Python: How to Automate Shape Keys in Blender

Blah Blah Blah

The human mouth is kind of a bastard. Animating it frame-by-frame requires a patience that I just don’t have. Blender has shape keys that can help you mold lips into different configurations for each sound, but you still have to set keyframes to match up with a particular word at each and every frame.

Or you can be lazy. Like me.

Blender: How to Scale Down Coordinates for a Map Scene

A GifGuide 2 Maps

Getting coordinates to scale properly to Blender units has been extremely frustrating for me since I started attempting more 3D maps. So, finally, in a fit of rage this weekend, I wrote a function to do it for me.

It scales the latitude and longitude down along the Z (height) and X (width) axes, taking into account the size of a base map oriented along those axes. In my version, it places a sphere at each coordinate set, but that can be easily changed to other objects.

Processing: How to Make Transparent Textures

Alice

After a long vacation, a wedding, a bad flu, and a whole mess of planes, trains, and automobiles, I’m back to talk about textures. I love playing with transparency in scenes, but scripting transclucency is a bit unusual in Processing. The normal Processing canvas doesn’t support an alpha channel, so it requires something called PGraphics().

Blender: How to Loop an Image Sequence into Textures

Animating Blender Textures With Processing

Animated textures in Blender is a thing! Immediately after finding that out, I set out to script a grid crawler texture in Processing. Because no one in their right mind would want to draw that by hand.

A Bit Of Everything has a post with the logic for a static grid, but somehow getting an animated version ate 3 hours of my life. All in all, it took about 12 tries. What I love  about Processing is that even bad guesses can have pleasing results.

Python Update: How to Animate Text in Blender

WhereIsMyMind

I’m generally opposed to functions that overload on parameters. But seeing as how Blender functions do it all the time, I figured I’d go nuts for this updated text animation function.

Processing: How to Code A Wheel Cipher Layout

Thomas Jefferson's Wheel

I’ve been reading Code Breakers by Rudolf Kippenhahn. What hooked me into it was the part about the Wheel Cipher, a device envisioned by Thomas Jefferson in the late 1700’s. You can see Jefferson’s note about the wheel in his very own, genuinely awful handwriting here.

Python: How to Loop through Every Vertex in a Mesh

The Spiral

Sometimes I get embarrassingly excited about being able to do things in Python that I will probably never need to do again. This is one of those times.

I had a mesh—a plane that I had turned into an a spiral walk-way. And I had the thought, this thing can’t have walls. Eventually I want the walk-way to be the center of a large arena that’s coated in fog. And the only way you’d really be able to see that it’s a spiral is if it’s semi-transparent and lined in lights.
