Currently we do not include algorithms particular to business data processing, communications, operating systems or distributed algorithms, programming languages, ai, graphics, or numerical analysis: it is tough enough covering "general" algorithms and data structures. binary space partitioning (bsp) tree can be used for hidden surface removal. in order to hide invisible surfaces, all surfaces are sorted back to front or front to back order. traversal of bsp trees for back to front order of faces requires calculation for all bsp tree nodes, which can be made in

Ray tracing ray tracing is a method to produce realistic images; it determines visible sur-faces in an image at the pixel level (appel, 1968; kay & greenberg, 1979; whit- ted, 1980). unlike the z-buffer and bsp tree, ray tracing operates pixel-by-pixel rather than primitive-by-primitive. this tends to make ray tracing relatively slow for scenes with large objects in screen space. however, it spatial subdivision matthias teschner university of freiburg collision detection collision response university of freiburg - institute of computer science - computer graphics laboratory n space is divided up into cells n object primitives are placed into cells n object primitives within the same cell are checked for collision basic idea university of freiburg - institute of computer science
