Blender use? texture in 3d mode?

I’m having a little trouble grasping the concept of 3d modeling. Am I to understand that while in “3d mode” or “edit mode” you cannot have the beautifully detailed images and spin it around to look from all angles? The texture and detail only comes after rendering a still image? Wouldn’t it be faster to draw an image than to create an entire scene in 3d to only take a 2d still? Has anyone successfully exported their models to video games? Do the textures export as well? I am having fun learning the program but need a purpose to stay motivated. I can’t seem to even find a video of a detailed model anywhere. Obviously I’m pretty confused. Thanks in advance…:eek:
