1. **Add Spatial Entities**Inside your project, click **“Add Object”** to begin adding spatial entities. VoxelSpace supports a wide range of input formats:
- **Point Clouds** - **Meshes (OBJ/FBX)** - **Block Models** - **Ortho-Imagery**
2. **Process Your Raw Data**Once your raw data is in the system, VoxelSpace lets you convert it into optimized formats for analysis and visualization. These include:
- **Indexed Mesh** - **Indexed Point Cloud** - **Voxel Terrain** - **Voxel Block Model** - **Voxelized Mesh** - **Ortho Voxel Terrain**
Choose the format that fits your use case—whether it's simulation, comparison, or rendering. 3. **Create a View**Views are where VoxelSpace truly shines. With a **View**, you can combine multiple datasets into a 3D scene, configure visual styles, explore cross-sections, and share insights with your team. Views are collaborative, reusable, and can be saved or shared across your organization.
# Point Cloud (Raw Data) A **Point Cloud** entity stores raw spatial data collected from sources such as LiDAR or photogrammetry. Uploading point clouds into VoxelSpace is the first step toward visualizing and processing high-resolution terrain or structure data. Upload raw LiDAR or scanned data as a point cloud. The system accepts LAS, LAZ, ASCII, or ZIP formats. → *Used for spatial analysis, terrain generation, and modeling.*
---
**Uploading a Point Cloud** 1. Navigate to the **Catalog** section and select the project where you want to upload the point cloud. 2. Click the **“Add Object”** button. 3.
