Rendering is the process of generating a two-dimensional image of a three-dimensional scene, somewhat like taking a photograph with a camera, or filming with a motion picture camera.
Like photography, rendering requires that you determine a number of factors before you actually render the image. You need to
- Model the objects
- Assign shaders and textures to objects
- Optimize the scene
- Light the scene
- Set the size of the image to be produced
Rendering is an iterative and experimental process altering your environment to suit the needs of your rendering image.
