The VRML, X3D and STL viewer for Android.
*This version should fid some bugs with some newer device-specific OpenGL-ES low level libraries that gave black screen issues. I was able to recreate the issue, and solve it, but I don't have a wide range of devices. Some functionality currently disabled, until core is once again stable*
Display local or web-based STL, VRML97 and X3D files.
Rotate or zoom STL files; X3D files you can examine, and walk around your 3D Scene. Use one finger to rotate or walk, two to either zoom or move up and down, depending on the Nav setting.
Decide whether your model renders quickly for interactivity, or slower for "picture-perfect" screen snapshots. STL models can be analyzed for 3D printability, should you wish.
It is the only app on the App Store that will check for STL Watertight and Manifold issues for 3D Printer pre-verification.
CAD programs such as Catia, AutoCAD, Sketchup, OpenSCAD, SoldidWorks, MATLab, in fact almost any CAD program, will export in STL, VRML, or X3D.
The rendering engine has a proven track record on desktop computers, and has been downloaded millions of times by scientists, researchers, academics, hobbyists, Augmented Reality experimenters; the rendering engine (FreeWRL) is well proven and users have told us that it can run up to 10x faster than other rendering engines.
We are well on our way to giving you THE tool for model verification, manipulation, and display.
There are many additions planned for FreeX3D - it is a top-notch VRML/X3D viewer, and a great STL (stereolithography) file manipulation tool for the 3D printer and CAD viewer crowd.
Make sure you enable updates when you purchase this App.
