Cesium 3D tiles. Docker stops in joining step #72

Closed linkas closed 6 years ago

linkas commented 6 years ago

Hello, For last few days I was working with this amazing tool to convert lidar data to cesium 3D tiles. By doing that i have successfully converted demo data "red-rocks.laz" to the cesium format, but when i changed input to the my data i have faced one issue and i cant find out how to solve it. Problem is that when i start to run docker it goes to joining step and then just shut down the process without error messages. Bellow i have attached screenshots from my docker window and screenshot with my data information from lasinfo window. docker-toolbox-window lasinfo_01 lasinfo_02

Can you please help me to solve this issue?

Here is my files. silo_25833.laz is original file. silo_out2_25833.laz is re projected . After i had problem whit original file I have transformed coordinates system by using PDAL 1.6 library.

I am very new to these thinks. Thank you very much in advance for your help.

When I build this file with the cesium.json configuration, I get lots of errors like this: Exception in pool task: Unable to fetch data and convert as requested: Red:uint16_t(41891) -> unsigned char

This means that your file has 16-bit color values, which must be scaled down. You should use the cesium-truncated.json configuration, which performs this scaling for you. I'm not sure why these errors aren't printed for you, but the truncated configuration works for me for your silo_25833.laz file:

thank you very much. one more question. How can I use cesium-truncated.json ? I should download it as a file to use instead cesium.json ?

It's already there in the same location as the cesium.json file you used before. So you will use build /var/entwine/config/cesium-truncated.json in your invocation.

linkas commented 6 years ago

I have tried cesium-truncated.json but result was the same :( i have attached screenshot with code and result.

I also have tried manually by using Lastools to reduce color value from 16bit to 8bit (-scale_rgb_down : divides all RGB values by 256 (to go from 16 bit to 8 bit numbers) but it also did not help.

Maybe you have some another suggestion ho to fix it? :(

Thx in advance

Usually when a docker build with entwine exits with no visible errors it's because the VM ran out of memory. I'm not familiar with docker on Windows, but I assume there's somewhere in the UI where you can specify the allowable memory for docker - you might try increasing that a bit.

Hi, As you assumed problem was in VM memory. I have increased it and know its working perfectly.

Thank you so mach for your help.
