示例1: CalcTargetFromPosition
public static float CalcTargetFromPosition(ref Vector3D target, ref Vector3D position, ref Vector3D? front)
{
Vector3D f = new Vector3D(1, 0, 0);
if (front != null)
f = (Vector3D)front;
Vector3D tar = target - position;
tar.Z = 0;
if (tar.LengthSQ > 0)
tar.Normalize();
float dotAngle;
dotAngle = f.DotProduct(tar);
//Vector3D.Dot(ref front, ref tar, out dotAngle);
Vector3D cross;
cross = f.CrossProduct(tar);
//Vector3D.Cross(ref front, ref tar, out cross);
float angle = (float)Math.Acos(dotAngle);
if (cross.Z < 0)
angle = MathHelper.TwoPI - angle;
return angle;
}示例2: RecalculateD
public void RecalculateD(Vector3D mpoint)
{
D = -mpoint.DotProduct(Normal);
}示例3: RegisterLoginResponseHandler
private void RegisterLoginResponseHandler(bool loginSuccess, bool redirect, string message, string reason, LoginResponseData replyData)
{
Vector3D forward = new Vector3D(1, 0, 0);
Vector3D target = new Vector3D(replyData.LookAt.X, replyData.LookAt.Z, replyData.LookAt.Y);
