Description

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

Synopsis

Vertex location

data Location #

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.

Constructors

Location 

Fields

Vertex texture coordinates

data TexCoord #

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.

Constructors

TexCoord 

Vertex normals

data Normal #

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.

Constructors

Normal 

Fields

Instances

Eq Normal # 

Methods

(==) :: Normal -> Normal -> Bool #

(/=) :: Normal -> Normal -> Bool #

Show Normal # 

Points

data Point #

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

Constructors

Point 

Fields

Instances

Eq Point # 

Methods

(==) :: Point -> Point -> Bool #

(/=) :: Point -> Point -> Bool #

Show Point # 

Methods

showsPrec :: Int -> Point -> ShowS #

show :: Point -> String #

showList :: [Point] -> ShowS #

Lines

data Line #

Constructors

Line 

Instances

Eq Line # 

Methods

(==) :: Line -> Line -> Bool #

(/=) :: Line -> Line -> Bool #

Show Line # 

Methods

showsPrec :: Int -> Line -> ShowS #

show :: Line -> String #

showList :: [Line] -> ShowS #

data LineIndex #

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.

Constructors

LineIndex 

Faces

data Face #

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

Instances

Eq Face # 

Methods

(==) :: Face -> Face -> Bool #

(/=) :: Face -> Face -> Bool #

Show Face # 

Methods

showsPrec :: Int -> Face -> ShowS #

show :: Face -> String #

showList :: [Face] -> ShowS #

data FaceIndex #

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.

Constructors

FaceIndex 

Element

data Element a #

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.

Constructors

Element

Eq a => Eq (Element a) #
