Code uses Bresenham Algorithm to draw a circle, with a modification parameter to increase/decrease the step for calculation of point. Bresenham Algorithm is used to reduce the calculation needed for drawing a circle by making use of property of symmetry
To Draw a circle on the given image. required informations are 2 points which are going to be marked by mouse click.
1st point is midpoint of the circle.
2nd point is radius of the circle.
This function uses rectangle command to plot a circle. The center is to be given in a vector form and radius is a non-negative number.
A simple wxPython/OpenGL application to draw a sphere.
This program checks whether a point (x,y) lies inside,outside or on a circle defined by 3 other points.
Syntax: iscircle(X,Y,x,y), where X=[x1 x2 x3] and Y=[y1 y2 y3]. Thus, a circle can be made out of these 3 points-->(x1,y1),...
%Draw a square of area 1 on the ground, then inscribe a circle within it.
%Now, scatter some small objects (for example, grains of rice or sand) throughout the square.
%If the objects are scattered uniformly, then the proportion of...
This function detects a circle in any gray scale image by thesholding using Ostu's rule. The range of radius for detection of circle can be defined inside the function named Hughcir.m.
Draws a circle or ellipse on a RGB image.
can be used to insert circles into movies.
Includes a little animation demo that demonstrates the use.
FILLEDCIRCLE Filled circle drawing
filledCircle(CENTER,R,N,COLOR) draws a circle filled with COLOR that has CENTER as its center and R as its radius, by using N points on the periphery.
Get radial scan of a matrix using the following procedure:
 Get coordinates of a circle around an origin.
 Average values of points where the circle passes through.
 Change radius of the circle and repeat  until rprofile...
Script that plots streamlines around a circle and around the correspondig Joukowski airfoil. It's obviously calculated as a potential flow and show an approximation to the Kutta-Joukowski Lift.
Iterative, robust fit of the exact equation of a circle to xy data. Outliers are identified based on multiples of current standard deviation and "set aside". The interative solution proceeds until there are no remaining outliers. Returns...
Lets you create a circle with N points in the current figure. Use the mouse to indicate the center and adjust the radius. Press ENTER to confirm the shape and output its X and Y values. The N parameter is optional. Default 20.
N = 3 can be...
GCIRCLE(FIG) draws a circle by clicking the mouse at the center and at some distance away in the figure FIG.
H = GCIRCLE(FIG) Returns the handle to the line.
GCIRCLE with no input arguments draws in the current figure.
DRAW_CIRCLE plots a circle patch which can be modified later by pressing
Shift+Left mouse button on the circle.
Circle's location, radius, color and transparency can be modified interactively using mouse. See help section in the file for...
This routine draws a circle with center defined as a vector CENTER, radius as a scaler RADIS. NOP is the number of points on the circle.
TdzXYChart can draw a two dimensional chart using different formats for lines and points. It automatically scales the axes. It can also draw a bar chart. The number of data series containing the values is virtually unlimited. A special chart type...
If you want to draw a 3D cube on your form you can use this component.
VSSCaptionText is a component to draw a caption in the titlebar on the right hand side (just before the min, max and close buttons) of any window that has the focus, or the foreground window and a title bar.It supports the XP Shadow effect for...
Pi is a constant, an irrational number and its notation represent the sixteenth letter of the Greek alphabet, though its value is equal to the ratio of a circle’s circumference to its diameter.
However, a Muslim scientist Abu-Abdullah...
