Fastest 2d polygon draw method?

Question

User399274 posted

Dear Xamarin forum users,

Please would you suggest the fastest way to draw an immense amount of 2d polygons. I've tried SKPath but it involves repeated method calls per point! Is there a faster skiasharp facility for batch drawing loads of polygons?

Many thanks in advance.

You can use Xamarin.Forms Shapes: Polygon control to draw 2d polygons directly(but you need to know all of Points) like following link.

https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/shapes/polygon

And you do not need to repeated method calls, just use this control your xaml code.

Intellisense shows Xamarin.Forms.Shapes.Polygon to be not yet added!?! The dependencies that I have are: Skiasharp.Svg (1.60.0) Skiasharp.Views.Forms (2.80.2) Xamarin.Essentials (1.6.1) Xamarin.Forms (5.0.0.1931)

I don't think that I'm missing anything!?!

Please add Forms.SetFlags("Shapes_Experimental"); in the onCreate() method of MainActivity.cs like following screenshot.
