What Are You Working On? September 2015

[QUOTE=Flyguy13;48677079]Here's some stuff I made messing around GLSL shaders over the past few months. (Click the link below them to see the animated/interactive versions)

This stuff is sick. How did you do that non-Euclidean geometry stuff?

Wow, getting Cubemaps to work was a hell of a lot more tough then I thought it would be, but alas it is done.

As I said months ago, I take inspiration for how mechanics should work based off of a few engines such as the source engine (primarily), so I wanted cube map regions which I could easily put any object into and have it reflect based on that cube map, but also be able to pass between these zones smoothly.
However the source engine seems to use that system only for props, and lets the component specify what [I]surfaces[/I] of the world should reflect it, instead of just a zone in general. This part I'm really not able to implement now (if ever), so instead I reused the mechanic that my point lights use and made my cube maps [I]volumetric[/I] and bound by a sphere, stenciled onto the world. So the user can specify how it should attenuate, so it can blend out onto a surface.

With this, any surface can have as many cubemaps on it as the user wants, they will just blend into the scene.

With a click of a button in the editor, the cubemap can be re-built, so it could even in theory be tacked on to an update loop and update itself every so often.

However cubemaps aren't to be used as a main source of detail (and certainly not used as mirrors, such as in the video). They look best on surfaces with a proper specular map. I'm going to create a proper video showing this and upload it somewhere that will allow such a filesize.

Just be happy there's no pressing demand to implement Swahili since it (like tumblr) has 18 genders.

I will stick with Indo-European languages, thank you very much.

Though in all fairness, if Tumblr had its own official language, it would probably be genderless. Or maybe they'd decline pronouns based on how much privilege the associated noun had?

Basically it scales the scene along a certain axis when a ray enters the box and starts marching the scaled scene while rays that don't enter continue marching the unscaled scene.
You can sort of see this when you uncomment "#define HIDE_BOX" in the shader and recompile it.

Here we go, a "practical" usage of my cube maps.

[video=youtube;gV-sCM8nG7U]https://www.youtube.com/watch?v=gV-sCM8nG7U[/video]

The only issue is it blending with the default cubemap in the "window" there (technically everywhere but it can't really be seen anywhere else). Perhaps I'll somehow figure out a way to omit surfaces that are within the range of an existing manual cubemap from getting blended in with the default cubemap, however that is an issue I'll put on the backburner.

Hopefully I don't have to say the word "cubemap" any more, I've used that word so many times this weekend.

The geometry behind it seems squished too.
Does the scene stay scaled after the rays exit?

Yeah it stays scaled when they exit, I didn't get around to making it unscale the scene when the rays exit the box yet but it is possible.

Here's a basic diagram of how it currently works:

Oh I thought this was a real instruction set

[editline]14th September 2015[/editline]

I'm working on implementing built in functions to my interpreter. Idea is to either have an array of functions, (sin, cos, abs, etc.) with associated strings, then go through the array when the program is run and hash them to ANOTHER array/list. This way I can simply call

 functionHashTable[hash(STRING)]

and get a function pointer from that, then continue from there

[QUOTE=war_man333;48674682]TDD is only good if you know that your project is going to be big. For small projects it's really overkill.
also no idea how to apply TDD, or just testing in general, when working with Unity projects.[/QUOTE]

Unity has a good toolkit for that.

thinking about rewriting my [url=http://shodan.me/stuff/liqsim/]fluid sim[/url] in asm.js. I got the gist of how to write asm.js by hand but I still need to figure out how to draw to a canvas or something using it.

Crosspost from WDYNHW, but, does anyone know of any good resources on [I]Phong[/I] lighting?
I'm going to attempt switching over, however the only one which describes a basic implementation of it in OGl is in a different language :v:

Before VS After (I forgot to save the exact lighting colors that were in the first picture)
[t]http://i.imgur.com/GnTdWhZ.png[/t] [t]http://i.imgur.com/nkJI1PQ.png[/t]

After looking at several different tutorials, I realized that my shaders were already set up for phong lighting...
...however the only thing that was missing was the normal interpolation, or rather I had only calculated my normal's [I]per triangle[/I] when instead they should have been [I]per vertex.[/I]

Quiet playing with repetition test. Looking for that "human" touch on the repetitions that digital pianos usually lack.[/QUOTE]

I'd love to hear some Scott Joplin through this, any chance of Solace, perhaps?

[Karmah]

Turns out I had messed up a part of my new normal calculation. This time it works fine, and now I can show off cubemaps on a surface of a sphere (couldn't before really with those separate triangle normals)

It also looks pretty cool if I start scaling the object with negative or zero values

The console I made [URL="https://facepunch.com/showthread.php?t=1483860&p=48681262&viewfull=1#post48681262"]earlier[/URL] seems to adapt well to my other Love2D projects:

It could use a combo-damage meter like in fighting games
(or whatever it precisely is. A part of the bar is instantly coloured in and then disappears a bit later).

My theory is that when your computer scrapes enough SH and FT retarded bitchfights it starts emmiting beta waves that turns you into a shitposter.
