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.

VRML rotations : how to draw a cylinder between 2 spheres

Asked by romarin12 in 3D Game Programming, Math & Science, 3D Graphics Software

Dear All,

I am looking for math formulae (or Java code) that could help me draw a cylinder between 2 spheres.

I am using Java to create a WRL file. The world is composed of several spheres (known x,y,z locations). I would like to draw cylinders between spheres, but I am struggling with the VRML rotation function.

So I would need a function that returns:
translation Ax Ay Az
rotation Bx By Bz Th
given 2 locations (x1,y1,z1) (x2,y2,z2)

Thanks,

Olivier
