Struct glium::program::ComputeShader
[−]
[src]
pub struct ComputeShader {
// some fields omitted
}A combination of compute shaders linked together.
Methods
impl ComputeShader
fn is_supported<C>(ctxt: &C) -> bool where C: CapabilitiesSource
Returns true if the backend supports compute shaders.
fn from_source<F>(facade: &F, src: &str) -> Result<ComputeShader, ProgramCreationError> where F: Facade
Builds a new compute shader from some source code.
fn from_binary<F>(facade: &F, data: Binary) -> Result<ComputeShader, ProgramCreationError> where F: Facade
Builds a new compute shader from some binary.
fn execute<U>(&self, uniforms: U, x: u32, y: u32, z: u32) where U: Uniforms
Executes the compute shader.
x * y * z work groups will be started. The current work group can be retreived with
gl_WorkGroupID. Inside each work group, additional local work groups can be started
depending on the attributes of the compute shader itself.
fn execute_indirect<U>(&self, uniforms: U, buffer: BufferSlice<ComputeCommand>) where U: Uniforms
Executes the compute shader.
This is similar to execute, except that the parameters are stored in a buffer.
fn get_binary(&self) -> Result<Binary, GetBinaryError>
Returns the program's compiled binary.
You can store the result in a file, then reload it later. This avoids having to compile the source code every time.
fn get_uniform(&self, name: &str) -> Option<&Uniform>
Returns informations about a uniform variable, if it exists.
fn uniforms(&self) -> Iter<String, Uniform>
Returns an iterator to the list of uniforms.
Example
for (name, uniform) in program.uniforms() { println!("Name: {} - Type: {:?}", name, uniform.ty); }
fn get_uniform_blocks(&self) -> &HashMap<String, UniformBlock>
Returns a list of uniform blocks.
Example
for (name, uniform) in program.get_uniform_blocks() { println!("Name: {}", name); }
fn get_shader_storage_blocks(&self) -> &HashMap<String, UniformBlock>
Returns the list of shader storage blocks.
Example
for (name, uniform) in program.get_shader_storage_blocks() { println!("Name: {}", name); }
