Check out this great new tool that acts as a 3D canvas.
A Designer Jacopo Colò has created a new free tool, which is essentially a 3D canvas, called Penzil. In Penzil you can move around and everything you draw there stays in place. Jacopo has also released a tutorial on how this tool works on his Twitter page.
According to Jacopo, he started working on Penzil after seeing Blender’s Grease pencil, because he wanted to be able to sketch in 3D on his iPad, without a laptop and a graphic tablet.
