5. What is Computer Graphics? More specifically, what is 3D graphics? We call this 2D graphics:

6. What is 3D? Is this 3D graphics?

7. Computer Graphics: 1960-1970 Wireframe graphics Project Sketchpad Display Processors Storage tube

8. Raster Graphics Allow us to go from lines and wireframes to filled polygons

9. Computer Graphics: 1980- 1990 Special purpose hardware –Silicon Graphics geometry engine VLSI implementation of graphics pipeline Industry-based standards –PHIGS; GKS…etc. (vs. OpenGL today) –RenderMan Networked graphics: X Window System Human-Computer Interface (HCI)

10. Computer Graphics: 1990- 2000 OpenGL API Completely computer-generated feature-length movies (Toy Story) are successful New hardware capabilities –Texture mapping –Blending –Accumulation, stencil buffer

11. Computer Graphics: 2000- Photorealism Graphics cards for PCs dominate market –Nvidia, ATI, 3DLabs Game boxes and game players determine direction of market Computer graphics routine in movie industry: Maya, Lightwave
