Framebuffer batch

data FBBatch rw c d

Framebuffer batch.

A FBBatch is used to expose a Framebuffer and share it between several shader program batches.

framebufferBatch :: Framebuffer rw c d -> [AnySPBatch rw c d] -> FBBatch rw c d

Share a Framebuffer between several shader program batches.

Shader program batch

data SPBatch rw c d u v

Shader Program batch.

Such a batch is used to share a Program between several RenderCmd. It also gathers a uniform U u and a u value to send to the uniform.

The u type can be used to send uniforms for the whole batch. It can be useful for cold values – that won’t change very often for a given frame – like the resolution of the screen, the mouse cursor coordinates, the time, and so on and so forth.

The v type variable is used to add uniforms per-RenderCmd.

data AnySPBatch rw c d

Abstract SPBatch over uniform interface.

anySPBatch :: SPBatch rw c d u v -> AnySPBatch rw c d

Abstract SPBatch.

shaderProgramBatch :: Program -> U u -> u -> [RenderCmd rw c d v Geometry] -> SPBatch rw c d u v

Create a new SPBatch.

shaderProgramBatch_ :: Program -> [RenderCmd rw c d v Geometry] -> SPBatch rw c d () v

Create a new SPBatch with no uniform interface.
