Re: Scaling the Color Scale

I have found the bug (and hopefully fixed it, you can try with the new 2.12.alpha version online). And to create the color ramp you want (with the trick I suggest), with fixed color, you have to start with an absolute color scale and then: 1) reduce it to 2 steps 2) make sure the steps are above th...

Re: Scaling the Color Scale

So the crash is definitely not normal! Which version are you using? Do you have a reproducible way to make CC crash? And then, the gradient is the default mode. You have to trick CC by defining two steps very close to each other (like 1 and 1.00001) at each color changing point to visually achieve ...

And how we can change the color scale in absolute ? I mean absolute color difference(red, then yellow, then black, etc) instead of color gradient

Re: Scaling the Color Scale

To do this you have to create a custom 'absolute' color ramp: http://www.cloudcompare.org/doc/wiki/index.php?title=Scalar_fields%5CColor_Scales_Manager An absolute color scale uses 'absolute' steps, i.e. the colors are only displayed between the values you specify. And you can also set custom 'labe...

Color Scales Manager

Hi everyone.

I am playing with CC these days and wondering if I can customize my C2M distance by setting a threshold/interval.
Say a interval like this :
>1cm,1cm,0cm,-1cm,<-1cm

Thanks!

Re: Project point clouds into 2D local coordinate system

Thank you for your reply! How about gridding the point cloud with fix size, say 1m * 1m?

Project point clouds into 2D local coordinate system

Hi everyone,

I am working on a project which require projecting a 3D point cloud into a 2D local coordinate system (no raster), is there any ways to realize this?
Also, can I grid the projected 2D point cloud into a certain size of grid? Is it accomplish by octree?

Thanks!
Fuji

Re: Regular gridding of point cloud

Well, on the C++ side the plane fitting and the sectioning functions from CloudCompare were used, specifically I used the ccClippingBoxTool::ExtractSlicesAndContours() function to section the input cloud(s) into the grid I wanted, and then fit planes to each sectioned cloud with the same process us...

Re: Regular gridding of point cloud

There is a way for sure I had to do something similar in a proprietary plugin, so I can't share :( But I can say that what your describing can definitely be automated, if you can code I can offer some guidance. Hi Wargod, Yes. I am on a trial and error stage in programming my project in python(or e...
