herebedragons

0 1,715 7.3 C

A basic 3D scene implemented with various engines, frameworks or APIs.
foolrenderer

1 889 1.8 C

The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
LinaVG

1 171 7.3 C

2D Vector-Graphics library for drawing anti-aliased convex shapes, lines and texts.
FreeOberon

1 131 7.8 C

Cross-platform IDE for development in Oberon programming language made in the classical FreePascal-like pseudo-graphic style.

Project mention: FreeOberon cross-platform Oberon language IDD | news.ycombinator.com | 2023-11-12

Quick look at https://github.com/kekcleader/FreeOberon/blob/main/src/make....:
It uses ofront (Oberon-2 to C translator), and let GCC do the heavylifting.

raytracer

3 74 0.0 C

C++ raytracer that supports custom models. Supports running the calculations on the CPU using C++11 threads or in the GPU via CUDA. (by maxilevi)

Project mention: CUDA Accelerated Raytracer | /r/hypeurls | 2023-06-15

software-renderer

1 54 7.8 C

Software rasterizer in C

Project mention: Software rasterizer written in C and compiled to WebAssembly | /r/cprogramming | 2023-10-01

A little bit about this project: it is a pure C software rasterizer using SDL2 for keyboard / mouse / graphics handling. It has perspective correct interpolation, depth buffer, vertex and pixel shaders and a bunch of other stuff - please check the full readme and code at https://github.com/gnikoloff/software-renderer

spotify-GL

3 9 2.6 C

just a OpenGL spotify ripoff

Project mention: Spotify in OpenGL | /r/opengl | 2023-06-13

InfluxDB

www.influxdata.com sponsored

Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
rototiller

1 6 9.4 C

Collection of software-rendered realtime graphics compositions, see https://rototiller.pengaru.com. Github is only a mirror.

Project mention: What I've learned about flow fields so far | news.ycombinator.com | 2024-01-02

I implemented a something similar[0] a while back in rototiller[1], there's a short low-res youtube clip here[2].
It was a fun little hack, I didn't realize this is a thing. I was just messing around with an idea of pushing particles through a cube of tri-linearly interpolated direction vectors, without simulating any actual physics like mass/friction/fluids or anything like that.
Something which surprised me was during development I just populated the cube of vectors with randomized vectors, fully expecting I'd have to do something more intentional and clever before it was interesting to watch. But the emergent structure of the flow paths even with the pseudo-random vectors was surprisingly interesting and I just left it at that, with the addition of a second randomized field the direction vectors would be interpolated between in a ping-pong manner. When one field is dominant, it re-randomized the other, resulting in a continuously-looking evolving field...
