Shade an intersection point.

Parameters

aRay	the camera ray that hits the object
aHitInfo	the hit information
NdotL	the dot product between Normal and Light
aDiffuseObjColor	diffuse object color
aDirToLight	a vector of the incident light direction
aLightColor	the light color
aShadowAttenuationFactor	0.0f total in shadow, 1.0f completely not in shadow

Returns: the resultant color
