quickly deleting multiple point clouds + manual for 3DForest05?

[Anonymous]

Hey there,

is there some quick way I'm missing to delete multiple point clouds from the project (without closing it and deleting them in the project file and folder). I was thinking about just selecting multiple clouds with shift or ctrl instead of just one at a time.
I want to try different Tree segmentation settings but what do I do with the hundreds of tree point clouds, which I then want to discard?

Furthermore, will there be a manual for 3DForest 05? I'm still unsure about a couple of the input parameters for the tree segmentation as not all of them are explained in the info box in the software.

Another "nice to have" for the next release: An option to save settings to a text file (and maybe also import settings from a test file?). This would make the testing of segmentation parameters much easier.

Hi Hannah,

Closing project and deleting the point clouds manually from project file is the fastest way how to do it for now. Simple way for deleting multiple pointclouds is on our todo list, as well as new User guide for version 0.50 and lot of other functions (database for storing tree parameters, ability to run 3DForest functions from command line with different settings...). Unfortunately we are currently overloaded by work, so it'll take a while. Any help is welcomed :-)

Here is a brief description of new segmentation and its parameters:
1) Point cloud is divided into voxels, parameter Input distance = voxel resolution
2) Compute descriptive (descriptor) value for each voxel, PCA = ratio of three main axis, intensity = average points intensity in voxel, slope = slope of points in voxel.
3) Searching for neighboring voxel with simmilar decriptive value (within the range parameter) to define stem base.
4) Joining other voxels to stem bases up to given distance, multiplication value times input distance

number of elements refers to minimum number of connected voxel to be considered as tree
distance from terrain is minimal distance from ground in which point cloud has to have some points to be considered as tree .

i can suggest aslo another method for deleting - merge all clouds into one and delete only one file after merging.
