Linescreen (Composition by gtoledo3)
This is a glsl shader that takes texture input (vid, still image, etc.) and does some fun level dithering, and line screening. The controls are as follows: layers - controls amount of color steps. mode: 0-BW, horizontal linescreen. 1-BW, vertical linescreen. 2-BW, grid linescreen. 3-Color, horizontal linescreen. 4-Color, vertical linescreen. 5-Color, grid linescreen. line: density of linescreen. red/green/blue: color levels when in one of the color modes. vignette/vignette Radius: turn on vignette, and control radius. gamma/gammaLevel: turn on gamma, control gamma level (gamma from an example by psonice). |
Some useful configurable inputs on layer, line and mode.
really cool, i like it very much. here is my quick and dirty remix: http://pixelnoizz.tumblr.com/post/25774250142/gtremix
Cool looks :)
I can't get anything but black from this, I'm on Lion 10.7.4 can anybody confirm that OS version?
Looks interesting as does the cool @pixelnoizz re-mix
Worked ok for me, but there's a slight chance I have 10.7.3 loaded, I cannot remember.
Can you try plugging in a still picture instead of the video feed, or see if the shader program indicates any errors? Thanks! :-) Every so often I run into stuff with that new "FaceTime" camera (I think that's what they call the iSight replacement w/ higher res?)....maybe that's it?
