Detailed Description

Provides high level information related to a dtMeshTile object.

Member Data Documentation

bvQuantFactor

float dtMeshHeader::bvQuantFactor

The bounding volume quantization factor.

This value is used for converting between world and bounding volume coordinates. For example:

const float cs = 1.0f / tile->header->bvQuantFactor;
const dtBVNode* n = &tile->bvTree[i];
if (n->i >= 0)
{
    // This is a leaf node.
    float worldMinX = tile->header->bmin[0] + n->bmin[0]*cs;
    float worldMinY = tile->header->bmin[0] + n->bmin[1]*cs;
    // Etc...
}
