What is a Composed object

Hello Mr. Sternbauer,

You can import obj-files for building the composed object. The point here is that you demonstrate how to handle the matrix manipulations when animating parts of the objects. In contrast, the hand-crafted object should not be created via modeling tools like Blender because this part is about demonstrating that you are able to create a single object with the correct properties (i.e., normals that are needed for the shading). I tried to clarify this by slightly extending the description on the moodle page:

Hand-crafted object
Create one scene graph node that renders a hand-crafted 3D shape (5-25 vertices; not a cube, sphere, quad, or loaded model). Fully specify properties for this object, i.e., vertices, normals, and texture coordinates. This object must not be imported from external object files created via modeling tools like Blender. However, you are free to use imported objects for other parts of your scene.

Best regards,
Marc Streit

Thanks for the answer. I was a bit confused about "You can use obj files if you want to, but you won't get any points for it." and thought this also means that thee composed object consisting ob obj-files would result in lost points. Thanks for the clarification.

Dear Professor,
Sorry to insist because now i'm a bit confused.
If we use an .obj file for the composed object that will not result in lost points ?

Best regards

Exactly. What is important to note is the difference between the composed object (must be multiple SG-nodes, can use .obj files) and the hand-crafted object (may be a single SG-node, must not contain .obj-files).

I hope that clears up your confusion.

Kind regards,
