BuildMeshLOD

BuildMeshLOD()

Syntax

BuildMeshLOD(#Mesh [, NbLOD, Distance.f, ReductionValue.f])

Description

Build automatically one or several level of detail (LOD) for the mesh. The #Mesh will be replaced automatically with less complex mesh when displayed above the specified distance from the camera. If more precise LOD meshes are required, AddMeshManualLOD() can be used.

Parameters

Mesh The mesh to use.

NbLOD (optional) Number of needed LOD for this mesh. If this parameter isn't used, then the LODs will be automatically calculated.

Distance (optional) The minimum distance from the camera where the first LOD mesh will be used instead of #Mesh. For the next LOD meshs, the distance will be calculated using this formula: 'Distance / SqrF(1-ReductionValue)'.

ReductionValue (optional) The reduction to apply, between 0 (no reduction) and 1 (100% reduction).

Example: CreateMeshLodLevels(#Mesh, 3, 100, 0.75)
- The first reduction of the original mesh starts from 100 units of the camera, vertices number halved by 4 (75% reduction). - The second reduction of the original mesh starts from 200 units of the camera, vertices number halved by 16. - The third reduction of the original mesh starts from 400 units of the camera, vertices number halved by 64.

Return value

None.
