Java 3D: How to Create an Acorn-Eating Squirrel (with Source Code)

#Java3D #squirrel #acorneating
This video explains where to download a 3D squirrel model, and how to create two poses of an acorn-holding squirrel in Blender.

The video also explains how to write code to switch between the two poses to create an acorn-eating squirrel.

In the next video, I will add a throwback pomeranian, Leo, to the scene so that he can communicate with the squirrel.

I noticed that sometimes we could not access BlendSwap which said "It's likely the website's certificate is expired."

Like Google Poly 3D models, I created the page where you could download BlendSwap 3D models I used in my videos, just in case you couldn't access the site.

Click the corresponding link. Click the download mark button at the top right to download the model.

Poly was shut down on June 30, 2021. You can download all the Poly .obj models I used in my videos from here:
