Create Polygon Model does smooth
Closed, ResolvedPublic

Description

Create a segmentation and a corresponding polygon model (right click "create polygon model"). The polygon model is slightly different compared to the segmentation image. As a consequence, information is lost when you convert this surface back to a binary image via "Surface Masking" of the segmentation utilities view.

This could be a 0.5 offset.

Segmenation example

This bug will cause a loss of detail if you create a polygon model of the attached segmentation and convert this model back to a segmentation with the utilities.

marching cube filter threshold changed

The marching cube filter threshold was incorrect. We changed the value to 0.5 instead of 1.
