Project - Surface Subdivision and Tessellation

Set up

• Draw a 600x600 window and set the title to "Yourname".
• 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 geometry as a(n irregular) quad mesh

• Create or find a low poly human head consisting of 3- and 4-sided facets and import it into your openGL program.
• The f key toggles show/hide of the wireframe of the model (show no facets yet!)

Task 2: Add a texture

• Take a photo of your face - Map the photo onto the quad facets of the mesh - The F key toggles show/hide of the facetted (Frankenstein) head with texture

Task 3: Render a smooth surface

• Apply PN triangles and PN quads to the mesh - The P key toggles show/hide of the smoothly rendered head ( = with sufficiently high sample level) - uv-map your face texture onto the front of the curved surface PN quad head model. - The u key toggles show/hide of the texture.

BONUS:

• Use the tessellation engine for Task 3.
