Skyline软件二次开发初级——6如何在WEB页面中的三维地图上进行坐标和方向计算

1.距离和角度：

<html>
    <head>
        <title>Coordinates 1</title>
        <object id="SGWorld" classid="CLSID:3a4f91b1-65a8-11d5-85c1-0001023952c1" style="visibility:hidden;height:0 "></object>
        <script type="text/javascript">

        var popup = null;

        function Init()
        {

            // defining two coordinates
            var coord1 = SGWorld.Creator.CreatePosition(-71.07542, 42.34930, 232.0); // The Hancock building
            var coord2 = SGWorld.Creator.CreatePosition(-71.05507, 42.35561, 105.0); // Target building

            // Placing some annotation on the terrain
            SGWorld.Creator.CreateTextLabel(coord1, "Hancock Building",SGWorld.Creator.CreateLabelStyle());
            SGWorld.Creator.CreateTextLabel(coord2, "Building 2",SGWorld.Creator.CreateLabelStyle());
            SGWorld.Creator.CreatePolyline(SGWorld.Creator.GeometryCreator.CreateLineStringGeometry([coord1, coord2]), SGWorld.Creator.CreateColor(255, 255, 0), 0, 0, "line");

            // Set a good view point for the scene
            SGWorld.Navigate.SetPosition(SGWorld.Creator.CreatePosition(-71.07802, 42.33974, 550.0,0, 34, -13));

            // Calculating the distance and angles from the Hancock building to building #2
            var distance = coord1.DistanceTo(coord2);

            var angles = coord1.AimTo(coord2);

            // Display a message to the user
            popup = SGWorld.Creator.CreatePopupMessage("Coordinate sample","",0,0,450,120);
            popup.InnerText = "The aerial distance between the roofs of the\r\nHancock building and building #2 is " + Math.floor(distance) + " Meters\r\n\r\n" +
                              "The aiming angles from the Hancock building to building #2 are:\r\nyaw: " + angles.Yaw.toFixed(5) + "  pitch: " + angles.Pitch.toFixed(5);
            popup.Align = "TopLeft";
            SGWorld.Window.ShowPopup(popup);
        }

        function Uninit()
        {
            if(SGWorld.Project.Name == "")
                return;
            if(popup)
                SGWorld.Window.RemovePopup(popup);
        }

        </script>
    </head>
    <body onload="Init();" onunload="Uninit()">
    </body>
</html>

2.位置和方向：

<html>
    <head>
        <title>Coordinates 1</title>
        <object id="SGWorld" classid="CLSID:3a4f91b1-65a8-11d5-85c1-0001023952c1" style="visibility:hidden;height:0 "></object>
        <script type="text/javascript">

        var popup = null;

        function Init()
        {
            // defining two coordinates
            var coord1 = SGWorld.Creator.CreatePosition(-71.07542, 42.34930, 232.0);
            var coord2 = SGWorld.Creator.CreatePosition(-71.05507, 42.35561, 105.0);

            // Placing some annotation on the terrain
            SGWorld.Creator.CreateTextLabel(coord1, "Hancock Building",SGWorld.Creator.CreateLabelStyle());
            SGWorld.Creator.CreateTextLabel(coord2, "Building 2",SGWorld.Creator.CreateLabelStyle());

            var pos = coord1.AimTo(coord2);

            SGWorld.Navigate.SetPosition(pos);

            // Display a message to the user
            popup = SGWorld.Creator.CreatePopupMessage("Coordinate sample");
            popup.innerText = "This sample shows how to place the camera at a specific position\r\nwhile aiming it to a desired point of interest";
            popup.align = "TopLeft";
            SGWorld.Window.ShowPopup(popup);
        }

        function Uninit()
        {
            if(SGWorld.Project.Name == "")
                return;
            if(popup)
                SGWorld.Window.RemovePopup(popup);
        }

        </script>
    </head>
    <body onload="Init();" onunload="Uninit()">
    </body>
</html>

3.移动指向位置：

<html>
    <head>
        <title>Coordinates 1</title>
        <object id="SGWorld" classid="CLSID:3a4f91b1-65a8-11d5-85c1-0001023952c1" style="visibility:hidden;height:0 "></object>
        <script type="text/javascript">

        var popup = null;

        var coord1, coord2, pos, distance;
        var time;
        function Init()
        {

            SGWorld.AttachEvent("OnFrame", onFrame);
            time = new Date().getTime();
            // defining two coordinates
            coord1 = SGWorld.Creator.CreatePosition(-71.07542, 42.34930, 232.0);
            coord2 = SGWorld.Creator.CreatePosition(-71.05507, 42.35561, 105.0);

            // Placing some annotation on the terrain
            SGWorld.Creator.CreateTextLabel(coord1, "Hancock Building",SGWorld.Creator.CreateLabelStyle());
            SGWorld.Creator.CreateTextLabel(coord2, "Building 2",SGWorld.Creator.CreateLabelStyle());

            distance = coord1.DistanceTo(coord2);
            pos = coord1.AimTo(coord2);

            // Set the start position at the top of the Hancock building
            SGWorld.Navigate.SetPosition(pos);

            // Display a message to the user
            popup = SGWorld.Creator.CreatePopupMessage("Coordinate sample");
            popup.InnerText = "This sample shows how to move a coordinate toward another coordinate";
            popup.Align = "TopLeft";
            SGWorld.Window.ShowPopup(popup);
        }



        function onFrame()
        {
            var elapsedTime = (new Date().getTime() - time) / 1000 // elapsed time in seconds
            time = new Date().getTime();
            pos = pos.MoveToward(coord2, 200*elapsedTime);   // 200 meters/sec

            var newDist = pos.DistanceTo(coord2);

            if (newDist > distance)
            {
                // Stop condition. if we are here, then we have passed building 2
                SGWorld.DetachEvent("OnFrame", onFrame);
                return;
            }

            SGWorld.Navigate.SetPosition(pos);
            distance = newDist;
        }




        function Uninit()
        {
            if(SGWorld.Project.Name == "")
                return;
            if(popup)
                SGWorld.Window.RemovePopup(popup);

        }

        </script>
    </head>
    <body onload="Init();" onunload="Uninit()">
    </body>
</html>

4.朝着某个对象移动：

<html>
    <head>
        <title>Coordinates 1</title>
        <object id="SGWorld" classid="CLSID:3a4f91b1-65a8-11d5-85c1-0001023952c1" style="visibility:hidden;height:0 "></object>
        <script type="text/javascript">

        var popup = null;

        var coordHancock, pos;

        var time;
        function Init()
        {

            SGWorld.AttachEvent("OnFrame", onFrame);

            setTimeout(function () { SGWorld.DetachEvent("OnFrame", onFrame); }, 15000);

            time = new Date().getTime();

            coordHancock = SGWorld.Creator.CreatePosition(-71.07542, 42.34930, 232.0);

            SGWorld.Creator.CreateTextLabel(coordHancock, "Hancock Building",SGWorld.Creator.CreateLabelStyle());

            pos = SGWorld.Creator.CreatePosition(-71.10055, 42.31624, 350.0,0, 15.0); // x,y,height,height_type,yaw

            SGWorld.Navigate.SetPosition(pos);

            // Display a message to the user
            popup = SGWorld.Creator.CreatePopupMessage("Coordinate sample");
            popup.InnerText = "This sample shows how you can move a coordinate in one direction while aiming to another";
            popup.Align = "TopLeft";
            SGWorld.Window.ShowPopup(popup);
        }

        function onFrame()
        {
            var elapsedTime = (new Date().getTime() - time) / 1000 // elapsed time in seconds
            time = new Date().getTime();
            pos = pos.Move(400*elapsedTime, 15.0, 0.0).AimTo(coordHancock);   // 400 meters/sec

            SGWorld.Navigate.SetPosition(pos);
        }

        function Uninit()
        {
            if(SGWorld.Project.Name == "")
                return;
            if(popup)
                SGWorld.Window.RemovePopup(popup);
        }

        </script>
    </head>
    <body onload="Init();" onunload="Uninit()">
    </body>
</html>

5.以上效果叠加：

<html>
    <head>
        <title>Coordinates 5</title>
        <object id="SGWorld" classid="CLSID:3a4f91b1-65a8-11d5-85c1-0001023952c1" style="visibility:hidden;height:0 "></object>
        <script type="text/javascript" src="abspath.js"></script>
        <script type="text/javascript">

        var popup = null;

        var model     = null;

        var yaw = 45.0;
        var totalTime = 0;
        function Init()
        {
            SGWorld.AttachEvent("OnFrame", onFrame);
            setTimeout(function () { SGWorld.DetachEvent("OnFrame", onFrame); }, 10000); // remove event handler after 10 seconds
            time = new Date().getTime();

            model = SGWorld.Creator.CreateModel(SGWorld.Creator.CreatePosition(-71.10055, 42.31624, 125.0,0, 28), toAbspath("data/f16.xpc"), 1);

            labelF16 = SGWorld.Creator.CreateTextLabel(SGWorld.Creator.CreatePosition(0, 0), "F-16",SGWorld.Creator.CreateLabelStyle());

            // Display a message to the user
            popup = SGWorld.Creator.CreatePopupMessage("Coordinate sample");
            popup.InnerText = "This sample shows how, by manipulating coordinates, you can create a complex scene\r\n" +
                              "In this sample you can see how to:\r\n" +
                              "1. Move an object (F16)\r\n" +
                              "2. Make another object, a label in this case, to follow the first object\r\n" +
                              "3. Make the camera follow the first object while circling it";
            popup.Align = "TopLeft";
            SGWorld.Window.ShowPopup(popup);
        }


        function onFrame()   // elapsedTime is the time in seconds elapsed from the previous frame
        {
            var elapsedTime = (new Date().getTime() - time) / 1000 // elapsedTime is the time in seconds elapsed from the previous frame
            time = new Date().getTime();

            var modelPos = model.Position;

            modelPos.Roll = modelPos.Roll + 4.5;
            modelPos = modelPos.Move(700 * elapsedTime, modelPos.Yaw, modelPos.Pitch); // move the object in its current direction at a speed of 700 m/s

            if (totalTime > 6)
                modelPos.Pitch += 20*elapsedTime; // increase pitch by 20 degree per sec

            model.Position = modelPos;

            // Make the label object to be positioned 40 meters above (pitch = 90) the first object
            labelF16.Position = modelPos.Move(40.0, 0.0, 90.0);

            // Move the camera in relation to the first object while looking at it.
            yaw += 40.0*elapsedTime; // increase yaw by 40 degree per sec
            var cameraPos = modelPos.Move(700, yaw, 5).AimTo(modelPos);
            cameraPos.Roll = 0; // plane is rolling, but we do not want the camera to use this roll, so we zero it.
            SGWorld.Navigate.SetPosition(cameraPos);
            totalTime += elapsedTime;
        }

        function Uninit()
        {
            if(SGWorld.Project.Name == "")
                return;
            if(popup)
                SGWorld.Window.RemovePopup(popup);

        }

        </script>
    </head>
    <body onload="Init();" onunload="Uninit()">
    </body>
