Stanford CS248, Spring 2018
INTERACTIVE COMPUTER GRAPHICS
This course provides a comprehensive introduction to computer graphics, focusing on fundamental concepts and techniques, as well as their crosscutting relationship to multiple problem domains in interactive graphics (such as rendering, animation, geometry, image processing). Topics include: 2D and 3D drawing, sampling, interpolation, rasterization, image compositing, the GPU graphics pipeline (and parallel rendering), geometric transformations, curves and surfaces, geometric data structures, subdivision, meshing, spatial hierarchies, image processing, compression, time integration, physicallybased animation, and inverse kinematics.
