Great ! I've just purchased it and it's very effective ! Thanks. ! (The fisheye grid is so cool !)
But on my Mac, the canvas is always fitted the window and I can't zoom/dezoom the canvas or move it with with the Apple mighty mouse (without scroll wheel). So it's hard to place the vanishing points far to the sides :(. Can you solve this?
Feature requests:
-Show the horizon line and, in 2D mode link it to the vanishing points
-in 3D mode : shorten further the render distance (too much lines near the horizon make a confused cluster)
But for now it's already cool :)
