void shadeAtmPixel	(	struct SunSky *	sunsky,
		float *	collector,
		float	fx,
		float	fy,
		float	distance
	)

Referenced by atm_tile().

int shadeHaloFloat	(	HaloRen *	har,
		float *	col,
		int	zz,
		float	dist,
		float	xn,
		float	yn,
		short	flarec
	)

Render the pixel at (x,y) for object ap. Apply the jitter mask. Output is given in float collector[4]. The type vector: t[0] - min. distance t[1] - face/halo index t[2] - jitter mask t[3] - type ZB_POLY or ZB_HALO t[4] - max. distance mask is pixel coverage in bits

Returns:

pointer to the object

Parameters:

col	(float[4]) Store the rgb color here (with alpha) The alpha is used to blend the color to the background color_new = (1-alpha)*color_background + color
zz	The current zbuffer value at the place of this pixel
dist	Distance of the pixel from the center of the halo squared. Given in pixels
xn	The x coordinate of the pixel relaticve to the center of the halo. given in pixels
yn	The y coordinate of the pixel relaticve to the center of the halo. given in pixels
