ray-tracing

The article describes the author's project to write a ray tracer in the esoteric programming language Brainfuck, exploring the technical challenges and design decisions involved.

This paper introduces a channel-informed neural network for physical-layer key generation, using received IQ measurements and ray tracing augmentation to improve key diversity and pass NIST randomness tests.

Arm introduces the Mali G2-Ultra NX GPU, its first AI-native GPU that integrates neural acceleration into the graphics pipeline to deliver desktop-class mobile gameplay with AI-enhanced graphics.

The paper introduces Physics-Unrolled Hybrid Neural Operator (PU-HNO), a model that predicts high-fidelity indoor radio maps from low-fidelity ray-tracing outputs by capturing propagation effects like reflection, diffraction, and scattering, outperforming existing baselines.

A hobbyist compares Qwen3.8 and Qwen3.6 AI models in generating ray-tracing code in BASIC, finding that Qwen3.8 iterates to better results independently.

This paper presents a technique for ray tracing massive numbers of animated triangles by decoupling animation from triangle count using tetrahedral cages, enabling scenes with hundreds of millions of animated triangles at 60 FPS on consumer GPUs.

Peter Gostev built a Doom-like game using SQLite as the game engine, with ray tracing via recursive CTE, and integrated with Datasette for a real-time web interface. The project was created using GPT-5.6 Sol and demonstrates the creative potential of using SQL for game logic.

A ray tracer implemented entirely in ClickHouse SQL queries, rendering images to PNG without any external code or UDFs. Demonstrates procedural terrain, CSG geometry, and parallel pixel computation.

SedonaDB 0.4 introduces RayBooster, which uses GPU ray tracing cores to accelerate spatial joins, outperforming an H100; the research was accepted to VLDB 2026.

A technical blog post deriving how to compute camera rays from a view-projection matrix for ray tracing, with shader code and handling of numerical stability.

A developer built Luz, a C++20 path tracer from scratch with zero dependencies, featuring Monte Carlo path tracing, global illumination, BVH acceleration, and a Blender-to-Luz exporter.

Veteran Splinter Cell designer Clint Hocking argues that modern realistic lighting techniques like ray tracing make stealth games harder for players to read, as realistic shadows and ambient occlusion blur the clear visual cues used in older games. He calls for developers to rethink how they use advanced lighting to maintain gameplay clarity.
