3D APIs

Last week I dowloaded Microsoft DirectX SDK to attempt to mess around with 3D programming, and possibly make my own game. What I quickly learned was that DirectX was very confusing and difficult. I did several tutorials, and it seems like everything you want to do requires different code, nothing is the same from program to program. Why can't they make a 3D API that is just as easy to use as C# windows programming? Maybe I will make this my life long "for fun" project. My "vision" is to have code that would look something like this:

C# code

mesh myMesh = ("C://myDocs/mesh.obj");
camera myCamera = new camera;

scene myScene = (myCamera(X,Y,Z)), (myMesh(X,Y,Z));

render(24fps).myScene;

X,Y,Z would be the location of the object.
