Export with 3D options

Export with 3D options

Few options were introduced to export 3D models to PDF/raster from corresponding FBX, OBJ, STL formats.

Here are the examples of the 3D scene from different viewpoints:

ObserverPoint property allows to rotate the 3D scene according to specified angles around axis. This example shows the code and export result using some arbitrary rotation angles.

using (Image cadImage = Aspose.CAD.Image.Load(inputFileName))
{
    CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions()
    {
        PageWidth = 5000,
        PageHeight = 5000,
        DrawType = CadDrawTypeMode.UseObjectColor,
        ObserverPoint = new ObserverPoint(15, 5, 5),
    };

    PdfOptions pdfOptions = new Aspose.CAD.ImageOptions.PdfOptions();
    pdfOptions.VectorRasterizationOptions = rasterizationOptions;

    cadImage.Save(outputFileName, pdfOptions);
}

Changing the ObserverAngle to ObserverPoint = new ObserverPoint(5, 60, 0) allows to rotate the scene.

The other RenderMode3D property allows to specify how export result should be presented. There are 3 modes: Solid (the default), Wireframe, and SolidWithEdges.

The example below allows to create wireframe model for the spherical object.

using (Image cadImage = Aspose.CAD.Image.Load(fileName))
{
    CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions()
    {
        PageWidth = 5000,
        PageHeight = 5000,
        DrawType = CadDrawTypeMode.UseObjectColor,

        RenderMode3D = RenderMode3D.Wireframe
    };

    PdfOptions pdfOptions = new Aspose.CAD.ImageOptions.PdfOptions();
    pdfOptions.VectorRasterizationOptions = rasterizationOptions;

    cadImage.Save(outputFileName, pdfOptions);
}

The example below shows the difference between Solid and SolidWithEdges modes.
