This presents unique challenges for high-fidelity interactive solutions that must be quick to set up, efficient to run in real-time on consumer hardware, and work well, not only on human characters, but also on fantastical and heavily stylized ones. We present Interactive Facial Animation (IFA), a novel approach to augment facial animation rigs with shell simulation and contact without requiring anatomical priors or artist intervention. Our method uses an efficient shell model that tracks the output of a face rig in real-time and incorporates realistic contact. By designing our shell model to be differentiable, we can use inverse simulation to reconstruct realistic non-uniform stiffness that captures both stiff (ears, nose) and soft (cheeks, lips) areas, based on the rig’s deformation space. The reconstruction process imposes hard limits on acceptable errors, which ensures that IFA preserves the resolution and expressiveness of the source material, a common shortcoming in many face simulation pipelines. With performance in mind, we demonstrate IFA using a variant of the Fast Mass-Springs method. However, the presented concept can be realized with any differentiable physics solver that provides reliable convergence. We showcase our method in four different character rigs, achieving simulation update runtimes between 0.39 and 1.27 milliseconds (787-2564 FPS) on a single CPU thread. Unlike existing methods that require lengthy preparation times, our pipeline can be ready to use within minutes, also on the CPU.","PeriodicalId":74536,"journal":{"name":"Proceedings of the ACM on computer graphics and interactive techniques","volume":"8 4","pages":"1-21"},"PeriodicalIF":0.0,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147919149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Common practice in the industry is to provide a pre-made selection of distinct garment sizes such as small, medium and large. While these may cater to certain groups of individuals that fall within this distribution, they often exclude large sections of the population. In contrast, individually tailored clothing offers a solution to obtain custom-fit garments that are tailored to each individual. However, manual tailoring is time-consuming and requires specialized knowledge, prohibiting the approach from being applied to produce fitted clothing at scale. To address this challenge, we propose a novel method leveraging differentiable simulation for refitting and draping 3D garments and their corresponding 2D pattern panels onto a new body shape. This enables a workflow where garments only need to be designed once, in a single size, and they can be automatically refitted to support numerous body size and shape variations. Our method enables downstream applications, where our optimized 3D drape can be directly ingested into game engines or other applications. Our 2D sewing patterns allow for accurate physics-based simulations and enables manufacturing clothing for the real world.","PeriodicalId":74536,"journal":{"name":"Proceedings of the ACM on computer graphics and interactive techniques","volume":"8 4","pages":"1-17"},"PeriodicalIF":0.0,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147903323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing reinforcement learning approaches often struggle to efficiently acquire these diverse motion skills from scratch, leading to slow convergence or suboptimal policies. We observed that the motor skills of distinct body parts exhibit a certain level of independence. This suggests the potential advantage of independently pretraining specific dexterous limbs prior to their integration in full-body motion tasks. Inspired by this, we present Part-wise Heterogeneous Agents (PHA) , a cooperative multi-agent reinforcement learning approach where body parts are treated as independent agents, allowing for specialized skill acquisition and cooperative execution of complex full-body tasks. Furthermore, our method enables the pretraining of fine motor skills, such as gripping a bar or grabbing a climbing hold, before integrating them with other body parts for complex whole-body coordination, thus introducing part-wise Reusable Policy Priors . We tested our technique on challenging tasks such as rope climbing, rock bouldering and traversing a horizontal ladder. Our approach not only accelerates convergence, but also improves overall policy quality, achieving motion tasks that single-agent approaches struggle to solve. Our results also demonstrate adaptability, enabling Reusable Policy Priors to adjust their policies to successfully perform complex tasks in scenarios not seen during training.","PeriodicalId":74536,"journal":{"name":"Proceedings of the ACM on computer graphics and interactive techniques","volume":"8 4","pages":"1-22"},"PeriodicalIF":0.0,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147891327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Complex geometric structures are represented in a voxel grid for the efficient evaluation of volumetric effects. In addition, a signed distance field is introduced to query the surface information required to compute the insulating effect caused by the char layer. Non-charring materials such as acrylic glass or non-combustible materials such as stone can also be modeled in the simulator. Adaptive data structures are utilized to enable memory-efficient computations within our multiresolution approach. The simulator is qualitatively validated by showcasing the numerical simulation of a variety of scenes covering different kinds of structural configurations and materials. Two-way coupling of our combustion simulator and position-based dynamics is demonstrated capturing characteristic mechanical deformations caused by the combustion process. The volumetric combustion process of wooden structures is further quantitatively assessed by comparing our simulated results to sub-surface measurements of a real-world combustion experiment.","PeriodicalId":74536,"journal":{"name":"Proceedings of the ACM on computer graphics and interactive techniques","volume":"8 4","pages":"1-19"},"PeriodicalIF":0.0,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://dl.acm.org/doi/pdf/10.1145/3747855","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147911339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ball joint orientation can be decomposed, non-uniquely, into swing and twist components. In modeling with ball joints, it can be advantageous to include limit constraints on the swing, twist, or both. While many physics engines include such limit constraints, we have found that twist limit constraints, when present, are lacking in robustness, typically due to unhandled singularities in commonly employed swing-twist decompositions, where the twist state is undefined. In this paper, we introduce two novel, robust models of the ball joint twist limit constraint. The first utilizes the Euler angle decomposition of the orientation, which has two singularity points. To robustly handle the twist limit constraint, we propose a novel treatment at singularities based on the physical behavior of a three-hinge system. Thus, our model significantly reduces the dramatic motion that can occur around the singularities, eliminating the need to directly avoid them. Second, we introduce an alternative incremental model that avoids singularities altogether during simulations. In this model, the twist is quantified by integrating the instantaneous twist velocity in time, ensuring that the singularity shifts from one time step to the next and remains far from the current state. We investigate the properties of both proposed models. We demonstrate that both models offer robust and practical solutions to common issues encountered in constraining the motion of ball joints.","PeriodicalId":74536,"journal":{"name":"Proceedings of the ACM on computer graphics and interactive techniques","volume":"8 4","pages":"1-25"},"PeriodicalIF":0.0,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147910503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the controller is a deep reinforcement learning policy, the output of several controllers can be combined to enhance controller robustness and synthesize new motion variations. However, this requires evaluating several policies at each timestep and combining their outputs, which can be computationally costly. In this work, we propose an alternative approach that combines individual controllers using linear interpolation of network parameters, thereby requiring only a single policy evaluation per timestep. Our method employs a graph-based weight regularization strategy to ensure that similar motions generate similar policy weights during training. We show that this technique produces visually indistinguishable outcomes compared to blending controller outputs, and that the approach easily integrates new control policies without retraining existing ones. We further demonstrate that interpolating or perturbing individual layers results in novel variations of the internal motion pattern that cannot be easily achieved by operating on the actions. This opens a path toward improved variability in controller networks by manipulating their weights. Several compelling use cases demonstrate the benefits of our approach, including interactive control and synthesizing motion variations.","PeriodicalId":74536,"journal":{"name":"Proceedings of the ACM on computer graphics and interactive techniques","volume":"8 4","pages":"1-22"},"PeriodicalIF":0.0,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://dl.acm.org/doi/pdf/10.1145/3747863","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147916538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
