DEFract 0.5 - 3D fractal explorer. Now with GUI!

Darn Canvases

This looks really impressive though! I'm about to go do some research on this

As soon as this version works correctly, I will make a canvas-free one!

Ran it on my WinXP low-medium level machine. Too sad that it can only run at < 1 FPS but it looks very very beautiful

How is it rendered (raytracing, something else)?
Also can we know your beast's specs that you ran it on?

I just looked at your code and I'm very curious because you made something similar that I tried to do. it's going to be a great learning resource

Well, I don't have an awesome machine. It's a dell laptop from around 2008, with a NVidia 8600M GT. (I reach 20fps only inside a fractal)

For some details, yup, it's raytracing. I did what is described here : http://blog.hvidtfeldts.net/index.php/2 ... ls-part-i/ (wow, looking back at it, I realize I ended up with _exactly_ the same raytrace code!). This is a serie of really well written blog posts, very inspiring and clear. The most difficult was the geometry part (projection plan and theses things ). I understood the basis of how the fractals are described so I could play with existing code (randomly adding rotations for example!)

I started this because I tripped watching mandelbox exploration videos ( like this one : http://www.youtube.com/watch?v=Tj6rip3G62Y)

Hey, coffee, I'm really glad to hear that! For the FPS, sure, I'm adding it right now. Also, I just found a cool way to smooth colors at almost no cost

it seems like when you move it changes the resolution of the fractal...could you fix that?

[Patalo]

Well, this is the expected behavior. I added this so that when you don't move, it takes time to render a better quality view. But since it's now possible to change the resolution by scrolling, it's more annoying than useful.
I think I will remove it. At the moment, if you go in your LÖVE save folder, you can edit the fractals' lua description so that the values stored in the tables "rt", "hd" and "hq" are always the same. (rt is for real-time quality, hq for still rendering and hd for screenshots).
Higher maxIterations and lower threshold means better quality and lower FPS by the way.

I updated the first post with v0.4. It includes a fix for coffee's configuration (and hopefully others ) and a better color smoothing (that sort of broke the "spheres" demo, but whatever. It wasn't even a fractal.)

Is there any ATI user who ever succefully launched it ?

I'm with NVIDIA. Mendel.lua runs for me "outside at stady 15fps and increases a bit to 20+fps navigating inside. Some peaks at 30-40fps in that example. The spheres example still cool "broken". Mendel-animated at 10-13fps at start general view. Sierpinski usually +30fps when moving. Vanilla LOVE values.

It works beautifully for me now. Interactive too, impressive.
I like how it has the low-res version for when I'm navigating and gets populated with the high-res if i rest.

Awesome, runs really smoothly as well, hitting vsync (so 60 fps).

I'm on Arch Linux with AMD Fusion and it froze my entire system. Awesome screenshots though!

[coffee]

OMG! A Residents based icon? What a cryptic taste! You are indeed the Great Eye(ball) among us! I shall obey you master!

Alas, my graphic card doesn't support Canvas.
According to the screenshots, i looks awesome, indeed.
Nice work.

A friend of mine has an NVIDIA ge force 8500 gt, it ran and it was usable (altough the movement speed was low), but I didn't see the FPS
