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.

How to convert viewport window to window coordinates?

Asked by utsav1234 in OpenGL Graphics & Game Programming

Tags: opengl, coordinates, window, convert, viewport

Hi,

I need to use gluunproject to convert 2D screen coordinates to 3D world coordinates in openGL.

If I need to convert the points of the viewport window itself, how would I do that?

So, my viewport has (0,0) in the bottom left and (120, 50) in the top right.

The gluunproject function takes window coordinates (winX, winY, winZ).

for each of the two end coordiates of the viewport,

Is winX1 = 0, winY1= 0? Then what is winZ1?
also is winX2 = 120 and winY2 = 50? Again what is winZ2?

Please clarify my thinking here. Thanks!Start Free Trial
