I'm on day 7 of studying jit.gen and jit.gl.pix (which could still use some clearer examples with very simple things in the documentation :P )

Regardless, I'm a determined noob who found an excellent page with 28 tutorials on shadertoy. 

The tuts are great because they start out from the simplest elements (which I still miss with the jit.gen, jit.gl.pix examples) and so far its going good.

Translated tuts 1-12 into jit.gl.pix with codebox (When this is all done theres a Wiki page for jit.gen noobs coming up, no-ones going to go through the brain ache I had with ++ having to be += )

So yeah tut 13 got me stumped, for the jit.gen wizards probably a simple thing.

I've got one error with my codebox so if somebody could point out what my nooby mistakes are with a clear comment or two then I'd be eternally grateful.

Endless thanks for this Andro ! I got my eyes on this post :-)

hmmmm. can't post tuts 1-12, forum won't allow it, the page just won't load.

Strange I can post comments but not the copy compressed code.. :P

okay copy compressed still won't work so I've zipped it.

Bit of a messy patch but I'll tidy it up later.

Just use the gswitch to swap between presets, all original scripts are in comment boxes in the codebox objects.

Gen wizard for Tut 13 ..


this would make a great contribution to the wiki, if you feel like taking the time to put those up there.

i modified your code for tutorial 13 to get something working. i'm just using snorm to calculate the circle radius, which doesn't properly take into account the aspect ratio to get a proper circle.

hey andro, thanks for sharing these!

Which page would be the best to add the "copy compressed" to, and which section ?

i created a starter page for you on the opengl category:

The page with the tutorials seems to be down :P

The shadertoy site was down for a while, its back online now.

For the (tidy) patch with shadertoy to jit.gl.pix conversions

Hey, slightly off topic, I've been trying to get familiar with using the codebox, as forays into porting shaders!

Presently I'm trying to port a mandelbrot / julia set as shown by dan shiffman in his Processing/p5.js videos. I'm using jit.gl.pix and this code as my starting point :

https://github.com/CodingRainbow/Rainbow-Code/blob/master/challenges/CC_21_Mandelbrot/CC_21_Mandelbrot.pde

Now, I'm having an odd issue trying to port these two lines:

// Calculate amount we increment x,y for each pixel

I'm trying to store it in a vector called delta, and even though I dont get any errors during declaration, it doesn't show up in the code window, and I get an error when trying to use it! Any help appreciated, thanks!

  float dx = (xmax - xmin) / (width);

It's hard to tell without seeing all the code, but it's possible that it isn't showing because the variable wasn't being used -- we have an optimization pass that removes code that has no effect on the output.

Looks like a good resource, is there a more current link?

Jit.gl.pix codebox almost there must be something simple I'm missing..
