Hi all!
I have a question for the math inclined. I am experiencing a lot of what I
think are precision issues in my overlay system when my view is 3000+ units
from the origin. The transforms are these:
ViewTG
|
ConsoleTG
|
Geometry
The console transform is scaling at 0.0006202004979235267, which tranforms
into image plate screen coordinates taking into account field of view and
screen size. The geometry is all specified then using screen pixel
coordinates, so using (10,10) for the pixel location for example.
Turning the view causes the most wobble in the overlay, but translating also
does it.
What is the solution to this? I am using floats for the coordinates, would
changing them to doubles help at all in this case? What about putting a
transform between the view and the console transform which moves it to the
origin?
