Computer graphic artists must have a good understanding of basic principles of lighting. Observational drawing helps artists understand how to depict the phenomena of light that we see in the natural world. However, designing a lighting scheme that looks good on a page or screen is quite a different skill than creating a representation of an existing lighting situation.
To show off their work most effectively, computer graphic artists must apply the lighting techniques developed in studio portraiture, theater, photography, and cinematography. This article outlines the basic concepts of lighting theory, and how to implement some real-world lighting techniques using the tools of 3D graphics software. It is an introductory article written to help emerging CG artists light their scenes effectively and with an eye for aesthetics.

The process of animation can be complex, so it’s critical to have a solid plan before you begin. If you don’t have a clear idea of where you're headed, it’s very difficult to get there.
Pre-production involves scriptwriting, storyboarding, and production planning. One important document in the planning phase is a shot list. A shot is an unbroken sequence of images that we see as continuous. Each shot begins and ends with a transition, such as a cut or a dissolve. A shot list is simply a spreadsheet that lists each shot, along with its camera, duration, description, and other pertinent information.

Aaron F. Ross, webmaster of Digital Arts Guild, has authored another series of training videos for lynda.com.
In Creating Particle and Fire Effects with Maya, Aaron F. Ross employs Maya particles and fluids to generate stunning special effects simulations, including exploding fireworks, tumbling snowflakes, and burning flames. Following a project-based approach, the course shows how to emit and render particles, write expressions to control and fine-tune effects, and animate and shade dynamic fluids. Tutorials on batch rendering and compositing in After Effects are also included. Exercise files accompany the course.
Topics include:
Laying out the scene
Sketching particles on a Live object
Emitting particles from particles
Connecting particles to Fields such as Gravity
Varying particle shader attributes
Modeling and shading for the Particle Instancer
Importing and instancing geometry onto particles
Randomizing particle rotation with Creation and Runtime Expressions
Adding Turbulence
Rendering depth of field with mental ray
Creating 3D Fluid containers
Emitting dynamic fluid attributes from an object
Animating a dynamic fluid
Using a fluid for atmosphere
Modulating light intensity with a noise expression |
