In vs2017 build a c # WPF project, I'd like to have two. Obj model can be put in the same interface, the two models can be individually controlled rotation, and can be stacked together, and how to implement this background, I now can only be divided into two parts in an interface control, don't know how to put together the

CodePudding user response:

As long as you are the coordinates of the stack can be, but need to pay attention to the element is in two different space

CodePudding user response:

In Model3DGroup can Model3DGroup. Children. The Add (model); Methods add other Model3DGroup class

CodePudding user response:

Is only, for example, a 3 d model, for example, in the Grid, make two Grid, each new inside a Preview_Model, set a Grid position is overlap,
