Tip # 272 - resetting pan zoom

A lot of people don't even like Maya's pan/zoom tool in the first place, I often recommend to shut it off in the camera settings.

this also allows you to do have two panels up of the same camera, and see a green square around the area you are "zoomed" into, which can be helpful.

However, someone recently asked "How do I reset the pan/zoom "
which I realized i had no idea, so I looked it up.

its under the attribute Editor of the camera,
open the tab for Display Options ,
and then open the tab under that for 2D Pan/Zoom

if you set the Pan to 0 0 and the zoom to 1 it will go back to its default , or no pan and no zoom.

this is something that may come in handy as a script, so.....

here is a little mel snippet you can paste on your shelf..


string $panel = `getPanel -wf`;

string $camera = `modelEditor -q -cam $panel`;

setAttr ($camera + ".horizontalPan") 0;

setAttr ($camera + ".verticalPan") 0;

setAttr ($camera + ".zoom") 1;

better turning particles...

I havn't tried this yet,, but it looks interesting....

this code was suggested by Eric Cloutier on cgtalk to make better turning particles. ive added a simple adjustment dividing the turn by the goalPP. the results are pretty acceptable. i think i see flipping occassionaly but not too much

the suggested code is listed here

and repeated here for reference with my adjustement....466 is my maxCount of particles which im using to get a percentage value for goalPP

nParticleShape1.customAim = ; //or whatever

after dynamics:
float $maxTurn = 0.1;
vector $curAim = nParticleShape1.customAim;
vector $vel = nParticleShape1.velocity;
vector $newAim = ;
nParticleShape1.customAim = $newAim/nParticleShape1.goalPP;

V-motion REAL flow plugin

Looks interesting, but at the moment I don't know enough about RealFlow to know how "revolutionary" this actually is.....
