Re: [JAVA3D] Andy's int to float problem

[Josh Richmond]

Hi Andy,

If all you want to do is make r, xc, yc, and zc into floats, but keep v as an int 
(which you need to do for your array declaration), just cast the calculation of v to 
an int:

float r, xc, yc, zc, bvol;
int v;

bvol = ((xc+r)-(xc-r))*((yc+r)-(yc-r))*((zc+r)-(zc-r));
v = (int) (bvol*200);

Point3f[] coordinates;
coordinates = new Point3f[v];

Does anyone knows how to set all my int values to float.. Cos i try to change my int 
v; to float but they show me an error that say

 Incompatible type for new. Explicit cast needed to convert float to int.
 coordinates = new Point3f[v];

  spanx = (xc+r)-(xc-r);
