Lighting Techniques in the 3D World
There are literally hundreds of different techniques for illuminating your scene. A whole book could be devoted to just demonstrating lighting options. While it is not possible to cover all lighting techniques here, there are some hard and fast techniques that work well. A common mistake is to pound all the lights you think you need right into a scene. This might work if you build similar scenes all the time and have discovered a lighting method that works best all the time. Because most animators build and work with all sorts of different scenes, often little commonality exists between lighting setups.Simulating Light Fixtures in the 3D World
The light casting portion of a light fixture can be represented in many ways. For an example that utilizes new features, examine a lamp with a lamp shade. Creating a realistic light source like this with the original your 3D application would have been next to impossible.
You can use your 3D application to create a black-and-white image that you might normally use an expensive 2D paint software for. In the exercises, you created simple 2D and 3D geometry, applied black-and-white materials, and rendered the image to a bitmap to be used in a new scene.Underpainting – The First Step to a Work of Art
Underpainting – The Concept Underpainting is the fundamental painting step in which first layer of paint is applied as a base on the surface of an artwork. Usually monochromatic, it helps reduce the diluting effect of the white canvas and allows the work to radiate its true colors.Light Colors in the 3D World
Most of the light that we encounter is tinted with a color. Indoor lighting, especially fluorescent lighting, is usually perceived to be white, whereas incandescent lights are perceived to be a bright beige color. Note that this is the color that is perceived if you are inside looking in. If you were staring into a building at night that was illuminated by fluorescent lights, they would appear to be more bluish-green. This is due to the colors your eye perceives based on the light entering it
