### Operating System Ubuntu 24.04 GPU Information - Model: RTX 4090, RTX 3060 ### Detailed Description Hello, I am successfully working on utilizing 3D Gaussian Splatting (3DGS) derived assets within NVIDIA Omniverse. I have confirmed that I can convert the 3DGS results into a **USDZ file** (using tools like 3DGUT) and import it into Omniverse Kit/Create. My core application goal involves performing **3D Object Detection** (identifying and localizing objects, without classifying the type) directly on the reconstructed scene. My question is as follows: 1. **3D Object Detection on 3DGS:** Is it technically possible to perform **3D Object Detection** operations _directly_ on the imported 3DGS representation (the Gaussian particles/point cloud) within Omniverse, or is the data structure inherently unsuitable for this type of geometric analysis? 2. **Required Extension/Workflow:** If it is possible, what is the recommended **Omniverse Extension** or workflow required to enable real-time 3D object detection on 3DGS data? Does this require converting the 3DGS data into an explicit geometry like a **Mesh** or a dense **PointCloud** beforehand? Any guidance on how to leverage the high-fidelity 3DGS reconstruction for real-time object detection and segmentation tasks in the Omniverse environment would be greatly appreciated. Thank you. ---
