**INTRODUCTION**

SiEGA is a scalable simulation environment for geospatial assets, designed for visualizing, analyzing, and simulating the real world in 3D. It combines reality capture, spatial intelligence, and immersive visualization into one unified platform, empowering organizations to explore complex environments, integrate high-fidelity datasets, and transform captured reality into informed decisions. The AERO AI ecosystem includes purpose-built products for reconstruction, visualization, immersion and access:

**3DINT Engine** - Windows desktop reconstruction and spatial intelligence. Turn drone imagery, LiDAR and laser scans into point clouds, textured meshes, Gaussian splats, orthomosaics and elevation models on your workstation. Review quality and prepare 3D Tiles for delivery to SiEGA or Cesium ion. See the [3DINT Engine documentation](/3dint-engine/overview.md) for installation, project setup, processing and delivery workflows.

**SiEGA Web** - Browser-based geospatial visualization and collaboration. Access and interact with geospatial data from any browser, designed for stakeholder review, fast insight sharing, and lightweight analysis without installing desktop software.

**SiEGA Desktop** - High-performance desktop visualization and immersive digital twins. Powered by the Unreal Engine and Cesium for Unreal, SiEGA Desktop supports complex scenes, large datasets, and advanced 3D simulation workflows that require deeper interaction with geospatial environments.

**SiEGA Studio Delivery** - Custom geospatial applications and enterprise solutions. AERO AI's custom delivery model for organizations requiring tailored digital twins, bespoke workflows, and specialized deployments.
