Graphics Programming weekly - Issue 290 - June 4th 2023

[video] An introduction to Shader Art Coding

  • the video tutorial explains shader programming aimed at newcomers
  • explains how to create digital art using shaders
  • showing the fundamental concepts, tools, and mathematics required along the way
  • the example is provided using shadertoy and portrayed from an empty shader to the final result

A Quickstart Guide to CUDA

  • the article provides a tutorial on how to use CUDA for beginners
  • presents how to set up a project and an overview of the basic programming model
  • additionally presents how to interop with OpenGL

Stochastic Subsets for Bounding Volume Hierarchy (BVH) Construction

  • The paper presents a new approach for constructing Bounding Volume Hierarchies (BVH) by leveraging sampling techniques
  • the aim is to create higher quality BVHs to be maintained under real-time dynamic conditions and minimize the need for refitting
  • The presented approach involves ordering input primitives using a space-filling curve and building a Cumulative Distribution Function (CDF) for sampling

GM Shaders Mini: Scaling

  • the tutorial provides common scaling, stretching, and centering patterns when using pixel and UV coordinates in shaders
  • explaining the process for newcomers and discussing common pitfalls

Iterative 𝛼-(de)Blending: a Minimalist Deterministic Diffusion Model

  • the paper presents a rederivation of diffusion models with more straightforward concepts of mixing and de-mixing of images
  • previous models relied on advanced knowledge and practice of statistics such as Langevin diffusion or score matching

[video] Where did my intersections go?

  • the short video presents how ray-sphere intersection points behave when expressed with imaginary numbers

[video] I3D 2023 Papers Session 4 - Ray Tracing

  • the video recording ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games 2023 for Ray Tracing has been released
  • the talks covered are the following:
    • Subspace Culling for Ray-Box Intersection
    • Performance Comparison of Bounding Volume Hierarchies for GPU Ray Tracing
    • Accelerated Photon Mapping for Hardware-based Ray Tracing
    • Importance-Based Ray Strategies for Dynamic Diffuse Global Illumination

Rendering Engine Architecture Conference - 2023

  • open, digital, and freely accessible conference covering many rendering engine architectures is happening on June 5th and 6th
  • talks from HypeHype, Activision, Ubisoft, Wētā Digital, and more
  • the talks cover modern mobile rendering, task graph architecture, decoupled rendering, shader pipeline, and much more
