示例1: computePanAmount
import gov.nasa.worldwind.geom.Position; //导入方法依赖的package包/类
protected Angle computePanAmount(Globe globe, OrbitView view, ScreenAnnotation control, double panStep)
{
// Compute last pick point distance relative to pan control center
double size = control.getAttributes().getSize().width * control.getAttributes().getScale();
Vec4 center = new Vec4(control.getScreenPoint().x, control.getScreenPoint().y + size / 2, 0);
double px = lastPickPoint.x - center.x;
double py = view.getViewport().getHeight() - lastPickPoint.y - center.y;
double pickDistance = Math.sqrt(px * px + py * py);
double pickDistanceFactor = Math.min(pickDistance / 10, 5);
// Compute globe angular distance depending on eye altitude
Position eyePos = view.getEyePosition();
double radius = globe.getRadiusAt(eyePos);
double minValue = 0.5 * (180.0 / (Math.PI * radius)); // Minimum change ~0.5 meters
double maxValue = 1.0; // Maximum change ~1 degree
// Compute an interpolated value between minValue and maxValue, using (eye altitude)/(globe radius) as
// the interpolant. Interpolation is performed on an exponential curve, to keep the value from
// increasing too quickly as eye altitude increases.
double a = eyePos.getElevation() / radius;
a = (a < 0 ? 0 : (a > 1 ? 1 : a));
double expBase = 2.0; // Exponential curve parameter.
double value = minValue + (maxValue - minValue) * ((Math.pow(expBase, a) - 1.0) / (expBase - 1.0));
return Angle.fromDegrees(value * pickDistanceFactor * panStep);
