Insight Light - A M3D Lightning Tutorial

By gannjondal
[NOTE: 
  If the PDF looks weird within your browser then please download it and read it with any pdf reader !
  Seams that pdf.js makes salad from the pictures.]


This tutorial has been created with props to Sabine62 , especially her great tutorial Q-n-D MB3D Reflections and Transparancy and the deviation VL... inna-box?! .

While doing some own test with internal lights in M3D Sabine pointed me to her own experiment about volumetric light inside a box.
This brought me to do even more quite systematic experiments about internal lightning.
Sabine and me agreed that I would write a little tutorial about internal (volumetric) lightning within transparent objects.

Thank you very much, Sabine for all your work regarding that transparency stuff!!


Please find more details within the pdf.

All pictures have been created with M3D v189(x2).

will upload some more examples, but now it's too late here (it's 0:45. I'm getting crazy :lol:).

Thus for now only a link to my variations to Sabine's VL light example:  gannjondal.deviantart.com/art/…

              *****
ADDITION:
If you want to see a few "advanced" examples please find following entries:
  • Simple, but clear light:  fav.me/d8wry5f
  • Kind of candle effext plus some special transparency on secondary objects:  fav.me/d8ws4dz
  • Fancy color game, and an example what happens if the surface is not as straight as for usual dIFS:  fav.me/d8ws5js
  • Glowing of some warm light:  fav.me/d8ws6mk
     
  • Last but not least I want to point to another great picture which does fit the topic of this tutorial. - It has been created way before this tutorial. Unfortunately I did not see it earlier :
    It's Logspiral shrine by :iconkronpano:

             *****

Finally here the params of the preview image.
This version is not part of the tutorial itself (too many additional steps ;-)), but it is a better example of the 'disturbed glowing' effect described at the end of the tutorial.

NOTE:  A better rendered version can be found here.

OK, now I will try something simple to understand more because my first try, murano pearl, was without any explaination.

I tried most of the parameters without knowledge. I like the result but I think I was really lucky !

Thank you.
A very intresting tutorial. Very hard (don't worry, it's me, I'm a little dumb sometimes) but very well written and clearly understandable.
I'm a little...obsessed with lights  and I'm gonna learn a lot from this!! :) (Smile) :) (Smile) 
gannjondal's avatar
Thousand thanks for your kind words!

You are right, playing with lights can be very intriguing, although it's not always easy to handle that in MB3D.

I hope we'll see more results of your obsession ;-)
GBLXVIII's avatar
I hope too. :) (Smile)

Very nice tutorial!! It is quite funny how obvious some things can sound when you read the tutorial which took you ages to figure out.
Thanks!!
gannjondal's avatar
Yeah, that's as always. Afterwards most -even weird- things look easy.

Thank you for your kind comment. - Although I assume that you could not learn too much ;-)

Addition: 
  Just added your picture into my list of examples. It really fits the goal of this tutorial. Hope that it's ok with you ;-)
  It's really a pity that I did not see it earlier. Seams that I'm checking the updates here in dA too seldom.

There are always things to learn - or understand why some things work as they do.
So many thanks for the tutorial - the work and time you put into those are greatly appreciated by the Mandelbulb community ;-)

And sure you can use my image in the examples :bow: always a pleasure :bow:

Thank You For the Tutorial, Wonderful Work...:)

Wish it would be true ;-) - Thank you, Russ!

Thank you & Merci for your nice comment :-)

:clap: :iconthumbsupplz: :faint: :wow: :iconwowplz: Very fine tutorial. I confess I skipped over Sabine's image in a rush get through the deviation stack... Thank you for explaining her find so well and taking it up a notch or two! I will certainly give this a try even though VL gives me a 1st class headache ;)

Thank you very much for your kind comment ! :TipOfTheHat:

Well, I usually tend to ignore hearts as well , but in this case the light was interesting enough to me :lol:
PaMonk's avatar
Fantastic and wonderful.:D

i will have to look at this one.:thanks also for sharing this.
gannjondal's avatar
Thank you, Barbara.

I just hope that it's not (once more ;-)) too long :lol:

Nice work. Great idea to use the volumetric light in this fashion.
gannjondal's avatar
Thank you, Dave!
Playing with the lights is very addicting. As I see you are currently in a similar mood - with very amazing outcomes, by the way.
Sabine62's avatar
:faint: (and this is only my reaction to your render, must read the tutorial tomorrow!)

Update: read the pdf after all, couldn't resist: Splendid, Gannjondal! :clap:
You've taken the whole thing to the next level(s)! Thank you also for answering my postprocess question :) Saves me a lot of testing ;) Now of course, I must test the whole thing in MC to see what it does there;)
BTW The cut is Such a good idea to show what happens inside! Glorious
Will reread a few times and follow all steps.

Update: Did a quick run in MC (400x300), behaviour is as expected, stays nicely in the box ;)

Thank you so much for your kind words, Sabine! :-)

But it was me who could not resist. Playing with those lights is very addicting.

Although - while answering a comment from batjorge I had checked how he has built two of his more experimental pictures (Nightwish, and LED Play) and got the feeling that I have played that 'Kanonen-auf-Spatzen' game (my dictionary says 'sledgehammer to crack', don't know).

Anyway, I hope that the tutorial can help anyone.

Just had a look at Jorge's works, but neither has VL or other light inside, and there's no transparency there. He can do the most amazing stuff just with a map... or with dynamic fog on iteration... :) AND with transparencies and all. Not for nothing he is one of my MB3D-heroes! :)
English translation: It's probably sledgehammer to crack nuts? But not in this instance anyway! :)

Immer gerne, Gannjondal!

Bear up! At least we have found Jorge's trick quite fast :lol:
