the generated blocks are very few and voxel is very tiny • SOLVED

[fffiloni]

hello @Zarbuz ,

i am on macOs 10.15.7, and used the lastest release of FileToVox with this command: ./FileToVox --i /Users/sylvainfiloni/Downloads/rainbow\ 2.ply --o testvox3

I wonder why the vox file generated is very small, with a very low value for blocks. Here is the console output with the "rainbow 2.ply" file

What did i do wrong ?

[fffiloni]

I get a voxel model but very tiny. Take a look at the "rainbow 2.ply" output on my machine:

I'm missing something, but i don't know what

[Zarbuz]

You must specify the grid-size : --gs 256 for example

[fffiloni]

Alright it works, but i still get an error with colors, i read that i may need to install libgdiplus ? i did, but seems it's not working :(

Yes this is a known issue for Mac, someone seems to made a fix here : https://github.com/Zarbuz/FileToVox/issues/46

Thanks Nicolas, i close this thread, as you solved the initial issue, and will open a new one if i can't handle the color related one ;)
