farsthary Posted January 25, 2011 Report Share Posted January 25, 2011 Hi all well, I can't foretell what would be the needed changes but I would like to clarify some things: Dynamic Subdivision can (and will) work with Surface mode as well with voxel mode, in theory both, voxels and polygons can have dynamic adaptive subdivision, though the final implementation may differ because both have radically different algorithm ... currently Unlimited Clay work on polygons so is starigthfoward to first target the Surface mode but at the same time if we allow voxels have sub-voxels (further refined like a tree) then the Voxel mode can easily handle adaptive refinement and the output from Surface dynamic subdivision will be easily tackled, I have high hopes in the voxel mode too because voxel refinement will allow implicit dynamic subdivision surface reconstruction at no aditional cost and combined that with the current arsenal of features that 3DC currently boost ... well, WOW Also, dynamic subdivision is just the top of the iceberg the beauty of UC is that it aims at mixing mesh/voxel operators and sculpting, that way in the future, could be easily extended to allow dynamic reduction (decimation) among other things Cheers Farsthary Quote Link to comment Share on other sites More sharing options...
Applink Developer haikalle Posted January 25, 2011 Applink Developer Report Share Posted January 25, 2011 WOW indeed... It looks like that you have a strong vision, and I like it! Excited to see what future brings ahead. Having dynamic voxels and polygons would be dream come true. But understand that it can take time to make it work. So having surface mode as a first target sounds great. Quote Link to comment Share on other sites More sharing options...
Psmith Posted January 25, 2011 Report Share Posted January 25, 2011 Raul: Do you think that it will be possible to make "Surface Mode" more of a permanent Room - in the sense that true polygon sculpting, (as found in "Brand X"), can take place there? Will it be possible to export directly from this "Mode" or "Room" or to "Merge" the results into the Paint Room - without sending the results back through the Voxel Room? If so, this can simply be named the "Poly Room", giving it a permanent spot in the interface and it could and should contain all polygon sculpting tools. As it is now, it is just a temporary "zone" to speed up Voxel Sculpting. Its seems to me that Dynamic Subdivision (for polygons) coupled with true polygon sculpting is the fastest possible workflow. Subdividing voxels (on the fly) will still be very resource hungry. Greg Smith Quote Link to comment Share on other sites More sharing options...
Advanced Member Tom K Posted January 25, 2011 Author Advanced Member Report Share Posted January 25, 2011 well, I can't foretell what would be the needed changes but I would like to clarify some things: Dynamic Subdivision can (and will) work with Surface mode as well with voxel mode, in theory both, voxels and polygons can have dynamic adaptive subdivision, though the final implementation may differ because both have radically different algorithm I was wondering about this! This seems to suggest to me that only the voxels exposed to the surface of the object would need to be subdivided and the ones inside the volume could be big. A bunch of giant voxel cubes surrounded by increasingly smaller cubes. So if we started sculpting on a voxel cube it could actually be just a single voxel until we started adding detail?

Advanced Member spacepainter Posted January 25, 2011 Advanced Member Report Share Posted January 25, 2011 http://farsthary.wordpress.com/2011/01/25/spin-my-particles/ And fluid voxels!!! Farsthary, coding your dreams... hahahaha! PS people please donate to http://www.incendia.net/ maker of 3d fractal software, very good stuff.

Reputable Contributor AbnRanger Posted January 26, 2011 Reputable Contributor Report Share Posted January 26, 2011 I agree with Greg and TomK on their points. But I think before you go to far down this trail, I would ask about the prospect of removing the triangular mesh representation in Voxel/Volume mode. That has to be one of the main bottlenecks in voxel sculpting performance. For every single brushstroke, 3DC has to calculate the volume (voxels on or off) AND resample the mesh that contains the volume. Since you have some experience with particles as well, why not use SHADING to visually represent Voxel volume? I would think newer CPU's and Graphic cards could chew right through it with relative ease. Each Voxel in a grid is treated as a solid Volumetric Particle. Each Voxel Particle would have Color (no more than 8bit), depth (location ID), and Opacity (on or off, 100/0) information. Upon export or merge (to the other rooms), a triangular or quad mesh could then be applied as it is now. In 3ds Max's Volumetric FX plugin, Afterburn, you have a mode called "Hypersolids" that appear similar to what this would look like. One major benefit to using just a shaded Voxel platform, would be the ability to apply true 3D patterns/fractal algorithm's, such as wood...rock, masonry, etc. But I think performance is where the major benefit will be. We've been waiting on CUDA to be optimized for the Voxel room. Shaded Voxels (no outer mesh), could eliminate the need for CUDA as well, perhaps. You can see Hypersolids talked about at the 5:20 mark: http://www.youtube.com/watch?v=YBbuYWgR7ME Another video using Hypersolids: http://www.youtube.com/watch?v=kk8w1Cd8G7M Quote Link to comment Share on other sites More sharing options...
Advanced Member Tom K Posted January 26, 2011 Author Advanced Member Report Share Posted January 26, 2011 why not use SHADING to visually represent Voxel volume?

Member Gilded Posted January 26, 2011 Member Report Share Posted January 26, 2011 sculpting on a dynamic subdivision mesh and baking down to a gigavoxel display of the model... that seems like it would be amazing I don't think color info would even be necessary with the matcap system if the matcap represents a spherical voxel point Quote Link to comment Share on other sites More sharing options...

philnolan3d Posted January 29, 2011 Report Share Posted January 29, 2011 Holy shit! Billions of voxels rendered? o.O That video's been going around for a while, the problem I have with it is that it seems to be just static objects, or objects made with a procedural texture. Not quite the same as hand sculpting. Quote Link to comment Share on other sites More sharing options...
Member pluMmet Posted February 8, 2011 Member Report Share Posted February 8, 2011 I just wanted to say how excited I am about this. I can't help but feel that Pixo will screw up the Sculptris implantation of theirs and now that 3DC is getting such features I am SO HAPPY because I know it's going to be done right and most likely faster then the other guys. I'm Very Happy to have 3D Coat Quote Link to comment Share on other sites More sharing options...
Member Dreamcube017 Posted February 9, 2011 Member Report Share Posted February 9, 2011 I agree. I look forward to what's cooming to 3D coat. Quote Link to comment Share on other sites More sharing options...
