How to display Grid or Bitmap in BBox around the user about droidar

[GoogleCodeExporter]

ok so you have some bitmap objects (the raster data) and you want to create a 
box around the user with this bitmaps as textures? check the GLFactory there is 
some example code how to create textured shapes.

Thanks,
so I was able to combine the Vec adding from the mesh with the Textured2dShape.
My only problem now is, that with the following code produces a triangle, not a 
rectangle:

Textured2dShape s = new Textured2dShape(IO.loadBitmapFromId(myTargetActivity, 
R.drawable.dummy), "imgName");
Vec start = new 
Vec(    s.myPosition.x-(s.getTextureWidth()/2),s.myPosition.y-(s.getTextureWidth()/
2), 0);
s.add(start.copy());                    // 1.
start.x += s.getTextureHeight();
s.add(start.copy());                    // 2.
start.y += s.getTextureWidth();
s.add(start.copy());                    // 3.
start.x -= s.getTextureHeight();
s.add(start.copy());                        // 4.

Do I have to close the "path" somehow?

Second question is: how can I ensure the right position of the image in the 
virtual coordinate system? Is there a wax to transform from geo-coordinates to 
virtual coords? 

kind regards!

When you take a look at the GLFactory ( 
http://code.google.com/p/droidar/source/browse/trunk/droidar/DroidAR/src/gl/GLFa
ctory.java ) there is a method 

"public MeshComponent newTexturedSquare(String bitmapName, Bitmap bitmap,float 
size) {..."

take a look in there or use this method directly. The Textured2dShape is not 
the right choice here i think, bette use the TexturedShape like in the method. 

Its a triangle because opengl can only draw triangles so if you want to create 
a rectangle you have to use 2 triangles (like in the method;)

Thanks alot Simon!
I will try that soon. My last little question: I saw a Blender3D Obj file in 
the raw folder and found the ObjParser. Does parsing this 3D models actually 
work?

Jep, object parsing and displaying these objects (md3, obj, 3ds and some other 
i think, so also animated models!) does work but you will have to use the 
ModelLoaderAdapters project ( 
http://code.google.com/p/droidar/source/browse/#svn%2Ftrunk%2FModelLoaderAdapter
s ) and you will need the libgdx project ( http://code.google.com/p/libgdx/ ) 
to make the ModelLoaderAdapters work. But if you do so it is easy to load 
external models, just check the demo setup in the ModelLoaderAdapters.

i finally did a short screencast about how to load 3d models:
