Surfaces Tab

The Surfaces tab offers surface operations and is only available with the VOXEL math tool.

Button	Syntax	Definition
	.intersect	Returns true (1) where voxel cells intersects surface or grid, and false (0) otherwise.
	.inside	Returns true (1) where voxel cell centers are inside a closed surface, and (0) otherwise.
	.side	Returns 1 where voxel cell centers are 'above' an open surface or grid, 0 if they "intersect" the surface, and -1 if they are 'below' the surface. The outcome is set to DUMMY if the side cannot be determined. For those voxel cells that do not lie inside the volume normal to the finite surface and bound by the edges of the surface, the surface cannot be determined. Above and below are determined by the general orientation of the triangles joining surface points
	.dist	Returns the closest distance of voxel cell centers to a surface or grid, along the normal to the surface.
	.insidedist	Signed closest distance of voxel cell centers to a closed surface. Positive 'inside' and negative 'outside'.
	.sidedist	Signed closest distance of voxel cell centers to an open surface or grid. Positive 'above' and negative 'below'.

Tooltips that include an argument and short descriptive name are provided for each tab item.
