Thanks for the link Alex, but this is for the 2D widget. Works fine
for me too. My problem was with the 3D widget.<br>
<br>
I have actually switched to the 2D widget cause I suspect there are
bugs in the 3D widget causing the erratic positioning. Hope to look
in further on that later on. The 3D widget is better looking than
the 2D one imo.<br>

This question is regarding usage of the 3D slider widget.<br>
I have been using world coordinates to set the widgets
position, and that seem to be working fine.<br>
<br>
Now, however, I would like to simply place the widget
horizontally at the bottom of the render window. Whats the
right way to do such?<br>
<br>
I imagine I would need to go from normalized (2D) display
values, say (-0.8, -0.8) & (0.8,-0.8) which would be at
the bottom of the window, to world coordinates (3D).<br>
Any pointers on how to achieve this?<br>
<br>
The widget position would need to be recalculated if the
camera changes.<br>
Thanks,<br>
