Shape Extraction for AutoCAD

[#1]

I did not see a catagory for this, so I figured this was the closest related area.

Autodesk: Why doesnt 3D max use the .pcg file for 3dmax? What is this .ptsb and why doesnt the ptsb converter work? It crashed out when we exported a pts file from cyclone, and from LaserControl.

ok, so after a little more research, to anyone whos interested.

the PTS file that will be imported is very specific. it has to be a space deliminated file, with the following format

Pointcount

X Y Z Intensity R G B

Intensity is a float value 0-1

Example

2

0 0 0 .5 128 128 128

1 1 0 .5 128 128 128

Most programs can export an ascii file, XYZ, PTS, etc, as long as its in that format, you can just change the file extension to the pts extension for the converter.

Cylone and LaserControl wasn't exporting both the intensity and the RGB, so I edited the file in excel (used excel because of the tabular format, also it was a small test file, 20k points only) and added the column for the intensity manually. This allowed the converter to run properly.

Travisto,

We are testing Helix as well and have imported a file with 5 million + points.

It looks good, but is there a way to convert some of the point cloud points to max points?

We need that to be able to construct environments from it.

Thanks,

David

I have tried a few different things to get actual points in max. If you can export your points as a DXF, it will save them as AutoCAD points, then you can link them in Max. But this is VERY slow and will crash a lot. I have 12gb of ram, which isnt super high, but it crashed with less then a million points using the dxf.

There was a commercial for IBM where a company took the scanner points and did some manipulation to them, but I dont know what their process was. But they figured out a way. They may have made script that recreated max objects using the XYZ coordinates of the points? I dont think it would be very hard to do if you know MaxScript, since the point cloud formats are very simple.

I want to buy this product。

how much it？

And I need it 。

Lab products are not typically for sell. They are testings areas for features that might get implemented into the new version of products. Im sure we will see Pointcloud support in max over the next few version, similar to how ACAD and Revit works.
