Function Int3PolygonClipper.ClipPolygon

int ClipPolygon (

UnsafeSpan<Int3>	vIn	Input vertices
int	n	Number of input vertices (may be less than the length of the vIn array)
UnsafeSpan<Int3>	vOut	Output vertices, needs to be large enough
int	multi	Scale factor for the input vertices
int	offset	Offset to move the input vertices with before cutting
int	axis	Axis to cut along, either x=0, y=1, z=2

)

Clips a polygon against an axis aligned half plane.

The vertices will be scaled and then offset, after that they will be cut using either the x axis, y axis or the z axis as the cutting line. The resulting vertices will be added to the vOut array in their original space (i.e before scaling and offsetting).
