Struct luminance::shading_gate::ShadingGate

pub struct ShadingGate<'a, B> where
    B: ?Sized,  { /* fields omitted */ }

A shading gate.

This is obtained after entering a PipelineGate.

Parametricity

• B is the backend type.

Implementations

impl<'a, B: ?Sized> ShadingGate<'a, B> where
    B: ShadingGateBackend, 

pub fn shade<E, Sem, Out, Uni, F>(
    &mut self,
    program: &mut Program<B, Sem, Out, Uni>,
    f: F
) -> Result<(), E> where
    Sem: Semantics,
    Uni: UniformInterface<B>,
    F: for<'b> FnOnce(ProgramInterface<'b, B>, &'b Uni, RenderGate<'b, B>) -> Result<(), E>, 

Enter a ShadingGate by using a shader Program.

The argument closure is given two arguments:

• A ProgramInterface, that allows to pass values (via ProgramInterface::set) to the in-use shader Program and/or perform dynamic lookup of uniforms.
• A RenderGate, allowing to create deeper nodes in the graphics pipeline.
