Creating a 3D Object with MPR View Tutorial

This tutorial teaches you how to create a 3D object and render the three MPR orthogonal slices ( Axial, Sagittal and Coronal) on a cell window.

Start with the project you created in Creating A 3D Object.
Run the program now and you will see a 2x2 layout with one of the slots filled with a 3D object.

Now, add the three MPR cells:
Create a new instance of the MedicalViewerMPRCell and change its properties to accommodate your needs. For this demonstration we will create the axial cell. To do this, add the following lines to the bottom of the InitClass method:
[Visual Basic]

            ' Create a new cell that will hold the axial frame.
            Dim axialCell As MedicalViewerMPRCell = New MedicalViewerMPRCell()
            ' adjust some properties to view the cross hair.
            axialCell.ShowMPRCrossHair = True
            axialCell.DistinguishMPRByColor = True

[C#]

            // Create a new cell that will hold the axial frame.
            MedicalViewerMPRCell axialCell = new MedicalViewerMPRCell();
            // adjust some properties to view the cross hair.
            axialCell.ShowMPRCrossHair = true;
            axialCell.DistinguishMPRByColor = true;

Assign the axial cell to the medical 3D control through the AxialFrame property. To do this, add the following line at the bottom of the InitClass method:
[Visual Basic]

            ' Assign this cell (axialCell) to the AxialFrame property of the Medical 3D control
            control3D.AxialFrame = axialCell

[C#]

            // Assign this cell (axialCell) to the AxialFrame property of the Medical 3D control
            control3D.AxialFrame = axialCell;

Finally, add the created instance to the viewer. To do this, add the following line at the bottom of the InitClass method:
[Visual Base]

            ' add the axial cell to the viewer
            viewer.Cells.Add(axialCell)

[C#]

            // add the axial cell to the viewer
            viewer.Cells.Add(axialCell);

Repeat the steps (3), (4) and (5) above, to create the sagittal and coronal cells. However, note that in step (4), you must assign the sagittal cell to the SagittalFrame property in the Medical3DControl and the coronal cell to the CoronalFrame property of the Medical 3D control.

The InitClass() should look as shown below:
[Visual Basic]

            Private Sub InitClass()
                 RasterSupport.SetLicense(RasterSupportType.Dicom, " Your Dicom Key");
                 RasterSupport.SetLicense(RasterSupportType.Medical, "Your Medical Key");
                 RasterSupport.SetLicense(RasterSupportType.Medical3d, "Your Medical 3D Key");
                 
                 // Create a new instance of the Codecs class, which will be used to load the images.
                 RasterCodecs _codecs = new RasterCodecs();
                 // Create a new instance of the Medical Viewer. The layout will be divided to 2X2.
                 MedicalViewer viewer = new MedicalViewer(2, 2);
                 // Fit the view to the whole form
                 viewer.Dock = DockStyle.Fill;
                 // Create the 3D control that will hold the 3D object.
                 Medical3DControl control3D = new Medical3DControl();
                 control3D.AddAction(MedicalViewerActionType.WindowLevel);
                 control3D.SetAction(MedicalViewerActionType.WindowLevel, MedicalViewerMouseButtons.Left, MedicalViewerActionFlags.Active);
                 Medical3DObject object3D = new Medical3DObject();
                 // Add the newly created 3D object to the control.
                 control3D.ObjectsContainer.Objects.Add(object3D);
                 object3D.Image = _codecs.Load(@"C:\Users\Public\Documents\LEADTOOLS Images\image1.dcm");
                 // Add the cell above to the MedicalViewer.
                 viewer.Cells.Add(control3D);
                 Controls.Add(viewer);
                 
                 // Create a new cell that will hold the axial frame.
                 MedicalViewerMPRCell axialCell = new MedicalViewerMPRCell();
                 // adjust some properties to view the cross hair.
                 axialCell.ShowMPRCrossHair = true;
                 axialCell.DistinguishMPRByColor = true;
                 
                 // Assign this cell (axialCell) to the AxialFrame property of the Medical 3D control
                 control3D.AxialFrame = axialCell;
                 
                 // add the axial cell to the viewer
                 viewer.Cells.Add(axialCell);
                 
                 // Create a new cell that will hold the coronal frame.
                 MedicalViewerMPRCell coronalCell = new MedicalViewerMPRCell();
                 
                 // adjust some properties to view the cross hair.
                 coronalCell.ShowMPRCrossHair = true;
                 coronalCell.DistinguishMPRByColor = true;
                 
                 // Assign this cell (coronalCell) to the CoronalFrame property of the Medical 3D control
                 control3D.CoronalFrame = coronalCell;
                 
                 viewer.Cells.Add(coronalCell);
                 
                 // Create a new cell that will hold the sagittal frame.
                 MedicalViewerMPRCell sagittalCell = new MedicalViewerMPRCell();
                 
                 // adjust some properties to view the cross hair.
                 sagittalCell.ShowMPRCrossHair = true;
                 sagittalCell.DistinguishMPRByColor = true;
                 
                 // Assign this cell (sagittalCell) to the SagittalFrame property of the Medical 3D control
                 control3D.SagittalFrame = sagittalCell;
                 
                 viewer.Cells.Add(sagittalCell);
                 
                 // Add the viewer as a child to the form.
                 this.Controls.Add(viewer);
            End Sub

             }

Run the program and you should see four cells: One for the 3D object and the other three for Axial, Sagittal and Coronal cells.
