Basic Tests - Producing Polygon Surface
A few basic tests that must be performed before producing a polygon surface through any graphic package as:
1) All vertexes are listed as an endpoint for at least two edges,
2) All edges are part of at least one polygon,
3) All polygons are closed,
4) All polygons have at least one shared edge,
5) If the edge table comprises pointer to polygons, each edge referenced through a polygon pointer to polygon, all edges referenced through a polygon pointer has a reciprocal pointer back to polygon.
Geometric tables - Polygon Tables 1) Vertex table: Keep vertices' coordinates values in the object. 2) Edge table: Keep pointers back in to the vertex table for identif
Implement displacement mapping and bump mapping on a sphere. The displacement can be whatever your choice. The bump map can be whatever your choice as well.
