OP2GS: Object-Aware 3D Gaussian Splatting with Dual-Opacity Primitives
Guiyu Liu, Niklas Vaara, Janne Mustaniemi +2
3D Gaussian Splatting (3DGS) provides an explicit and efficient scene representation, but its primitives lack inherent object-level identity, hindering downstream tasks such as ope…

Differentiable Ray Tracing with Gaussians for Unified Radio Propagation Simulation and View Synthesis
Niklas Vaara, Lam Huynh, Pekka Sangi +2
Explicit neural representations such as 3D Gaussian Splatting (3DGS) enable high-fidelity and real-time novel view synthesis, yet optimize for alpha-composited optical appearance r…

Differentiable High-Performance Ray Tracing-Based Simulation of Radio Propagation with Point Clouds
Niklas Vaara, Pekka Sangi, Miguel Bordallo López +1
Ray tracing is a widely used deterministic method for radio propagation simulations, capable of producing physically accurate multipath components. The accuracy depends on the qual…
