Add sidewalk? - sl60 - 01-27-2022
[attachment=7403]
Is there a way to take a flat 2D image of a building (front view, no perspective) and add a sidewalk coming off the porch entrance that looks 3D? See example.

Using your example. Guess a horizon, there will be a vanishing point (VP)
All parallel lines converge at the VP ie. Edges of the path, any joints in the path.

Now that is the sort of response guaranteed to get you overlooked. You already know all about it. Use the paint tool and get painting.
However;
Make a new layer Layer -> New Layer
Use the rectangular select tool and make a rectangle for the path.
Fill the selection / paint in it / make your pattern
Turn the selection off. Select -> None
Reduce the layer size to smallest size Layer -> Crop to Content
Use the Perspective Tool Tools -> Transform Tools -> Perspective (shift P)

If you will please re-read my response that is not what I said. I said that I already know all about the principles of perspective--what I don't know is how to apply these to a flat 2D image in Gimp to simulate actual perspective lines in 3D.
Thank you for the advice.

this is one way, https://i.imgur.com/kafReLE.mp4 The added path is the same as your example.
