Expand description
A combination of compute shaders linked together.
Implementations§
source§impl ComputeShader
impl ComputeShader
sourcepub fn is_supported<C>(ctxt: &C) -> boolwhere
C: CapabilitiesSource + ?Sized,
pub fn is_supported<C>(ctxt: &C) -> boolwhere C: CapabilitiesSource + ?Sized,
Returns true if the backend supports compute shaders.
sourcepub fn from_source<F>(
facade: &F,
src: &str
) -> Result<ComputeShader, ProgramCreationError>where
F: Facade + ?Sized,
pub fn from_source<F>( facade: &F, src: &str ) -> Result<ComputeShader, ProgramCreationError>where F: Facade + ?Sized,
Builds a new compute shader from some source code.
sourcepub fn from_spirv<F>(
facade: &F,
spirv: &SpirvEntryPoint<'_>
) -> Result<ComputeShader, ProgramCreationError>where
F: Facade + ?Sized,
pub fn from_spirv<F>( facade: &F, spirv: &SpirvEntryPoint<'_> ) -> Result<ComputeShader, ProgramCreationError>where F: Facade + ?Sized,
Builds a new compute shader from SPIR-V module.
sourcepub fn from_binary<F>(
facade: &F,
data: Binary
) -> Result<ComputeShader, ProgramCreationError>where
F: Facade + ?Sized,
pub fn from_binary<F>( facade: &F, data: Binary ) -> Result<ComputeShader, ProgramCreationError>where F: Facade + ?Sized,
Builds a new compute shader from some binary.
sourcepub fn execute<U>(&self, uniforms: U, x: u32, y: u32, z: u32)where
U: Uniforms,
pub 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 retrieved with
gl_WorkGroupID
. Inside each work group, additional local work groups can be started
depending on the attributes of the compute shader itself.
sourcepub fn execute_indirect<U>(
&self,
uniforms: U,
buffer: BufferSlice<'_, ComputeCommand>
)where
U: Uniforms,
pub 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.
sourcepub fn get_binary(&self) -> Result<Binary, GetBinaryError>
pub 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.
sourcepub fn get_uniform(&self, name: &str) -> Option<&Uniform>
pub fn get_uniform(&self, name: &str) -> Option<&Uniform>
Returns informations about a uniform variable, if it exists.
sourcepub fn uniforms(&self) -> Iter<'_, String, Uniform>
pub 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);
}
sourcepub fn get_uniform_blocks(
&self
) -> &HashMap<String, UniformBlock, BuildHasherDefault<FnvHasher>>
pub fn get_uniform_blocks( &self ) -> &HashMap<String, UniformBlock, BuildHasherDefault<FnvHasher>>
Returns a list of uniform blocks.
Example
for (name, uniform) in program.get_uniform_blocks() {
println!("Name: {}", name);
}
sourcepub fn get_shader_storage_blocks(
&self
) -> &HashMap<String, UniformBlock, BuildHasherDefault<FnvHasher>>
pub fn get_shader_storage_blocks( &self ) -> &HashMap<String, UniformBlock, BuildHasherDefault<FnvHasher>>
Returns the list of shader storage blocks.
Example
fn example(program: glium::Program) {
for (name, uniform) in program.get_shader_storage_blocks() {
println!("Name: {}", name);
}
