The Juggler: In Rust
Back on the theme of learning to program by taking on a meaningful project — we have another raytracing demo — this time using Rust on the Raspberry Pi. [Unfastener] …read more Continue reading The Juggler: In Rust

A ZX Spectrum Raytracer, in BASIC
[Gabriel Gambetta] knows a few things about ray tracers, being the author of Tiny Raytracer, a raytracer written in just 912 bytes of JavaScript. As a long-time fellow sufferer of …read more Continue reading A ZX Spectrum Raytracer, in BASIC
Ray-Traced Doom Really Shines!
We’re huge fans of taking retro games and adding new graphics features to them, so you had to know that when [Sultim Tsyrendashiev] released his ray-traced Doom engine, we would …read more Continue reading Ray-Traced Doom Really Shines!
Excel Ray Tracing with Help from C
It isn’t news that [s0lly] likes to do ray tracing using Microsoft Excel. However, he recently updated his set up to use functions in a C XLL — a DLL, …read more Continue reading Excel Ray Tracing with Help from C
Ray Casting 101 Makes Things Simple
[SSZCZEP] had a tough time understanding ray tracing to create 3d-like objects on a 2d map. So once he figured it out, he wrote a tutorial he hopes will be …read more Continue reading Ray Casting 101 Makes Things Simple
A SNES, Ray Tracing
A trick famously used by Nintendo to keep its slowly aging SNES console fresh against newer competition was to produce new games with extra support chips in the cartridge to push out hitherto-unthinkable performance. Chips such as the famous SuperFX gave us 3D polygonal graphics, but it would have been …read more
Experiments In 3D Graphics Via Excel
3D graphics were once the domain of university research groups and large, specialized computing systems. Eventually, they were tamed and became mainstream. Your phone, tablet, and home computer are all perfectly capable of generating moving 3D graphics. Incidentally, so is Microsoft Excel.
This is the work of of [s0lly], who …read more
Minecraft Is Getting a Whole New Look With Ray Tracing Support
Minecraft’s upcoming support for ray tracing will introduce a new look for Minecraft, adding realistic lighting, volumetric water, vibrant colors, and emissive textures
The post Minecraft Is Getting a Whole New Look With Ray Tracing Support appeared fi… Continue reading Minecraft Is Getting a Whole New Look With Ray Tracing Support
Tiny Ray Tracer Fits In 64 Bytes
Throughout human history, people try to make the biggest, the fastest, and — sometimes — the smallest. [Hellmood] falls into the latter category and proves it with a 64 byte interactive 3D raycasting application for MSDOS.
Why MSDOS? We suppose why not? The .COM file format is lean, and you can take over everything without a lot of work. If the program were huge, it wouldn’t be very impressive. There are 64 shades of gray which is odd looking these days, however there are versions that use various color palettes and each one fits in 64 bytes or less. There’s …read more
Hack Excel for 3D Rendering
[C Bel] teaches Excel and he has a problem. Most of us — especially us Hackaday types — immediately write a VBA (Visual Basic for Applications) macro to do tough things in Excel. Not only is this difficult for non-technical users, but it also isn’t as efficient, according to [C Bel]. To demonstrate that VBA macros are not always needed, he wrote a 3D game engine using nothing but Excel formulae. He did have to resort to VBA to get user input and in a very few cases to improve the performance of large algorithms. You can see his result …read more
