Subdivision Zoo

Mesh-related Pre-Submission (due Sun Nov 18)

You are required to submit a preliminary version of the final project up to but not including the subdivision algorithm. Please submit source code and a brief write-up describing your mesh data structure implementation that includes:
• OBJ file format parser capable of parsing either triangle or quad meshes, and that works on the test OBJ files above.
• You can also find plenty of free OBJ models online, e.g., TurboSquid.
• Mesh adjacency datastructure that works with the (tri or quad) test meshes.
• Render the mesh datastructure's contents to illustrate that the mesh has been constructed properly using OpenGL.
• Use display lists to make rendering interactive.
• Use smooth shading using per-vertex normals computed from either the subdivision scheme, e.g., Loop limit-surface normals, or using traditional face-averaged normals.
• Export your (subdivided) mesh in the msh format to support ray-traced rendering in your RayII assignment.  The msh format is described in the RayII handout as follows:
• The msh mesh file contains text as follows, one word or number per line:
• The number of vertices in the mesh.
• The number of triangles in the mesh.
• The keyword vertices
• The 3D coordinates of the vertices, ordered by vertex number: x0, y0, z0, x1, y1, z1, . . ..
• The keyword triangles
• Three integer vertex indices per triangle.
• (Optional) The keyword texcoords, followed by u and v coordinates for each vertex.
• (Optional) The keyword normals, followed by x, y, and z components of a normal vector for each vertex.
• Code that reads the msh format is in the Mesh class of the Model assignment framework.
• Example msh files are provided in the RayII test scenes.  A simple example is bunny500.msh
• Submit your pre-submission materials via CMS for CS 466.
