Java games rock!

« Posted 2004-07-05 16:57:49 »

Hey all,

I'm still quite new to all this but I'm trying to draw the contents of a file and I have a 4x3 matrix of geometric format line coefficients. But I really don't understand what this means except that this is line data.

Can someone explain how I might use this to draw lines? The file format is a Neutral File Format and the packet type is 32 (meaning Line Data).

32      13       0       3       0       0       0       0       0 // header
0.000000000E+0  0.000000000E+0  0.000000000E+0  0.000000000E+0  1.999999955E-2 -1.999999955E-2 -3.999999911E-2 -3.999999911E-2  4.826000035E-1  4.826000035E-1  0.000000000E+0  0.000000000E+0      
17      18 // these to #'s are end point grid id's

Any help much appreciated.

Well, I don't know what a Neutral File Format file is, but I would hazard a guess that the floating point numbers are X, Y, Z coordinates.  So it looks to me like you have 4 coordinates that form the corners of a quadrilateral, or something like that.

I have no clue what the numbers are in the "header", or what the "end point grid id's" are.

How do you know 32 means Line Data?  Is there documentation about the Neutral File Format somewhere?
