DOF help

Hi,

 

I’m new to Papervision so excuse any ignorance of what are seemingly simple concepts to you all.

 

I’m trying to build a project with a similar depth of field effect to the Absolut clouds in the submitted visions section at http://www.absolut.com/iaaw

 

I’ve seen the impressive Mr d00b DOF demo, but this approach (of creating a sequence of preblurred materials) will not work in ttis instance as I understand it as each blurred object needs to contain interactive material.

 

So, I went down the route of applying blur based on distanceTo(camera) and have a function triggering on ENTER_FRAME which runs a for loop to update the blur on each item in the scene.

 

Problem is that this seems to only be taking a value from the last item accessed in the for loop and changing the materials for all items based upon this.

 

If I blur one item will this also blur any other item with the same material or is each instance treated as a separate entity? I have tried creating one material bper object but this slows things down to a crawl and the same problem as above still applies.

 

Any ideas? Anyone?

 

Cheers

If you use the Effects branch, you can create a set of layer each with a blur filter with different intensity.

Then you will switch the objects from one layer to another based on the item’s distance from the camera.

 

In this way you can also use the same non-animated material for every object. And, most important, layer doesn’t slow down things.

 

I’ve to build a DOF in the next days, and that’s the way I’m planning to do it :)

Thanks for that, you mention not animated materials, does this include materials with dynamic content?

Hi Daniel,

The I do it, is to just have a reference Z, usually 0, and apply a blur accordingly to the movie.

hope it helps,
Pedro.

Hey Pedro,

Do you have a code snippet of this?

Not really a snnipet as much as copy from my working code but it should give you a rough idea.

public function calcFocus(e:* = null):void
{
material.movie.alpha = getValueForInterval(0, 30, 1, .6, pivotDo3d.z)

if(!ApplicationFacade.getInstance().specialFX)
{
material.movie.filters = new Array()
return;
}
var blurQual:int = 2
var myBlurValue:Number = getValueForInterval(-10,30, 0, 30, pivotDo3d.z)
if(pivotDo3d.z > -10)
material.movie.filters = new Array(new BlurFilter(myBlurValue*.2,myBlurValue*.2,blurQual))
else
material.movie.filters = new Array()
}


public static function getValueForInterval(min1:Number,max1:Number,min2:Number,max2:Number,input:Number):Number
{
return min2+(input-min1)*(max2-min2)/(max1-min1);
}

How can I do with a movieassetmaterial for my planes?

var material_mc1:MovieAssetMaterial = new MovieAssetMaterial("mc_1", true, true, true);
material_mc1.smooth = true;
material_mc1.interactive = true;
//material_mc1.doubleSided = false;
plane1 = new Plane(material_mc1, 1300, 2000, 8, 8);
scene.addChild (plane1);

Aloha Danial,

Here's how i would do it to get the lowest cpu usage:

1. Make a particle and a bitmapparticlematerial

2. At start, generate a array (or vector / dict.) of the clouds with x blurlevels. So you end up with one normal bitmap, second is blurred with value 2 for example, then 4 etc. to the max levels you going to use.

3. Make a blur level switcher based on for example the screenZ value of the particles to the camera. Aldo you can make all type of switchers. This is switch the bitmapparticle material for each particle at each frame.

The only downside to this is the memory usage but it saves a lot of cpu usage.

Here a old demo using the above:
http://www.flashbookmarks.com/demos/dofdemo2/ move over it and click to next formation.

Good luck with it.
