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 Randomize Textures

TheHallCompressed

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: 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.
