Member Function Documentation

ddgFrameBuffer::ddgFrameBuffer (unsigned short ch = 4)

Create an image but don't allocate memory.

ch is the number of channels (1-4). The t flag is true if this is an OpenGL texture which needs to be a power of 2.

bool ddgFrameBuffer::readZBuffer (ddgCamera * c)

Copy the Z-buffer from the screen into the image.

Allocates image to match screen size.

bool ddgFrameBuffer::readFrameBuffer (ddgCamera * c)

Copy the Frame-buffer from the screen into the image.

Allocates image to match screen size.

bool ddgFrameBuffer::readAlphaBuffer (ddgCamera * c)

Copy the Alpha-buffer from the screen into the image.

Allocates image to match screen size.
