Hi list all,
I'm begin study qt3d(qt5.5 version) now. And I want to found some
examples about 3d model mesh and sub mesh operation.
I google found a good example QtQuick3D Tutorial - Car3D (
http://www.youtube.com/watch?v=VvQ_NHKtHwE ), but this qt3d is V1.0
and the example did not run on qt3d 5.5 or later.
Has anyone know where could found example about qt3d to operate 3d
model mesh and sub mesh like above Car3D examples ? Thanks
Well, in making of this car demo,
https://www.youtube.com/watch?v=zCBESbHSR1k we simply exported the
submeshes we needed explicit control over as separate obj files and
loaded each one usign a Mesh component aggregated to an Entity. Each
Entity has it's own Transform component that we then bind properties to
QML expressions that reference the Qt Quick Controls, e.g. slider values
or boolean switches.
You can also have all meshes in a single OBJ file and reference the sub
mesh you wish to render in the Mesh component. We tried this but found
it to be better to split them out as it allows more work to be done in
parallel at start up, leading to faster startup times.
Cheers,
Sean
