3D Survey Collection (3DSC)

3D survey Collection is an open source (GPL3) add-on for Blender 3D, coded in Python, that simplifies the process of transforming large architectural complexes or archaeological sites datasets, acquired with laser scanner or photogrammetry, into reusable assets for online/offline publication in virtual museums or applied games. 

The interaction of this tool with heterogeneous data, coming from optical sensors, will make it possible to obtain an immediate characterisation of materials, increasing the quality and visual fidelity of the digital asset representing the cultural heritage.

3DSC allows to: 

• import/export 2D, 3D objects and cameras

• segment objects in tiles

• create and manage objects with Level Of Details (LODs)

• edit color and texture

Release Notes for 3D Survey Collection v1.6.1

New Features:

• Circumcenter Tool: A new tool that allows you to extract circumferences from three designated points on a mesh. This is particularly useful for reconstructing circular and curved elements such as columns and apses from fragmentary data.

• Quick Utils – Flip X and Y Command: Added a function that enables you to invert the X and Y coordinates of selected elements. This is crucial when importing data from total stations where the X and Y axes are swapped. This adjustment can now be made easily within the LOD Manager.

Improvements:

• Direct Mesh Import in LOD Manager: The LOD Manager now supports direct mesh imports, instead of importing objects. This allows local objects to be attributed with specific values, such as chronology, using the Extended Matrix Tool. This enhancement also enables objects with linked levels of detail (LOD) to be repositioned to preferred coordinates, rather than being fixed at 0,0,0.

Reactivated and Enhanced Features:

• Color Correction Node Reactivation: The Color Correction node has been reactivated. This tool is particularly effective on models created using photogrammetry. It is recommended to apply color correction before creating levels of detail (LOD) or, alternatively, to recalculate the LOD after applying color correction.

• Shifting System Improvements: The Shifting function now allows external loading and saving of Shift.txt files. Additionally, it can synchronize with the Blender GIS add-on, ensuring better alignment and geographic positioning of your 3D data.
