Today was a meditative day to once again celebrate the passage of our Sun across the exactly-ish point in the sky. Yup, I’m getting old, but hey  don’t we all? As my self-birthday gift I decided to face the hills from home to work with my laptop in the backpack (big thing for me, I would always take the bus when I need the laptop, which means almost everyday).

Equirectangular Color Map Twisted

To make the self-celebration even more complete, I decided to not only work around my physical healthy, but also to give my mind some food for thought. In the past week, professor Adriano Oliveira was troubleshooting the cycles fisheye camera for his fulldome audiovisual work. He noticed that the equidistant lens was far off the expected (for example, compare it with the BGE fisheye lens) and even the equisolid (which is great to simulate real fisheye lens (like Nikkon, Canon, …) wasn’t producing a perfect fisheye.

Equirectangular Color Map

We have been debating that, and in the end he found some nice online references for different formulas per lens type. So today I thought it was a good time to get down the code. What you see next is the comparison between the wrong and the corrected equidistant fisheyes, the equirectangular testmap I used (as known as Blender UV Color Grid ;)) and something I’m passionated about now: to use drawing softwares to do math. You can delete things, move them around, color them .. it’s perfect 😉

 

 

So have fun with the fixed “fulldome” mode. Remember, the mode can go beyond 360 degrees if you want to make some really cool images 😉

Saving trees and abusing my tablet 😉

Now, something nice … I met prof. Adriano last year in the BlenderPRO (Brazilian Blender Conference). He may have exaggerated, but he told me that the main reason he went to the BlenderPRO was to meet me. It seems that it definitely paid off. I’m not saying I wouldn’t fix this bug if someone else had reported it. But it’s much more interesting to work with someone you met.

And why am I saying that? Well, next week we have a new edition of the BlenderPRO. So if you can make to Brasilia, don’t think twice. It’s going to be an amazing event, and I hope to see you there.

And happy birthday to me 🙂
