A bunch of tweaks (GLSL)

[Patryk Kizny]

Hey all,

I've been playing with fragmentarium recently and added a few tweaks that I'd like to share with you.
I used 3dickulus 1.0.6 build and mostly built on Kn2 raytracer.

Here's what I've got and the frags will follow shortly:

• Added Box and Sphere folding to Quaternion classic fractal
• Added box culling (at the moment it merged with a DE formula, but maybe there's a more independent and elegant way of putting that together)
• Added fractal repositioning (scale, rotate, translate) and twisting (IQ way)
• Tweaked IQ Clouds that way, that now it supports 2 different levels of clouds with separate directions, speeds etc…

Tweaked the Kn2 raytracer so that we have:

• Sunlight (global, directional, no decay, has shadows)
• Spotlight (positional, with shadow, glow and volumetrics)
• Support for multiple spotlights would be a cool thing, but would require a bit different approach and would be good to have tweaks on the Cpp side to dynamically add light instances
• Better FOV for camera - now it supports either horizontal FOV input (in degrees) or film gate width and focal length of the lens
• Tweaked camera so that now it includes 3dickulous keyframes and also extra Eye" and Target" vectors adding to the base layer that allow for scripted camera transformations

The last thing is particularly usable for adding simple camera movements (linear).
Thanks to that camera and other parameters can react to the external data. I explored this workflow to allow for 2 things:
- creating and exporting camera in external 3rd party software and importing it for use in Frag for compositing
- creating and exporting sound keys and importing them in frag to animate morphs and changes of the scene reactively to the music. This require a bit more insight, but I'll shortly post a tutorial and examples on how to do it.

I'll be happy to share frags as soon as my workstation is done rendering yesterday's batch. Currently it's a bit unresponsive

Sounds great - and pleast post some samples of your works as well - I would love to how this looks!

Here are frags.

I included a few simple presets demonstrating some of the features, but that's just top of the iceberg.
As you add all this stuff it's becoming slightly slower, particularly with volumetrics.
Probably lighting part could be further optimized.

nice I'll be checking it out over this week,  it sounds good.
thanks for the contribution
