Summary
Apply images over polyfaces
Solution
In 6018 a new property MappedImages was added in vdPolyface and vdGroundSourface objects.
MappedImages is a collection of MappedImage object .You can apply one or more images
MappedImage object contains the following properties:
MaterialImage which is a vdImageDef previously added in vdDocument.Images
SourceRectangle which is define the sub-rectangle that is used to map the image over a surface.
if it is dRectangle.Empty (which is the default value) the whole image is mapped over the surface.
MaterialMatrix which is define the Matrix used for transformations from source rectangle to destination in World Coordinate System.
The MappedImages for a surface are drawn only when RenderMode is "RENDER"
Example of mapping 2 images in a vdPolyface object in C# :
vdPolyface pf = new vdPolyface();
pf.SetUnRegisterDocument(doc);
pf.setDocumentDefaults();
gPoints pts = new gPoints();
pts.Add(new gPoint(0, 0, 0));
pts.Add(new gPoint(1, 0, 0));
pts.Add(new gPoint(2, 0, 0));
pts.Add(new gPoint(0, 1, 0));
pts.Add(new gPoint(1, 1, 1));
pts.Add(new gPoint(2, 1, 0));
pts.Add(new gPoint(0, 2, 0));
pts.Add(new gPoint(1, 2, 0));
pts.Add(new gPoint(2, 2, 0));
pf.VertexList = pts;
Int32Array fl = new Int32Array();
//First face
fl.AddItem(1);fl.AddItem(2);fl.AddItem(5);fl.AddItem(4);fl.AddItem(-1);
//Second face
fl.AddItem(2);fl.AddItem(3);fl.AddItem(6);fl.AddItem(5);fl.AddItem(-1);
//Third face
fl.AddItem(4);fl.AddItem(5);fl.AddItem(8);fl.AddItem(7);fl.AddItem(-1);
//Forth face
fl.AddItem(5);fl.AddItem(6);fl.AddItem(9);fl.AddItem(8);fl.AddItem(-1);
pf.FaceList = fl;
vdImageDef img1 = doc.Images.Add(@"c:\images\image1.jpg");
vdImageDef img2 = doc.Images.Add(@"c:\images\image2.jpg");
//mapp a sub-rectangle of image1, (100, 50, 200, 150) pixels , so that the lower-left point of the image is transormed into 0.3,0.3 world position and the image mapped width is become 1.7 drawing units
pf.MappedImages.AddItem(new vdMappedImage(img1, new gPoint(0.3, 0.3, 0), Globals.DegreesToRadians(0.0d), 1.7d, new VectorDraw.Render.vdRectangle(100, 50, 200, 150)));
//mapp the whole rectangle of image2 so that the lower-left point of the image is transormed into 0.0,1.3 world position and the image mapped width is become 2.0 drawing units
pf.MappedImages.AddItem(new vdMappedImage(img2, new gPoint(0, 1.3, 0), Globals.DegreesToRadians(0.0d), 2.0d, VectorDraw.Render.vdRectangle.Empty));
doc.ActiveLayOut.Entities.AddItem(pf);
doc.CommandAction.View3D("RENDER");
Example of mapping 2 images in a vdGroundSouface object in C#
vdGroundSurface sf = new vdGroundSurface();
sf.SetUnRegisterDocument(doc);
sf.setDocumentDefaults();
vdImageDef img1 = doc.Images.Add(@"c:\images\image1.jpg");
vdImageDef img2 = doc.Images.Add(@"c:\images\image2.jpg");
//mapp a sub-rectangle of image1, (100, 50, 200, 150) pixels , so that the lower-left point of the image is transormed into 0.3,0.3 world position and the image mapped width is become 1.7 drawing units
sf.MappedImages.AddItem(new vdMappedImage(img1, new gPoint(0.3, 0.3, 0), Globals.DegreesToRadians(0.0d), 1.7d, new VectorDraw.Render.vdRectangle(100, 50, 200, 150)));
//mapp the whole rectangle of image2 so that the lower-left point of the image is transormed into 0.0,1.3 world position and the image mapped width is become 2.0 drawing units
sf.MappedImages.AddItem(new vdMappedImage(img2, new gPoint(0, 1.3, 0), Globals.DegreesToRadians(0.0d), 2.0d, VectorDraw.Render.vdRectangle.Empty));
gPoints pts = new gPoints();
pts.Add(new gPoint(0, 0, 0));
pts.Add(new gPoint(1, 0, 0));
pts.Add(new gPoint(2, 0, 0));
pts.Add(new gPoint(0, 1, 0));
pts.Add(new gPoint(1, 1, 1));
pts.Add(new gPoint(2, 1, 0));
pts.Add(new gPoint(0, 2, 0));
pts.Add(new gPoint(1, 2, 0));
pts.Add(new gPoint(2, 2, 0));
sf.Points = pts;
doc.ActiveLayOut.Entities.AddItem(sf);
doc.CommandAction.View3D("RENDER");

In Visual Basic 6.0 you can do it this way :
Private Sub Form_Load()
' You need to add the VectorDraw.Professiona.tlb, VectorDraw.Geometry.tlb and VectorDraw.Render.tlb in the project's references
