LÖVE

Works for me now, on nvidia.

Although, if i move the gaussian blur shader's slider all the way to the left, it errors with "line 4: undefined variable "nanf"
Probably a div by 0 issue

Nice work!
On the Gaussian blur effect if you move the slider all the way to the left you get the error:

Error

Cannot compile pixel shader code:
Line 2: WARNING: Only GLSL version > 110 allows prefix "F" or "f" for float
Line 3: ERROR: 'nanf' : undeclared identifier
Line 3: WARNING: Only GLSL version > 110 allows prefix "F" or "f" for float

I feel like somebody's already let you know about this error, but oh well.

I'd really like a bloom shader, I've never gotten it to work myself.

Incidentally, I just added a simple bloom effect. I am sure that could be done better (slime...?), but it seems to work.
The updated demo contains a second image where the effect is more visible.

Positive07 also did some efforts to get the shaders to run on android.
After fixing some stuff I got the to run on my phone as well.
There is now also an option to change the grain size in the filmgrain effect.

Any other suggestions/ideas for effects?
I'll try to complete the wiki with information how to write your own effects and how to get them into the repo tomorrow evening.

Hi there,

Congrats on the idea, this looks like a very good initiative.

The demo fails for me in several occasions (I just re-downloaded it again to make sure).

• When selecting colorgradesimple, I get "quickie/slider.lua:35: Invalid argument. (from main.lua:156)
• Gaussianblur throws an error if the slider is set to 0: Line 4: ERROR: Use of undeclared identifier 'nan' (from shine/gaussianblur.lua:91: in function 'set')
• A similar error happens when sigma is set to 0 in simpleglow: Line 4: ERROR: Use of undeclared identifier 'nan' (from shine/simpleglow.lua:104: in function 'set')

Too many.

• Scanlines
• Curved screen
• underwater
• water/rain in the camera
• night vision
• motion blur

Whoops... should be fixed now.

uhm..

I'd love to see a dilate and an erode shader

Really like the effects in this video:

A new error! Again when setting gaussian blur's variable to 0.
shine/gaussianblur.lua:75: Variable 'direction' does not exist.
A common error is to define but not use the variable.

Also same error with glowsimple, on glowsimple.lua:87

Awesome work, vrid! Very cool.

This is AMAZING.
Do you know if it works with cameras and scissors? I seem to be having troubles with it, and I'm not sure if its because of my misuse of it or incompatibility with those.
