How can I do an isometric 3d Graph.

Is any way to attach files ?

Hi QuijoteMX,

You can do something as in the All Features\Welcome!\Axes\Isometric Axes example at the features demo, available at TeeChart's program group.

You can post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thank you for your response.

I'm using .SetIsometric .Left.Index, .Bottom.Index; but what about the third axis, right depth for instance. My problem is a 3d box drawing where the depth dimension does'nt look proportional to others.

SetIsometric method works just for 2d graphs isn't it?

Hi QuijoteMX,

Yes, but you could try implementing your own MakeIsoAxis method as shown here adding support for depth axis.

Hi Narcis!

I'm working in VB6, the code you have sent is in C isn't it? Could it be converted almost as is or there are some issues that are diferent?

Besides, the setIsometric method provided by tChart works on left and bottom axes. The procedure you are referring to does the same. What about the depth axis.

Hi QuijoteMX,

No, that code is in Delphi but there shouldn't be much problems porting it to VB6.

Yes, SetIsometric only uses horizontal and vertical axes (by default left and bottom), you should add support for depth axis here.

If you have any problem porting the code please let us know.

Hi Narcis!

I'm having problems port the code to vb6. What´s the function getDeviceCaps?

The concept is clear making Left (y's) and bottom (x's) axis isometric. But what screen.dimension would apply for the depth(z's) axis.

Have you done something alike before? (3D isometric axis)

Hi QuijoteMX,

Could you try the following code? It seems to work fine here. And please, feel free to suggest any improving modification.

I implemented the code in my application and boosted it.

The code below is the core of the functionality I'm looking for.

It works fairy well but really not as intended. For example:
1. MakingIsoAxis don't produce any effect if it is invoked in the same
procedure where the graphic is done. If you code it as an independent
event it does.
2. If you click several times the command1 button the graph is shrunk
each time. The drawing looks Isometric once the graph stops shrinking.
3. I've added a teecommand control to allow rotation and some other
settings. When you use the rotation tool, the graphic goes out of
out proportion.

Well, that's about Isometric axis.

The walls of the box are drawn using pont3D series. My real intention is
to draw them as solid walls. I can draw horizontal and tilted planes using
surface3D but how to draw vertical planes (xy and yz planes)

I hope you could help me.

Thanks a lot

And regarding the problem of painting the walls of the box. Here there is an example of how you could paint two planes. You shouldn't find problems in implementing the others:

Code: Select all

Private Sub TChart1_OnAfterDraw()
  If TChart1.SeriesCount = 9 Then
    With TChart1
      .Canvas.Brush.Color = vbWhite
      .Canvas.Brush.Style = bsSolid
      .Canvas.BackMode = cbmOpaque
    
      .Canvas.PlaneFour3D .Series(1).CalcXPos(3), .Series(1).CalcYPos(3), _
                          .Series(1).CalcXPos(0), .Series(1).CalcYPos(0), _
                          .Series(1).CalcXPos(1), .Series(1).CalcYPos(1), _
                          .Series(1).CalcXPos(2), .Series(1).CalcYPos(2), _
                          .Series(1).asPoint3D.CalcZPos(3), .Series(1).asPoint3D.CalcZPos(3)

      .Canvas.Plane3D .Series(1).CalcXPos(3), .Series(1).CalcYPos(3), _
                      .Series(2).CalcXPos(2), .Series(2).CalcYPos(2), _

Hi Narcis!

I made a first down, but I'm still in yard number 20.

The code I've added implements your recommendations. But I'm far away of the functionality I'm looking for.

I've drawn all the surfaces of the box using 3dpoint series and looks fine but I don't get the oblique planes to look opaque.

could you help me ...

Thank you in advance ...

Hi QuixioteMx,

Here is how I would draw the first two planes. Note that now the point series is not needed but I calculate the points in the same way.

Code: Select all

  btapa = Ancho / 2
