How to move object or rotate the object interactively ? about vedo HOT 14 OPEN

I figure it out. Just pressing button a. I have a second question how do we scale an object (i.e. similar to blender by pressing s and moving left or right).

from vedo.

you right-click and drag the mouse.

Dear Marco,
Is there anyway we can access the axis of the object and its orientation ?
I want to do thing similar to this post. However, I would like to define my own transformation matrix, button and much more. Therefore, is there anyway can I get the information about orientation and axis of the object ?

from vedo.

Sure you can access it by

myobj.transform

and

myobj.transform.matrix

To apply a trasformation to a specific object you can use

myobj.apply_transform(...)

Hey Marco,
Is there any way to make the line rotate or move together with the object (the purple one) when using mouse to move or rotate the object ?

from vedo.

Yes you can create an Assembly:

assem = myline + myobj
show(assem)

from vedo.

Did you manage to do it?

Since vedo is made on VTK, Can you create a python code to make this function ?

from vedo.

I am not good at coding yet and I believe you could help me to create something like this in vedo.

from vedo.

You can create a picture-in-picture rendering with any sort of 3d object or axes.
This is a good example to start with

thank you for your assistance. I have one question. When we apply the transformation, the mesh.vertices still have the ols data from the dataset. How do we get the new coordinate information after transformation ?.

from vedo.

*old

from vedo.

No, mesh.vertices will hold the new coordinates after .apply_transform(T)

from vedo.

I think I combine the mesh and other mesh into assembly and when I apply transformation matrix. The mesh.vertices inside the assembly data still hold the old data.
