A procedurally generated mesh creates a new track for each game. Right now the road will always draw linearly along the z-axis, with random values along a certain range for the x-axis.

This mesh works pretty well for straight bits of road, but sometimes in more jagged areas mesh triangles will draw on the wrong side of the axis resulting in holes.

Early iterations of the mesh had much worse success drawing a road without holes, caused by incorrectly calculating the edge of the road to the left of the generated path

Road generated with no relationship between points' x-axis location:
