[sharing is sharing] slitscan

ahhh, beautiful. and so simple yet so mind boggling...

Hey, actually, I screwed that patch up.

The dimensions in the first texture should be 1 x 480, not 720 x 480.

Also, try playing with the values in rota, changing them from 1 or 0 to 0.5. Pretty nice effects that way.

or use the uyvy2rgba shader for cross platform-y uyvy texture upload speedy goodyness - y -y stuff...

very strange, nothing appears for me ?

faster maybe?

and the shader

Yes, but I can't get it to behave like an actual slitscan for me.

Hey Barry,

The patch I posted recreates the exact effect you posted on my windows machine upon loading. Perhaps I'm missing something or your patch isn't working properly on my machine. My impression was a slitscan samples a scanline of a picture shifts it to the left and then samples the same scanline and keeps shifting. Can you clarify this for me? I really liked your patch and it gave me a bunch of cool ideas for shaders.

when i run this on my machine the resulting looks as follows... does anyone else get similar results?

I've been having fun with the tex_plane_t/s and figured out a super simple way of doing slitscan. It may not be the most versatile implementation, since it relies on jit.gl.render to have an erase_color 0 0 0 0 and fsaa 0 on your jit.window. But it's damn simple, that's for sure!!

Hi all, the patch above uses the shader td.still_slide.jxs

Does someone still have it, or where can I find it?

Thanks! Frank
