2019年3月25日 · While the fallback layer interface tries to stay faithful to the original DXR API, there are several points of divergence. The primary difference is DXR’s requirement of reading pointers in shaders, primarily at ray dispatch when traversing from a top-level acceleration structure to a bottom-level acceleration structure.

2025年1月24日 · This collection of samples act as an introduction to DirectX Raytracing (DXR). The samples are divided into tutorials and advanced samples. Each tutorial sample introduces a few new DXR concepts. Advanced samples demonstrate more complex techniques and applications of raytracing. Requirements. GPU and driver with support for DirectX 12 Ultimate

These two posts showcase basic intergration of ray tracing within an existing DirectX sample. The goal of this tutorial is to add raytracing to an existing program, so that the raytracing and raster paths share the same geometry buffers. Step-by-step, we will go through the major building blocks required to do raytracing.

DirectX Raytracing (DXR) is a feature introduced in Microsoft 's DirectX 12 that implements ray tracing, for video graphic rendering. DXR was released with the Windows 10 October update (version 1809) on October 10, 2018.

2018年3月19日 · PIX on Windows supports capturing and analyzing frames built using DXR to help developers understand how DXR interacts with the hardware. Developers can inspect API calls, view pipeline resources that contribute to the raytracing work, see contents of state objects, and visualize acceleration structures.

We first need to modify the root signature of the hit shader to use a constant buffer passed as a root parameter. Contrary to the buffers passed on the heap, root parameters can be passed per instance.

PIX on Windows includes support for the final DirectX Raytracing (DXR) that’s part of the Windows 10 October 2018 Update (a.k.a. “RS5”). This allows you to debug your raytracing code by capturing and analyzing your DXR applications with the same tools that you would use to capture and analyze your other D3D12 applications.

2019年11月6日 · Inline raytracing in shaders starts with instantiating a RayQuery object as a local variable, acting as a state machine for ray query with a relatively large state footprint. The shader interacts with the RayQuery object’s methods to advance the query through an acceleration structure and query traversal information.

2024年10月10日 · DxR 是一款专为 Unity 设计的包，旨在加速沉浸式 数据可视化 在增强现实 (AR)、混合现实 (MR)及虚拟现实 (VR) (统称XR)中的原型设计。 通过直观的界面或高级编程接口，它允许设计师灵活地将数据属性映射至Unity游戏对象的视觉表现。 1. 项目目录结构及介绍. DxR的仓库遵循清晰的组织结构，便于开发者快速上手： ├── Assets # Unity资产文件夹，包含核心组件和资源. │ ├── DXR # 主要的DXR包，包括脚本和预制件. │ └── ... ├── docs # 文档 …

DXR is a toolkit for rapidly prototyping Data visualizations in XR (augmented, mixed, and virtual reality). A visualization in DXR is a collection of Unity game objects whose properties...
