Choosing a 3D processing method

In Edit mode, press 'M' to cycle through different processing methods.

Voxel and BSP processing

PathEngine supports voxel based 3D combination, as well as exact polygonal combination (with binary space partitioning).

In general, voxel based processing is much faster, whereas BSP processing results in a ground mesh that corresponds much better to the exact layout of the 3D scene.

(Refer to this page, in the 3D content processing documentation, for more details about these processing methods.)

Tile by tile processing

The demo also supports 'tile by tile' processing, where the scene is split up into a set of horizontal tiles that can then be processed independently.

In this case, and at this scale, the overhead of splitting the tiles and recombining outweighs the benefits, but tile by tile processing is an important feature when you need to work with very large worlds.
