  • Ray casting 3d metaballs implementation with Depth peeling and Bezier Clipping

I have found interesting material which can bed use in mobile games due to good performance. Fast GPU based 3d metaballs implementation.

After review the document I have struggle with implementation. Any idea how to implement this with godot shaders suitable for mobile games?

Anyone can help on this topic?

This is not purely a shader effect, you would have to implement this as a feature on the engine level. For best results anyways. You can also check out the VisualServer and see if you can't figure out something by poking around a slightly lower level.

But honestly, if you even need to ask here then this is probably a bit too big of a task for you as of now.

It might be easier to implement with Godot 4.0, since it can take straight GLSL shaders instead of Godot's custom shading language. That said though, looking through the paper it seems like a complicated shader to write.

Let me know if it possible. According to this white paper shader should receive some parameters from the 3D scene to proper render position and collision of metaballs.

did you ever figure this out? I started working on an HLSL implementation of that paper for Unreal, so it's not technically relevant to this conversation, but I'd love to chat with you either way
