体素的某一条边，如果其两顶点 ， 的标记值不同，那么等值面一定与此边相交，且仅有一个交点。交点为 其中P代表等值点坐标, , 代表两个端点的坐标， ， 代表两个端点的灰度值，v代表域值。求出等值面与体素棱边的交点以后，就可以将这些交点连接成三角形或多边形，形成等值面的一部分。

3.等值面的法向量计算

为了利用图形硬件显示等值面图象，必须给出形成等值面的各三角面片的法向分量，选择适当的局部面光照模型进行光照计算，以生成真实感图形。

对于等值面上的每一点，其沿面的切线方向的梯度分量应该是零，因此，该点的梯度矢量的方向也就代表了等值面在该点的法向量，当梯度值非零。所幸的是等值面往往是由两种具有不同密度的物质的分解面，因此其上的每点的梯度矢量均不为零，即

Mc算法采用中心差分方法求采样点p〔m ,n, k ) 处的梯度矢量，公式如下:

Gx=〔g(i+1,j,k)-g(i-1,j,k)〕/2dx

Gy=〔g(i,j+1,k)-g(i,j-1,k)〕/2dy

Gz=〔g(i,j,k+1)-g(i,j,k-1)〕/2dz

其中D（i，j ,k）是切片k在像素（i，j）的密度， , ， 是立方体边的长度。对g进行归一化，得到(gx/｜g｜，gy/｜g｜，gz/｜g｜）作为（i,j,k)上的单位法向量。然后，对体素八个顶点上法向量进行线性插值就可得到位于体素棱边上的三角片的各个顶点上的法向量。设计算得到的某个三角片的三个顶点上的单位法向量分别为( , 和 )，这个三角片的几何重心为 ，则该三角片的法向量起始于 ，终止于 。代入Gourand光照模型公式，就可计算出小三角片表面的光强(灰度)。将其投影在某个特定的二维平面上进行显示，从而显示出物体富有光感的整个表面形态。其中我们在内存中保留四个切片来计算立方体中所有顶点梯度。

2.1.2 MC算法流程

1、将三维离散规则数据场分层读入内存;

2、扫描两层数据，逐个构造体素，每个体素中的8个角点取自相邻的两层;

3、将体素每个角点的函数值与给定的等值面值c做比较，根据比较结果，构造

该体素的状态表;

4、根据状态表，得出将与等值面有交点的边界体素;

5、通过线性插值方法计算出体素棱边与等值面的交点;

6、利用中心差分方法，求出体素各角点处的法向量，再通过线性插值方法，求出三角面片各顶点处的法向;

7,根据各三角面片上各顶点的坐标及法向量绘制等值面图像。
