but I did't got Indices in the new .h file. I dont know that this is and if I need it but in the Teapot.h file it have it. What is the simplest way to replace the teapot? I can ask from my 3D designer to export any format.

Answer 1

Since you do not have Indices,

instead of using this code to draw your object:

glDrawElements(GL_TRIANGLES, NUM_TEAPOT_OBJECT_INDEX, GL_UNSIGNED_SHORT, 
                     (const GLvoid*) &teapotIndices[0]);

use the following code:

glDrawArrays(GL_TRIANGLES, 0, numVertices);

Where numVertices is the number of vertices in your object.

What is the simplest way to replace the teapot?

Simplest way is using Unity extension. Unity is free and supports mobile platforms. If your scene doesn't have much objects and polygons (I think object culling needs pro version) Unity provides you a WYSWYG editor in realtime. You can find supported file formats here http://docs.unity3d.com/Manual/HOWTO-importObject.html

Good luck on your journey.
