nice! I'd be interested in the method they use to put everything together. My best bet is some basic structure from motion weighted by the depth sensor...or maybe it's simpler than that...
- nobbis 13y agoAuthor here. It uses color info as well as depth for tracking. Otherwise, it'd fail if you pointed the camera at featureless geometry, e.g. walls, floors.
- phorese 13y agoLooks great :) In the video it looks like you are using a volumetric representation, perhaps an Octree+isosurface extraction?
- nobbis 13y agoCorrect. It stores a volumetric signed distance function in a tree-structure, which makes mesh generation (and raytracing) simple and fast.
- druidsbane 13y agoCan it stitch together much larger captures? eg: a building exterior and interior?
- nobbis 13y agoYou can download and manually align separate captures to create a larger mesh but, no, Forge doesn't do this automatically yet. On the roadmap, but won't be in the first version.
- joshvm 13y agoLooks neat - what depth sensor were you using to generate that video? It's not totally clear to me from the comments.
