Thanks for sharing this, I would love to get one of my pieces done in 3D Print.

You are most welcome, and that is on my list of things I want to do along with Animating fractals 
All in good time

Very interesting. The first mesh in Meshlab looks printable. What happens when you check it in Netfabb? Why do you have to go through the volumetric render?
Thanks!

Hello. The first mesh you can see in Meshlab is generated with Geometrica and it is not printable, when you try to repair errors with Netfabb the mesh simply vanish, disepear.
It is due to the way Geometrica is working. Maybe in the future it will be possible if Aexion fix this problem.  Volumetric render also permit to create solid walls into your mesh.
Cheers, Nic

OK, thanks for your answer. this method looks promising to get optimized meshes without marching cubes / volumetric...What Incendia tutorial would you recommend to get started? I did some tests, and I saw many formulas that looks very different once in Geometrica. I feel it's much less predictable than M3D voxels but I probably need to better understand how this works and get more familiar with Incendia in general. Cheers!

The difference of view between Incendia and Geometrica are explained here " By default Geometrica will show the Baseshape preview, since the main objetive of the program is to works with the baseshape resolution. When a fractal model is too large, the program automatically return to this preview type." source IncendiaWiki

Hi Nic,
I read this material and tried the given examples, but when I start a new param from scratch in Incendia, export as .igm and import into Geometrica, sometimes it looks totally different, like if there was a bug. Are there any rules or prerequisites in Incendia to make sure the fractal will look the same in Geometrica?
Thanks again for you precious help! This is fun to try new programs
Cheers

Generating 3D model is really something very complex, with Geometrica Aexion made a big work, but it is some case where it is just impossible to do a good model. You may discover with Incendia what it is possible and what it is not possible to export, i try many many times before to achieve a good mesh.  I suggest you to start with simple shapes at the begening

I definitely appreciate the work done in Geometrica. Even with the need for trial and error, this is a big step forward because I think the meshes produced by Geometrica can be fixed to be 3D printable with some tweaking, without having to go convert to voxels. The mesh is much closer to the real fractal than a "3D scan" of it. That saves a large number of triangles and gives a more detailed final result.

I try more than 100 times to fix meshes generated with Geometrica, all the times the Netfabb testing failled. The polygones generated by geometrica are not attached, you must absolutly use meshlab to join the close vertices, but that create a lot of errors into the structure of the mesh and a lot of faces are inverted by this way. The author of the software know well this problem and he is working to ameliorate the files output of his software.

I got a clean and printable mesh after a few tests. But I don't remember which filters I used in Meshlab. Maybe I was too lucky! especially regarding the inverted faces problem which happens all the times. Hopefully Aexion will find how to fix it.

Parfait, si tu pouvais me faire parvenir image de ton mesh imprimable je pourait me faire une idée de la complexitée de ton model, je suis très curieux de voir a quoi il resemble.
 Je ne dit pas qu'il est impossible de générer des mesh imprimable avec Géometrica mais je constate que dans mes expérimentation j'ai rencontré beaucoup trop d'erreurs dans les mesh et qu'il était impossible de les corriger. Ton expérience avec géométrica m'interesse beaucoup car s'il était possible de pouvoir utiliser les models directement générer par géometrica se serait extra. Tien moi au courant, merci

J'ai parlé trop vite. Le mesh (avec une formule Hyperbolic Tesselation) a l'air clean dans Netfabb (pas de warning rouge) mais il y a des faces inversées un peu partout, et une fois uploadé sur Shapeways, il manque plein de petits bouts. Je pense qu'il faut faire plus de tests dans cette direction très prometteuse, peut-être en utilisant des filtres comme "Uniform Mesh resampling" ou "Surface reconstruction : Poisson". Je te tiens au courant dès que j'ai le temps de m'y remettre.

J'ai relu la documentation de Shapeways au sujet des impression 3D incluant de multiple "shell" , ils disent que ca ne posse pas de probleme, Netfabb par default cherche a ne créer que 1 seul "shell" d'ou les erreurs avec Geometrica, j'ai peu être trouver la solution . Il faut enlever les "self-intersection" uniquement et corriger les "flipped-triangles" avec Netfabb mais ne pas faire automatic repair.

Regarde ce model Geometrica à marcher, shapeways l'a accepté  sta.sh/01gtsnrbpn80
C'est une bonne nouvelle, je vais faire d'autre essais

Enlever les "self-intersections" n'est disponible que la version pro de Nettfab. Tu l'as acheté ?
Cela dit, même en inversant les "negative shells", il rest le problème des faces internes. Cela se corrige assez facilement en suivant ce tutorial: meshlabstuff.blogspot.de/2009/…
Enjoy!!

Nous avons fait le même test en même temps!!!!! J'ai aussi trouvé comment faire pour le pb de faces inversées avec Netfabb:
Repair > Actions > Select Shells with negative volume
et ensuite cliquer sur le bouton "Flip selected triangles" dans la barre d'outils.
Victoire!!!! Je vais être obligé de me mettre sérieusement à Incendia Merci!!!

Super, c'est cool, bravo. J'ai aussi uploadé 2 models sur Shapeways. Merci pour les infos et le lien que tu m'as envoyer. Je vais travailler tout cela.

Maintenant que nous avons trouvé comment éviter la conversion en voxels, j'ai l'impression d'avoir un nouveau monde à explorer avec Incendia. Je regrette de n'avoir jamais vraiment mis les doigts dedans, car cela a l'air très puissant, surtout les transformation "blocks". Mais la logique est tellement différente de Mandelbulb3D que cela va me prendre beaucoup de temps avant t'atteindre ton niveau...

Je suis bein d'accord, Incendia est un monde à part, cela fait deux ans que je m'accroche a ce programme et je n'ai pas encore fait le tour. Je me réjouis de voir ce que tu vas faire avec
