Distorting a 2D object to give the appearance of 3D Space
I'm trying to recreate the following image from Yoshua Bengio's slides:
So far, I've made the flat rectangle object, but I'm having a hard time figuring out how to "distort it" in Inkscape. The path tool lets me do this for individual paths drawn with the pen tool, but I can't figure out how to do it for the entire object.
In the following example I've converted to path rectangles, circles and text just by grouping all the objects and using Path...Object to path. With the group selected, you need to show the Path effects dialog (Path...Path effects or Ctrl+Shift+7):
Clicking the "+" button, you can add the Envelope deformation effect:
Now you need to perform some manual work. The effect allows to apply a deformation to each side of your object.
You can start with the top side, by clicking the related Edit on-canvas icon:
Dragging the nodes you can see immediately the deformation, e.g.:
And so on:
With a little tweaking you can achieve a result similar to the desired one.
