- outlines best practices and architecture strategies for real-time path tracing in modern game engines
- recommends budgeting rays per signal rather than per pixel, combining shallow bounces with radiance caching and ReSTIR
- discusses acceleration structure updates, firefly management, and tuning ray dispatch alongside denoising and upscaling
- covers AMD driver support for DirectX 12 Agility SDK 1.620 retail and 1.722-preview on RDNA GPUs
- highlights preview DXR features including Clustered Geometry, Partitioned TLAS, and GPU-indirect acceleration structure builds
- details retail features such as DirectX Dump Files, Extended PIX Markers, and Advanced Shader Delivery integration
- proposes a lightweight neural texture upscaling method integrated directly into the texture sampling stage
- trains a single generalized MLP on diverse texture patches to avoid per-asset retraining or asset pipeline modifications
- reduces disk storage and runtime VRAM consumption while providing non-divergent execution on the GPU
- covers visual improvements to the sky, atmospheric scattering, and cloud rendering in a stylized sailing game
- verifies multiple scattering missing in POV-Ray using a custom Rust ray tracer and precomputes updated cloud LUTs
- details Godot shader tricks, including upward-pointing cloud normals for indirect light and view-vector adjustments for small planet horizons
- reflects on twelve years of developing the open-source Spartan engine from scratch
- explores the milestone of reaching a shippable game engine state with real-time path tracing, Lua, and visual scripting
- shares lessons learned from solo engine development, open-source persistence, and industry career impact
- provides a collection of interpolating spline algorithms
- implements C2 cubic, G2 cubic, Hobby, Adobe kappa-Curves, and a custom S9 G2-continuous low curvature variation
- outputs either cubic or quadratic Bézier curves
- introduces an open-source terminal UI tool for inspecting per-process GPU memory and compute activity
- supports Windows with NVIDIA/AMD telemetry and Intel WDDM activity, as well as native Linux, WSL, and Apple Silicon
- explains how to handle offscreen render targets
- presents the concepts through an ImGui system that allows the activation/deactivation of render passes at runtime
- walks through managing descriptor sets, pipeline layouts, and frame setup across render passes
- explains Thompson sampling as a heuristic for balancing exploration and exploitation in multi-armed bandit problems
- visualizes sampling from Beta distributions to model reward probabilities and choose optimal actions
- covers AMD driver support for DirectX 12 Agility SDK 1.620 retail and 1.722-preview on RDNA GPUs
- highlights preview DXR features including Clustered Geometry, Partitioned TLAS, and GPU-indirect acceleration structure builds
- details retail features such as DirectX Dump Files, Extended PIX Markers, and Advanced Shader Delivery integration
