Detailed Description

+A block of vegetable instance groups. +

+CVegetableSortBlock are sorted in Z order. NB: for speed and convenience, only the RdrPass NL3D_VEGETABLE_RDRPASS_UNLIT_2SIDED_ZSORT is sorted. A block have a number of quadrants (8). Each quadrant has an array of triangles to render. Internal to VegetableManager. Just an Handle for public.

+if !Dirty, updateSortBlock() is a no-op. /see CVegetableManager::addInstance() CVegetableManager::deleteIg() Warning! Use OptFastFloor()! So call must be enclosed with a OptFastFloorBegin()/OptFastFloorEnd(). +
