Member Function Documentation

◆ determineResolution()

void blender::compositor::TrackPositionOperation::determineResolution	(	unsigned int	resolution[2],
		unsigned int	preferredResolution[2]
	)

overrideprotectedvirtual

Determine the output resolution. The resolution is retrieved from the Renderer

Reimplemented from blender::compositor::NodeOperation.

Definition at line 134 of file COM_TrackPositionOperation.cc.

◆ executePixelSampled()

void blender::compositor::TrackPositionOperation::executePixelSampled	(	float	[4],
		float	,
		float	,
		PixelSampler
	)

overridevirtual

calculate a single pixel

Note: this method is called for non-complex

Parameters

result	is a float[4] array to store the result
x	the x-coordinate of the pixel to calculate in image space
y	the y-coordinate of the pixel to calculate in image space
inputBuffers	chunks that can be read by their ReadBufferOperation.
