Pur3's Morphyre

Just found owners older project Morphyre.
How do visualization projects like this work?
Any idea what 3D rendering software was used to make most of these?

More so, if anyone can explain to me how the themes menu works on the program, I would greatly appreciate it.
Apologies if this isn't the best place to post a question like this. Not sure how to get into contact with the software author otherwise.

If you know their name you can at "@" them.
What are you looking to do just curious?
Do these old visualizers still work under windows 11 anway?

Hi - yes, Morphyre is my old project.

I stopped doing work on it and started giving it away for free almost 10 years ago. Every year it costs me money even to continue to host it, so I can't continue to offer any support for it.

The rendering is done in C++, using OpenGL directly. There's no underlying engine like Unreal/etc.

I guess you're talking about the Themes menu in the personal version of Morphyre? As I recall when you select a theme it ensures that the next scene that is changed to is of that 'theme' type - I think it's as simple as that
