light_ies #21

Open StefanH-AT opened 4 years ago

StefanH-AT commented 4 years ago

Add entity light_ies that allows to place a light with custom ray cast behavior by selecting an IES texture

Gocnak commented 3 years ago

Can there be more info here, what is meant/desired in terms of "IES texture"s?

VortexParadox commented 3 years ago

IES files determine how a light is cast onto the world. Another similar term used inside realtime 3D is gobo lights (although they are not the same, functionally the confusion is understandable), which is already present in Source, the light texture of an env_projected_texture. Think of having the physical light fixture, without the need of calculating how a light will refract and bounce in and out the fixture. More info and examples
