enum PositionPrecision in Tinman.Terrain.Vertices.Formats

Coordinate values are cast to 32-bit floating-point values (loosing precision in the process) and written to the vertex buffer as 32-bit floating-point values.

Remarks:

Assuming that 32-bit floating point precision is preserved in the GPU pipeline, the Float coordinate precision can be used for maps of a Size up to 8388609 (2^23+1).

Coordinate values are cast to 32-bit floating-point values and subtracted from the original values. The resulting delta values are written to the vertex buffer as 32-bit floating-point values.

Remarks:

Assuming that the GPU pipeline is capable of preserving 23-bits of floating-point mantissa precision, maps up to MaxSize can be used (when used in conjunction with Float).
