CollisionHeightfield

class CollisionHeightfield

Bases: CollisionSolid

/*

  • CollisionHeightfield efficiently deals with collisions on uneven

  • terrain given a heightfield image. A quad tree is implemented to

  • significantly reduce the amount of triangles tested. Each quad

  • tree node represents a sub-rectangle of the heightfield image

  • and thus a box in 3D space.

Sets the number of quadtree subdivisions and modifies the quadtree accordingly. This should be called when a user wants to modify the number of quadtree subdivisions or from a constructor to initialize the quadtree.

If the number of subdivisions is too high, it will automatically be decremented.
