Detailed Description

Mesh with several LOD meshes.

This mesh handle several meshes of any kind of shape (MRM, standard, coarse meshes..) At run time, it chooses what LOD meshes it must render according to its settings.

void NL3D::CMeshMultiLod::build ( CMeshMultiLodBuild & mbuild )

Build a mesh from material info, and a builded MeshGeom. WARNING: This has a side effect of deleting AnimatedMaterials.

Definition at line 50 of file mesh_multi_lod.cpp.
References _MeshVector, _StaticLod, clear, compileDistMax, and nlassert.

void NL3D::CMeshMultiLod::changeMRMDistanceSetup ( float distanceFinest,

float distanceMiddle,

float distanceCoarsest

)

Change MRM Distance setup of the Lod 0 only.
No op if the lod0 is not a CMeshMRMGeom NB: no-op if distanceFinest<0, distanceMiddle<=distanceFinest or if distanceCoarsest<=distanceMiddle.
Parameters:

distanceFinest The MRM has its max faces when dist<=distanceFinest.

distanceMiddle The MRM has 50% of its faces at dist==distanceMiddle.

distanceCoarsest The MRM has faces/Divisor (ie near 0) when dist>=distanceCoarsest.
