Question

Is it possible to create a simple 3D model (for example in 3DS MAX) and then import it to Android?

Answer 1

That’s where I got to:

• I’ve used Google’s APIDemos as a starting point – there are rotating cubes in there, each specified by two arrays: vertices and indices.
• I’ve build my model using Blender and exported it as OFF file – it’s a text file that lists all the vertices and then faces in terms of these vertices (indexed geometry)
• Then I’ve created a simple C++ app that takes that OFF and writes it as two XMLs containing arrays (one for vertices and one for indices)
• These XML files are then copied to res/values and this way I can assign the data they contain to arrays like this:
  
  int vertices[] = context.getResources().getIntArray(R.array.vertices);
• I also need to manually change the number of faces to be drawn in here: gl.glDrawElements(GL10.GL_TRIANGLES, 212*6, GL10.GL_UNSIGNED_SHORT, mIndexBuffer); – you can find that number (212 in this case) on top of the OFF file
