Member Function Documentation

beginFrame()

virtual void Cogs::ISwapChain::beginFrame ( )

pure virtual

Signal the beginning of a new frame to the graphics device.

Implemented in Cogs::SwapChainD3D11, Cogs::SwapChainGL20, and Cogs::SwapChainWebGPU.

endFrame()

virtual void Cogs::ISwapChain::endFrame ( uint32_t  syncInterval = 0, uint32_t  presentFlags = PresentFlags::None  )

pure virtual

Signal the end of a frame to the graphics device.

When the graphics device itself is responsible for managing the device context (e.g in D3D11), and the PresentFlags::NoSwap flag is not set, this will swap the back buffer to make the result of previous drawing visible.

Parameters

syncInterval	Synchronization interval. 0 - No synchronization, presentation occurs immediately. 1 - Synchronize presentation after 1 vertical blank.
presentFlags	A combination of PresentFlags controlling the presentation of the rendered frame.

setSize()

virtual void Cogs::ISwapChain::setSize ( int  newWidth, int  newHeight, bool  forceIt = false  )

pure virtual

Set the size of the main drawing buffer used by the graphics device in pixels.

Parameters

newWidth	Width of the drawing buffer in pixels.
newHeight	Height of the drawing buffer in pixels.
forceIt	Force the resize even if the new width and height are identical to the existing values.

Implemented in Cogs::SwapChainD3D11, Cogs::SwapChainGL20, and Cogs::SwapChainWebGPU.
