NVIDIA Falcor Real-Time Rendering Framework Beginner Guide Part 1

4 minute read

Published:

Works for NVidia Falcor 8.0, 7.0, and 6.0

Tried to write some instructions from my side on top of the original NVidia Falcor documentation (v6.0, 7.0, and 8.0), as the original Falcor’s documentation often found old and many things has changed since. This post is equivalent to Falcor’s README doc.

  • note: developers must check the latest driver version for OptiX, CUDA version, and CUDA host compiler before running
  • 1.e) and 3. is not compulsory to run OptiX, 3) is just to run default SDK examples
  • nsight visual studio edition automatically installed with CUDA toolkit installation

Unity01: Variable Rate Shading Implementation on HTC Vive Pro Eye

Published:

This is a short tutorial about how to enable VRS feature for HMD using Unity3D. However, in the recent years (2025), many of the mentioned plugins and SDK might be deprecated. The interactions (eye gaze) has shifted to OpenXR. This tutorial is OpenVR-based. Therefore, it might be better you start from OpenXR.

05: Variance, Noise, and Artifacts in Real-Time Path Tracing

less than 1 minute read

Published:

(work in progress…) Noise is also referred as error, visual artifacts. In ray tracing-based rendering, it is referred to as variance. High variance represents more noise as the number of samples has not converged enough to the actual right result of the integral (Light Transport Equation).

Ray Tracing Algorithm

Ray-Based Approaches

All the ray-based rendering pipeline, including ray casting, ray tracing, global illumination-based advanced algorithms including path tracing, photon mapping could be classified in these two generic categories. This classification is based on the light path direction. Light distribution in a scene is dynamic equilibrium, as much light is absorbed as is emitted.

Published:

Rod cells are more sensitive than cone cells and are almost entirely responsible for night vision. However, rods have little role in color vision, which is the main reason why colors are much less apparent in dim light.

GitHub Pages

  • GitHub allows only one free hosting static page against per github account
  • developers can develop their page with HTML, CSS, and Javascript.
  • very important: for this your github account name, and newly created repository name must me the same. For example, if your github account is sample-git, then your page name must be sample-git.github.io, which later will generate url https://sample-git.github.io
  • you can not push files to your repository, upload templates, or develop manually.
  • https://jekyllthemes.io/ is an awesome repository for templates.
