Splats are 2D. But again, you'll need to READ to understand that. Come on, the paper I gave is 8 pages long.... you are only able to watch youtube videos ?? The splatting approach is just as old as 2001, in "Surface Splatting" from Zwicker et al. (8 pages as well, and it's the first google result), but there are other slightly different older works (Qsplat in 200...). The point based rendering approach though is as old as 1985 (The Use of Points as Display Primitives, by Levoy and Whitted).

Just check the reference [EHK*06]. Ok, nice tutorials about rendering and such... but why you refer me towards them is beyond me ? http://www.real-time-volume-graphics.org/?page_id=28 Even the last document clearly states/shows that compression is somehow needed: http://www.cg.informatik.uni-siegen.de/data/Tutorials/EG2006/RTVG14_LargeVolumes.pdf So the problem of compression is still not solved. Thanks anyway it was slightly interesting :) Bye, Skybuck :)

I haven't done so yet... but maybe that's about compression. Bye, Skybuck.

Splats are 2D. Then I guess it's the same since the vector balls are 2D as well, just their coordinates are 3D. Bye, Skybuck.

I scanned through all the documents and the compression problem remains. Bye, Skybuck. |
