Lights.
Library: xviews or winviews or mviews (mutually exclusive)
This class is the base class of lights. It allows you to model a light source to use in IlvDiffuseLightingFilter or IlvSpecularLightingFilter.
Every light has a color.
IlvDiffuseLightingFilter, IlvSpecularLightingFilter, IlvDistantLightSource, IlvPointLightSource, IlvSpotLightSource Constructor.
Initializes a new instance of the class IlvLightSource.
The default light color is white.

virtual |
Destructor.
The destructor releases all the memory used by the instance.
| IlFloat IlvLightSource::getB | ( | ) | const |
Returns the blue component value.
| IlFloat IlvLightSource::getG | ( | ) | const |
Returns the green component value.
|
virtual |
Returns the vector from this instance to a given point in 3D space.
| x | The x position of the point. |
| y | The y position of the point. |
| z | The z position of the point. |
| result | An array of 3 floating point values that will hold the vector. |
Reimplemented in IlvSpotLight, IlvPointLight, and IlvDistantLight.
| IlFloat IlvLightSource::getR | ( | ) | const |
Returns the red component value.
| void IlvLightSource::setB | ( | IlFloat | b | ) |
Sets the blue component value.
| b | The new blue component value. |
| void IlvLightSource::setG | ( | IlFloat | g | ) |
Sets the green component value.
| g | The new green component value. |
| void IlvLightSource::setR | ( | IlFloat | r | ) |
Sets the red component value.
| r | The new red component value. |
