Set up

Points: 0

Use Perspective projection, set the field of view angle to be 45 degree, near plane to be 0.1 and far plane to be 100.
Camera movements from Project 2: Use ← and → keys move the camera along the blue circle parallel to the equator. ↑ and ↓ keys rotate the camera along the red circle orthogonal to the equator. Point the camera always to the origin. Choose a good "up" direction.
The r key resets the program to its startup state (displays x-y plane, clear rotations, etc.).

Task 1: Display face net

Points: 12+3

Choose a face geometry mesh, not too fine, and place into the scene

If the mesh has quads, show them (not triangles) for full points. Note that your choice here will influence your choice of subdivision algorithm in Task 3.

The f key toggles show/hide of the wireframe of the model

Task 2: Add a texture

Points: 0+12+3

Take a photo of your face
Map the photo onto the mesh facets. Flattening may be useful.
The F key toggles show/hide of the facetted (Frankenstein) head with texture

BONUS:

Points: 40

(Points: 20) Render a smooth surface with the wireframe as a subdivision surface control net.

Choose one of: Catmull-Clark subdivision, Doo-Sabin subdivision, Loop subdivision, quadratic-attraction subdivision , 4-3 subdivision , polyhedral net splines ,

(Points: 15) uv-map your face texture onto the curved surface.
The P key toggles show/hide of the smoothly rendered head ( = with subdivision level at least 2)
The u key toggles show/hide of the texture.

(Points: 5) Animate the front your face to show a smile.

WHAT TO SUBMIT

as for previous projects: explain per Task in the video and Readme.txt.

Filepaths to load models must be relative to the source directory (no absolute paths specific to your computer). Use a "models" folder within the top-most level of the source repo ("ogl-master"). If you need to deviate specify the location in the readme file.
