Member Function Documentation
| virtual void iLODControl::GetLOD | ( | iSharedVariable *& | varm, | |
| iSharedVariable *& | vara | |||
| ) | const [pure virtual] |
Return the variables used by lod.
If lod was not set using variables then varm and vara will be set to 0.
| virtual void iLODControl::GetLOD | ( | float & | m, | |
| float & | a | |||
| ) | const [pure virtual] |
Get the current LOD function.
| virtual int iLODControl::GetLODPolygonCount | ( | float | lod | ) | const [pure virtual] |
Get a rough estimate of the number of polygons for a given LOD value (between 0 and 1, similar to the value used by SetLOD()).
Note that a mesh object that doesn't support LOD should always return the same number of polygons.
| virtual void iLODControl::SetLOD | ( | iSharedVariable * | varm, | |
| iSharedVariable * | vara | |||
| ) | [pure virtual] |
Set LOD using variables.
| virtual void iLODControl::SetLOD | ( | float | m, | |
| float | a | |||
| ) | [pure virtual] |
Set a parameters for a function to compute LOD for the given LOD control.
The function is as follows:
float lod = m * distance + a;
The result of this function will be capped to the [0,1] range with 0 meaning worst quality possible (highest speed) and 1 highest quality.
