Realtime Graphics on GPU (NPGR019)

Code/hours: NPGR019, 2/1 C+Ex (summer)
Schedule: Mon 16:00 S1 (Malá Strana)
Lecturer: ??
Pre-requisites: basic programming course, elementar knowledge of C++, basic calculus and linear algebra, Introduction to Computer Graphics (NPGR003)

This course extends the Introduction to Computer graphics course and focuses on modern, hardware-supported realtime graphics. It covers mathematical fundamentals of realtime graphics, data structures, architecture of modern GPUs, basic and advanced methods, GPU programming, GPGPU.

Additional labs focus on practical aspects of the subject, especially GPU shader programming. Exercises are using C#/C++ programming and GLSL shader languages. See the Grcis repository, Ogl repository.

Syllabus

History and architecture of GPU - typical 3D graphics pipeline, fixed vs. programmable pipeline
mathematics - homogeneous coordinates, projections, quaternions, interpolation and approximation curves, spline functions
3D scene representations - face-based models, triangle meshes, vertex arrays, index arrays, scene hierarchies (scene graph), Level of Detail (LoD), skinning, billboards
algorithms - visibility (depth-buffer), transparency, clipping, shading, perspective-correct interpolation, fog, texture mapping, bump-mapping, environment-mapping
basic techniques - passing data from CPU to GPU, data types, textures, index-buffers, VBOs, strips/fans, double-buffering, accumulation buffer, stencil-buffer, multi-pass rendering
GPU programming - shaders - architecture and history, principles, vertex-, geometry- tesselation-, fragment- shaders
API for realtime graphics - OpenGL, GLSL language, shader samples
advanced techniques (if there is enough time) - vertex attributes, environment mapping, bump-mapping, use of accumulation and stencil buffers: motion blur, depth of field, shadow maps and volumetric shadows, skelatal animation, skinning..
