iTwin Capture Modeler, Bentley Systems 3D reality modeling software, transforms simple photographs or clouds of LiDAR points into 3D reality meshes, orthomosaic and Gaussian Splats ready for engineering. This article details its flagship functionality: the generation of high-precision 3D reality data, now enriched with the Gaussian Splatting.
iTwin Capture Modeler is Bentley Systems' reality modelling application, designed to prepare, organize and pilot your reality capture projects. It allows you to import photographs or clouds of LiDAR points, then to entrust their processing to the iTwin Capture Engine (locally or via iTwin Capture Cloud Services) in order to produce faithful digital twins of your existing infrastructure: buildings, art works, industrial sites, construction sites or entire territories. Formerly known as ContextCapture, iTwin Capture Modeler is now part of Bentley's iTwin ecosystem and is the starting point for any Bentley project. reality modelling : from field survey to integration into a digital twin that can be used in engineering.The iTwin Capture Modeler interface allows to organize a capture project before processing.
Focus functionality: generating 3D reality meshes and Gaussian Splats
The central feature of the iTwin Capture Modeler is to convert raw data (photos, drone images, LiDAR scans) into usable 3D deliverables. It's the engine. iTwin Capture Engine which executes this processing, locally for speed and confidentiality of data, or in the cloud via iTwin Capture Cloud Services to absorb the largest projects.
From point cloud to usable 3D model
From the imported data, the software automatically calculates multi-resolution reality meshes, digital surface models, true orthosaic (true ortho) or classified point clouds. Accuracy adjusts at project level: from a simple work to the modelling of an entire city.
The Gaussian Splatting Novelty
Bentley Systems has integrated the Gaussian Splatting at iTwin Capture Modeler: this rendering technique restores the fine details (cables, antennas, reflective elements) with an unprecedented realism while keeping outputs ready for engineering. The teams thus have a photorealistic rendering without sacrificing the technical exploitability of the model.
Local or cloud processing, at any scale
Thanks to the execution of several engines in parallel, iTwin Capture Modeler accelerates the delivery of large projects and allows to move from a single site to a city-scale project without disruption.Classification and extraction of elements from captured reality data.

Case of practical use
Sur le terrain, cette fonctionnalité de génération de réalité 3D sert aussi bien l’inspection d’ouvrages d’art que la gestion patrimoniale ou le suivi de chantier. Un relevé par drone ou scanner LiDAR suffit à produire un modèle 3D exploitable pour la maintenance, la planification de travaux ou l’intégration dans une maquette BIM.Modélisation 3D de ponts et structures pour la gestion et la maintenance d’ouvrages.

Frequently Asked Questions
iTwin Capture Modeler est-il gratuit ?
La préparation et l’organisation des projets sont gratuites avec iTwin Capture Modeler Flex. Le traitement des données en maillages, Gaussian Splats ou nuages de points nécessite en revanche l’iTwin Capture Engine ou un abonnement iTwin Capture Cloud Services.
Quelle est la différence entre iTwin Capture Modeler et ContextCapture ?
iTwin Capture Modeler est l’évolution de ContextCapture au sein de l’écosystème iTwin de Bentley Systems : mêmes fondations de modélisation de réalité, enrichies de nouvelles capacités comme le Gaussian Splatting et une intégration cloud renforcée.
Quels formats de données iTwin Capture Modeler peut-il traiter ?
Le logiciel accepte les photographies (prises au sol ou par drone) ainsi que les nuages de points LiDAR, et produit en sortie des maillages 3D, orthomosaïques, modèles numériques de surface, nuages de points classifiés et Gaussian Splats.
