Trait glitter::shader::ContextShaderBuilderExt [−] [src]

pub trait ContextShaderBuilderExt: AContext + Sized {
    fn build_shader<'a>(
        &'a self, 
        ty: ShaderType, 
        source: &'a str
    ) -> ShaderBuilder<'a, Self>;

    fn build_fragment_shader<'a>(
        &'a self, 
        source: &'a str
    ) -> ShaderBuilder<'a, Self> { ... }

    fn build_vertex_shader<'a>(
        &'a self, 
        source: &'a str
    ) -> ShaderBuilder<'a, Self> { ... }
}

An extension trait for ContextOf that adds functions to build shaders using the ShaderBuilder interface.

Required Methods

Build a new shader with the provided shader type and shader source.

Example

#[macro_use] extern crate glitter;
use glitter::prelude::*;

let vertex_source = r##"#version 100
    attribute vec4 position;

    void main() {
        gl_Position = position;
        _color = color;
    }
"##;

let gl = unsafe { glitter::Context::current_context() };
let shader = gl.build_shader(glitter::VERTEX_SHADER, vertex_source).unwrap();

Provided Methods

Build a new fragment shader with the provided shader source.

Example

#[macro_use] extern crate glitter;
use glitter::prelude::*;

let fragment_source = r##"#version 100
    void main() {
        gl_FragColor = vec4(1.0, 0.0, 0.0, 0.0);
    }
"##;

let gl = unsafe { glitter::Context::current_context() };
let shader = gl.build_fragment_shader(fragment_source).unwrap();

Build a new vertex shader with the provided shader source.

Example

#[macro_use] extern crate glitter;
use glitter::prelude::*;

let vertex_source = r##"#version 100
    attribute vec4 position;

    void main() {
        gl_Position = position;
        _color = color;
    }
"##;

let gl = unsafe { glitter::Context::current_context() };
let shader = gl.build_vertex_shader(vertex_source).unwrap();
