|Direct3D Layered Windows Demo.
This demo builds on the previous layered windows demo. In the previous demo a TGA image with an embedded alpha mask was used for the shape of the layered window. In this demo Direct3D is used to draw a rotating teapot to an off-screen texture. This off-screen texture is then used as the shape of the per pixel alpha blended layered window.
This demo was built using the June 2010 update of the Microsoft DirectX SDK. The required end-user runtimes can be downloaded here.
1. This demo requires Windows 2000, XP, or higher to run. The minimum supported operating system for the layered windows API is Windows 2000.
2. This demo requires the Visual C++ 2010 Library Runtimes. Download instructions can be found here.
