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 ...
In computer graphics, free-form deformation (FFD) is a geometric technique used to model simple deformations of rigid objects. It is based on the idea of enclosing an object within a cube or another hull object, and transforming the object within the hull as the hull is deformed.
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.
The Blend4Web framework leverages Blender to edit 3D scenes. Content rendering relies on WebGL, Web Audio, WebVR, and other web standards, without the use of plug-ins. [2] It is dual-licensed. The framework is distributed under the free and open source GPLv3 and, a non-free license - with the source code being hosted on GitHub. [3]
Alembic is an interchangeable computer graphics file format developed by Sony Pictures Imageworks and Industrial Light & Magic. [3] [4] [5] It was announced at SIGGRAPH 2011, [1] and has been widely adopted across the industry by visual effects and animation professionals.
Standard Cornell box rendered with POV-Ray Cornell box with 3 balls to model how different materials reflect light.. The Cornell box is a test aimed at determining the accuracy of rendering software by comparing the rendered scene with an actual photograph of the same scene, [1] and has become a commonly used 3D test model.
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.
