Detailed Description

Mesh pipeline state descriptor structure.

Remarks

This structure describes the entire mesh-based graphics pipeline. Unlike the traditional graphics pipeline, the mesh pipeline provides two new shader stages: amplification and mesh shaders. These replace the traditional shader and fixed-function stages for vertex processing. Only the fragment shader remains from the traditional PSO.

Note

Only supported with: Direct3D 12.

Member Data Documentation

amplificationShader

Shader* LLGL::MeshPipelineDescriptor::amplificationShader = nullptr

Deprecated

Since 0.05b; Use taskShader instead!

blend

BlendDescriptor LLGL::MeshPipelineDescriptor::blend

Specifies the state descriptor for the blend stage.

debugName

const char* LLGL::MeshPipelineDescriptor::debugName = nullptr

Optional name for debugging purposes. By default null.

Remarks

The final name of the native hardware resource is implementation defined.

RenderSystemChild::SetDebugName

depth

DepthDescriptor LLGL::MeshPipelineDescriptor::depth

Specifies the depth state for the depth-stencil stage.

fragmentShader

Shader* LLGL::MeshPipelineDescriptor::fragmentShader = nullptr

Specifies an optional fragment shader (also referred to as "Pixel Shader").

Remarks

If no fragment shader is specified, generated fragments are discarded by the output merger and only the stream-output functionality as well as depth writes are used by either the vertex or geometry shader. If a depth buffer is attached to the current render target, omitting the fragment shader can be utilized to render a standard shadow map.

meshShader

Shader* LLGL::MeshPipelineDescriptor::meshShader = nullptr

Specifies the mesh shader.

Remarks

This is mandatory for mesh PSOs.

pipelineLayout

const PipelineLayout* LLGL::MeshPipelineDescriptor::pipelineLayout = nullptr

Specifies an optional pipeline layout for the graphics pipeline. By default null.

Remarks

This layout determines at which slots buffer resources will be bound. If this is null, a default layout will be used that is only compatible with graphics pipelines that have no binding points, i.e. no input/output buffers or textures.

RenderSystem::CreatePipelineLayout

rasterizer

RasterizerDescriptor LLGL::MeshPipelineDescriptor::rasterizer

Specifies the state for the rasterizer stage.

renderPass

const RenderPass* LLGL::MeshPipelineDescriptor::renderPass = nullptr

Specifies an optional render pass. By default null.

Remarks

If this is null, the render pass of the SwapChain that was first created is used. This render pass must be compatible with the one passed to the CommandBuffer::BeginRenderPass function in which the graphics pipeline will be used.

CommandBuffer::BeginRenderPass

RenderSystem::CreateRenderPass

scissors

DynamicVector<Scissor> LLGL::MeshPipelineDescriptor::scissors

Specifies an optional list of static scissor rectangles. If empty, the scissors must be set dynamically with the command buffer.

Remarks

This list must have the same number of entries as viewports, unless one of the lists is empty.

CommandBuffer::SetScissor

CommandBuffer::SetScissors

stencil

StencilDescriptor LLGL::MeshPipelineDescriptor::stencil

Specifies the stencil state for the depth-stencil stage.

taskShader

Shader* LLGL::MeshPipelineDescriptor::taskShader = nullptr

Specifies an optional task shader.

Remarks

This is optional to further optimize the PSO.

viewports

DynamicVector<Viewport> LLGL::MeshPipelineDescriptor::viewports

Specifies an optional list of static viewports. If empty, the viewports must be set dynamically with the command buffer.

Remarks

This list must have the same number of entries as scissors, unless one of the lists is empty.
