[Papervision3D] 3D Lines

[Andy Zupko]

Hey L - 

It's quite easy, all you need to do is go a random direction from the
current position.  Here is how you can do it with the line:

//get the last vertex in the line
var cv:Vertex3D = line.geometry.vertices[line.geometry.vertices.length-1];

//add a new vertex to the line with random direction
line.addVertex(new Vertex3D(cv.x+Math.random()*80-40,
cv.y+Math.random()*80-40, cv.z+Math.random()*80-40));

Just exec that every so often (I do every 10 ms in that sample) and your
line will grow!

Hope that helps.

-Andy

Hi Andy,

Can you post something about the simple Brownian motion algorithm ?
I only find complicated physics equation from wikipedia like.

thx
L
