Grid: Rendering Model

Rendering Model

The basic world model for source is a x,y coordinate on a flat (infinite) 2 dimensional plane. Each tile is 1 unit high and wide. The center of the tile is at an integer coordinate. Hence the edges of the coordinates are at the half value.

X coordinates give the dimension to east or west. Y gives coordinates to the north and south.

Z gives an altitude (or height). By default the grid is a height 0.
