Blur and threshold in the main loop to simulate fluids

[kbups]

Hello,

Do you know how to implement the example below with Love2D?

I know how the physics engine works but I do not know:
- How to do the blur and then the threshold?
- Which are the better functions to use (for performance)?


Thanks in advance for your reply.

I guess you'd have to print the scene to a FrameBuffer and then apply the filters. But I think you would have to implement those filters yourself, I think there aren't any integrated in Löve.

I think you are trying to do something that is achieveable with shaders (PixelEffects in LÖVE)
They are added in 0.8.0

You should practise with pixeleffects first and see some great examples in this thread

And because pixeleffect is similar (basically the same) to GLSL there is very handy site with online glsl coding
