Simulation News
The latest Simulation coverage curated for game developers.
GameFromScratch reports that RimWorld 1.7 marks a major engine shift: Ludeon has moved the long-running colony sim off Unity and onto its own Waylith Engine. For developers, that raises immediate …
XBox Wire says Microsoft Flight Simulator has added the National Championship Air Races alongside a new aircraft pack today. For developers, it’s another reminder of how the sim keeps expanding …
arXiv cs.GR details a hierarchical graph neural network that predicts probabilistic power flow across changing grid topologies. The model keeps accuracy under unseen N-1 and N-2 contingencies, with lower angle …
Box2D details a contact recycling technique that can make rigid-body contact generation nearly free in stable stacks and resting pairs. The approach reuses cached manifolds when relative motion stays below …
ACM Graphics details a new time-integration method for elastodynamic contact that lets simulation energy be controlled more directly. For game teams wrestling with soft-body stability, this points toward fewer explosive …
arXiv cs.GR details RiCo, a neural rigid-body simulator that focuses contact reasoning on nearby surfaces instead of whole-scene pairwise interactions. The model cuts 100-frame position error by 31-35% and orientation …
arXiv cs.GR details JamTet, a GPU-parallel sphere-packing mesher for Lagrangian mesh morphing that keeps interior-node identity through large shape changes. The method aims to avoid the inversion and correspondence loss …
arXiv cs.GR details StableGrasp, a single-image hand-grasp reconstruction method that aims for physical stability, not just plausible pose. The system separates visual hand geometry from the control target, then optimizes …
arXiv cs.GR details UltraDiff, a differentiable ray-tracing framework that brings gradient-based optimization to ultrasound shape reconstruction. The method treats echoes as time-of-flight events, then backpropagates through a Monte Carlo forward …
arXiv cs.GR details PhysLDM, a latent-diffusion approach for high-fidelity deformable simulation that aims to make volumetric physics both cheaper and more stable. The paper pairs a spatiotemporal VAE with diffusion …
arXiv cs.GR details a wildfire-monitoring VLM that turns 2D simulations into labeled video episodes, then uses them as memory for training-free reporting. The system hit 51.5% exact four-tag accuracy on …
arXiv cs.GR details 4DCodeBench, a benchmark that tests whether agents can turn video into executable graphics code for dynamic scenes. The setup targets deformation, fluids, and fracture, and the early …
arXiv cs.GR details InterEvolve, a test-time method that evolves reward programs so humanoid controllers can tackle new loco-manipulation tasks without retraining. The system pairs an object-aware FB model with LLM-guided …
arXiv cs.GR details a spline reconstruction method that keeps exact CAD geometry while allowing local knot insertion, degree elevation, and basis edits. The catch is continuity: the new hybrid operator …
arXiv cs.GR details a design tool that can rapidly test whether 3D obstacle-course layouts are solvable under designer-set constraints. It pairs GPU-accelerated simulation with search and RL guidance, giving level …
arXiv cs.GR details Text2Sim, a pipeline that turns a text prompt into an editable physics simulation. Built on Genesis, it uses a planner, specialist writers, asset tools, and a critic …
arXiv cs.GR details CoDimRecon, an agentic pipeline for turning multi-view RGB into sim-ready 3D scenes with rigid, articulated, and deformable assets. The system targets a long-standing gap for deformables, reconstructing …
XBox Wire says Used Cars Simulator is out now on Xbox Series X|S, and the loop is all about inspecting, repairing, and flipping beat-up vehicles for profit. The game mixes …
GamesIndustry.biz reports that Trophy Games has bought Playrion from Paradox Interactive for €2.25 million upfront plus a three-year earn-out. The 30-person studio behind Airport Simulator: First Class will help Trophy …
arXiv cs.GR details TapeSim, a tape-dispensing simulator that keeps most wound material rigid while concentrating deformation near the unwind point. For robotics teams, the payoff is faster physics steps without …
