LibThree

LibThree is a standalone application that allows you to import various 3d file formats and visualize them like a pro. 

Create a library with your 3d models and browse them similar to ACDSee, but with 3d file formats. Metadata can be attached to each file and searched, to quickly find what you need.

Currently, two render engines are available - real-time OpenGL  and photorealistic CPU ray tracing. GPU ray tracing is in the works, to improve both existing engines. CPU and GPU denoisers are available to avoid huge rendering times due noise.

Export to GLTF 2.0 is possible, so you can upload your work to any GLTF compatible site.

Note that this tool is in a beta stage and you can stumble upon various issues. For more information and support visit http://libthree.com/
