Point3d position - kreativasas - 04-22-2020
Hi everybody, I need an help..
I have in my scene a sphere and a 3dpoint wich is the centerposition of the sphere
When i make a transformation to the sphere i need to move the point to the new sphere centerposition but if i read the new center position of the sphere after the transformation i get the original position ever.
How i can move the point to the new center position?
Thanks for replies

Do you mean SphereVisual3D.CenterPosition as the "centerposition"?
You have two options:
1) instead of applying a TranslatTransform3D on the SphereVisual3D, you can just change the value of the CenterPosition.
2) to get the transformed centered position you can use:
var transformedCenter = modelVisual3D.Transform.Transform(sphereVisual3D.CenterPosition);
Note that transformation are hierarchical - so you can have a hierarchy of objects - for example:
ModelVisual3D
ModelVisual3D
SphereVisual3D
BoxVisual3D
So if you apply the transformation to the first ModelVisual3D this will transform all child objects, but CenterPosition on SphereVisual3D and BoxVisual3D will not change - the values of those properties are defined in the local coordinate system (and not in world coordinate system).
