Processing: How to Make Transparent Textures


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.

Processing: How to Randomize Textures


Scenes with custom textures always seem to turn out better for me, but they’re hellish to make. I’ve spent hours in GIMP hand-drawing patterns, carefully testing out layers to get  effects. It’s a hassle.

However, I’m learning to automate more of that sort of thing with Processing. What’s really nice about that is you can get a texture that changes subtly every time you run the script if you use the Random function to assign coordinates, weights, and transparency values.

Python Update: How to Animate Text in Blender


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 Get Sliding Text in Blender

This is Bob.

This is Bob. Bob is a gelatinous organism from outer space. He’s also a bit of a diva, so he requires that he be announced by text that drifts upwards in a graceful and organized fashion.

So that’s how I spent the first chunk of my long weekend—figuring out text objects in Blender. For the sliding script, just scroll to the bottom. For more description, keep reading below.

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.
