Constant transvoxel_data::transition_cell_data::TRANSITION_VERTEX_DATA

pub const TRANSITION_VERTEX_DATA: [[u16; 12]; 512];

Gives the vertex locations for every one of the 512 possible cases in the Transvoxel algorithm.

Each 16-bit value also provides information about whether a vertex can be reused from a neighboring cell. The low byte contains the indices for the two endpoints of the edge on which the vertex lies. The high byte contains the vertex reuse data.
