Homework 4 Due: 3/16

Embossed surfaces.

Embossing a surface can generate apparent depth in an otherwise flat surface (http://en.wikipedia.org/wiki/Embossing)

Create accurate embossed surfaces from images. Make sure that the following conditions are met.

1. Create the embossed image using triangle strings.

2. Create the embossed image using an optimal mesh (decimate or insert points as necessary) that has well shaped triangles (the algorithm demonstrated in class will generate slivers that are not acceptable).

3. Redo the images using NURBS patches.

Light, shade, add material (texture is a bonus) to these surfaces and pop them up on screen.
