Detailed Description

a very thin wrapper to DirectX device with a portable version of openGL implementation.

functions include drawing primitives, binding textures, setting blending operations, etc. This wrapper is made as thin as possible, so that one can use native DirectX or openGL api with this class.

Member Function Documentation

§ BeginRenderTarget()

void ParaEngine::RenderDevice::BeginRenderTarget	(	int	nWidth,
		int	nHeight
	)

this is only used by Opengl render target.

§ CheckRenderError() [1/2]

bool ParaEngine::RenderDevice::CheckRenderError	(	const char *	filename = `NULL`,
		const char *	func = `NULL`,
		int	nLine = `0`
	)

static

check render error and print to log.

only call this in debug mode, since it breaks parallelism between gpu and cpu.

§ CheckRenderError() [2/2]

static bool ParaEngine::RenderDevice::CheckRenderError	(	const char *	filename = `NULL`,
		const char *	func = `NULL`,
		int	nLine = `0`
	)

static

check render error and print to log.

only call this in debug mode, since it breaks parallelism between gpu and cpu.

§ ReadPixels() [1/2]

bool ParaEngine::RenderDevice::ReadPixels	(	int	nLeft,
		int	nTop,
		int	nWidth,
		int	nHeight,
		void *	pDataOut,
		DWORD	nDataFormat = `0`,
		DWORD	nDataType = `0`
	)

static

read a block of pixels from the frame buffer this emulate: glReadPixels().

§ ReadPixels() [2/2]

static bool ParaEngine::RenderDevice::ReadPixels	(	int	nLeft,
		int	nTop,
		int	nWidth,
		int	nHeight,
		void *	pDataOut,
		DWORD	nDataFormat = `0`,
		DWORD	nDataType = `0`
	)

static

read a block of pixels from the frame buffer this emulate: glReadPixels().
