Hey,
I’m using Reality Capture to generate a 3D model of a telecom tower from aerial images. The results look great, much better and faster than other software in the market. However, I cannot view the mesh in Reality Capture and when I try to export the .obj format , the resulting file is 7GB. I cannot seem to find software that can handle that size. I have a very high end system, with i7 and 32GB ram etc. so I know the hardware is not the limitation.
I tried to simplify the model by reducing the tris count to 2 million from 60 million, and the OBJ output is a lot smaller ( around 14mb) but I cannot open it in any viewer either. I think this might be a bug.
My final aim is to open the 3D model in any cad package such as AutoCAD.
Thanks !
Hi shakti
It’s not a bug. it depends on your GPU RAM how big models it can handle. It depends on triangle count and texture size…
With 4 GB VRAM on GPU you can open models up to 40 mil triangles without textures…
For CAD software there could be easier way to use point clouds ( exporting under MESH ) in XYZ format that is most compatible with other applications.
Hi,
It’s the BIG lack of RC i think, it can’t load its own 3D Txtr models, and no other software that i have tried can handle hudge OBJ files, though i have tried with 3DreshaperViewer, Acute3Dviewer, MeshLab, CloudCompare, Rhino3D, FbxViewer, etc… All these softwares can’t handle OBJ file bigger than 1GB, even with a good 3D config (core I7, SSD, 64GBram, 2xGTX970). The only hope is the dev of RC own mesh viewer, or the implementation of Euclideon on RC…
And for CAD software, the best workflow is to export MESH in XYZ colored file, then import it on Autodesk Recad (free), and generate LAS or E57 file, or directly a RCP file to load it as pointcloud object on Autocad (from the 2014 release)
Regards !
