virtual void Resolve()=0
Resolve the buffer so that reads reflect the latest writes.
virtual unsigned int GetWidth() const =0
Get the buffer's width.
virtual void * Map()=0
Map the buffer for reading.
HD_API void Sync(HdSceneDelegate *sceneDelegate, HdRenderParam *renderParam, HdDirtyBits *dirtyBits) override
Get allocation information from the scene delegate.
virtual unsigned int GetHeight() const =0
Get the buffer's height.
virtual bool IsMapped() const =0
Return whether the buffer is currently mapped by anybody.
HD_API void Finalize(HdRenderParam *renderParam) override
Deallocate before deletion.
virtual void _Deallocate()=0
Deallocate the buffer, freeing any owned resources.
virtual void Unmap()=0
Unmap the buffer. It is no longer safe to read from the buffer.
virtual unsigned int GetDepth() const =0
Get the buffer's depth.
virtual bool IsConverged() const =0
Return whether the buffer is converged (whether the renderer is still adding samples or not).
virtual HdFormat GetFormat() const =0
Get the buffer's per-pixel format.
virtual bool IsMultiSampled() const =0
Get whether the buffer is multisampled.
virtual VtValue GetResource(bool multiSampled) const
This optional API returns a (type-erased) resource that backs this render buffer.
HD_API HdDirtyBits GetInitialDirtyBitsMask() const override
Get initial invalidation state.
virtual bool Allocate(GfVec3i const &dimensions, HdFormat format, bool multiSampled)=0
Allocate a buffer.
