A Qt3DRender::QClearBuffers FrameGraph node enables clearing of the specific render target buffers with specific values.
This enum type describes types of buffer to be cleared.
常量 | 值 | 描述 |
---|---|---|
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.
Specifies the buffer type to be used.
