What is the algorithm to co开发者_运维问答nvert a quadratic bezier (with 3 points) to a cubic one (with 4 points)?From https://fontforge.org/docs/techref/bezier.html#converting-truetype-to-postscript:
I am writing a program in java using the jogl opengl bindings. I need to create a bezier curve that varies in thickness along the curve. So far I\'ve only managed a thin bezier curve of single points.
I have 2 questions about bezier开发者_运维技巧 curves, and using them to approximate portions of circles.
Given a few sample points on a bézier curve, is it possible to work out the set of possible curves these points may lie on?
I have a task - draw smooth curve input: set of points (they added in realtime) current solution: I use each 4 points to draw qubic Bezier curve (1 - strart, 2 and 3rd - control points, 4- end). End
I am trying to draw high order Bezier Curve using OpenGL evaluators: glMap1f(GL_MAP1_VERTEX_3, 0.0, 1.0, 3, 30, &points[0][0]);
How can I find the point B(t) along a cubic Bezier curve that is closest to an arbitrary point P in the开发者_运维百科 plane?I\'ve written some quick-and-dirty code that estimates this for Bézier cur
Given a cubic bezier curve P0,P1,P2,P3 with the following properties: • Both P1 and P2 are on the same side of the line formed by P0 and P3.
I need an algorithm to convert a closed bezier curve (perhaps self-crossing) to a binary bitmap: 0 for inside pixels and 1 for outside. I\'m writing a code that needs to implement some operations on b
I have looked at this example using php and GD to piecewise-render a spiral with small arcs. What I would like to do is render an approximation to a spiral that is as mathematically accurate as possib
