iandol / CreateProceduralSineSmoothedGrating.m

Created February 18, 2011 20:21

Add a cosine (method = 0) or hermite (method = 1) smoothed edge to a circularly masked sine grating. sigma is the width of the smoothing in pixels to apply to the edge. You can set useAlpha = 0 to modulate only colour, or useAlpha = 1 to modulate alpha.

	function [gratingid, gratingrect] = CreateProceduralSineSmoothedGrating(windowPtr, width, height, backgroundColorOffset, radius, contrastPreMultiplicator, sigma, useAlpha, method)
	% [gratingid, gratingrect] = CreateProceduralSineGrating(windowPtr, width, height [, backgroundColorOffset =(0,0,0,0)] [, radius=inf][, contrastPreMultiplicator=1])
	%
	% Creates a procedural texture that allows to draw sine grating stimulus patches
	% in a very fast and efficient manner on modern graphics hardware.
	%
	% 'windowPtr' A handle to the onscreen window.
	% 'width' x 'height' The maximum size (in pixels) of the grating. More
	% precise, the size of the mathematical support of the grating. Providing too
	% small values here would 'cut off' peripheral parts or your grating. Too big
