POWERVR Insider. Programme Overview PowerVR Insider consists of all the work and initiatives we have to support developers. Your applications make our graphics technology shine, so we are keenly trying to support you in all the ways you need to succeed. We work hard to make sure that developers who are new to graphically rich applications, or mobile development in general, are able to start creating stunning applications immediately using their existing skills.

Bezier Curves Bezier curves (pronounced “bez-yeah”, after their inventor, a French mathematician) are well suited to graphics applications on the Macintosh for a number of reasons.

Bezier curves have some interesting properties. The Gruesome Details The description of Bezier curves below is going to get a bit technical. The Bezier curve is a parametric function of four points; two endpoints and two “control” points. Where P1 and P4 are the endpoints, P2 and P3 are the control points, and the wn’s are weighting functions, which blend the four points to produce the curve. Figure 1. Implementing Bezier Curves We can optimize the process a bit. More Fun With Curves. Programme réalisé - 2. Programme réalisé - 9. Math. Game dev. Welcome.
