 ICamera camera,
 double t,
 RenderingContext rc)

Specified by:

render in interface IRenderSystem

getAlpha

public float getAlpha(IRenderable renderable)

Computes the alpha opacity value of a given renderable using its component types

Parameters:

renderable - The renderable

Returns:

The alpha value as the product of all the alphas of its component types.

getAlpha

public float getAlpha(ComponentTypes ct)

resize
