|---|---|
| BresenhamTerrainPicker |
It basically works by casting a pick ray
against the bounding volumes of the TerrainQuad and its children, gathering
all of the TerrainPatches hit (in distance order.) The triangles of each patch
are then tested using the BresenhamYUpGridTracer to determine which triangles
to test and in what order.
|
| BresenhamYUpGridTracer |
Works on the XZ plane, with positive Y as up.
|
| TerrainPickData |
Pick result on a terrain patch with the intersection on the bounding box
of that terrain patch.
