data Geometry is

A set of attributes and indices.

Constructors

Geometry (AttrList is) [Word16] Int

Instances

Eq (Geometry is)

Hashable (Geometry is)

data Mesh is where

A static or dinamic geometry.

Constructors

Empty :: Mesh []

Cube :: Mesh Geometry3

StaticGeom :: Geometry is -> Mesh is

DynamicGeom :: Geometry is -> Geometry is -> Mesh is

data Object gs is where

An object is a set of geometries associated with some uniforms. For example, if you want to draw a rotating cube, its vertices, normals, etc. would be the Geometry, the combination of the geometry and the value of the model matrix would be the Object, and the combination of the object with a Program would be the Layer. In fact, Objects are just descriptions of the actions to perform to draw something. Instead, the Element types in FWGL.Graphics.D2 and FWGL.Graphics.D3 represent managed (high level) objects, and they are ultimately converted to them.

Constructors

ObjectEmpty :: Object gs is

ObjectMesh :: Mesh is -> Object gs is

ObjectGlobal :: (Typeable g, UniformCPU c g) => g -> Draw c -> Object gs is -> Object gs' is

ObjectAppend :: Object gs is -> Object gs' is' -> Object gs'' is''

data Layer

An object associated with a program. It can also be a layer included in another.

Constructors

SubLayer Int Int Layer (Texture -> [Layer])
