CC3AttenuationCoefficients Struct Reference

`#include <CC3Foundation.h>`

## Public Attributes | |

GLfloat | a |

GLfloat | b |

GLfloat | c |

The constant, linear, and quadratic coefficients of the attenuation function equation: (a + b*r + c*r*r), where r is the radial distance between a the source (light or camera) and the 3D location at which we want to calculate attenuation.

GLfloat CC3AttenuationCoefficients::a |

The constant coefficient in the attenuation function.

GLfloat CC3AttenuationCoefficients::b |

The linear coefficient in the attenuation function.

GLfloat CC3AttenuationCoefficients::c |

The quadratic coefficient in the attenuation function.
