Hence, CC will need a better, ad hoc filter for that format, in order to get the job done.

For now, you can painfully use the data to craft by hand the sensor item..... or can you?

is CC able to add a sensor and editing data into it by hand?

And even better, if you could send me a sample file, that would very useful to check that I've done things correctly.

Rows 7-10 store the global transformation matrix that applies to the points (and I would assume to the sensor as well). At least that's what I could see in samples files such as some files found on http://www.libe57.org/data.html or Paul Bourke's site.

So in your case, I would expect row 3 to equal the 3 first values of row 10, and rows 4 to 6 equal the 3 first values of rows 7 to 9 (or something totally different depending on how the cloud was registered). Otherwise, this means that the points have been registered, but there's no 'sensor' associated.

if so, rename extension to whatever ASCII format CC support and the wizard form will let you choose what gives what based on any number of columns

The mesh, under it I have a cloud, materials and texture coordinates.

It the past I have sampled the data giving me somehting that I can then rasterize, but these are coming out worse that I already have.

Is the a way to export a raster or just a high res image of the mesh?

Thanks

Pretty sure this is a bug. When importing a PTX file that has been registered (eg. exported from Leica Register360), the Sensor coordinates come through at 0,0,0. This is incorrect. The sensor coordinates should be translated by the values in row 10. See here: https://wiki.photoneo.com/index.php?tit ... ile_format

Furthermore, lines 7-10 define the transformation matrix for the sensor. See screenshot below, which shows the transformation matrix in a registered PTX next to the correct sensor location in CC (from an E57 file of the same cloud)

It's now common for PTX files to include normals. Leica Register360 now has this option for exported PTX files. They have 10 columns in total: X Y Z int R G B Nx Ny Nz. Any chance you can add support for this extended PTX format?

I sometimes use https://colorpickerimage.org/ on screenshots/exports just to verify whether the RGB values are really changing or if it’s mostly a display/rendering issue inside the viewer.
