Struct radiant_rs::postprocessors::Basic

pub struct Basic { /* fields omitted */ }

A basic postprocessor that applies a Program to the given input once.

Postprocessors are used with Renderer::postprocess(). The associated type for this postprocessor is BlendMode and is expected as second argument to the postprocess() method

Examples

// Load a shader progam.
let my_program = Program::from_string(&rendercontext, &program_source).unwrap();

// Create the postprocessor with the program.
let my_postprocessor = postprocessors::Basic::new(&rendercontext, my_program);

// ... in your renderloop...
renderer.postprocess(&my_postprocessor, &blendmodes::ALPHA, || {
    renderer.clear(Color::BLACK);
    renderer.draw_layer(&my_layer, 0);
});

Methods

impl Basic

pub fn new(context: &RenderContext, program: Program) -> Self

Creates a new instance. The shader can use sheet*() to access the input texture.

Trait Implementations

impl Postprocessor for Basic

type T = BlendMode

The Basic postprocessor accepts a blendmode as argument to Renderer::postprocess().

fn target(&self) -> &Texture

Expected to return a texture for user drawing operations to target.

fn draw(&self, renderer: &Renderer, blendmode: &Self::T)

Expected to draw the final result. Draws issued within this function will target the rendertarget that the postprocessor is supposed to render to.

fn process(&self, renderer: &Renderer, args: &Self::T)

Optionally expected to processes input data. Draws issued within this function will target the texure returned by target() unless overridden via Renderer::render_to().
