[video] Modular Lighting System - Custom Lighting Models - Episode 8

  • This video tutorial demonstrates how to refactor monolithic lighting shaders into modular, reusable components
  • It showcases the tools available in both Unity and Unreal Engine for creating flexible visual shader architectures


Compression of Spectral Images using Spectral JPEG XL

  • This paper introduces an innovative method for compressing spectral images using existing JPEG XL encoders
  • It demonstrates how cosine transforms in the wavelength domain, significantly compressing the dynamic range
  • The authors present comprehensive compression results with quality comparisons across different parameters
  • They also outline future improvements currently constrained by limitations in the reference JPEG XL implementation


New content released on GPUOpen for AMD RDNA™ 4 on-shelf day

  • AMD has published comprehensive documentation about their upcoming RDNA4 architecture
  • The release includes updates to FSR technology and the Capsaicin prototyping framework


2D Rendering with SDF's and Atlases

  • This article provides a practical overview of runtime atlas construction for sprites and text elements
  • It explores using signed distance fields (SDFs) for efficient dynamic shape packing
  • The author explains techniques for seamlessly joining polyline segments to create continuous shapes without gaps


[video] Vulkanised 2025: Slang is for Neural Graphics - Shannon Woods

  • This video provides a comprehensive overview of Slang and its capabilities for differentiable programming
  • It explains how Slang enables automatic differentiation, enhancing neural-based graphics techniques
  • The presentation also demonstrates the interoperability between Slang and Python codebases
  • It includes a practical example using gradient descent to train a Gaussian splatting implementation


[video] Soft body procedural animation

  • This video introduces the fundamentals of physics integration for graphics applications
  • It extends basic concepts to implement practical soft-body physics simulations
  • The tutorial demonstrates how to construct character animations using soft-body physics


[video] Real-Time Cloud Shadows in Unity: Optimized Shader Graph Workflow for Mobile & VR

  • This tutorial demonstrates an efficient technique for implementing cloud shadows in Unity scenes
  • The approach generates shadow mask textures through render-to-texture techniques
  • The final effect modulates the main directional light, creating convincing cloud shadow patterns
