Oh um... use your mouse to draw, then press space to see it in 3D! Press space to toggle between drawing and viewing. ================================================ Use the tools on the left side of the screen to erase, clear, undo, redo, and draw! DECREASE the "glow" variable TO REDUCE LAG. Use the up and down arrow keys to change the height variable! The height variable is how high you want the z axis of your lines to be when it is in viewer mode. Leave a love and fav if you like it, it took some time to make this!
