Shaders and Supershapes
« on: October 21, 2011 »
I've been playing around with Supershapes (http://paulbourke.net/geometry/supershape3d/) this week.

I know they've been done to death a bit, but I thought it would be interesting to play with them and maybe come up with something new.

The code is still a work in progress, but I've got the shapes generating nicely (albeit with it with some weird inverted normals at one pole) and a phong lighting shader running over the top. Going to try and get some god rays and other stuff to make it more interesting and maybe try and make a 4k intro using it.

Loving GLSL so far :)

Nice!
With some slick sync it can be enough for a whole demo (proof)...

Thanks guys.

Hellfire, that demo is really nice! They certainly got their money's worth with that effect :)

Nice work Raizor!

Is it done all in pixel shader or did you use polygons?

It seems that someone else already did it here and here ;), ofcourse doesn't mean you shouldn't do your own.

Thanks Jace and rbz.

Rbz, it's polygon based, just shaded using a pixel shader. This looks like another supershape 4k too. They're coming outta the goddamn walls! :)

I've seen some of your stuff on Pouet lately, nice work! They're really cool, especially the 1k stuff.

I'm trying to get my head around SSAO atm, so much new stuff to learn :P

This is very interesting stuff. I am fascinated by supershapes, such a powerful tool to know how to use.

Nice one! Supershapes are really fun to play with. You're right that they've been used to death in the scene by now (especially in 4k's) but they're still damn nice :D

Something went bang :(

Maybe something to do with shaders on my laptop.

More than likely it's my crappy shader code. I'll take another look at it and upload a fix if I can see anything wrong.

Don't be too sure, it's only a little netbook thing and looking at what's in it it's an 'Intel graphics media accelerator' whatever that is, dxdiag reports directx 9.0c

I remember seeing this thread, but not the morphing shape, must've been in a hurry.

Cool stuff, how many poly's are on display there? A visible wireframe might work well too!  :kewl:

About 20,000 triangles atm. I'm buffering the data to the GPU each frame, so it gets laggy if I do more than that. Probably time to spend a hour speeding this thing up a bit. I have some mesh distortion stuff I want to try so will do both at the same time. So many projects, so few finished projects ;)

Will give the wireframe a try :)
