Represents a single (valid) OBJ token

TODO | - Polymorphic numerical types (?) - Add context, metadata (eg. line numbers, filename) (?) - Naming scheme (added OBJ prefix to prevent name clashes; cf. Face type) - Comment token (preserve comments in parser output or remove them) (?)

• Cover the entire spec (http:/www.martinreddy.netgfx3dOBJ.spec) (and handle unimplemented attributes gracefully)

TODO: Rename (?) TODO: Use union instead of Maybe (?)

Output type of the OBJ parser.

TODO | - Rename (?) - Use Integral for line number (?)

Represents a single (valid) MTL token

TODO | - Is the alpha channel optional, ignored, disallowed? - Include support for (Ns, Ni, d, Tr, illum) - Assume no colours have an alpha channel, since transparency is handled by the d attribute (?)

1. Color on and Ambient off
2. Color on and Ambient on
3. Highlight on
4. Reflection on and Ray trace on
5. Transparency: Glass on, Reflection: Ray trace on
6. Reflection: Fresnel on and Ray trace on
7. Transparency: Refraction on, Reflection: Fresnel off and Ray trace on
8. Transparency: Refraction on, Reflection: Fresnel on and Ray trace on
9. Reflection on and Ray trace off
10. Transparency: Glass on, Reflection: Ray trace off
11. Casts shadows onto invisible surfaces

Output type of the MTL parser. Currently a list of line number and token (or error string) pairs TODO | - Add type for processed MTL (eg. a map between names and materials)

TODO | - Validation (eg. length ivertices == length == ivertices == length itextures if length isn't 0) - Pack indices in a tuple (eg. indices :: [(Int, Int, Int)]) (?) - Use (String, String) for the names of the mtl file and material instead of Material (?) - Use types so as not to confuse the indices (eg. newtype INormal, newtype ITexcoord)

TODO | - Use a type from the colour package instead (?)

TODO | - Do all materials have an ambient, a diffuse and a specular colour (?) - Support more attributes (entire spec) (?) - Lenses (?)

Abstract representation of an OBJ model with associated MTL definitions.

TODO | - Rename (?) - Include metadata, comments, rejected data (?) - Separate type for processed OBJTokens (ie. token + context) - Perform index lookups (?) - Reconsider the types (especially of the materials) - Rename accessor functions (eg. texcoords instead of textures) (?)
