Orbit

In This Topic

The orbit function in the CADCamera class allows users to move the camera on a plane by a given angle, while looking at and keeping the same distance from a set point.

The following Orbit sample illustrates how you use the orbit function to rotate around horizontal and vertical axes:

C#	Copy Code
using System.IO; using ImageGear.Formats; using ImageGear.Formats.CAD; public static void CameraOrbit(string path, double radX, double radY) { ImGearCADPage page = null; // Load the file. using (FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read)) { page = (ImGearCADPage)ImGearFileFormats.LoadPage(fileStream); } // Orbit the camera page.Camera.Orbit(radX, radY); }

Copy Code

{
    ImGearCADPage page = null;

    // Load the file.
    using (FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read))
    {
        page = (ImGearCADPage)ImGearFileFormats.LoadPage(fileStream);
    }

    // Orbit the camera
    page.Camera.Orbit(radX, radY);
}

VB.NET	Copy Code
Imports System.IO Imports ImageGear.Formats Imports ImageGear.Formats.CAD Public Sub CameraOrbit(path As String, radX As Double, radY As Double) Dim page As ImGearCADPage ' Load the file. Using fileStream As New FileStream(path, FileMode.Open, FileAccess.Read) page = ImGearFileFormats.LoadPage(fileStream) End Using ' Orbit the camera page.Camera.Orbit(radX, radY) End Sub

VB.NET

Copy Code

Imports System.IO
Imports ImageGear.Formats
Imports ImageGear.Formats.CAD

Public Sub CameraOrbit(path As String, radX As Double, radY As Double)
    Dim page As ImGearCADPage

    ' Load the file.
    Using fileStream As New FileStream(path, FileMode.Open, FileAccess.Read)
        page = ImGearFileFormats.LoadPage(fileStream)
    End Using

    '  Orbit the camera
    page.Camera.Orbit(radX, radY)
End Sub
