void OivDepthPeelingOutputColor	(	vec4	color,
		vec3	coords
	)

By default the depth generated by the rasterizer (gl_FragCoord.z) is used, but some algorithms may modify the depth in the fragment shader.

In these cases gl_FragCoord.z is not valid and the user-defined depth coordinate must be explicitly specified in the 'coords' parameter.

void OivDepthPeelingOutputColor

(

vec4

color

)

When depth peeling is enabled, OivDepthPeelingOutputColor must be called instead of setting 'gl_FragColor' since some depth peeling techniques use MRTs (multiple render targets) or premultiply the color by the alpha value (on-the-fly blending for example).
