3D Lighting Techniques in Animation

• There are several wells established in 3D
  lighting techniques, and it is often
  predetermined by type of an environment, which
  technique is most appropriate in the case.
• Some 3D Lighting techniques in animation work
  well in an interior environment and make little
  sense in exterior modeling.

1. Spot Light

• There are target spotlights and free sports, and
  it means that they have no target spotlights and
  free sports, which means that they have no target
  objects. It is often used to simulate light
  fixture.
• Example Desk lamps or streetlights as it casts a
  focused ray of light.

2. Area Light

• Area lights emit light within a set boundary of a
  certain size and shape.
• This type of light source is often used in the
  visualization of architectural models as well as
  in product lightning.
• Area lights produce soft-edged shadows that make
  the rendering look more realistic.

3. Directional Light

• It is the opposite of Omni light, and it presents
  a very distant source of light.
• Directional rays go parallel in a single
  direction.
• This type of 3D lighting is used to simulate the
  sunlight.

• To change the illumination of the scene, you can
  adjust the position or color of light and rotate
  the directional light source.

4. Volume Light

• It casts rays in all directions from a certain
  point.
• A volume light has a specified shape and size.
• This volumetric light illuminates only surfaces
  within the set volume.
• Volume Light provides the effect of smoke, fog,
  and so on.

5. Omni Light

• A point light casts rays in every direction from
  a single, small source in the 3D environment.
• It has no specific shape and size. Point lights
  can add fill lighting effect to a 3D scene, as
  well as simulate any light source like Christmas
  tree lights, candles or others.

6. Ambient Light

• It casts soft rays in every direction, though it
  has no specific directionality and emits no
  shadow on the ground.
• It can be compared to dusk after the sunset.
• Often it sources in addition to the color of the
  main light source for a 3D scene.

• Usage of 3D lighting technique explained above is
  extensive, from simple point studio to complex
  animated scenes.
• 3D designers and animators always use several
  lighting techniques in animation to light a 3D
  scene.
• It is almost impossible to find a scene with only
  directional lights, or only point lights, etc. We
  can say that certain light types are good for
  certain 3D scenes.
