This method simply uses trigonometry to calculate the width of a regular hexagon. Figure 2 shows the geometry. Because the green triangle is a 30-60-90 triangle, the ratio of the short and long sides is 1 / √3.
To draw a mesh the GPU has to rasterize all its triangles, converting it to pixel data. It does this by transforming the vertex coordinates from 3D space to 2D visualization space and then filling all pixels that are covered by the resulting triangle. These two steps are controlled by separa...
As shown in the code below, we call thedrawPolygonmethod inside thepaintComponentto create a triangle on theGraphicsobjectg. ThedrawPolygon(int x[], int y[], int numOfPoints)method draws an outline polygon as per the coordinates specified in thex[]andy[]arrays. ThenumOfPointsgives the num...
Theprinttextoption, when set totrue, allows the "text" to be printed out; e.g., when a triangle is drawn, the names of its vertices will also be printed. The default mode isfalse. • Thefilledoption applies toclosedcurves (i.e., triangles, squares, circles, and ellipses). When usi...

In this example, a closed green triangle is drawn: A filled path can be drawn with theFillPath, which also requires aPathFargument: C# PathF path =newPathF(); path.MoveTo(40,10); path.LineTo(70,80); path.LineTo(10,50); canvas.FillColor = Colors.SlateBlue; canvas.FillPath(path);...
This is the first of the correct approaches to drawing a hole in a path and uses the "winding count" polygon interior algorithm to label the inside of the triangle as "outside" the bounds of our path. Winding count is the default way that CoreGraphics determines if a pixel is inside or...

SVG, or Scalable Vector Graphics, is a drawing language that can be used in web browsers. SVG allows you to create shapes without the need for plug-ins like Adobe Illustrator.
