I am trying to find the percentage of games played with man to marking for a basketball league. There are two types of marking: zone (Z) and man marking (MM). If there are 10 teams such that each play each other twice, there are a total of 90 games. Each team plays a home leg and an away leg, for a total of 18 games a season. If I want to find the percentage of games played with MM across the league, can I count the number of MM games over the home legs and divide by 90? or do I need to count the 18 games played with MM for Team A, then Team B, then Team C, etc, then divide by 180?

  • In a given game, can one team use MM and the other use Z?

  • Both teams can use MM, ZZ, or any combination.

  • Then what is an MM game? If it means at least one team used MM, then using the first method could give you 100% even though MM was only used 50% of the time. So use the latter method.

How to combine Bézier curves to a surface?

圖片
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite My aim is to smooth the terrain in a video game. Therefore I contrived an algorithm that makes use of Bézier curves of different orders. But this algorithm is defined in a two dimensional space for now. To shift it into the third dimension I need to somehow combine the Bézier curves. Given two curves in each two dimensions, how can I combine them to build a surface? I thought about something like a curve of a curve. Or maybe I could multiply them somehow. How can I combine them to cause the wanted behavior? Is there a common approach? In the image you can see the input, on the left, and the output, on the right, of the algorithm that works in a two dimensional space. For the real application there is a three dimensional input. The algorithm relays only on the adjacent tiles. Given these it will define the control points of the mentioned Bézier curve. Additionally it marks one side of the curve as inside t
