How to use desktopCamera pos as input camera pos , and align the GS render with mesh model ?

[cyz2727327]

Hi,

This is great work!

I have a quick question though, my web application has a 3D interface where I can navigate my camera to view a mesh model.

Now I want to feed my camera pos (4*4 matrix or a 1Delement[16]) into this and view the GS rendering from the camera pos, assuming I can make the mesh model and the GS model sharing the same coordinate, I would effectively align the GS rendering with the mesh model.

I've been trying to do this on my own for a while but it seems the GS rendering has a weird way of taking camera matrix. What I did was directly replacing actualViewMatrix with my desptopCamera pos, but it seems to have some inversed axis.

Can you give me some insights on this matter? thanks
