CloudCompare forum

Ok i see! Unwanted code complexity and ram abuse are not good solutions. I’ve been using my AHK hack to end the segmentation, quit the tool and restarting it automatically for the last two days and it makes a huge difference for me. Right now i’m using it on my professional laptop and have 60 fps co...

Hey! So this simple autohotkey code is a way to automate the end of the selection and restart of the segment tool in order to always get the best performance. #IfWinActive, ahk_exe CloudCompare.exe ; Whenever the active window is CC <!o:: ; Whenever Alt+o is pressed: MouseGetPos, xpos, ypos ; Gets t...

Hey Daniel, i just tried, that's a great improvement! And thanks to your feedback i now understand better what's happening. The visibility array depends on the point of view, that's why it needs to be "uploaded" to the GPU every time the display is updated? Speculative/candid: What if inst...

Hey! Ok i just tried with a ≈4 Mpts cloud on 2.11.3 on our nice processing PC, it's the same, when i wiggle the cloud in the 3d view i get 55 to 60 fps when the segment tool is inactive, 5 to 10 fps when the tool is active and on pause. Also worth mentioning: the GPU and CPU usage only marginally in...

Honestly i'm unsure if it was better before or always like that… I usually work on decent computers so i did not really pay attention to this performance drop before honestly. However on my field work laptop it's pretty obvious. Also worth mentionning, i used to work only in orthographic mode, witho...

Hey there, i noticed that the display performance (FPS) is decreasing a LOT while the segment tool is enabled. On my laptop, with a ≈3 Mpts cloud, the display is perfectly smooth (50 to 60 fps), but when i open the segment tool it drops to ≈ 7 fps on average. I’m here referring to fps while moving t...

Hi there, i’m just quickly reporting after doing many tests on the curvature-dependent SS. It’s a great feature, i love it! However, since the SS value interpolation is linear, that tends to remove too many points on details (or not enough points on flat areas, depending on your input parameters) fo...

Hi Daniel, thanks for your quick reply! It’s ok i still very much enjoy this feature in UI  mode. It makes a lot of sense to only keep dense data in curvier volumes. Before that, i used Meshlab’s quadric edge collapse decimation, but having this integrated in CC saves a lot of time and space. I’ll b...

Hi there, i’m new here, so first of all Thanks a Lot for the efforts over the years and the great software you wrote!! I recently discovered that you can use a SF to scale the spatial subsample target of a cloud. I tried it it the UI, with great results. However, i would like to use it in command li...
