VTK Data At Point Implementation

Post by Nduduzo »

I have done the implementation of Data At Point.
Currently i am busy with Result labels at position using VTK (sticker showing value of result at specific point).

The branch can be found here:
https://github.com/stoflap/FreeCAD/tree/DataAtPoint

Feedback and comments will be much appreciated.

Hi Nduduzo,
Welcome.
I am impressed. First post and a ow branch.
The tool for labeling results does sound very useful. Can you please share some screenshots.

What i was thinking... It would be nice if using this system also the min and max values can be found.
So kind of reversed way...

Very nice work,

Could the material point be defined by a node or element label as well?

The color point is so small, the point can not be found somehow. Do I miss something. How can the colored point I have selected to get results from made visible for my poor eyes ?!

The aim for DataAtPoint is not to display color point, reason why color point displays is that i used one and the same implementation like other filters does. For DataAtPoint you select a point anywhere in an object and small color point displays then the value for that point you selected will be printed in a Console with its Unit.
