In unity you can do:
Camera.onPreCull += OnPreCullCamera;
void OnPreCullCamera(Camera3D cam){
//...
}
But in Godot I don't know what the equivalent is. How do you add a function to the sequence which takes place before culling the camera. Thanks.

I don't think there is an equivalent, nor understand why you need it (I would expect that you can work in _Process). The closest I can think of is the frame_pre_draw signal of RenderingServer.
Addendum: You can get the Viewport inside of which a Node is with GetViewport() and get the Camera3D of said Viewport like this GetViewport().GetCamera3D().

\$\begingroup\$ The reason I think I need it is this script: github.com/aras-p/UnityGaussianSplatting/blob/main/package/… on lines 38 and 182. I'm trying to convert it to Godot, but it's a process. I'm not entirely sure why the function on 182 needs to happen when it does, but maybe you can tell me if it does. \$\endgroup\$Ethan– Ethan2023-10-25 17:19:34 +00:00Commented Oct 25, 2023 at 17:19

1\$\begingroup\$ Does the behaviour differ from what you want in any significant way when you put this code in
_Processor in a response to theframe_pre_drawsignal instead? If so, be sure to document that in your question. If you can't determine that yet, then you have not yet identified a need for an equivalent toOnPreCullCamera, and you should proceed further with your experiments until you have concrete evidence one way or the other. \$\endgroup\$2023-10-25 18:39:55 +00:00Commented Oct 25, 2023 at 18:39
