What would be the path to scan a 3D object then get a model to import into [jit.gl.model], for instance?

Hi,
I've never used the Structure Sensor (http://structure.io). Would anyone have some experience?

Thanks for any pointer!

Also, same question with the Sense Scanner (

I don't have experience with the mentioned tools, I use 123D Catch which is a great free app and works very well.

2. Import it into some mesh editing software (I use Meshmixer, also free) to fix the scanning errors or to modify/prepare your 3D object in desired way

If you want to process the geometry you might want to reduce all unwanted multiplications of the vertices - in average jit.gl.model spits out approximately 6 times more vertices as necessary. To do that you can use my external that you can find in this thread: 

https://cycling74.com/forums/share-eliminate-redundant-replicated-vertices-with-jit-gl-model-gl-multiple

 (look for THINANDINDEXFORTRIANGULARMESH.ZIP). However that external unfortunately outputs only geometry planes and index matrix for jit.gl.mesh in order to draw triangles correctly when using the reduced geometry. In case you are happy with that your next steps would be:

7. When you want to load your 3D object simply import it in a matrix instead of jit.gl.model

1. Make a 3D model
2. Import it into some mesh editing software (I use Meshmixer, also free) to fix the scanning errors or to modify/prepare your 3D object in desired way
3. Export an obj file
4. Import obj file into jit.gl.model

5. Eliminate redundant vertices
6. Save your geometry and index matrix

Thanks for those tips. Was going to check out 123D Catch, but Autodesk pulled it. If you have it installed, make sure you keep it!

And thanks for the Meshmixer reference: they didn't pull this one out, it's nice.

I didn't use this 3d scanner, I used handheld 3d scanner, but I think is quite the same..
You can search lot's videos on youtube.


just reading this post JeanFrançois, almost my whole 

 project is based on it, if you had question, let me know here. Using also depthkit software with kinect for it.
