Prototyping a WPF-3D game design workflow using TrueSpace 3D, Expression Blend 3 with SketchFlow
Interesting article on SketchFlow by Don Burnett:
"Expression Studio’s Blend 3 With SketchFlow is an amazing tool. I have known about SketchFlow for a very long time (since March 2008. Microsoft had worked on gathering idea for it and spent a lot time on the concept, from customer feedback as early as 2006-2007 (maybe even before that). It has been in the works for a very long time with a huge amount of planning on the Expression team’s part.
While it is not UML, Sketchflow gives the same benefits and more. You can literally take a wireframe graphic to completed design all in the same tool. The player lets you share your work with your clients and fellow team members, let them mark up comments and make enhancements and changes and doesn’t require you to even be inside of blend. You could share it as a file (really a WPF based application) or even on the web on a shared website using Silverlight."
