christophejeudy Posted February 2, 2020 Share Posted February 2, 2020 Hello, I'v been struggling for quite a while with this. Does anyone know if there is a way to convert a lidar point cloud data to polygon mesh? I have tried the particle fluid surface but It is taking for ever, not sure if I should keep waiting. I've seen these beautiful images (all made with Lidar data) and would like to reach the same level of details. All the best ! Chris Quote Link to comment Share on other sites More sharing options...
flcc Posted February 2, 2020 Share Posted February 2, 2020 (edited) Try Alicevision. You must install Game Development Toolset first. It's a free open source photogrametry plug-in developped by mikros image (As a French guy, you've got to know them https://www.sidefx.com/tutorials/alicevision-plugin/ Don't try it, but having to do some meshing sometime ago, I don't find ideal solution. Better results I get was from : vdbfromparticle-> vdbreshape->vdbsmooth->vdbconvert. I wasn't aware of the Alice solution. If you try it, let us know if it works well, I'm interested.

konstantin magnus Posted February 2, 2020 Share Posted February 2, 2020 On a rather low resolution grid you could transfer the point clouds height coordinates with the nearpoint()-function. To interpolate heights smoothly while making the grid flow exactly through the points, try this: PC_to_grid.hipnc Quote Link to comment Share on other sites More sharing options...
