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…

I have to use this function to get a Surface of Revolution (homework).
newVertex = (oldVertex.y, someFunc1(oldVertex.x, oldVertex.y), someFunc2(oldVertex.x, oldVertex.y));
As far as I know (FIXME) Surface of Revolution means rotations of a (2D)curve around an axis in 3D.
But this vertex computing…

This is an age old problem of interactive elements inside interactive elements, but I want a ScatterViewItem to contain other surface interactive elements such as a SurfaceButton or SurfaceCheckBox. I've got all my elements in there and they react to taps etc. The problem is that I only get the…

Hello,
I am trying to convert Core Surface RGB frame buffer(Iphone) to ffmpeg Avfarme to encode into a movie file. But I am not getting the correct video output (video showing colors dazzling not the correct picture)
I guess there is something wrong with converting from core surface frame buffer…

Surface is magic. Everyone using it seems to think that way. And I have to be honest, after working for almost 2 years with the platform I still get that special feeling the moment I turn on the unit to do some more work. The whole user experience, the rich environment of the SDK, the touch, even…

I am trying to understand how pygame surfaces work. I am confused about Rect position of Surface object.
If I try blit surface on screen at some position then Surface is drawn at right position,
but Rect of the surface is still at position (0, 0)...
I tried write my own surface class with new rect…
