SpatialGS: Relative Spatial Regularization in Gaussian Splatting for Layout-guided text-to-3D generation

Layout-guided text-to-3D generation has significantly advanced the controllable synthesis of multi-object scenes. However, existing methods still struggle to maintain consistent and precise spatial relationships, frequently exhibiting inaccurate relative positions and ambiguous object orientations. To bridge this gap,...

BridgeAfford: Bridging Query-Target Gap for Generalizable 3D Affordance Grounding

Cross-object alignment among geometrically similar interaction regions during training enables structures on unseen objects that resemble previously observed ones to produce representations similar to those learned during training, facilitating target-region recognition.

GeoLatent: Geometry-Guided Latent Structuring with Routed Optimization for 3D Reasoning

Despite progress in vision-language models, 3D spatial reasoning from 2D images remains challenging. Text-based methods describe intermediate geometry with discrete tokens, limiting fidelity for continuous spatial relations. Continuous latents offer richer representations, but a single latent type does not explicitly s...

Terminal Agents: A Survey of AI Agents in Command-Line Environments

This survey establishes workload-level boundaries and connects system architecture, competence acquisition, and evaluation through a seven-dimensional terminal competence profile, and provides a unified basis for studying terminal-mediated agency across software engineering and emerging application domains.
