virtual HGI_API bool | _Submit (Hgi *hgi) |
A graphics API independent abstraction of graphics commands. HgiGraphicsCmds is a lightweight object that cannot be re-used after it has been submitted. A new cmds object should be acquired for each frame.

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().
Implemented in HgiGLGraphicsCmds.

pure virtual |
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.
Implemented in HgiGLGraphicsCmds.

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.
Implemented in HgiGLGraphicsCmds.

Records a draw command that renders one or more instances of primitives using an indexBuffer starting from the base vertex of the base instance. indexCount
is the number of vertices. indexBufferByteOffset
: Byte offset within indexBuffer to start reading indices from. vertexOffset
: the value added to the vertex index before indexing into the vertex buffer (baseVertex). instanceCount
: number of instances (min 1) of the primitves to render.
Implemented in HgiGLGraphicsCmds.
Pop the last debug marker.

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. byteSize
is the size of the data you are updating. data
is the data you are copying into the push constants block.
Implemented in HgiGLGraphicsCmds.
Only pixels that lie within the scissor box are modified by drawing commands.
Implemented in HgiGLGraphicsCmds.
Set viewport [left, BOTTOM, width, height] - OpenGL coords.
Implemented in HgiGLGraphicsCmds.
