Detailed Description

This channel is used to link textures or data maps.

It stores a texture id.

Member Function Documentation

void RenderPass::TextureChannel::freeTexture

(

)

Tells the channel that it will not be updated anymore.

Removes the texture from the GPU and sets the Channel inactive. Uses OpenGL calls and might delete the Channel - do not try to access this Channel after this call.

GLuint RenderPass::TextureChannel::getID

(

)

Getter for the OpenGL texture id.

Returns

The id.

void RenderPass::TextureChannel::reserveDepthTexture	(	unsigned int	x,
		unsigned int	y
	)

Reserves a new depth map on the GPU.

Uses OpenGL calls. Deletes the current texture.

Parameters

x	The x-resolution of the depth map.
y	The y-resolution of the depth map.

void RenderPass::TextureChannel::reserveTexture	(	unsigned int	x,
		unsigned int	y,
		bool	floatPrecision
	)

Reserves a new texture on the GPU.

Uses OpenGL calls. Deletes current texture.

Parameters

x	The x-resolution of the texture.
y	The y-resolution of the texture.
floatPrecision	true if the texture shall be in floating point precision.
