About this app

Load 3D models and see how to do it with this open source code application.
Formats supported currently: *.obj, *.stl & *.dae

The main purpose of this app is to show how to draw in android using the OpenGL 2.0 by sharing the source code. So please, don't expect this application to be much richer or nicer than the ones already published in the app store, but at least it's unique in the sense it's opened to anyone who wants to contribute or don't want to start a similar project from scratch.

As this is my first android app and Im still learning the OpenGL 2.0 language, it is highly probable that there are bugs; but I will try to continue improving the app and adding more features. So please send me your comments, suggestions or complains to andresoviedo@gmail.com; or leave a nice comment :)

The app comes with some included 3D models that were taken for free from Internet

Currently implemented features:
* OpenGL ES 2.0 API
* Formats: OBJ (wavefront), STL (STereoLithography) & DAE (Collada)
* calculation of normals
* transformations: scaling, rotation, translation
* colors
* textures
* lighting
* wireframe & points mode
* bounding box
* polygon with holes
* smoothing
* object picking
* camera support!
* tap to select object
* drag to move camera
* rotate with 2 fingers to rotate camera
* pinch & spread to zoom in/out the camera
* skeletal animations (collada)
* ray collision detection
* stereoscopic 3D
* lightweight: 1 megabyte

Features coming soon:
* glTF support
* 3D without glasses
* Augmented reality

I like apps that do one thing and do it well. This is one of those apps. It simply displays a slowly spinning STL file and allows you to rotate the image manually. The ability to see a skeleton view and texture an STL image is a nice feature. The stereoscopic viewing features are a nice touch. It gives me a reason to dig out my old Google cardboard VR glasses. This is an outstanding app for viewing 3d STL files.

Does not render anything on my screen! Yes, my device supports OpenGL ES 2.0 and, this is the only renderer that does not work. RESPONSE: Yes, it works now, but if a MTL is available and the supporting files are in the same directory, users shouldn't have to select each file separately!

ir works great when viewing a 3d model along with the wireframes, but when i load a png texture into the model everything turns black, interesting because it doesn't happen when i upload the texture into a default model like the penguin for example, it has something to do with the 3D model i loaded? it is a car btw, and also when i remove the texture everything returns to normal.
