Unreal Engine to visualize massive point cloud (plot and interaction, zoom, rotation and such)

12 visualizaciones (últimos 30 días)
Hello, i'm dealing with point cloud of millions of points, so my tools are not able to work with them. Before changing scripting language, I'd like to know if anyone has experience using Unreal Engine with MATLAB to plot and interact with point cloud (zoom, 3d rotation and such). I found some pages related to simulink but I don't have it (i don't need it for my current work). Thank you in advance

As per my understanding, you want to plot a large data set in MATLAB and want to interact with it using features like Zoom In, Zoom Out etc.
You can follow the documentation link here to plot a scatter plot for your large data set.
You can interact directly with charts by scrolling to zoom and drag to rotate in 3D.

Hello, thank you for the reply. Scatter_LDS seems to plot points with only X and Y values or am I missing something? I'm dealing with point clouds (3D) and lidar kind of data. Currently I'm using pcshow and also tried pcviewer (from Matlab 2023) but they are too slow (10 millions are the bare minimum number of points I deal with). I tried octree technique to reduce the number of points to currently visualize but I can't solve the plot performance (map interactions)

Hi Veronica, What platform (OS and hardware) were you using when you tried pcviewer? MATLAB 2023b has some optimizations when loading and interacting with large point clouds, in pcviewer. If possible, you can give this a try.
