Real-time Computer Graphics Overview A guide to the contents of the course Introduction to Computer Graphics CSE 470/598 Arizona State University Dianne Hansford

CG Overview Geometry Processing Modeling Rasterization Display

CG Overview Geometry Processing Modeling Rasterization Display Generate vertices Primitives (vertex, line, triangle) Surfaces of revolution Bezier and B-spline curve & surface methods Subdivision curves and surfaces Etc …

CG Overview Geometry Processing Modeling Rasterization Display Determine which geometric objects appear and how they appear Camera model Normalization to canonical viewing volume Clipping Hidden surface removal (software) Illumination and shading Projection onto 2D window

CG Overview Geometry Processing Modeling Rasterization Display Convert normalized (floating point) primitives to (integer) pixels OGL fragments: pixels, color, z-depth, texture Z-buffer hidden surface removal

CG Overview Geometry Processing Modeling Rasterization Display Frame buffer to CRT conversion And adjust pixels for special results Anti-aliasing Fog More texturing

CG Overview Viewing Pipeline Geometry Processing Modeling Rasterization Display Determine which objects appear and how Convert floating point geometry to integer pixel Adjust pixels for special results Generate vertices Viewing Pipeline
