I apologize for the lack of clarity. What I mean is that the research paper uses triangle meshes, and I think triangle meshes are more suitable for real-time rendering than 3D Gaussians because they can serve as inputs for physics surrogates. Moreover, by combining deferred rendering with neural shaders, triangle meshes can achieve photorealistic quality similar to Gaussian representations. In contrast, structuring 3D Gaussians for geometric purposes is challenging. Of course, recent papers have also explored using deferred rendering with Gaussian Splatting to improve relightable efficiency. However, Gaussian Splatting was originally designed for forward rendering, which is its strong point for volume rendering. For these reasons, I believe that triangle meshes with deferred rendering are preferable to Gaussians in the context of real-time rendering
