And if you scale it by 0.00001, the mesh becomes 0.00000001. (2). If the mesh location difference between two points is 0.0002, then it will become 0.000000002 after scaling. (3). Can the code handle this?

 February 12, 2001, 13:53 Re: Graphics Problems #3 Amadou Sowe Guest   Posts: n/a The code should be able to handle this since it has a double precision option. This means that the mantissa to my real number representation has been extended. I just calculated my PC machine unit, it is about 1e-16. The machine unit is the smallest possible increment in a stored mantissa. If a number is represented as X = M.10^i where M = .d1d2d3...dk, i is an integer normally called the characteristic or exponent, and d1 is not zero, then M is called the mantissa.

I remember quite long ago, somebody asked a similar question, you might want to check previous archives. I had this only once, what I did was save it after scaling and reread in. If you'd like, I could check it out on my wkstation...

I could check previous archives if I knew what to look for. Any ideas. Finally, I will be more than glad if you can check it out on your Dell 620 workstation. What graphics adapter do you have in your workstation 620?
