normalized coords?
Jul 2nd, 2008, 3:16am  
i'm just trying to figure out if there's a way to use normalized coordinates directly in processing without having to write a custom function for converting them...

?

thanks,

if you mean for UV's on shapes the you can use
Quote:
textureMode(NORMALIZED);

i think what i meant was signed-normalized-coords.
what i've done is just to create a custom function that converts them so i can do things like

move3d(-1,1,0);

thanks,

There's a really good vector library that has many built in functions, including normalization.  It's a must have if you're doing anything in 3D.  Get it here: http://code.google.com/p/toxiclibs/

If you're using that library:

Vec3D move_vector = new Vec3D( -1, 1, 0 );

move_vector.normalize();

println( move_vector.toString() );

// access with move_vector.x, move_vector.y, move_vector.z

//etc....
