Draw color values from a FragmentStream into the context window.

Perform a depth test for each fragment from a FragmentStream in the context window. This doesn't draw any color values and only affects the depth buffer.

Perform a depth test for each fragment from a FragmentStream and write a color value from each fragment that passes the test into the context window.

Perform a stencil test for each fragment from a FragmentStream in the context window. This doesn't draw any color values and only affects the stencil buffer.

Perform a stencil test for each fragment from a FragmentStream and write a color value from each fragment that passes the test into the context window.

Perform a stencil test and depth test (in that order) for each fragment from a FragmentStream in the context window. This doesnt draw any color values and only affects the depth and stencil buffer.

Perform a stencil test and depth test (in that order) for each fragment from a FragmentStream and write a color value from each fragment that passes the tests into the context window.

Draw all fragments in a FragmentStream using the provided function that passes each fragment value into a DrawColors monad. The first argument is a function that retrieves a Blending setting from the shader environment, which will be used for all drawColor actions in the DrawColors monad where UseBlending is True. (OpenGl 3.3 unfortunately doesn't support having different blending settings for different color targets.)

Like draw, but performs a depth test on each fragment first. The DrawColors monad is then only run for fragments where the depth test passes.

Draw color values into a color renderable texture image.

A monad in which individual color images can be drawn.

A texture image is a reference to a 2D array of pixels in a texture. Some textures contain one Image per level of detail while some contain several.

Compare two images that doesn't necessarily has same type

Retrieve the 2D size an image

Fill the context window's back buffer with a constant color value

Fill the context window's back depth buffer with a constant depth value (in the range [0,1])

Fill the context window's back stencil buffer with a constant stencil value

Fill the context window's back depth and stencil buffers with a constant depth value (in the range [0,1]) and a constant stencil value

Fill a color image with a constant color value

Fill a depth image with a constant depth value (in the range [0,1])

Fill a depth image with a constant stencil value

Fill a combined depth stencil image with a constant depth value (in the range [0,1]) and a constant stencil value

True for each color component that should be written to the target.

Indicates whether this color draw should use the Blending setting given to the draw action. If this is False, the fragment's color value will simply replace the target value.

Denotes how each fragment's color value should be blended with the target value.

A set of blending factors used for the source (fragment) and the destination (target).

The equation used to combine the source (fragment) and the destination (target) after they have been multiplied with their respective BlendingFactors.

A factor that the source (fragment) or the destination (target) will be multiplied with before combined with the other in the BlendEquation.

A bitwise logical operation that will be used to combine colors that has an integral internal representation.

True if the depth component should be written to the target.

The function used to compare the fragment's depth and the depth buffers depth with. E.g. Less means "where fragment's depth is less than the buffers current depth".

Denotes the operation that will be performed on the target's stencil value
