MESHLAB QUADRIC EDGE COLLAPSE DECIMATION SOFTWARE

Suitable for smaller “open” models as electrical tower. Surface Reconstruction: VGC: Single thread in the most part, slower.Creates loose pointcloud with bunch of holes. Surface Reconstruction: Ball Pivoting: Single thread, slow.Example of the set values is in the image below. The RAM demands increases faster than linear. The higher the number, the more detailed is the model. I have found useful to increase the Reconstruction Depth. It usually works well for closed environemnts as buildings. Surface Reconstruction: Screened Poission: this methos is useful for most cases.AMD processors are much faster on Ubuntu to create the mesh: It takes much longer time for Intel to do the same task.

The general rule: Better to create a huge model and simplify it than create a small model right away.The ideal number of vertices is 6–10 milions. The input pointcloud has to be simplified to be able to mesh it.If you can provide 64 GB RAM, even better! Mesh computing requires a huge amount of RAM! It is recommended to have at least 32 GB RAM with some backup swap.We are using manily two methods to create a mesh from a pointcloud. Point format as X Y Z Reflectance R G B.Run Matrix: Freeze Current Matrix function to apply the transformation on current file.It keeps the transformation from the original position in the readable XML format simple savefile. If you are stasified with the adjustement, firstly save the Meshlab project.Follow the instruction to adjust the position of the pointcloud.Show the coordinate system with the Draw XYZ axes in world coordinates icon.The best option is to align the coordinate system before exporting the data from Leica as explained here.It is useful to do ASAP at the beginning of the process. IMPORTANT: Adjust the PointCloud coordinate system.Make sure to have the layer you want to clean active (in blue color)!.

Use the tool Select Faces/Vertices inside polyline area to clean the pointcloud.

Check Keep unreferenced vertices and click Apply. Click on the one of the layer with Right mouse button -> Flatten Visible Layers.

At the end, merge all imported layers into one.

Meshlab has a new setting in the Settings->Tools for each file format.

Run the Meshlab from the commandline to be able to watch the events.ĭescribe steps to import.

DO NOT FORGET TO SAVE REGULARLY YOUR WORK! MESHLAB LIKES TO CRASH.

IMMEDIATE_MODE_RENDERING: only CPU, much slower.

BO_RENDERING (Buffer Object Rendering): everything is running on the GPU - fast.

On left down panel, there is information about FPS and rendering mode:

Restart MeshLab and open some large model.

Set it according to our GPU memory, e.g., for 4000 MB RAM, set slightly lower to 3500 MB.

Scroll down to maxGPUMemDedicatedTechnology.

Use the Linux AppImage from Meshlab official website.

Also allows to simply process pointclouds.

Software for general work with meshes and texturing. This site uses Just the Docs, a documentation theme for Jekyll. Commanding the robot relative to its position.
