Overview

The Reference Path Tracer Code sample

This is a supplemental code accompanying Ray Tracing Gems II, Chapter 14: The Reference Path Tracer. Code is based on IntroToDXR and implements a path tracer described in the article. The sample application loads GLTF scenes, specified via command line. The core of the path tracer can be found in single HLSL file - PathTracer.hlsl.

"Reference Path Tracer

Command Line Arguments

  • -width [integer] specifies the width (in pixels) of the rendering window
  • -height [integer] specifies the height (in pixels) of the rendering window
  • -vsync [0|1] specifies whether vsync is enabled or disabled
  • -scene [path] specifies the file path to a GLTF model
  • -scenePath [path] optionally specifies the root folder where scene data files can be found

Supplemental source code for "A Halfedge Refinement Rule for Parallel Catmull-Clark Subdivision".

This repository provides source code to reproduce some of the results of my paper "A Halfedge Refinement Rule for Parallel Catmull-Clark Subdivision". The key contribution of this paper is to provide super simple algorithms to compute Catmull-Clark subdivision in parallel with support for semi-sharp creases. The algorithms are compiled in the C header-only library CatmullClark.h. In addition you will find a direct GLSL port of these algorithms in the glsl/ folder. For various usage examples, see the examples/ folder.

    If the d3d device doesn't support raytracing, the program will crash with an access violation instead of showing an alert

    The check if the d3d.device is nullptr or not is done inside the for loop in CreateDevice. If it's placed after the iteration of adapters, the check will be carried out if there is not device with raytracing support.

  • Textures have black borders.

    Textures have black borders.

    First of all, this project is excellent, very easy to follow and perfectly understandable.

    I've been scratching my head about a few things in the rendered image and how I don't see these in my version. Notice in the screenshot I captured from the application, the area where the texture is supposed to wrap at its border, there is a black edge. This is mostly noticeable on the carpet in the image but also at all the edges of the tiles on the floor and walls. image Outputting "material.baseColor" of the primary hit reveals that source of the issue is the texture or the sampler. Viewing this model in my own application and other gLTF viewers, this is not the case. I believe this issue is caused by the padding of the texture data because of block compression as the texture dimensions are not divisible by 4.

  • InstanceID is 24 bit total, not 32, this could cause issues with large scenes duo to packing

    InstanceID is 24 bit total, not 32, this could cause issues with large scenes duo to packing

    Hello, I was reading preprint of the book(RT Gems II, Chapter 14), and there's a mistake about InstanceID variable, as DXR spec says, it's 24 bit total, but bindless indices are store in the upper and lower 16 bits, this could cause issues if there will be more than 256 unique geometries(you have only 8 bits for upper indices), maybe you can split it 12/12 bits to solve this issue. Hope this will help.

    P.S. Here's the link to DXR spec reference https://microsoft.github.io/DirectX-Specs/d3d/Raytracing.html#instanceid

    Failed to create state object

    I got an error of "Failed to create state object", the return value by "d3d.device->CreateStateObject" indicates that "E_INVALIDARG One or more arguments are invalid."

    But I just went through the code and it all looks fine (debug layer doesn't report any error) and I have no problem running the IntroToDXR. Could you give me a hint about what could be problem?

    I have a GTX 1070 with driver version 471.11, Windows SDK version 10.0.19041.0.
