Passing a preprocessor directive to MSBUILD via the command line instead of #DEFINE in code

I recently wanted to pass a preprocessor directive (as in affecting /define in csc.exe) to MSBUILD on the commandline instead of using #DEFINE/#UNDEF in the source code or modifying the configuration properties in VS. (After all, isn't that the idea of Read More...

3D Math Primer

Living in Avalon 2D/3D means doing math -- more math than I've done in a long, long time. My trig is pretty rusty, not to mention my calculus. As a refresher, I've been reading a great book called 3D Math Primer and am loving it. Very simple, clear, incrementally Read More...

Bezier Time - A Tool For Visualizing Time as a Bezier Curve To Create Avalon KeySpline Animations

So, two posts ago, I showed how to do animations using splines, which allowed me to create the bouncing ball affect. The key to using splines in Avalon is setting the KeySpline attribute, which is how time is partitioned in the animation -- the rates Read More...

The Beauty of Bezier: Splines, KeyFrames and More Bouncing Balls

In my post yesterday, I looked at doing non-linear interpolations (aka the bouncing ball effect) for animations using animation composition. There is another way to achieve this effect using spline animations. By using spline animations, you can specify Read More...

Animation Composition as the Composing of Space and Time: Explicating an SDK Sample

I've been playing with the SDK sample I referenced earlier to get a better handle on animation composition and thought I'd share my particular angle of pursuit which may be helpful. First off, here is just a XAMLPad version of the sample I'm interested Read More...

Gnarly SDK Sample: Animation Composition

My favorite SDK sample is under \Graphics and Multimedia\Animation and Timing\Animation Composition sample. First off, it has a super elegant but very powerful transform that animates a panel to a very cool effect that mimics 3D in a 2D space. Secondly, Read More...

Rotation3D, RotateTransform3D, Rotation3DAnimation, Center, Angle, Axis

I've been spending some time with the Rotation transformation and animation classes in Avalon. These are very nifty and much easier to learn and use than Quaternions. Thanks to the 3D guys for adding this class. If you want to rotate something, you definitely Read More...
