Method Summary

Modifier and Type	Method and Description
<A,B,E extends Throwable> B	matchShadow(A context, com.io7m.jfunctional.PartialBiFunctionType<A,R2ShadowDepthVarianceType,B,E> on_variance) Match on the type of light.

Method Detail

shadowID

long shadowID()

Returns:

The unique shadow ID

minimumFactor

default float minimumFactor()

The level to which the shadow is allowed to attenuate light. A value of n means that if a point is in shadow, the light intensity will be attenuated down to n.

Returns:

The minimum shadow factor

matchShadow

<A,B,E extends Throwable> B matchShadow(A context,
                                        com.io7m.jfunctional.PartialBiFunctionType<A,R2ShadowDepthVarianceType,B,E> on_variance)

E - The type of raised exceptions

Parameters:

context - A context value

on_variance - Evaluated for variance shadows

Returns:

A value of type B

Throws:

E - If any of the given functions raise E
