Some fun effects shaders for the GLSLShader module

[Magic]

I just added two new shaders to the original post: Ripple and NoiseBlur.

Ripple responds to both X and Y params.

NoiseBlur (didn't know what else to call it) responds to X.

Here's a video I made with both effects. Watch in fullscreen mode at 720p to see the NoiseBlur details especially. Of course, in Magic it looks much better! Damn YouTube!

EDIT: I just realized the NoiseBlur shader didn't work properly on some Macs. I think I fixed it.

Oh, that's reallt great ! thanks a lot.
Could you share the project of the video ? it could be interesting

[Magic]

Sure, here you go.

Make sure to put the NoiseBlur.txt and Ripple.txt files in the same folder as the project.

Also, the project requires version 1.53, which is not released yet , but the Beta will work.

Ok, I'm having fun with shaders at the moment, so I just added yet another new one to the original post: VideoHeight.txt.

It creates a 3D height map based on the input brightness. X and Y params control the rotation; set them both to .5 to make the image face the camera. Pretty cool!

[damstraversaz]

great ! thanks a lot

The video height shader is great when it is mixed with its source. I've tried it with two different sources which gives a mysteriously unsettling effect which can be subtle or blatant. The ripple is also great when its mixed back in with its source.

I've added a quick new shader to the original post: Posterize.

The X Param controls the posterization amount.

[Magic]

...and here's another one: Pixelate.

X Param controls the pixelation amount.

[Magic]

And here's yet another very simple one: Opacity.

X param controls the opacity level.

I should say that it's MUCH more computationally efficient to manage opacity with the Alpha parameters in the ColorRGB/ColorHSB modules, but it's a little more complicated since you have to do a bit of math. See this tutorial for details: http://magicmusicvisuals.com/forums/vie ... p?f=3&t=28

hey thanks a lot eric. opacity is really useful. theyre all quite useful actually. no idea if this is way too much to ask or really simple (or you if you even do take requests ^^), but can you do bloom? (as in this: https://udn.epicgames.com/Three/Bloom.html ). x could influence the intensity, and y the distance.

[Magic]

I'll see what I can do .

I'm also planning on improving and extending shader support for Magic 1.6, which will enable even more third-party effects to be used.

you're such a tease!..

[Magic]

Two more shaders added: ArrayX and ArrayY.

These create copies of the image along the X and Y axes, respectively. I separated them because it's more computationally efficient.

X Param controls the number of copies. Beware that values closer to 1 can make your frame rate drop significantly!

[Magic]

I just added a neat little shader called Glitch.txt which glitches the video using audio input. It also has a nice CRT TV effect.

For the glitching, make sure you enable the "Audio->iCh." parameter, and set the "iCh. Index" parameter to 1.

[Magic]

Another one just added: a nice effect called Drawing.txt which simulates the look of pencil on paper. Cool when used with videos or live cameras.

That drawing shader is great. And VideoHeight too - have a bunch of grey height maps from terrain models of Australia and New Zealand that will get some use now! Should be able to get the height synced to the beat; cool.
Can't work out how to get the Array X and Y working though - any suggestions? Have tried with .png, should it just be a shape/colour with mask?

Oops, sorry about that. You're a Mac user right? It looks like there was a tiny little bug that prevented those from working on certain Macs. Can you try them again?

Note: if you happen to be using Chrome, try Safari temporarily instead... Chrome doesn't seem to let me download the new versions.

Thanks Eric, works a treat -bug fixed!
