Nine
Eleven types of RedSDK luminances are provided you can create and edit any of the following using the Render manager.
...
- Power – Sets the power of the light in Watts.
- Luminous Efficiency – Sets the luminous efficiency of the light in percentage (%).
- Intensity decay – Set the rate at which the lights power diminishes.
- Color – Sets the color of the light.
- Color Temperature – Alternate color value which supports definition of the color by temperature in Kelvin.
- Color Affect – Sets the relative intensity (power) of the color light.
- Samples Count – Sets the maximum number of light samples.
- Pos – Sets the X,Y,Z position of the light relative to the object to which it is attached.
- Dir – Sets the X,Y,Z direction of the light relative to the position.
- Top – Defines a second axis which is perpendicular to the direction, used for the rotation, if the lights display is not circular.
- Samples Count – Sets the number of samples used to populate the light surface. Must be greater than 0
- Width – Sets the width of the defining rectangle.
- Height – Sets the height of the defining rectangle.
- Shadows – Sets whether the light will generate shadows, or not.
- Shadow Color – Specifies the color of shadows created by the light.
- Texture File Name – Rather than using a single constant color for the whole light, you can setup a texture from which light color will be read. Using a texture, you can simulate projectors or complex light filters.
- IES File Name – Manufacturers measure the behavior of their bulbs and store their directional contribution into IES files. Those files are available for most of the bulb models directly from the manufacturers' web sites. Even if IES files store information about the shape of the emitter, they are not used here.
- Caustics – Specifies whether the light will generate caustic effects.
- Visible Geometry - Specifies whether the physical geometry of the associate 3D objects will be seen.
- GI Baked – Supports GI baking.
- Enlighten volume – Enable the light to illuminate with Volumetric effects
Spherical Physical Light
- Luminous Efficiency – luminous efficiency of the light in percentage (%).
- Intensity decay – Set the rate at which the lights power diminishes.
- Color – Sets the color of the light.
- Color Temperature – Alternate color value which supports definition of the color by temperature in Kelvin.
- Samples Count – Sets the maximum number of light samples.
- Pos – Sets the X,Y,Z position of the light relative to the object to which it is attached.
- Dir – Sets the X,Y,Z direction of the light relative to the position.
- Spot Angle – the spot half-angle. In the cone whose apex is at the light's source position, headed at Dir, of Spot angle , the light radial intensity is pow(cos(angle(L,S)),Radial intensity decay).
- Shadows – Sets whether the light will generate shadows, or not.
- Shadow Color – Specifies the color of shadows created by the light.
- Shadow Map – Shadow maps are generated by testing whether or not each specific pixel is visible from the light source. This accomplished by comparing each pixel to a depth image (z-buffer) of the light source's view, stored in the form of a texture file. Shadow maps can accelerate the rendering of shadows, but usually as the cost of some quality.
- Texture File Name – Rather than using a single constant color for the whole light, you can setup a texture from which light color will be read. Using a texture, you can simulate projectors or complex light filters.
- IES File Name – Manufacturers measure the behavior of their bulbs and store their directional contribution into IES files. Those files are available for most of the bulb models directly from the manufacturers' web sites. Even if IES files store information about the shape of the emitter, they are not used here.
- Caustics – Specifies whether the light will generate caustic effects.
- Visible Geometry - Specifies whether the physical geometry of the associate 3D objects will be seen.
- GI Baked – Supports GI baking.
- Enlighten volume – Enable the light to illuminatewith Volumetric effects
Sky Light
This physical skylight shape generates a light source that casts light from a dome surrounding the scene. In addition a skylight shape can create a physical sky texture that can be used in the rendering for direct visibility. A physical skylight shape is rendered on the CPU and is rendered by a sampled skydome on the GPU. The GPU rendering of the skylight is a good approximation of the real physical skylight rendered on the CPU.
