Surfaces Tab

The Surfaces tab tab provides access to surface operations and is only available when using the Voxel Math tool.

Each tab item includes a tooltip that shows the required arguments and a brief description of the function.

Button	Syntax	Definition
	.intersect	Returns true (1) if voxel cells intersect a surface or grid; otherwise false (0).
	.inside	Returns true (1) if voxel cell centers are inside a closed surface; otherwise false (0) .
	.side	Determines the relative position of voxel cell centers to an open surface or grid: 1 if they are 'above' the surface 0 if they 'intersect' the surface -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 inferred based on 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	Returns the signed closest distance of voxel cell centers to a closed surface: Positive = 'inside' Negative = 'outside'.
	.sidedist	Returns the signed closest distance of voxel cell centers to an open surface or grid. Positive = 'above' Negative = 'below'.
