Dude, gutted for you that you didn’t make the cut this time round. I feel it’s certainly not the last the world will see of Nicolas though!

What’s the next plan on the agenda?

Very interesting stuff indeed. Nice work Nicolas!

@lawrie
not sure it was, precisely why I’m being so pushy to collect votes.
anyway, thank you ^^

@dave (thanks mate!)
as the coordinates are mapped on a 0-0xFF scale, precision is 1/#FF. the same applies to the UVS ; this can lead to real ugly results (trust me)

the good thing is that we can store each vertex over X pixels. with 1pixels per channel (x, y, z), precision is leveraged to 1/#FFFFFF and if need be, we could use 2, 3 or X pixels per channel. the same goes for the UVS :)

about the scale now ( dirty little secret ) as you pointed out, we need to store extra info and in my examples, I was only playing with somewhat cubic or spherical meshes. it’s only this morning, using real objects, that I noticed that scales were fucked as the ‘header’ of the texture would contain only infos about the bounding box and the pixel count.
it’s not much to implement though :)

0 & 0xFF for each coordinate its not accurate but i guess you can multiply/scale/divide by an another pixel data to get more accuracy

Nicolas, idea #2 is genius!
What’s the geometric precision like though?

Awesome post – if this is what you didn’t use, your pitch must have been amazing!

hello you,

j’ai vite trouvé un autre nom à ce que j’avais codé
je suis passé de FFD à 3DPointModifier
car c’était plus cohérent par rapport au résultat du script sur wonderfl

en effet si tu essayes de déplacer en même temps tout les coins du boxFFD, sur l’axe X par ex, tu verras que toutes les vertices ne se déplacent pas en gardant leur intégrité ( conforme au box ) alors que dans 3dsMax c’est le cas…

and nice idea for the geometry export on Image !
