Shaders I want to write


#21

So I’m still stuck in my research
I customized my shaders as much as I wish but I still get this bloom effect that I wish to replace by a simple smooth line ^^
My nerves and my brain will really appreciate any help

Hey CtrlZ,

Two notes…

  1. ISF is based on GLSL, which is just one part of OpenGL; here are two links for pages that have listings of some of the common functions and variables that are built into GLSL:


  1. Here is a quick shader I made that just draws a basic line from one point to another point, https://www.interactiveshaderformat.com/sketches/3434

Ok, I think we’ll be making this one a standard FX in the future, but here is the soft flip with a variable angle,

(I took out the bits for doing the color adjustment to the flipped image, and added in options for switching the flip h & v instead… lots of fun possibilities in this one though)

Thank You David
Now I have stuff to read for at least one week ! ahah :slight_smile:

the two dot point line gave me a new Idea !!


#25

Btw this a solution I made which as some horizontal problem for some value ?!
And the color selection is for the background not the line …

Can we hi-jack your thread with ideas for possible shaders?

I think there’s room in the world for a shader that would auto-generate a small overlay above any video, featuring the distilled palette of whatever video was being shown.

You’re from New York (more or less… ) so this could be one option…


Other palette ‘generators’ :




I love the idea of being able to easily add such overlays, or scale / composite them…
And my lo-fi attempts to recreate just through using heavy pixelisation haven’t been that successful…

What kind of color distilling science / magic is needed?


#27

COLLAGE
Maybe a bit trickier in shader land than with paper and scissors -
but have a scroll through and check out some of this guy’s endless invention and creativity…
Maybe someone’ll get some shader inspiration from how he milks such limited parameters in new ways…


#28

This thread is totally meant for people to share ideas for shaders they’d like to see exist; also hoping it provides some inspiration for other people to write some of their own!

Someone asked about triangle based FX on the FB group, here is the first thing I put together on that front…

I’ve yet to create a general purpose shader for this, but my friend Fish2000 brought up this LiveLeak blurry fill background style, and I made a tutorial on how to set this up in VDMX using multiple layers…

Doing this as an FX is a bit tricky because within ISF, filters can’t change the size of an image… but I’ve got some thoughts on how to make something cool and useful from this idea.


#32

It needs a little more tweaking, but after that Triangle Wrap FX, I started working on a more general purpose shape wrapping filter, which lead to this version where you can morph between some basic shapes…


#34

Along the lines of the shape wrapping / repeating styles, I’ve started on this new feedback effect, https://www.interactiveshaderformat.com/sketches/3500
