A real-time procedural shading system for programmable graphics hardware

Kekoa Proudfoot, William R. Mark, Svetoslav Tzvetkov, Pat Hanrahan
2001 Proceedings of the 28th annual conference on Computer graphics and interactive techniques - SIGGRAPH '01  
Higher-level abstractions would both increase programmer productivity and make programs more portable.  ...  Real-time graphics hardware is becoming programmable, but this programmable hardware is complex and difficult to use given current APIs.  ...  The language itself is simpler and less ambitious than RenderMan.  ...

Procedural 3D texture synthesis using genetic programming

Adam Hewgill, Brian J Ross
2004 Computers & graphics  
In order to be practical for 3D model rendering, the language includes primitives that access surface information for the point being rendered, such as coordinates values, normal vectors, and surface gradients  ...  The texture generation language used here includes operators useful for texture creation, for example, mathematical operators, colour functions and noise functions.  ...  Ibrahim's Genshade system evolves Renderman shaders [10] . Highlevel Renderman shader expressions are denoted as dataflow graphs.  ...

An Introductory Computer Graphics Course in the Context of the European Space of Higher Education: A Curricular Approach [chapter]

Akemi Gálvez, Andrés Iglesias, Pedro Corcuera
2008 Lecture Notes in Computer Science  
In this context, the present paper focuses on the problem of teaching computer graphics, a discipline that is getting increasing importance in the realm of Computational Science.  ...  This process of reforms implies not only a re-evaluation of our way of teaching and learning but also a new curricular design in order to achieve the expected goals.  ...  Students find it difficult to solve logic problems in an axiomatic way, and are less skilled in deduction, mathematical intuition and scientific reasoning.  ...

Textures and radiosity

Reid Gershbein, Peter Schröder, Pat Hanrahan
1994 Proceedings of the 21st annual conference on Computer graphics and interactive techniques - SIGGRAPH '94  
The former does not capture important lighting effects due to textures, while the latter is too expensive computationally to be practical.  ...  This extension of the standard algorithm allows the use of textures to describe complex reflectance and emittance patterns over surfaces, increasing the realism and complexity of radiosity images.  ...  Many thanks also to Don Mitchell, Michael Cohen, and Steven Gortler for stimulating discussions and David Laur for production help.  ...
