Implementation

• Model bagel, bagel halves, knife
• Add reasonable textures
• Animate movement of objects
• Generate images, merge into video

4
Modeling

• Model halves or whole? (halves)
• Need fine mesh parameterize surface
• Model twisting torus with theta, phi

5
Meshing

• Select local pattern of triangles
• Connect vertex to points in its vicinity
• Avoid duplicate triangles

6
Texture

• Solid colors dont provide relief
• Want realistic colors with intricate pattern
• Idea use high mesh resolution and randomness

7
Animation

• DrawScene() takes in a time parameter
• Call DrawScene(t_i) and write result to .bmp
• Stitch images together using ffmpeg
• Adjust locations/orientations of objects at t_i
  to look nice.
