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!

Lofted polygon radius causing overlap in parallel transport.

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

Tags: Radius 3D Lofted Parallel Transport Frame Rendering Programming Maths

I am generating the main points on which my CatmullRom spline is based as follows:

waypoint_Current += new Vector3(Game1.Random.Next(-8, 8), Game1.Random.Next(-5, 25), -Game1.Random.Next(5, 15));

If I have a lofted polygon created from a parallel transport frame that follows the spline then the tube created overlaps itself as shown on the picture attached. This gets worse as I increase the radius of the tube/lofted polygon.

How do I combat this?

I had a thought that it might be necessary to generate random points that have a distance between them that is longer than the radius of the tube but then I wasn't sure how to ensure that the interpolated spline points would be far enough apart to prevent the overlap from happening.

Can anyone help?

Thank you.
