The image above was created using a 3D rendering program. Many programs have this capability - Photoshop, Illustrator, Cinema 4d, Maya, etc., each with varying degrees of achievable realism. Contrary to what many people think - - as you begin to create more complex shapes, the computer does not "draw" the shape for you. The artistry comes in controlling the infinite number of design choices - composition, color, texture, lighting, etc., as well as the actual "drawing" of the shapes. These are the same decisions you would make if using any media. The obvious difference is in the ease with which you are able to edit the scene after it has been created. I posted this today to show an example of the variety of skill sets available to today's artists.
