The situation is this;
I’d like to be able to use some raw 3d coordinates from a text file and display them, joined sequentially in a wireframe model. Then be able to rotate, scale etc the resulting model.
The coordinates aren’t from a 3d drawing package but rather measured - therefore each point is literally assigned three numbers, in a tab delimited file.
With a large number of points (i.e. over 100) is there a way to load in the file and then generate the resulting model?
I’d be really gratefule if anyone has any comments/ideas/solutions to this! 🙂

This is an approach I would use, just some broad brushstrokes…
#1 I’d write a perl script to put those 3d coordinates into an XML file, so
I could use the XML features in actionscript to load 'em in.
#2 In action script, I’d load in the XML file, and parse it to a 2 dimensional
array. So you end up with something like
myModel = [[x1,y1,z1],
[x2,y2,z3],
etc… ]
I’d construct the XML so as to avoid having to do huge amounts of XML traversal. e.g., it’s easier to break up \ via String.split() than to indvidually parse \
#3 The rendering pass would walk thru the array, and convert each x,y,z
triplet to a 2D x,y pair, using a basic 3d transform out of Foley Van \*\*\*\*. As
part of that transform, you would want a scaling variable and rotation variables, for whichever axes you intend to provide rotation on.
#4 I’d pay attention to the mouse dragging, using a mouse listener and use
that information to modify the rotation/scaling variables.
A model of only 100 pts or so certainly sounds doable. Get a copy of Foley Van \*\*\*\*, get a copy of Moock, and get cracking!

Thanks for the pointers! I’ll post some more details once I’m done!
