For light-weight examples that is fine in some cases but then you open a 
can of worms with queries like "so how do I just use a texture or mesh 
from disk rather than tweaking shaders or writing a ton of C++?" and 
"why are my generated textures horribly aliased?" which is a whole topic 
in it's own right. Also generating interesting meshes in code is 
non-trivial and a huge time sink, especially when you need texture 
coords, tangents, normals etc.

I think putting simple examples in the qt3d repo and additional examples 
that use heavier assets such as meshes form modelling tools, higher-res 
textures, cubemaps, etc into a new qt3d-examples repo would solve both 
problems.

The examples in the qt3d repo should show how to do the basics that 
don't depend upon a lot of data e.g. using cameras, simple geometric 
meshes, basic materials etc. Then the new repo would contain more 
visually pleasing examples closer to expected real-world usage but 
remaining an optional download to those that are interested.
