Working with perspective 3D in Expression Blend 3

Posted by Corey on March 19, 2009 at 1:50 am.

In my last post about perspective 3d I showed a quick sample application on how to take an image, bind it to a slider and control the RotationY on the PlaneProjection object.  It’s easy enough to hand code one image, but now I want to design an interface.  So, I downloaded the newest version of Expression Blend 3.  First, the new interface is awesome, and I’m stoked about the direction Blend is going.  Anyway, after poking around, here’s how to access the Projection properties in Blend:

1

Locate the Transforms panel in the Properties Panel and select the Show advanced properties button at the bottom.

2

This opens up the Projection section.  Here you can manually adjust the values and the object on the Artboard will update.

Or, if you want to fine tune the projection click and drag the circle icon on the left.  You’ll notice the icon turns blue when selected.  I found this feature a little difficult to use; however it could be that this isn’t suppose to be used on a laptop touch pad.

This is the resulting object on the Artboard with the corresponding Projection properties.

  • I would change the title of this to an intro with perspectives or a Quick Tip on a new feature in Silverlight, because the article is very very light on content.  This is something thta someone can pick up in 25 seconds.

    I’ve downloaded Blend 3 on Friday. I created a basic rectangle with a black fill. I opened the Transform panel, opened up the “Show advanced properties” and I don’t see the “Projection section” you write about. Did you pull in a 3D object first?

  • A change from Blend 3 Beta 1 to Blend 3 RC is the Projection panel is no longer in the drop down menu of the Transform. Instead Projections are directly below the Transform.

  • I have the same problem as CFAP above. I’m still only seeing the X and Y transforms. Where is this theoretical Z axis? Thanks! (great blog, BTW)
