Surface Measurements

3D Measurements > Surface Measurements

Surface Measurements allow you to make measurements from the currently rendered surface(s).

*Surface measurements can take some time depending on the resolution and feature density of your rendered surface(s). It is recommended that you render your surface with 50% or more simplification prior to taking surface measurements. Enter the desired simplification percentage in the “Simp” box in the Render Panel prior to generating your surface.

• Positions: Measures the X, Y, Z coordinates of each point on the surface

• Curvatures: Measures the local radius curvature (in um) at each point on the surface [1]. The averaging radius controls the extent (in um) to which the surface positions are averaged prior to the local curvature calculation.

• Thicknesses: Measures at each point on the surface, the distance to the other side along that point’s local normal

• Normals: Measures the local normal at each point on the surface
