Hello to everyone,
i have illustrated a quadratic bevier curve from point P1
to point P2 using a control point C.
What is the equation of the quadratic curve in order
to find some other points on it?
Thanks in advance

Hello Thanasis,
don't really know if this belongs here...
In general the equation of a (non-rational) bezier segment is
b(t) = \sum_{i=0}^n b_i \cdot B_i^n( t ),
b_i your n+1 control points,
B_i^n the Bernstein-Polynomials of degree n,
t
Hello Thanasis,
Here is the equation in the computer notation:
x(t) = (1-t)*(1-t)*p0.x + 2*t*(1-t)*p1.x + t*t*p2.x
y(t) = (1-t)*(1-t)*p0.y + 2*t*(1-t)*p1.y + t*t*p2.y
p0, p1, p2 - control points
Best Regards,
Alexey

A while back Phil helped me figure out why certain fonts were displaying oddly
(incorrect height calculation) in Java:

The root was that Adobe software had installed an PostScript Symbol font
(SY_.PFM) into the Windows Fonts
You can run the app with the flag -Dsun.java2d.debugfonts=true to see which
font files are accessed by 2D. But you may have a lot to wade through if the
problem
is that some font we expected to find is missing, as likely we will open all
files.
Still you may get a clue.
Another approach is that
I am having two problems:
1) on fedora core 4, Sun's JDK 1.5 was able to at
least imitate the full screen exclusive mode. Not
anymore on fedora 5. (both with gnome and xfce). I
tried both the current JDK 1.5 and the beta version
of upcoming JDK 1.6. COuld this be a new Xorg
problem?
Hmm,
Though new to Java, I am creating a program using 2d graphics. The only
problem I'm having is:
In the main class, I defined a JFrame.
Then I called my SetupCanvas class with:
f.add(new SetupCanvas(c), BorderLayout.CENTER);
In SetupCanvas (which extends Canvas), I draw stuff on the screen
