Merging Multiple Tile OBJ Files using CloudCompare (ContextCapture Tip)

Hello, welcome to my UA-cam channel! In today's video, I'll show you how to merge multiple tile OBJ files into a single OBJ file using CloudCompare. This method is particularly useful when you have a large number of tile OBJ files and need to combine them efficiently. We'll also touch upon ContextCapture's ability to divide large models into smaller tiles and the challenge of merging the resulting OBJ files. Let's get started!"
Step 1: ContextCapture's Tile Division
"First, let's talk about ContextCapture. If you encountered low memory problems while 3D modeling with ContextCapture, you may have already discovered its ability to divide large models into smaller tiles. By dividing the model into tiles, ContextCapture can help overcome RAM limitations, making it easier to process and work with large datasets."
Step 2: Exporting Tile OBJ Files from ContextCapture
"When exporting your model from ContextCapture, you might have chosen the tile division option. This would have generated a set of separate tile OBJ files, each representing a specific region of the model. However, ContextCapture does not provide a built-in option to merge these OBJ files back into a single file."
Step 3: Opening CloudCompare
"To merge the tile OBJ files, we'll be using CloudCompare. CloudCompare is a powerful point cloud and 3D modeling software that supports the OBJ file format."
Step 4: Importing Tile OBJ Files to CloudCompare
"Inside CloudCompare, locate the main folder containing your tile OBJ files. Using the Windows search bar within the main folder, search for '.obj' to easily locate and select all the OBJ files. With the files selected, drag and drop them into the CloudCompare workspace."
Step 5: Merging OBJ Files
"After the tile OBJ files are loaded into CloudCompare, you should see each tile as a separate object in the software. To merge them, go to the 'Edit' menu and choose the 'Merge Selected' option. This will combine all the selected objects into a single object."
Step 6: Exporting as a Single OBJ File
"Once the merge is complete, go to the 'File' menu and select 'Save As.' Choose the desired location and provide a name for your merged OBJ file. Make sure to select the OBJ file format for the export."
Conclusion:
"By combining the capabilities of ContextCapture's tile division and CloudCompare's merging functionality, you can efficiently work with large models while maintaining a manageable memory load.

this method preserve texture? sometimes merge OBJ files generates fails in textures...thank you

[@rockbench]

If the texture file's location address and the image format (jpeg or jpg or png ...) are exactly the same as the address in the .mtl file, each .obj tile can have its texture file.
