A 3D gravitational simulator, written in rust

Björn Steinbrink 636a7cf356 Recombine mass, s and child data into a node tuple With the values spread across three Vecs, this means that we touch three cache lines when we need all values. That would be fine if we went through the data sequentially, but since the octree makes us jump around wildly in memory, we're likely only using a single value from each cache line. Since we need all four values in the hot path, and all four togehter nicely fit into a single cache line, it's more efficient to stuff them together. Really this should be a struct, but I'm lazy...		8 months ago

galaxy3d-rust

A simple 3D gravitational simulator I wrote in Rust.

Usage

First, generate a 3D video.

cargo run --release -- create

This will generate a video.3dv file.

Next, watch the video.

cargo run --release -- watch

This will load the video.3dv file, so that you can watch it.

This is very much a WIP, and all parameters are hardcoded for now.
