Is there a way to import a 3D model into Android?

3d, android, opengl-es

Solution

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

Here you can find my project page, which uses this solution: Github project > vsiogap3d
