How can I create some 3D Objects
Solution
You can create 3D objects in VDF by using some basic functionality and objects.
A. Using CommandAction methods like :
private void button1_Click(object sender, EventArgs e)
{
Doc = vdFramedControl1.BaseControl.ActiveDocument;
gPoints pts = new gPoints(); pts.Add(new gPoint(-16, 0)); pts.Add(new gPoint(-14, 0)); pts.Add(new gPoint(-14, 3)); pts.Add(new gPoint(-16, 3));
Doc.CommandAction.Cmd3dFace(pts); // create a 3D face from 4 points
pts = new gPoints(); pts.Add(new gPoint(-12, 0, 0)); pts.Add(new gPoint(-10, 0, -1)); pts.Add(new gPoint(-8, 0, 0)); pts.Add(new gPoint(-5, 0, 0));
pts.Add(new gPoint(-12, 3, 1)); pts.Add(new gPoint(-10.5, 2.7, -1)); pts.Add(new gPoint(-8, 3, 0)); pts.Add(new gPoint(-5, 3.2, 0));
pts.Add(new gPoint(-12, 6, 0)); pts.Add(new gPoint(-10.5, 5.7, 4)); pts.Add(new gPoint(-8, 6, 1)); pts.Add(new gPoint(-5, 5.8, 1));
pts.Add(new gPoint(-12.5, 9, -0.5)); pts.Add(new gPoint(-10.5, 9.2, 2)); pts.Add(new gPoint(-8, 9.1, 0)); pts.Add(new gPoint(-5, 8.8, 0));
Doc.CommandAction.Cmd3DMesh(4, 4, pts); // create a vdPolyface MESH that is made by 16 points
Doc.CommandAction.CmdSphere(new gPoint(0,0,0),3.0d,32,16); // create a sphere
Doc.CommandAction.CmdCone(new gPoint(7, 0, 0), 3.0d, 1.0d, 10.0d, 30);// create a cone
Doc.CommandAction.CmdBox3d(new gPoint(11, 0, 0), 4.0d, 2.0d, 3.0d, 0.0d); // create a orthogonal 6-side box
Doc.CommandAction.CmdTorus(new gPoint(19, 0), 2.0D, 0.5D, 30, 20); // create a torus
}
B. By code using the vdPolyface object :
private void button2_Click(object sender, EventArgs e)
{
Doc = vdFramedControl1.BaseControl.ActiveDocument;
int[] array_faces = {1, 2, 5, 4, 116, // connect vertexes 1, 2, 5 and 4 to one face with color 116
7, 8, 3, 3, 116,
7, 12, 3, 3, 116,
8, 3, 6, 9, 116,
3, 12, 11, 6, 116,
6, 9, 10, 10, 116,
6, 10, 11, 11, 116,
7, 8, 14, 13, -1,
14, 15, 25, 8, -1,
15, 16, 9, 25, -1,
9, 10, 17, 16, -1,
17, 18, 11, 10, -1,
11, 26, 19, 18, -1,
12, 26, 19, 20, -1,
7, 12, 20, 13, -1,
20, 19, 23, 24, -1,
14, 15, 22, 21, -1,
15, 19, 23, 22, -1,
14, 20, 24, 21, -1,
21, 22, 23, 24, -1,
13, 14, 20, 20, 2,
16, 17, 18, 18, 2,
15, 16, 18, 19, 2};
Int32Array faces = new Int32Array(array_faces);
gPoints pts = new gPoints();
pts.Add(2, 0, 0);
pts.Add(3, 0, 0);
pts.Add(1, 0, 1);
pts.Add(2.2, 0, 1);
pts.Add(3.8, 0, 1);
pts.Add(5, 0, 1);
pts.Add(0, 0, 2);
pts.Add(1, 1, 2);
pts.Add(5.5, 1, 2);
pts.Add(7, 0, 2);
pts.Add(5.5, -1, 2);
pts.Add(1, -1, 2);
pts.Add(-0.5, 0, 3);
pts.Add(0.5, 1.5, 3);
pts.Add(3.5, 1.7, 3);
pts.Add(6, 1.5, 3);
pts.Add(8, 0, 3);
pts.Add(6, -1.5, 3);
pts.Add(3.5, -1.7, 3);
pts.Add(0.5, -1.5, 3);
pts.Add(0.5, 1, 4);
pts.Add(3, 1, 4);
pts.Add(3, -1, 4);
pts.Add(0.5, -1, 4);
pts.Add(3.25, 1, 2);
pts.Add(3.25, -1, 2);
vdPolyface pFace = new vdPolyface(Doc, pts, faces); // create the vdPolyface and
Doc.Model.Entities.AddItem(pFace); // add it to the document
Doc.CommandAction.View3D("VISW");
Doc.CommandAction.View3D("SHADE");
}
C. Using Generate3DPathSection :
private void button3_Click(object sender, EventArgs e)
{
Doc = vdFramedControl1.BaseControl.ActiveDocument;
//create an oval tube
vdEllipse ci = new vdEllipse(Doc, new gPoint(), 0.03, 0.02, 0, 0, 0); // Doesn't need to be in the document
Vertexes verts = new Vertexes();
verts.Add(0, 0, 0, 0); verts.Add(0, 1, 0, -0.5); verts.Add(1, 1, 0, 0.2); verts.Add(1, 2, 0, 0);
vdPolyline pline = new vdPolyline(Doc, verts);// Doesn't need to be in the document
//We will use a polyline as path and an ellipse as section which ellipse is going to go round the polyline and create the polyface needed.
vdPolyface pface = new vdPolyface();
pface.SetUnRegisterDocument(Doc);
pface.setDocumentDefaults();
pface.setDocumentDefaults();
pface.Generate3dPathSection(pline, ci, new gPoint(0, 0.0, 0.0), 0, 1);
Doc.Model.Entities.AddItem(pface); // add the polyface to the document.
}
D. Using GroundSurface :
Check the "AddEntities Sample" and the GroundSurface button click code there.
E. By cutting (slicing) a existing polyface :
private void button4_Click(object sender, EventArgs e)
{
Doc = vdFramedControl1.BaseControl.ActiveDocument;
Doc.New();
if (Doc.CommandAction.CmdSphere(new gPoint(0, 0, 0), 3.0d, 32, 16)) // create a sphere
{
vdPolyface pface = Doc.Model.Entities[Doc.Model.Entities.Count - 1] as vdPolyface;
if (pface != null)
{
pface.PenColor.FromSystemColor(Color.PowderBlue);
pface.Slice(new gPoint(-0.5, 0, 0), new Vector(-1, 0, 0), true, true);
pface.Slice(new gPoint(0, -1, 0), new Vector(-1, -1, 0), false,true); // do not cover this slice
Doc.CommandAction.View3D("SHADE");
}
}
}
F. By using a vdPolyHatch object with thickness and the ToMesh() function to convert it to a vdPolyface object, like :
private void button5_Click(object sender, EventArgs e)
{
double dLength = 400; double dDInterior = 100; double dDExterior = 200; double dSpecial = 10;
double dHelp = dDInterior - dSpecial;
Doc = vdFramedControl1.BaseControl.ActiveDocument;
Doc.New();
vdPolyline oPLine = new vdPolyline(); oPLine.SetUnRegisterDocument(Doc); oPLine.setDocumentDefaults();
oPLine.VertexList.Add(new Vertex(dDExterior / 2, 0, 0, 1));
oPLine.VertexList.Add(new gPoint(-dDExterior / 2, 0, 0));
oPLine.VertexList.Add(new Vertex(-dDExterior / 2, 0, 0, 1));
oPLine.Flag = VectorDraw.Professional.Constants.VdConstPlineFlag.PlFlagCLOSE;
vdPolyline oPLine2 = new vdPolyline(); oPLine2.SetUnRegisterDocument(Doc); oPLine2.setDocumentDefaults();
oPLine2.VertexList.Add(new Vertex(dDInterior / 2, -dSpecial / 2, 0, -1));
oPLine2.VertexList.Add(new gPoint(-dDInterior / 2, -dSpecial / 2, 0));
oPLine2.Flag = VectorDraw.Professional.Constants.VdConstPlineFlag.PlFlagCLOSE;
vdPolyline oPLine3 = new vdPolyline(); oPLine3.SetUnRegisterDocument(Doc); oPLine3.setDocumentDefaults();
oPLine3.VertexList.Add(new Vertex(dDInterior / 2, dSpecial / 2, 0, 1));
oPLine3.VertexList.Add(new gPoint(-dDInterior / 2, dSpecial / 2, 0));
oPLine3.Flag = VectorDraw.Professional.Constants.VdConstPlineFlag.PlFlagCLOSE;
VectorDraw.Professional.vdCollections.vdCurves curves_Outer = new VectorDraw.Professional.vdCollections.vdCurves();
curves_Outer.AddItem(oPLine);
VectorDraw.Professional.vdCollections.vdCurves curves_Inside = new VectorDraw.Professional.vdCollections.vdCurves();
curves_Inside.AddItem(oPLine2);
curves_Inside.AddItem(oPLine3);
//'create polyhatch
vdPolyhatch onehatch = new vdPolyhatch();
onehatch.SetUnRegisterDocument(Doc);
onehatch.setDocumentDefaults();
onehatch.PolyCurves.AddItem(curves_Outer);
onehatch.PolyCurves.AddItem(curves_Inside);
onehatch.HatchProperties = new VectorDraw.Professional.vdObjects.vdHatchProperties(VectorDraw.Professional.Constants.VdConstFill.VdFillModeSolid);
onehatch.Thickness = dLength;
//'create polyhatch
vdPolyface oPFace = onehatch.ToMesh(0);
oPFace.PenColor.FromSystemColor(Color.Purple);
Doc.Model.Entities.AddItem(oPFace);
Doc.CommandAction.View3D("VISE");
Doc.CommandAction.View3D("SHADE");
Doc.Model.ZoomExtents();
}
