Description

Currently, you can parse a file and get a WavefrontOBJ with the fromFile function.

Synopsis

Vertex location

data Location Source #

A location is a 4-floating vector. You can access to its components by pattern matching on them:

  let Location x y z w = Location 1 2 3 4

That type is strict and unboxed.

Vertex texture coordinates

data TexCoord Source #

A texture coordinate is a 3D-floating vector. You can access to its components by pattern matching on them:

  let TexCoord r s t = TexCoord 0.1 0.2 0.3

That type is strcit and unboxed.

Vertex normals

data Normal Source #

A normal is a 3-floating vector. You can access to its components by pattern matching on them:

  let Normal nx ny nz = Normal 0.1 0.2 0.3

That type is strict and unboxed.

Points

data Point Source #

A point is a single index that references the locations. It’s a canonical type that truly represents a polygonal point.

data LineIndex Source #

A line index is a pair of indices. LineIndex vi vti. vi references the locations and vti indexes the texture coordinates. If vti == Nothing, then that LineIndex doesn’t have texture coordinates associated with.

Faces

data Face Source #

A face gathers several FaceIndex to build up faces. It has a least three vertices

show :: Face -> String #

showList :: [Face] -> ShowS #

data FaceIndex Source #

A face index is a triplet of indices. FaceIndex vi vti vni is a face that indexes the locations with vi, the texture coordinates with vti and the normals with vni. An index set to Nothing means no information. That is, if vni == Nothing, then that FaceIndex doesn’t have a normal associated with.

Element

data Element a Source #

An element holds a value along with the user-defined object’s name (if any), the associated groups, the used material and the smoothing group the element belongs to (if any). Those values can be used to sort the data per object or per group and to lookup materials.
