Graphics.Rendering.Ombra.D2

Simplified 2D graphics system.

2D Objects

type Object2D = Object Uniforms2D Geometry2D

A simple 2D Object, without the View2 matrix.

type IsObject2D gs is = (Subset Geometry2D is, Subset (View2 ': Uniforms2D) gs, ShaderVars is, ShaderVars gs)

2D objects compatible with the standard 2D shader program.

rect :: GLES => Texture -> Object2D

A rectangle with a specified Texture.

image :: GLES => Texture -> Object2D

A rectangle with the aspect ratio adapted to its texture.

sprite :: GLES => Texture -> Object2D

A rectangle with the size and aspect ratio adapted to the screen, assuming that you're using viewScreen or screenMat3.

depth :: (MemberGlobal Depth gs, GLES) => Float -> Object gs is -> Object gs is

Set the depth of a 2D Object.

poly :: GLES => Texture -> Geometry is -> Object Uniforms2D is

A 2D object with a specified Geometry.

Transformations

trans :: (MemberGlobal Transform2 gs, GLES) => Vec2 -> Object gs is -> Object gs is

Translate a 2D Object.

rot :: (MemberGlobal Transform2 gs, GLES) => Float -> Object gs is -> Object gs is

Rotate a 2D Object.

scale :: (MemberGlobal Transform2 gs, GLES) => Float -> Object gs is -> Object gs is

Scale a 2D Object.

scaleV :: (MemberGlobal Transform2 gs, GLES) => Vec2 -> Object gs is -> Object gs is

Scale a 2D Object in two dimensions.

scaleTex :: (MemberGlobal Transform2 gs, GLES) => Texture -> Object gs is -> Object gs is

Scale an Object so that it has the same size as the Texture, assuming viewScreen or screenMat3.

scaleTexAR :: (MemberGlobal Transform2 gs, GLES) => Texture -> Object gs is -> Object gs is

Scale an Object so that it has the same aspect ratio as the Texture

scaleV $ Vec2 1 (texture height / texture width).

transform :: (MemberGlobal Transform2 gs, GLES) => Mat3 -> Object gs is -> Object gs is

Transform a 2D Object.

Layers

view :: (ShaderVars gs, ShaderVars is, GLES) => Mat3 -> [Object gs is] -> Object (View2 ': gs) is

Create a group of objects with a view matrix.

viewScreen :: (ShaderVars gs, ShaderVars is, GLES) => Mat3 -> [Object gs is] -> Object (View2 ': gs) is

Create a group of objects with a view matrix and screenMat3.

viewVP :: (ShaderVars gs, ShaderVars is, GLES) => (Vec2 -> Mat3) -> [Object gs is] -> Object (View2 ': gs) is

Create a group of objects with a view matrix, depending on the size of the framebuffer.

layerS :: IsObject2D gs is => Object gs is -> Layer' s t ()

A Layer with the standard 2D program.
