I would like to draw a shape that looks exactly like this, with the same gradient fill:
using only XAML.
The radius of the inner circle needs to be configurable.
The radius of the outer circle needs to be configurable.
The width of the gap at the top needs to be configurable.
The white color needs to be transparent.
What is the best way of achieving this?

I need to draw a border or rectangle like a bill payment on shop.
For make it's as real, I need to draw a shredding effect with the bottom is a saw-tooth line instead of a normal border.
Would you please to give me some advises?
Forget borders. Terminate the bottom side of the white area as a normal rectangle, but stack immediately at bottom an image (e.g. PNG) with the perforation strip.
That's the easiest way, unless you need something that adapts to the rectangle's width.
Is it possible to create animations for two controls like they are on two sides of rectangle. And rectangle is rotating around its axe (3d)?
Something like this:
Blue side - first control, and the green one - second.
I.e. I want both controls to be shown one by one eternally.
I have a three point circle points in XL/Report.With the help of saved circle point in Xl want to draw the same circle in WPF canvas.Is any body has any idea ,how we can draw the circle if we know the circle points.
There is no built in support for this that I know of. I'm afraid you will have to do the math yourself. This site will give you the equations you need.

Once you have the center, width, and height, you can use the WPF Ellipse to render it to your canvas.
I'm trying to build a 3D earth with Wpf Viewport3D. I have created the earth and it works pretty good. Then I want to add a halo effect around the earth like this attached image:
.
Some recommend to use diffuse material for the globe model. Then build a slight larger globe model with emissive material and little opacity. But the effect is not very good. It affects the color of diffusion material like this:
How can I implement the effect like the first screenshot?
I've done exactly this by creating a ring, inner radius the same radius as the planet and an outer radius to relect the atmospheric depth. Oriented to 'face me'. Using texture coordinates into a LinearGradientBrush to have the atmosphere fade from sky blue to transparent black.
Alternatively, there are some fairly good PNGs around of semi-transparent cloud layers you could use on the slightly larger sphere.
No matter how I tried, there are blank areas in the corner when I try to fill in my brush which is created in ResourceDictionary. I tired Stretch = Fill, Uniform, and UniformToFill. None of them worked.
I guess you used transform rotation in your code. If you want to fill in a rectangle area. You must use rectangle shape brush instead of diamond or any other brush in shape other than rectangle. PS: rotated rectangle brushes may fill in ellipse, but will leave some blank for other shapes like polygon.
