Lines, Triangles, and Surface Tessellation#

Using only the built in method for setting an individual pixel to a color I implemented:

• Bresenham’s Line algorithm to draw a line from one pixel to another.
• Used Bresenham’s Line algorithm to draw a 2D triangle projection of a rotating triangle in 3D space.
• Used 2D triangle projections to tesselate the surface of a 3D rotating sphere.
• Implemented several lighting models for triangles to shade the sphere.

The following are controls used when running the code:

• O: toggles outlines.
• Space: toggles rotation.
• D and E: next and previous display respectively.
• S and W: next and previous shading mode respectively.
