Principia VS blender

Principia is extremely impressive, they document all their math here: https://github.com/mockingbirdnest/Principia/tree/master/doc...

One interesting detail is that the source code makes extensive use of non-ASCII identifiers, for mathematical symbols and for the names of mathematicians. One of the two primary contributors is also an active contributor to Unicode

KSP2 is still patched conics. Also here's a free n-body mod made by modders, https://github.com/mockingbirdnest/Principia

Principia - 𝑛-Body and Extended Body Gravitation for Kerbal Space Program

But one should just be aware that KSP simplifies by only tracking the strongest source of gravity. This turns all orbits into actual ellipses. But there is a mod called Principia that replaces it with the proper thing, thus allowing for very chaotic (but cool) flight paths using less thrust.

Principia has n-body

Install Principia and Real Solar System, then try again :P

Theres a mod that changes that to N-body simulation, it's called Principia

I'd suggest looking at their readme: https://github.com/mockingbirdnest/Principia

Please try looking through some large open source projects and contributing major contributions by familiarizing yourself with the code base, learning multiple programming languages, and not having major bugs in your code. I'd imagine you wouldn't want to do this.

Here is a weblink: https://github.com/blender/blender

This for example is the complete source for blenders procedural noise functions: https://github.com/blender/blender/blob/main/source/blender/blenlib/intern/noise.cc

Maybe you're only using object lights. To make it look like Material Preview, you'd want to use an environment texture [instead]. If you don't want to have to find them in the blender folders, here are the ones listed in Material Preview, forest.exr being the default

forest.exr https://github.com/blender/blender/tree/master/release/datafiles/studiolights/world

Everything was good. And then a developer decided to abandon the custom CLAMP macro and use the standard std::clamp function. And the commit that supposed to make the code better looked like this:

Or simply git clone official public mirror and build it yourself.
