Python: How to Start Scripting in ArcGIS

Header

Python in ArcGIS is intimidating, so I’m starting simple. This is a quick walk through of how to load a script for use and what a basic Python script looks like.

VBA: How to Get A List From a Range of Numbers

Header

A couple months ago, I did the exact opposite of this. I called it the ListToRange() Function. It’s weirdly helpful at work because I have to go back and forth between having numbers listed out and then having them clustered for other things.

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().

VBA: What is a Range Object?

Range Objects

“Range object” is an unnecessarily intimidating term for a collection of cells within your workbook. Say you need to run some complicated math or formatting over the same cells over and over throughout a long script. You could call on the column number and row every damn time, but who wants to do all that typing?

VBA: How to Code a Letter Frequency Chart

Rolling Stones

I recently picked up a book called “Ghost in the Wires: My Adventures as the World’s Most Wanted Hacker” by Kevin Mitnick. To be totally honest, I’d never heard of Mitnick before. He was a little before my time—when he was arrested in 1995, I was still struggling to understand why the hell I had to learn fractions and everything I knew about computers was based on WarGames.

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

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.
