Generates a terrain chunk mesh.

Bounds  bounds,

)
private
RasterizationMesh RasterizeCollider ( Collider  col)
private

Rasterizes a collider to a mesh.

This will pass the col.transform.localToWorldMatrix to the other overload of this function.

RasterizationMesh RasterizeCollider ( Collider  col,
Matrix4x4  localToWorldMatrix 
)
private

Rasterizes a collider to a mesh assuming it's vertices should be multiplied with the matrix.

Note that the bounds of the returned ExtraMesh is based on collider.bounds. So you might want to call myExtraMesh.RecalculateBounds on the returned mesh to recalculate it if the collider.bounds would not give the correct value.
