FRAGMENTARIUM - My first video Test

[vinz]

Hi,

this is my first video test about, fragmentarium camera interpolation from 3dickulus.
As he requested an animation hahaha, i've done one. (fastly during last night)

But please don't be harsh with me, i know this is a draft result with a lot of mistakes and also very short ( 20 seconds )
i didn't really had time and ressources to do more.
I also hesitated to share it, but as it was ok on vimeo!..so let's get go ...

Here the link, for who have 20 seconds hahahaah  :

Don't FORGET TO ACTIVATE HD ... otherwize it's more than ugly !!

some details :

used:
- used 8 keyframes ( interpolation was done pretty smoothly )
- gi renderer with 500 subframes per frame ( approximatly 35 secs rendertime perframe )
- render size 1200 x 600
- used a virtualdub to x264  encode to add some credits and sounds.


Also now , inside fragmentarium , we have a good tool to create some animations.

HAhahahaha !:D 

[3dickulus]

hmmm looks a little bumpy  is that just internet playback? or is it the actual rendering?

[vinz]

what do you mean by bumpy? if you are talkin about the camera path, it's perfectly smooth ... don't worry about that
if there is some jump in the video it's probably because of the encoding ... or so ...

[3dickulus]

yeah I hope so, looks like a double frame bump, if it looks proper when you play it on your machine then great, if it is a double frame bump then I have to dig into spline routine that generates the points for each frame, they are precalculated and stored in an array so I should be able to dump the list of points and see if there are duplicates or just reeeeally close together.

[vinz]

yes you're right , i've difficulties to play it smoothly on my machine, i thought it was video compression ... anyway i've sent u a link to smaller video to check on your side.
but i suspect also, my multitasking to have some impact on this. need to do a real test in controled conditions.

[3dickulus]

again, hard to tell, not knowing where your keyframes are, the two animations I did were 900 frames and didn't appear to bump, maybe it's the resolution of the spline routine using float, single precision, my video card is a little old and doesn't support double precision so maybe using double inside the spline routine will give better accuracy even if it gets converted to float anyways 

[vinz]

I'm pretty sure it's not a big deal  
i've just sent to yu the lastest compiled  windows binary and the frag i used for the animation if it can be helpfull  

[3dickulus]

thanks for the frag and exe

I think I've found it, rendering two frames identical, single step through the frames and you should see two the same

I load the mandelbulb-anim.frag and render from those settings, I see frame 54 and 55 as the same 60 and 61 are the same 118 and 119 are the same  but it's not where the controlpoints would be  they are 1 62 125 188

 it's somewhere in between but I'm not sure until I dig into this a bit further or until someone with better coding skill points out the cause or my mistake 

solution for right now is to hunt down the duplicates and delete them before making the animation from the frames,
oh pardon me, this is not a solution! it's a mediocre fudge! not my favorite flavor of fudge!

hmmm this may take a while 

[vinz]

Hahaha ! it's never easy as we want , don't blame you i'm pretty sure yu have the skill to find the solution, at this time a mediocre fudge is ok for me, better than nothing  
Don't focus too much take some distance it can help hahahah !
anyway, if you need some help, i'm sure you'll find some ... sorry that i can't do more on my side

[3dickulus]

thanks, it'll come to me, I know 

you can do one thing...

load the mandelbulb-anim frag
open the animation window
in the "Frame" box type in 53
then type in 54

when I do this the number stays at 53 so maybe it's not my hack but has revealed an underlying bug in the interface

record the animation frames (max sub frames at 1 for speed) and check 52 53 54 55 or try to find the dups

let me know the result

[3dickulus]

  I think I was right, single precision error, changed things to be double everywhere I could find that had anything to do with calculating frame

I won't believe it's fixed until someone else gets the same results as mine... no more duplicate frames!

and key frames are aligned better in the controller view.

[vinz]

HAHAHAHAHAH Excellent 3dickulus 
Well done 

i'll give a try asap.

here the link to the binary with your lastest code.

thanks, I'll reference it in the thread.
