data Geometry is

A set of attributes and indices.

Instances

Eq (Geometry is)

Methods

(==) :: Geometry is -> Geometry is -> Bool

(/=) :: Geometry is -> Geometry is -> Bool

Hashable (Geometry is)

Methods

hashWithSalt :: Int -> Geometry is -> Int

hash :: Geometry is -> Int

emptyGeometry

Arguments

:: [Word16]

Triangles.

-> Geometry '[]

Create a Geometry without attributes. You can add them using extend.

extend

Arguments

:: (Attribute S i, Hashable (CPU S i), ShaderType i, GLES)

=> (a -> i)

Attribute constructor (or any other function with that type).

-> [CPU S i]

List of values

-> Geometry is

-> Geometry (i ': is)

Add an attribute to a geometry.

remove

Arguments

:: (RemoveAttr i is is', GLES)

=> (a -> i)

Attribute constructor (or any other function with that type).

-> Geometry is

-> Geometry is'

Remove an attribute from a geometry.

2D and 3D geometries

type Geometry2D = '[Position2, UV]

A 2D geometry.

type Geometry3D = '[Position3, UV, Normal3]

A 3D geometry.

mkGeometry2D

Arguments

:: GLES

=> [Vec2]

List of vertices.

-> [Vec2]

List of UV coordinates.

-> [Word16]

Triangles expressed as triples of indices to the two lists above.

-> Geometry Geometry2D

Create a 2D Geometry. The first two lists should have the same length.

mkGeometry3D

Arguments

:: GLES

=> [Vec3]

List of vertices.

-> [Vec2]

List of UV coordinates.

-> [Vec3]

List of normals.

-> [Word16]

Triangles expressed as triples of indices to the three lists above.

-> Geometry Geometry3D

Create a 3D Geometry. The first three lists should have the same length.

positionOnly :: Geometry Geometry3D -> Geometry '[Position3]

Remove the UV and Normal3 attributes from a 3D Geometry.
