ACM SIGGRAPH is the international Association for Computing Machinery's Special Interest Group on Computer Graphics and Interactive Techniques based in New York. It was founded in 1969 by Andy van Dam (its direct predecessor, ACM SICGRAPH was founded two years earlier in 1967).
SIGGRAPH (Special Interest Group on Computer Graphics and Interactive Techniques) is an annual conference centered around computer graphics organized by ACM, starting in 1974 in Boulder, CO. The main conference is usually held in North America though is not limited in location possibilities; SIGGRAPH Asia, a second conference held annually, has ...
The technique was first described by Thomas W. Sederberg and Scott R. Parry in 1986, [1] and is based on an earlier technique by Alan Barr. [2] It was extended by Coquillart to a technique described as extended free-form deformation , which refines the hull object by introducing additional geometry or by using different hull objects such as ...
It was created by Cindy M. Goral, Kenneth E. Torrance, Donald P. Greenberg, and Bennett Battaile at the Cornell University Program of Computer Graphics for their paper Modeling the Interaction of Light Between Diffuse Surfaces published and presented at SIGGRAPH'84. [2] [3] A physical model of the box is created and photographed with a CCD camera.
Unveiled at the 1988 SIGGRAPH convention, it was the first live performance of a digital character. Mike was a sophisticated talking head driven by a specially built controller that allowed a single puppeteer to control many parameters of the character's face, including mouth, eyes, expression, and head position.
In 1978 Jim Blinn described how the normals of a surface could be perturbed to make geometrically flat faces have a detailed appearance. [2] The idea of taking geometric details from a high polygon model was introduced in "Fitting Smooth Surfaces to Dense Polygon Meshes" by Krishnamurthy and Levoy, Proc. SIGGRAPH 1996, [3] where this approach was used for creating displacement maps over nurbs.
The second version, glTF 2.0, was released in June 2017, and is a complete overhaul of the file format from version 1.0, with most tools adopting the 2.0 version. [ 4 ] [ 5 ] Based on a proposal by Fraunhofer [ 13 ] originally presented at SIGGRAPH 2016, Physically based rendering (PBR) was added, replacing WebGL shaders used in glTF 1.0.
