This module re-exports a number of modules having to do with graphics.

Documentation

newtype Render

A container around IO to suggest that one should perform rendering in a rendering function.

Constructors

Render (IO ())

runRender :: Render -> IO ()

Performing the IO contained in a Render.

class Renderable a where

A class that provides an API to convert a datatype into a Render.

Methods

toRender :: a -> Render

Instances

Renderable Color

Changing the current OpenGL context's Color4 to whatever Color specified.

renderPoint :: Vector Float -> Scene

Rendering a point.

renderRectangle :: Vector Float -> Vector Float -> Scene

Rendering a rectangle.

renderSquare :: Vector Float -> Float -> Scene

Rendering a square.

data Color

Representing a Color using four Float representing reg, green, blue, and the alpha mask respectively. The Floats are in a range from 0-1, representing Ints from 0-255.

Constructors

Color

Fields

getRed :: Float

getGreen :: Float

getBlue :: Float

getAlpha :: Float

Instances

Eq Color

Read Color

Show Color

Renderable Color

Changing the current OpenGL context's Color4 to whatever Color specified.

color4f :: Float -> Float -> Float -> Float -> Scene

A synonym for the Color constructor.

color3f :: Float -> Float -> Float -> Scene

Constructing a Color from 3 Floats, defaulting the alpha mask to 1.0.

color4i :: Int -> Int -> Int -> Int -> Scene

Creating a Color from 4 Ints. The ints, similarly to color4f represent red, green, blue, and the alpha mask respectively. The ints should be in the range of 0-255. (Note: color4i is functionally equivalent (and also equivalent in source code) to calling color4f with each of its arguments divided by 255.)

color3i :: Int -> Int -> Int -> Scene

Constructing a Color from 3 Ints, defaulting the alpha mask to 255.

black :: Scene

The color black.

white :: Scene

The color white.

red :: Scene

The color red.

green :: Scene

The color green.

blue :: Scene

The color blue.

type Scene = SceneT ()

The commonly used instance of SceneT

fromRenderables :: Renderable a => [a] -> Scene

Constructing a SceneT from a list of renderables.

renderScene :: Scene -> IO ()

Rendering a whole Scene (renders each Element from first in list to last in list.)

togl :: Float -> GLfloat

Converting a Float to a GLfloat
