CloudCompare forum

Hello

I am trying to load a ply file which size is 736,412kb. It contains a point cloud with texture and normals.

In the console i have the following messages

[13:47:02] [I/O] File 'C:\SOT\z1npunts.ply' loaded successfully
[13:47:03] [VBO] VBO(s) (re)initialized for cloud 'z1npunts - Cloud' (399.53 Mb = 100.00% of points could be loaded)

In the top view I see white stripe in my model with missing points.

I have monitored the memory usage of the computer and it did not reach any limit.

I am using windows 7 with a 32bit computer and v2.6.0 CC version.

I am not sure if it is a file or a software problem.

Did anybody have a similar experience?

Thank you

Let me guess: does your cloud have very big coordinates? (typically above 10^6 in at least one dimension).

Otherwise you could try to deactivate the VBO(s) (it's in the display settings: 'Try to load point clouds on the GPU memory...') but it would be a bit strange.

yes..UTM coordinates in X and Y..
Cloudcompare does the shift before the loading..
is it a problem of version of Cloudcompare?
I tried the VBO option and nothing changed

ok
the y coordinates has no decimals and that is why I have the stripes
so it is a file problem
I still dont get why only 400Mb out of 720 are loaded...
thank you!!

How do you see the 400 Mb? Is it the increase in memory? If yes it's because CC uses 32 bits floating points representation internally while PLY use 64 bits.

the 400Mb is what CC console says
[13:47:03] [VBO] VBO(s) (re)initialized for cloud 'z1npunts - Cloud' (399.53 Mb = 100.00% of points could be loaded)

the size of my file is of 720Mb

thanks

So indeed, it's only 3 * 4 = 12 bytes per points (instead of 3 * 8 = 24 in a PLY file). Colors should use the same size (1 byte per component). And normals (if there's any in the PLY file) are never transferred to the GPU.
