Assignment 2: Sample Screenshots

Some example worlds with screenshots. Note that screenshots were taken from whatever angle I could find that best captured the scene. Your output doesn't have to look exactly like this, but the following elements should match:

  1. the shape of the terrain
  2. the direction of the lighting
  3. the shape of the road
I have included the line outlines of the triangles only so you can see the geometry of the terrain.

Tree Interpolation

  • It is ok to place the centre of the trunk at the interpolated y-value. You will not lose any marks for this, but it is obviously better to fix it
