Hi Manik, As the work was almost done in the previous messages, I put the code in a new command (AimsMeshes2Graph as I said just before) that will be available in the next version of Aims. I know that you won't wait, so here is the source (this one has been tested and works): /* * Copyright (C) 2004...

Hi Manik, You're right, my program was wrong. The rc_ptr<> is a reference counting pointer. It's normal you get a segfault in your example program, because there you build a rc_ptr on an object locally allocated. rc_ptr takes ownership of the object (here a mesh) and destroys it when no rc_ptr point...

Sorry, this turns out to be a very technical developers topic... The hierarchy format is rather simple, you will understand it by looking at one example. The graph format is also simple in appearance, but as it can hold many different things under different shapes, it has become quite complex. The t...

Hi, If you want to make a structured set of objects with consistent colors on many subjects, the graph solution is certainly the best, althrough building the graph itself may cause you some headaches. For episodic work or testing purpose, the idea of providing a default color in the .minf header is ...

Hi Nicolas, I've worked in Anatomist, and I have made a new texturing mode which uses color interpolation in RGB space (rather than the normal palette space): http://brainvisa.info/forum_images/texturing_palette_interpol.png http://brainvisa.info/forum_images/texturing_rgb_interpol.png left: palette...

OK I think I understand now, you want to make a 3D representation of the axis itself. We don't handle meshes with mixed polygons (anyway, OpenGL does not either), you have to chose at the beginning: triangles, squares... Polygons with 2 points are segments: so do you want to only display a line ? Th...

Oh yes you're right, AimsMesh is a low-level command that generates multiple mesh files (one for each interface of the objects to mesh) and generates file names with numbers without bothering about the extension. This should be fixed anyway. Well, right now you have three options: - use AimsMeshBrai...

Hi Tristan, Well, I think the doc of AimsMesh is outdated... I'll fix it. The --tri option certainly doesn't exist anymore (I haven't checked yet) because it's not needed anymore, you just have to specify .tri extension (rather than .mesh) to the output file argument: AimsMesh -i toto.ima -o toto.tr...

Yes it is possible, but not directly:
- create each individual mesh file with AimsMeshGenerate
- concatenate them using AimsZCat:

- create each individual mesh file with AimsMeshGenerate

Code: Select all

Hi Nicolas, I fixed your first problem: unnormalized textures can now be exported frol 3D fusions. But of course it's done in the development branch of anatomist, which will not be avialable for a little while... But now you know one of your problems will have a solution one day... I haven't done an...
