Mesh

The following processing options can be adjusted when enabling the mesh generation:

 
Access:
  • Click Process processing options.
  • On the Menu bar, click Process > Mesh...
 
Important: At the moment, the Mesh cannot be visualized directly in PIX4Dmatic, but it can be uploaded to PIX4Dcloud, for visualization. For more: How to upload or replace results to PIX4Dcloud. Other third-party software can also be used to view the mesh. For example, Windows 3D Viewer, Meshlab, Global Mapper, Rhino, 3ds Max, 3DBuilder, or Autodesk Maya.

Input (Optional)

 
Important: This option is only enabled in project acquired with PIX4Dcatch that contain LiDAR data.

It allows selecting the input point cloud for the Mesh generation. The following options are available:

  • Dense point cloud (default): The point cloud generated from images during the Densify step.
  • Depth point cloud: The point cloud generated from LiDAR depth maps.
  • Depth & dense fusion: The point cloud that present a fusion of the dense and depth point cloud.

Template

This option enables distinguished default parameters for the mesh generation algorithms used for the different types of datasets imported into the software. The following templates are available for the Mesh generation:

  • Aerial (default): Ideal for scenes with larger extent. Typically drone flight size projects that contain oblique or nadir data.
  • PIX4Dcatch: For projects with limited extent. Optimized for hand-held captured data with PIX4DCatch.
  • Thin structures: For projects that capture thin structures, i.e., cables, powerline tower structures, antennas.

Texture size

Texture Size (1024x1024 - 32768x32768 pixels, default 8192x8192 pixels): Parameter used to define the resolution of the texture of the Mesh.

Decimation

Decimation (1.000.000 default): The maximum number of triangles in the final Mesh. The number will depend on the geometry and the size of the project.

 
Note: For projects that are not very large, it may be that the resulting number of triangles is lower than the maximum set up in the options. The maximum will only be reached if the project is large and could create a model with more triangles.

Sky mask

Sky mask utilizes the generated mask during the Densify step to improve the mesh quality. It is enabled by default when the Sky filter option is enabled while running the Densify step.

Note: The Sky mask option can be selected only if the Sky filter option during densification is enabled or has already been processed.
