How do I display the imported 3D model in the picture of the MFC dialog?

What you're talking about is more complicated, and you can't do it in a day or two, unless you've learned DirectX (read the file with a function like D3DxLoadMeshFromFile provided by Microsoft, and then display it with the relevant DirectX function, and it takes at least 1000 lines to do this**).

As for the geldlgitem you mentioned, it's very simple, it's to get the widget with the resource number idc render.

What is the urgency, how long?

Why do you put it in the picture control? . . It can be divided into two steps.

1.How to use OpenGL in MFC

2.How to display 3DS models with OpenGL.

The first time I used the DEX control to develop the WinFrom program, now I encounter the top menu of the ribgbonmain main form is hidden by default, and it is displayed only when I click on the ribbon. This saves space in the interface. But I can't find a place to set it.

And it has this effect in the WinForm program where other people are sitting.

No one can give you this question.

1.Different 3D model files, different definition formats, and analysis are not the same.

2.The 3D model has nothing to do with MFC.

You can look for information on game engines, and it's not just a few words that can be said clearly. Search stool pie.

What format is the ** you want to add? Only BMP format can be added. You add ** to the resource, then right-click on the property of the picture control and select which bitbmp to choose. Then just find the one you added.

I recommend you read Sun Xin's MFC book.

Dynamic insertion is still in existence when the dialog is displayed???

If the ipl is a cmainframe member variable, then, in another dialog:

cmainframe *)afxgetmainwnd())ipl

You can get this variable and display it.

Your ** use OpenCV to do it, check if your IDC Picture1 is included in CmainFrame

In this class, if not, there is no way to pass the message to the control you want to display**, in this case, you display the opencv library according to the name of your dialog box when there is a ready-made function that can be called, I don't remember exactly what it is, I don't do VC now, but I used it before.

Besides, the picture control in MFC can only display 256 colors**, if you want to display 16W colors or higher, you need to draw it yourself, and the Windows API function provides it, which is also very efficient.

Two kinds of data?

Let the data of the linked list be a mechanism type, and the 3-n kinds of data can also be stored and can also be stored as a pointer to another linked list.

That kind of linked list becomes a tree.

Is it c's? I guess you didn't write anything in the page repaint, haha, did you write something in paint? Check it out, maybe it will solve your problem.
