Hi,

Could be possible in some way?

speleo3 commented 5 years ago

It's currently not implemented. Pull requests welcome :-)

@giagitom What kind of format would you expected from this? Raw data or a greyscaled image?

giagitom commented 4 years ago

Hi @JarrettSJohnson , I am thinking about raw antialiased data

giagitom commented 4 years ago

Hi @JarrettSJohnson , a question.. Does depth already contains raw depth data at the end of the ray-tracing procedure? https://github.com/schrodinger/pymol-open-source/blob/4948dd0fd40962bd5d5fa9e26618cd7e2f654905/layer1/Ray.cpp#L5623

Hi @giagitom , your guess is as good as mine here since I'm not too familiar with the ray tracing code. Doing a quick inspection of the values before the buffer is deallocated, looks like these depth values are between -1 and 1.
