Detailed Description

Creates a Red seamless 2D image with random metastars.

Constructor & Destructor Documentation

oglplus::images::RandomMetastars::RandomMetastars	(	GLsizei	width,
		GLsizei	height,
		std::size_t	count,
		GLfloat	rad_min,
		GLfloat	rad_max,
		GLfloat	dif_min,

	)

Creates an image with the specified dimensions and params.

Parameters

width	the width of the image
height	the height of the image
count	the number of metastars to be generated.
rad_min	the minimum radius of a metaball normalized to (0, 1).
rad_max	the maximum radius of a metaball normalized to (0, 1).
