The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

2D Image as a 3D Texture using Direct3D in C# .NET 2005

Tags: texture, directx, direct3d, 2d, image
I have a 16-bit grayscale image that I window and level to a 8-bit image.  Window and leveling involves two values, the window and the level.  Window is how big the range of pixel values within 0-65535 to display.  The level is where the midpoint of the window would lie.  Example: If window and level were 10,000 and 25,000 respectively, it would take the values between 20,000 and 30,000 and map it to 8-bit grayscale and display that image to the screen.

Now, whenever the window and level change, a mathematical formula can be performed to figure out what pixel value should be displayed.  Someone said I should try to use Direct3D by putting the image into a 3D texture and just perform the mathematical operation to each pixel using the hardware so that it would be done much faster.  However, I've never used DirectX let alone Direct3D to do anything like this.  Does anybody know of where I can find some examples or tips on how to go about accomplishing this goal?
