I need jit.gl.mesh to show exacly the same the shapes generated by jit.gl.isosurf. (because I want to draw this shapes as points, or lines, etc..).

The problem is that when I connect mesh to isosourf, mesh is showing different content than isosurf. While the shape desapears in isosurf, mesh is still showing content, and this content remains forever. (It's like an ''erase'' function or something similar is missing to mesh). Could someone look at the patch and help, please ?

How can I fix this patch in order that mesh show exacly the same shapes than isosurf?

This is a jitter example contained in the max package, I just added a mesh object connected to a isosourf.

i've noticed this problem in the past, and your post inspired me to take a look. isosurf contains an internal state variable indicating the number of triangles to draw from its vertex cache, based on its attributes. if we have user access to that variable, we can use that to control the dimension of a jit.submatrix prior to sending to the gl.mesh, which will give us expected results with matrixoutput.

i've attached an update jit.gl.isosurf external (Mac only) that provides access to this variable as a read-only attribute (trianglecount). i've also updated your patch to demonstrate how to use this with jit.submatrix. give this a look and let me know if it works for you as expected.

go to Contents/Resources/C74/externals/jitter/

replace the updated jit.gl.isosurf.mxo in that folder

for 64 bit drag into C:\Program Files\Cycling '74\Max 7\resources\externals\jitter

for 32 bit drag into C:\Program Files (x86)\Cycling '74\Max 7\resources\externals\jitter

Thank you for your quick answer, I appreciate it and the community I'm sure will so.

Is it possible to have this jit.gl.isosurf version for Windows , please?

I am a Windows 10 user when I'm using jitter ,

(only way to use a NVIDIA Gtx 1080 GPU in a laptop).

ok, i've updated the above post with the windows externals. let me know how it goes.

Thank you for this new version of jit.gl.isosurf in both OS and that example patch, it's

I tried it in Windows 10, and in my old Mac. The big extra content that .isosurf transmited to mesh is gone, it looks so much better, nevertheless, there is still diferences between the content showed by .isosurf and the content showed by .mesh. When you set mesh attribute draw_mode to "lines" and the density of the volume is high, you can see lines interconecting "empty"spaces.

This is so clear in this example, I took the Jitter recepicy 04.AsteroidGrowth made by Andrew and I added part of the example patch you just added in this topic. You'll see lines connecting the "asteroids".

When mesh attribute" draw_mode" is set to points, and "point_size"is set to 10, you will see a point that never ever desapears, even if the audio signal is set off.

Question : Is there any setting , message to send or something I can do in order to make .isosurf and .mesh to show exacly the same? If not, do you think this could be fixed?

please study the patch i posted above to understand how you use the new trianglecount attribute with jit.submatrix to get expected results with jit.gl.isosurf matrixoutput

Thanks , it works perfectly, (the problem was that .isosurf mode attribute needs to be set in "tetra", I had it in "cubes").

Is there any possibility that this new version of jit.gl.isosurf will be incorporated into a future release of Max, or are we going to have to manually install this new version each time you release an update?
