I just upgraded my pc to windows 10 creators update which has Microsoft Paint 3d. I didn’t have a lot of time to spend with it so I just did a simple doodle to test it out along with another free app called plumbago which is a notebook writing sketching app. The first image below I did with plumbago and a stylus.
I then saved it as a png and loaded paint 3d and created a simple blue 3d sphere. The eyes, mouth, and north pole err I mean hair are called stickers and you can place them on the 3d objects. Finally, I loaded the first image as a custom sticker and stretched it over the sphere. It also supports 3d text which is what I did the date in. Lastly, I used a yellow light source on the first and red light source on the second and exported them to standard jpg format.
My main problem with plumbago is I couldn’t figure out how to lasso some of the image and enlarge or shrink it. I figure it must be possible but with the ruled lines maybe it disallows it. All in all both programs are pretty neat. I’m sure I’ll try them out again when I have more time so I can gingerly doodle more and hopefully better images. 🙂
