lighting rgb&intensity doesn't work

[zedisdead]

Hi
Your support really doesn't work at all. Writing that I have to install latest P4R or update drivers or try a Gotomeeting session and then write me that I have send files but didn't told ya which files this is really unprofessional.
so...
I have Pointools4Rhino2.2-100524 and rhino v4.0 r8 and lighting
rgb&intensity doesn't work
on windows 7 pro
NVIDIA Quadro FX 1800
Intel(R) Core(TM) i5 CPU 750 @ 2.67GHz
4,00 GB ram
DirectX DirectX 10
bios video 62.94.90.00.0d
Any suggestions?
regards

Hi Zed,

I have spoken to the support team and they are waiting for you to send through the POD file. The screenshots you sent suggest that your data may be the problem, so this is why the request has been made.
To date we haven't had any other issues of this sort from this release, so we hope to solve your problem as soon as possible.

To make sure your data has RGB and/or Intensity values use Pointools View or Edit to look at the data. If you could confirm where the data came from (e.g Leica/Faro) and your import process, it will help us to help you.
Also, the lighting option will only work on data that has the lighting 'normal' information stored.

Cheers, Dan

Hi
OK I understand now when you gave me all those informations. I think you could wrote me all this in one mail and that would speed up all your support process. So far I was working on low end graphic card and everything was fine in free version of pontools view. When I changed whole PC to one with quadro fx1800 and installed free pointools view rhino and pontools4rhino it stopped working. So my conclusion was it's some sort of incomapbility of drivers and software, and now I dont' know what it is. The pointclouds are exported from cyclone software.
Is it possible sending small samle scan to see if with all needed data it will work on my PC?

There is some example data on the download page of our website - http://www.pointools.com/download.php

Here are some printsreens. The most important feauture for me now is lighting. How to enable it? It's the same laser scanner and same software cyclone. Screens with old in name are from low end graphic card from old PC. It worked.

Hi Zed

Without the files that you are having a problem with (*.pod files obviously) Pointools can only go on your word and from looking at the screen grabs that you have provided it looks like you might be confused about a few things.

First off if the screen grab ‘alternburg RHINO.jpg’ is from your new PC then you are incorrect when you say that the intensity doesn’t work as it clearly does. It’s a shame that you hadn’t ticked the ‘RGB (Full Colour)’ box as well before taking the screen grab because then it would be clear if the display of RGB was also a real problem.

The screen grab ‘lowend old 2.jpg’ is clearly a different point cloud altogether to that shown in the screen grab ‘alternburg RHINO.jpg’... for a fair comparison it would be better to provide screen grabs of both the old and new computers with the same *.pod file loaded.

I have checked the file ‘altenburg_library_riegl.pod’ and it has no normal information for lighting available. The other sample ‘barn_bit.pod’ provided on the Pointools website does have lighting so I would recommend trying this one for lighting.

It should not be assumed that all Point Clouds have Lighting + Intensity + RGB. Also Lighting cannot just be enabled in Pointools4Rhino it has to be available in the point cloud i.e. it must have normal information for it to work.

Is it possible that the point cloud you have been having problems with in Pointools4Rhino doesn’t have RGB, Intensity or Lighting?

Please can you confirm if the RGB works on the file ‘altenburg_library_riegl.pod’ and the lighting on ‘barn_bit.pod’?

Hi
I've checked files altenburg_library_riegl.pod and barn_bit.pod and in altenburg_library_riegl.pod RGB is working and the second one I checked it in Pointools view and lighting works better than in P4R. But in Pointools4rhino it act strange because it shows only the specular area and rest is black. And I forgot to mention that size of point in P4R works only in two sizes the small one and the bigest one. In Pointools view the size of points works fine.

Hi Zed

Looks like there was never a problem with Pointools4Rhino’s RGB, Lighting or Intensity.

The lighting in Pointools View Pro will look different to Pointools4Rhino if the settings are different.

In my screen grabs you can see that the lighting is quite comparable between Pointools4Rhino & Pointools Edit (Edit works the same as View Pro for lighting).

Also RGB looks much better if you switch off Planar Shading & Intensity (especially when both are set to Hue Ramps).

Hi
Ok, looks like there never was a problem. But is there a way to add normals to point cloud if it has no normals information. In yours POD creator is a option to import normals. Is a way to generate normals for pointclouds?
Regards

[Dan]

Zed,

You'll notice that the generate normals option is only available with certain types of data on import. This is because it relies on certain information within the file being present. Normals are calculated using the position of the points in relation to the scanner that collected them. In an ascii file such as XYZ or TXT, it has no such information. However in an FLS file or other LS manufacurer format you may well find that this information is present and it will allow you to generate normals.
