Title: Funball code
Post by: M Benesi on September 10, 2016, 08:03:56 AM
It's also a plane! If you set the RotXYangle=0, it's a plane. RotIter changes the starting iteration of the rotation (which is applied every iteration thereafter). Basically, it's a thin cylinder, copied around a bunch. I think eventually we could try a more complex shape to copy, but until then. Try changing the splitrads around in the presets. You might want to increase the range in the code (of the splitrads) so the sliders don't stop you. I set it low (-20 to 20) because I wanted a bit more control?? hmm... funball.frag: https://drive.google.com/open?id=0B0EcJQ49B_yOMTlBSk0yYVN1am8 I use a modified ray tracer, so you'll have to change the include statement to the name of a raytracer you have, if you don't have this one. #version 120

Lots of fun there! Had to resort to fast-raytracer though, as the one with textures wouldn't let the whole thing compile:
Could not create fragment shader: 0(465) : error C7565: assignment to varying 'orbitTrap'
Failed to compile script (63 ms).
But fun forms, even a 'ball within ball' (lower middle)

Failed to compile script (63 ms).
3Dickulus told me a solution to that problem, and it apparently didn't propagate to my local files either (I remember trying it... but I don't know why it isn't in my code???). I'm using the palette anyway. Maybe make a palette only raytracer, and one with less palette options. I've got to come up with an interesting coloring scheme anyway (by iteration of split, by location in split, etc.). Change C:/Users/MBenesi/Desktop/Fragmentarium-1.0.13-Qt_5_3_2_MinGW/original.jpg to ./ or something? uniform sampler2D tex1; file[C:/Users/MBenesi/Desktop/Fragmentarium-1.0.13-Qt_5_3_2_MinGW/original.jpg]

nice work MB , that is definitely a fun ball!
suggestions...
1) if the texture files are in the Examples/Include folder you can just use the filename without the full path, planning to add an option in preferences dialog for a user defined path for textures
2) when distributing a frag that uses textures set them up to use the ones that come with Fragmentarium or include the files in the frag zip, again, if the texture files are in the Examples/Include folder they will automagically show up in the sampler widget pulldown list ;)
3) sorry I don't recall the fix for error C7565: assignment to varying 'orbitTrap' but maybe 'varying' is the problem?
4) nah, that's all I got

With colors. Working on palette only (no textures) fast raytracer for some coloring.
Maybe try this frag (it writes to the orbitTrap variable- use the z and w for the most symmetric coloring) it with some version of knighty's ray tracers with palettes, for the cool effects?

Post by: Sabine on September 11, 2016, 10:40:40 PM
Matt, had a go at things, (no programmer, me, so monkey, keyboard, you probably get the idea :crazyeyes:, praise to the frag gods for the debug dump ;} ) and the culprit is this bit
else if (MapType==1) {
polymaptexture2(orbitTrap.xyz,angles);
orbittotal=textoff+angles*texturespeed;
//color = texture2D(tex,textoff+angles*texturespeed)*intensity;
Tore it out and I am now funballing in full technicolor ;)
Title: Re: Funball code
Post by: M Benesi on September 12, 2016, 01:12:29 AM
Awesome... I updated the raytracer (in the following link) and made a frag called funballcolors too...
Put the raytracer in the include directory if you want to use it. Color set up? doy... I didn't set them up in the presets. Although apparently the "anim" in funball with colors does the color thing?? hmm..
Textures are out of the raytracer. Compiles a million times faster!

Perfect, works like a charm and indeed: compiles twice as fast or even faster than my attempt too! Thank you, Matt! :)
Also for the funballcolors:)

Quick post. I added accordion code and now it makes magic carpets. I suppose this stuff is where Persian rugs came from. Funballwithaccordion in the following directory. Also, try the MengerWithSplits- it makes Menger planets...
Anyway, I also made some incomplete Mandelbulb3d multi split functions (called ~~integersplit/ ~~integersplit3d), but don't have time to fix them up before I don't have access to the intertubes. They are in the following directory as well:
https://drive.google.com/open?id=0B0EcJQ49B_yOeUMwTkZwN29KM2c
Code is even more half baked then usual. Timelines being what they are, I've got to get some sleep before my long journey.
