Another slider serves for setting the camera distance, thus making the binary clock appear closer or further from the screen.Įvery time the slider for rotation speed is moved, the rotation animation needs to be restarted to apply the new animation duration. The speed of this rotation can be adjusted through the settings window with the help of a simple slider. The binary clock has a rotating animation around the vertical axis. This way we project 2D Rectangles to a 3D surface in space: The 3D effect of the clock is achieved by adding the Digit class instances into a ViewPort3D object. This could be achieved by reusing the Binar圜lockPage class, which provides the core functionality for the binary clock (see the previous section). This project goes even further: it supports not only a simple preview mode, but inside the settings window it offers also a live preview to interactively show how each change will affect the output.Ĭlick to see the video demonstrating the Live Preview.

A screensaver primarily needs to display a full screen window, but it should also support a preview mode and provide some optional settings widow for customization.

What a Windows screensaver needs to be is basically an *.exe module accepting some well-defined command line arguments. Screensaver in 3D and Configuration with Live Preview

instances of the Digit class – are declared in XAML and their update is done in the setTimeToDigits() function. When all of this is set up, it’s enough to have a timer which updates our BCD digit values each second. The DigitModuloConverter class will tell us if the specified modulo of any integer value is greater than the supplied parameter or not. This logic can be generalized by using a WPF value converter, having some simple modulo computations inside. Similarly, the bit above the least significant bit needs to be lit if the BCD digit’s value modulo 4 gives a result of 2 or greater number, etc. For example, the least significant bit needs to be lit if the BCD digit’s value modulo 2 gives nonzero (that is, every other second of time). It’s the style applied to any specific bit which tells whether that bit needs to be lit or unlit at a certain moment of time. They're stacked one above the other, the least significant bit being placed at the bottom and the most significant bit at the top. This is what the basic structure of that template looks like:Įach BCD digit consists of four binary digits/bits. This way we could simply put six instances of the Digit class into some items container of our window and leave the rest of the look-and-feel-work to be done by our DataTemplate. The idea behind displaying a data class is to apply a DataTemplate to it. Secondly, the digits themselves don't even need to know anything about their visual representation, thus to represent a BCD digit, it’s fully enough to have a purely data class for them. The Core - Binary Clockįirst, the binary clock has a simple task: to show its six digits, one by one.
If you like the concept, but don't have it on your desk yet, then you can have it at least as your screensaver by downloading the attached binaries. Actually, we can better call it a pseudo-binary clock, since it shows the digits in BCD (binary coded decimal) notion. Maybe you already know the concept of a Binary Clock: it's a clock where you read the 6 digits of current time as 6 columns, each consisting of some lit and unlit LEDs. What you see here is therefore part of my WPF learning process, which I thought might be useful also for other enthusiasts of the technology. This binary clock project originated as a mere experiment to help me understand the above WPF concepts.

Screensaver in 3D and Configuration with Live PreviewĪlthough you may find several binary clock projects throughout the web, this article will show you not only how to create a binary clock, but also how to host it in space and use it as a 3D rotating screensaver – all of this utilizing Windows Presentation Foundation and its powerful concepts such as data binding, data templates, styling, automatic layout, animation and 3D support.
