class Enlighten::InputLightFalloffTable
Class encapsulating the description of a light falloff curve.
The Input Light Falloff Table stores the falloff model used by a pointlight or spotlight. The falloff of the light is represented between the m_Radius and m_CutOff distance stored in an InputLight.
Up to m_Radius distance, the light falloff is required to have a value of 1.0. Beyond m_CutOff distance, the light falloff is required to have a value of 0.0.
Indexing is performed with the following equation:
d = Max(0, distance - m_Radius) / (m_CutOff - m_Radius) index = (g_SampleCount - 1) / (1 + d * d * (g_SampleCount - 2))
Variables
| Name | Description |
|---|---|
| const Geo::s32 g_SampleCount = 16 | The number of samples stored in this table. |
| const float g_TableSampleIndices[g_SampleCount] | g_TableSampleIndices stores a set of indices that can be used to generate a LightTable. |
| float m_Table[g_SampleCount] | m_Table Stores the input light falloff table samples. |
Functions
| Name | Description |
|---|---|
| InputLightFalloffTable() | Default constructor. The table values are set to a simple default inverse squared falloff. |
