12.1 INTRODUCTION


ؕؓ

After a geometric model is constructed, it must be displayed (rendered).

Rendering is mainly limited by computer hardware, and the geometric model.

The main methods for doing computer graphics are,

- Wire Frame
- Wire frame with hidden line removal
- Polygon drawing (backface, and clipping)
- Shaded polygons
- Raytracing

As the scene becomes more complicated, the computing time becomes longer, but the picture becomes more realistic.

The basic history of research on geometric modeling can be summarized as,

- 2D computer drafting - Mid 60s
- 2.5 D - Late 60s
- 3D Wire Frame Systems - Early 70s
- 3D Surface Systems - Mid 70s
- 3D Primitive Solids - Early to Mid 70s
- 3D Arbitrary Solids - Mid to Late 70s
