Documentation
class BufferFormat a => UniformInput a where Source #
This class constraints which buffer types can be loaded as uniforms, and what type those values have.
Associated Types
type UniformFormat a x Source #
The type the buffer value will be turned into once it becomes a vertex or fragment value (the x parameter is either V or F).
Methods
toUniform :: ToUniform x a (UniformFormat a x) Source #
An arrow action that turns a value from it's buffer representation to it's vertex or fragment representation. Use toUniform from
the GPipe provided instances to operate in this arrow. Also note that this arrow needs to be able to return a value
lazily, so ensure you use
proc ~pattern -> do ....
