shapes

I need to generate random lobulated contours such as the following Any ideas or algorithms on how to do this ?? The software I am going to use is matlab, however I have no problem if you post solutions in other languages too... p.s I only need to plot a random contour that resembles the above... How about this? degree = 5; numPoints = 1000; blobWidth = 5; theta = 0:(2*pi)/(numPoints-1):2*pi; coeffs = rand(degree,1); rho = zeros(size(theta)); for i = 1:degree rho = rho + coeffs(i)*sin(i*theta); end phase = rand*2*pi; [x,y] = pol2cart(theta+phase, rho+blobWidth); plot(x,y) axis equal set(gca,

I'm trying to make a progress bar in the form of a rounded rectangle drawn on canvas, this jsfiddle has the shape: http://jsfiddle.net/xT3ax/ this.beginPath(); this.moveTo(x + cornerRadius.upperLeft, y); this.lineTo(x + width - cornerRadius.upperRight, y); this.quadraticCurveTo(x + width, y, x + width, y + cornerRadius.upperRight); this.lineTo(x + width, y + height - cornerRadius.lowerRight); this.quadraticCurveTo(x + width, y + height, x + width - cornerRadius.lowerRight, y + height); this.lineTo(x + cornerRadius.lowerLeft, y + height); this.quadraticCurveTo(x, y + height, x, y + height -

How to draw plus and minus signs in using data property in Path object. This is my triangle path object. I need to change it to plus symbol. <Path x:Name="trianglePath" Data="M 0 8 H 12 V 15 Z"/> Here, I've created a plus and minus sign which is 10 x 10 pixels using XAML path markup syntax: <Path Margin="10" Stroke="White" Data="M0,5 H10 M5,5 V10Z" StrokeThickness="2" Height="10" Width="10" /> <Path Margin="10" Stroke="White" Data="M0,5 H10" StrokeThickness="2" Height="10" Width="10" /> When experimenting with designing your path drawing, it's helpful to set the path element's height & width

As far as I know for now (which is little), all the Views in Android have square or rectangular shapes. This is fine almost all the time until you want - what I actually want - to create non-square shapes that could handle events. My goal is to have a circle divided in 3 sections of 120° each. Each section of the circle should behave like a button. The problem is that if we look at those 3rds of a circle and place them in a square box that strictly contains them, they are overlapping each other: not practical to know which the user meant to click... I tried with a custom view in which I drew

I have a set of shapes which need to be drawn on top of each other. I need to re-order them such that the smallest shape gets drawn last (i.e. it will be closest to the user). Is there any way to check whether a shape overlappes (encloses and/or intersects) another shape. I know there is a method in Rect structure called Contains which checks whether there is an object within it. Is there a similar method or a way to simulate it on Shapes in WPF? Thanks in advance for any help. Cheers, Nilu You could probably use the Geometry.FillContainsWithDetail method. Its name is ill-chosen IMHO, but the
