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.
Property Documentation
buffers : BufferType
Specifies the buffer type to be used.
Access functions:
| Qt3DRender::QClearBuffers::BufferType | buffers() const |
| void | setBuffers(Qt3DRender::QClearBuffers::BufferType buffers) |
Notifier signal:
| void | buffersChanged(Qt3DRender::QClearBuffers::BufferType buffers) |
clearColor : QColor
Specifies the clear color to be used.
Access functions:
| QColor | clearColor() const |
| void | setClearColor(const QColor &color) |
Notifier signal:
| void | clearColorChanged(const QColor &color) |
clearDepthValue : float
Specifies the clear depth value to be used.
Access functions:
| float | clearDepthValue() const |
| void | setClearDepthValue(float clearDepthValue) |
Notifier signal:
| void | clearDepthValueChanged(float clearDepthValue) |
clearStencilValue : int
Specifies the stencil value to be used.
Access functions:
