Hi
Is there a way I can generate an endocast from an STL file?
The cavity I want to use for generating the endocast has external openings.
Any help would be highly appreciated!
TIA
You can, but results may not be ideal.
You can convert your stl to a segmentation, and then use the WrapSurfaceSolidfy extension to fill the cavity. But sometimes conversion has artifacts that interfere with getting a good result, hence it is better practice to create the endocast from the original volume that the model was derived from.
Endomaker in R Studio works directly on the 3D meshes, in .STL, .PLY, or .OBJ format: R: endomaker.
For a segmentation in Slicer, there is the SegmentEndocast function, but this may be picking up more than just the intracranial volume, such as aspects of the brainstem and orbit.
Thank you @muratmaga. I’ll look into this method!
Thank you @ThomasVanParys. Unfortunately I have no experience using R…
Hi! I saw your question and actually created a kit that solves exactly this problem using 3D Slicer.
It includes a sample cavity STL, a ready-made endocast, and a step-by-step workflow using the Segment Editor + Smoothing/Logical Operators.
Here’s the kit if you’re still working on this: STL Endocast Generation Kit – 3D Slicer Workflow for Open Cavity Models
Happy to help if you run into issues!
