Detailed Description
A Qt3DRender::QClearBuffers FrameGraph node enables clearing of the specific render target buffers with specific values.
Member Type Documentation
enum QClearBuffers::BufferType
flags QClearBuffers::BufferTypeFlags
This enum type describes types of buffer to be cleared.
Constant | Value | Description |
---|---|---|
Qt3DRender::QClearBuffers::None | 0 | No buffers will be cleared |
Qt3DRender::QClearBuffers::ColorBuffer | (1 << 0) | Clear color buffers |
Qt3DRender::QClearBuffers::DepthBuffer | (1 << 1) | Clear depth buffer |
Qt3DRender::QClearBuffers::StencilBuffer | (1 << 2) | Clear stencil buffer |
Qt3DRender::QClearBuffers::DepthStencilBuffer | DepthBuffer | StencilBuffer | Clear depth and stencil buffers |
Qt3DRender::QClearBuffers::ColorDepthBuffer | ColorBuffer | DepthBuffer | Clear color and depth buffers |
Qt3DRender::QClearBuffers::ColorDepthStencilBuffer | ColorBuffer | DepthStencilBuffer | Clear color, depth and stencil buffers |
Qt3DRender::QClearBuffers::AllBuffers | 0xFFFFFFFF | Clear all buffers |
The BufferTypeFlags type is a typedef for QFlags<BufferType>. It stores an OR combination of BufferType values.
