[Qt3D] Setting a uniform per entity && drawing a single frame.
FredFred last edited by
I am currently working on a Qt3D project in which I would like to implement color picking. The usual way of doing this is to send a different ID for each drawn object to the shaders via a uniform. That means changing the value of a uniform in between draw calls.
- Is there a way of doing this without creating as many materials as there are objects ?
- Is there a way of asking Qt3D to render a single frame on demand ?
If someone has already written a clean implementation of this, I would appreciate the help.
