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.

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: How to Loop through Every Vertex in a Mesh

The Spiral

Updated: May 2021

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.
