I'm looking for an algorithm to find bounding box (max/min points) of a closed quadratic bezier curve in Cartesian axis:
input: C (a closed bezier curve)
output: A B C D points

Hi,
Is there a library of data structures and operations for quadratic bezier curves? I need to implement:
bezier to bitmap converting with arbitrary quality
optimizing bezier curves
common operations like subtraction, extraction, rendering etc.
languages: c,c++,.net,python
Algorithms without…

Hello,
I have have a quadratic bezier curve and I want to calculate the slope of the tangent in a given point. For example, let it be the middlepoint of the quadratic bezier curve, therefore t=0.5 (please see the link below for a picture of this). I've calculated the first derivation of the formula…

I need to draw a shape whose boundaries are parts of parabola (that is quadratic bezier curves) using iText. I have found only method for drawing cubic bezier curves in PdfContentByte class.
So how do I draw quadratic bezier curves using iText ?
One way would be to use method for cubic bezier curves…

Hello,
I have a quadratic bezier curve and I need the Y coordinate of a point on the bezier curve for a given X coordinate. I know that in pure maths this can be easily done, but I'm wondering is there's a simple / another way for this in C# / WPF? Is it possible to get the single points used by…

I need to implement a drag and drop functionality, where I can define and constraint the route of the draggable object.
Like in http://www.kirupa.com/forum/showthread.php?t=330302 , only that i have the paths designed and not calculated by a math function. So, in fact, as mouse moves I need to tell…
