Resource: image3DLight Basic v0.1.4
Author: Ren712

This resource adds an ability to create simple light sources.
The purpose of this resource is to give an efficient alternative to
dynamic lighting resource and prepare for new deferred rendering
approach. Instead of applying shaders to world textures, I have decided
to recreate needed information from scene depth to apply effect post world
(drawn on transformed and tessellated image2material3D).
You can add virtually limitless number of lights. In order to work the effects
require shader model 3 GFX with readable depth buffer support.

CImgLightDirectional - Creates a global directional light
CImgLightPoint - Creates a point light.
CImgLightPointNoNRM - Same as above but no normal shading
CImgLightSpot - Creates a spot light.
CImgLightSpotNoNRM - Same as above but no normal shading
CImgLightSpecular - Creates a specular light.
CImgLightDark - Creates an inverted color point light
CImgLightDarkNoNRM - Same as above but no normal shading
CImgTexture - Creates a 2D quad
CImgTextureNoDB - Creates a 2D quad (basic method)
CImgTextureProj - Creates a projected 2D texture
CImgTextureProj2 - Creates a projected 2D texture type2
CImgTextureProjNoDB - Creates a projected 2D texture (basic method)
CImgTextureProjNoNRM - Same as above but no normal shading
CImgTextureProjCone - Creates a projected 2D texture (perspective projection)
CImgTextureProjCone2 - Creates a projected 2D texture type2(perspective projection)
CImgTextureProjConeNoDB - Creates a projected 2D texture (basic method)
CImgTextureProjConeNoNRM - Same as above but no normal shading
CImgTextureProjCube - Creates a projected cube texture
CImgTextureProjCubeNoNRM - Creates a projected cube texture

Shader model 3.0 GFX, readable depth buffer in PS access.

test.lua lets you create lights in front of the camera view.
