Blur effect

  • #1, by ke4Tuesday, 09. December 2014, 16:24 6 years ago
    Hi,

    is there a theoretical possibility how to use a blur effect on screen but not over all screen, but only use it on the corners?
    Something a bit like blur effect in Misfits?

    Thanks

    Not unless you write your own GLSL shader code. The blur in the shader toolkit is currently only applicable to the entire scene.

    That would be an amazing addition, if you could like choose an exact area with screen coordinates or something like that. Fingers crossed. smile

    Do you have any experience with GLSL? Could you tell how about difficult would it be to learn GLSL?

    No but SimonS does. He told me that it is essentially C. To me most of the GL code he's written in the shader toolkit script looks like pure gibberish to me!

    Looks like migraine inducing, eye straining code to me! razz

    I would like the blur affect whole screen, but only the edges. I want this because i'm trying to do something like memories effect. I guess i could set the scene from blured images.

    why not just create a semi-transparent white effect & maybe overlay an old movie style effect or maybe desaturate the entire scene?

    First 2 are possible without using the shader. Controlling saturation with the shader however is pretty simple.

    shaderSaturation(0, 3000) -- desaturate in 3s
    shaderSaturation(1, 3000) -- reset saturation over 3s
    1
    2
    3

    ...it uses decimal values, so 0 = black & white & 1 = default, 0.5 would be half saturated etc. The shader toolkit script is needed for this to work.
