overridevirtual |
Bind a pipeline state object.
Usually you call this right after calling CreateGraphicsCmds to set the graphics pipeline state. The resource bindings used when creating the pipeline must be compatible with the resources bound via BindResources().
Implements HgiGraphicsCmds.
|
overridevirtual |
Bind resources such as textures and uniform buffers.
Usually you call this right after BindPipeline() and the resources bound must be compatible with the bound pipeline.
Implements HgiGraphicsCmds.
|
overridevirtual |
Binds the vertex buffer(s) that describe the vertex attributes.
firstBinding the first index to which buffers are bound (usually 0). byteOffsets offset to where the data of each buffer starts, in bytes. strides the size of a vertex in each of the buffers.
Implements HgiGraphicsCmds.
|
overridevirtual |
Records a draw command that renders one or more instances of primitives using the number of vertices provided.
The 'primitive type' (eg. Lines, Triangles, etc) can be acquired from the bound HgiPipeline. vertexCount: The number of vertices to draw. firstVertex: The index of the first vertex to draw. instanceCount: Number of instances to draw.
Implements HgiGraphicsCmds.

overridevirtual |
Records a draw command that renders one or more instances of primitives using an indexBuffer starting from the base vertex.
The 'primitive type' (eg. Lines, Triangles, etc) can be acquired from the bound HgiPipeline. indexCount: The number of indices in the index buffer (num vertices). indexBufferByteOffset: Byte offset within index buffer to start reading the indices from. vertexOffset: The value added to the vertex index before indexing into the vertex buffer (baseVertex). instanceCount: Number of instances to draw.
Implements HgiGraphicsCmds.
|
overridevirtual |
Records a indexed multi-draw command that reads the draw parameters from a provided drawParameterBuffer, and indices from indexBuffer.
The 'primitive type' (eg. Lines, Triangles, etc) can be acquired from the bound HgiPipeline. drawParameterBuffer: an array of structures: drawBufferOffset: Byte offset where the draw parameters begin. drawCount: The number of draws to execute. stride: byte stride between successive sets of draw parameters.
Implements HgiGraphicsCmds.

| HGIGL_API void InsertFunctionOp | ( | std::function< void(void)> const & | fn | ) |
XXX This function is exposed temporarily for Hgi transition.
It allows code that is not yet converted to Hgi (e.g. HdSt) to insert its opengl calls into the ops-stack of HgiGL to ensure that all commands execute in the correct order. Once HdSt has transition fully to Hgi we should remove this function.

Inserts a barrier so that data written to memory by commands before the barrier is available to commands after the barrier.

Set Push / Function constants.
pipeline is the pipeline that you are binding before the draw call. It contains the program used for the uniform buffer stages describes for what shader stage you are setting the push constant values for. Each stage can have its own (or none) binding and they must match what is described in the shader functions. bindIndex is the binding point index in the pipeline's shader to bind the data to. byteSize is the size of the data you are updating. data is the data you are copying into the push constants block.
Implements HgiGraphicsCmds.
