Despite the advancements in models like Atlas, 3D representations like Gaussian splats and meshes continue to hold value for specific applications, particularly real-time use on embedded devices and integration into existing industry workflows. Justin Johnson noted their utility for client-side rendering on mobile or VR devices and for meeting users where they are in established pipelines.
“And you got to use the right tool for the job, right? Like if you're working on something like VFX, then the ultimate output is a 2D image. Um, and maybe that's all you need.”
“But for other applications, especially real-time applications on embedded devices like I think Gaussians and other explicit 3D representations still have their place.”
“So something like a Gaussian or a mesh, um, is really useful for client-side rendering, um, especially on mobile or VR devices. Um, and also really useful for integrating with existing workflows and pipelines.”
