Some of the 3d images though look quite rough in meshlab, even if I select the textured obj file from meshroom, for this reason I looked around and stumbled on Meshmixer. Meshlab to then use the shaders menu to create the depthmap.

Ok, I simply want to make greyscale depthmaps to cut on my router.

I don’t know at this point if I need the CT volume to match the 3D models, but for these cases it would be nice to have the full workflow in Slicer.Complete novice at work here. I know I can use Split Volumes in the Segment Editor to create separate volumes for each segment but can I then move these to the correct anatomical positions and then create a new CT volume? I can move the exported models in Meshlab, but then the CT volume doesn’t match. I have recently started working with post-autopsy CT scans so the areas of interest are not in the correct places.

And I really use a combination of Slicer, Meshlab, and Meshmixer for surface scans and CT/microCT models, depending on what I need! For the microCT models, I have started using the Surface Toolbox more than Meshlab to decimate. I have my workflows down for Meshlab, so it’s just a matter of sitting down with Slicer to see if I can do the same things. The ICP alignment using 4 or more points is quick and sometimes works for articulating matching edges on fragments or sutures.

I also apply Ambient Occlusion shading for pathological CT/microCT specimens to highlight the surface details and use the same function to remove internal surfaces if needed.Įven compared to Meshmixer, the manual alignment in Meshlab is easier for me–I can select a single axis to translate/rotate or just click on the model and move it (I usually need this to align separate pieces or 2 surfaces of a flat object). I can quickly toggle vertex colors or textures on/off and transfer them between meshes. I use Meshlab to make final meshes from my surface scans–deleting unwanted parts via surface painting or drawing boxes, aligning scans or parts, flip normals, Poisson surface reconstruction for a watertight mesh, decimation, smoothing, adding color/shading. If you let us know what surface manipulation features you need (especially those that are often used along with imaging) then we can take that information into account when deciding what features to prioritize. You can show the current 3D view in virtual reality in Slicer by a single button click. If anyone needs to frequently put together models from multiple pieces, investing $1000 into a virtual reality setup is absolutely worth it (you also need to get a desktop computer or a gaming laptop, because most laptops do not support virtual reality). You can also rotate and zoom the world around very easily, so you are not limited by your physical eyesight or steadiness of your hand.

It is very similar to holding the physical pieces and putting them together with your hand, but it is actually easier, because the pieces stay in mid-air where you left them, so you don’t need glue. You would need funding or research groups that are interested in making their automatic alignment tools available for Slicer.įor manual alignment, virtual reality works amazingly well. There have been modules developed for automatic bone segment registration, but the developers have moved on. Loading textures from separate image files would be quite easy to implement, too. Displaying RGB color when loading PLY textures should have improved usability already.
