Advanced Member ggaliens Posted February 2, 2009 Advanced Member Report Share Posted February 2, 2009 Voxel Color Question (Hypothetical/Theoretical) How much extra memory would it require to have say a pallet of 8 colors for coloring VOXEL sculpts ??? 8 colors means 3 bits (think look-up) be voxel ??? Anyway to not store color info for every VOXEL ??? Would be so cool to have at least limited color palette to use when building and using clay. What is stored per VOXEL now ??? 1 bit ??? a byte ??? Maybe you could start off slow by allowing a color per object. That would probably frustrate folks quickly ... but if better than no color in VOX mode I think.

I think you already have that. Simply use the default shader and change the color per voxel mesh in the vox tree. Quote Link to comment Share on other sites More sharing options...
Advanced Member ggaliens Posted February 4, 2009 Author Advanced Member Report Share Posted February 4, 2009 Thanks for the news ! Color per VoxTree object will be awesome if it is there. Will try tonight. Quote Link to comment Share on other sites More sharing options...
Advanced Member ggaliens Posted February 4, 2009 Author Advanced Member Report Share Posted February 4, 2009 OK ... color per object seems fine with default shader. But why no specularity per object with defautl shader ??? I tried mucking with the specularity the same way I did color ... but it did not work. Please advise.

I tried mucking with the specularity the same way I did color ... but it did not work. Please advise. Choose other shader from VoxTree->RMB->Shader. In general I will add several new shaders soon to gain interesting effects. Quote Link to comment Share on other sites More sharing options...
Advanced Member ggaliens Posted February 5, 2009 Author Advanced Member Report Share Posted February 5, 2009 Andrew , I want to goof with Color/VOX with my kids a bit. Of course they will want color, just like me. The only problem I have with the default shader is control over specularity as I has mentioned. That being said ... I did notice that these shaders are TEXT/SCRIPT based and totally hackable. THANKS FOR THAT ! It is very nice, this Open GL Scripting Language. I took "CAR PAINT" and tried to add the CurrColor aspect to it as shown in "DEFAULT". This seemed to be straight forward for the most part. Great to hear that you will have some more shaders before too long. ** YOu should put a comment header in top of each shader file, repeating the SHADERNAME inside the file. ** Because as you know ... the filenames are all THE SAME.

Member Art4med Posted February 13, 2009 Member Report Share Posted February 13, 2009 Andrew, wondering if I can import a voxel set to work on it.... If so, what format should the file be in? Would import ever support vertex color in future... perhaps my ignorance showing here. I have been wanting to sculpt in TRULY volume space for over a decade.... and stay away from solid CAD, etc. Looking into your volume scuptor to see if it is indeed a voxel/volume approach...

Advanced Member ggaliens Posted February 13, 2009 Author Advanced Member Report Share Posted February 13, 2009 Art4Med ... Let me jump in here for Andrew so that he does nto have to toot his own horn. LOL. THIS 3DCOAT VOXELS IS GOING TO BE AWESOME FOR YOU !!!!!! Well ... it is for me. I've been having so much fun with the alpha testing. It feels so much different and works just the way you would want. It is so refreshingly different. I've always been awe inspired by ZBrush, but it is just a bit above my price point. 3DCoat might not be nearly as refined due to single developer and new product, but I think 3DCoat will be indispensible for me as an artist, even if I had ZBrush. Time will tell just how awesome it will be. I just need more shaders and some color support because I don't want to get into re-top. And I don't want to get into external rendering. I want 3DCoat to be my one-stop place for Artistic good-times ! Quote Link to comment Share on other sites More sharing options...
Member Art4med Posted February 15, 2009 Member Report Share Posted February 15, 2009 Ggaliens and Andrew, I only discovered this endeavor in the past 2 days; That said, Andrew has made some very serious software here!! On his own-- on the shoulders of giants, yes, as are we all, but especially as a single developer, this is truly a stunning accomplishment! Andrew, I see from reading the VS changelog that you are supporting PLY and STL file import. Are these formats not based on isosurfaces rather than true scalar voxel maps? I mean, I can provide an STL to import, but what I really want to do is sculpt on a DICOM data cloud. Any chance? C> My domain -=> http://Medical-illustration.com ...snipt from quote above... It is so refreshingly different. I've always been awe inspired by ZBrush........ 3DCoat might not be nearly as refined due to single developer and new product.....snip......... because I don't want to get into re-top.

Andrew Shpagin Posted February 15, 2009 Report Share Posted February 15, 2009 There is easy way - send me sample of file and remind me if I will not implement id during the month (of course if it will be relatively easy, now I have one medical format in order, raw volumetric data).

Member Crusoe Posted February 15, 2009 Member Report Share Posted February 15, 2009 http://meshlab.sourceforge.net/ You might be able to import the point cloud into MeshLab, and then export as a OBJ. Meshlab supports many 3D scanning formats. Quote Link to comment Share on other sites More sharing options...

Thanks, Andrew--- If you already have a medical format as above, your example may be DICOM, as it is the standard for medical radiologic studies. So, you may already have a set of DICOM images, but here's one source of a study (114 Mb) : http://prdownloads.sourceforge.net/osirix/...CT.zip?download Please let me know how wrong I am, but I want to model on that data set retaining the vertex colors.
