示例1: detectParticleHalfplane
// Detects whether a particle and a half-plane are overlapping (including the
// radius of the particle) and are approaching.
// If the two objects overlap and are approaching, returns true and sets the
// vector n to be the shortest vector between the particle and the half-plane.
// Inputs:
// scene: The scene data structure.
// vidx: The index of the particle.
// pidx: The index of the halfplane. The vectors (px, py) and (nx, ny) can
// be retrieved by calling scene.getHalfplane(pidx).
// Outputs:
// n: The shortest vector between the particle and the half-plane.
// Returns true if the two objects overlap and are approaching.
