The document discusses lighting in 3D animation software Blender. It defines visible light and how light interacts with objects by reflecting or being absorbed. It then describes different types of lights that can be used in Blender like point lamps, sun lamps, spot lamps, and area lamps to simulate different real-world light sources. It also discusses using color temperature to define light sources as being warm or cool colors. Additional resources on lighting in Blender are provided.

1. 3D Animation
With Blender

2. What is Light?
Light sources in Blender
Lighting Rigs

3. Visible light is part of the electromagnetic spectrum. It
is energy emitted from a flame, light globe, the sun,
etc…
When light hits an object some bounces off and the
rest is absorbed
What we see is the reflected light

4. Colour temp is a simple
way of defining a light
source
Warm colours are below
3000°K
Cool colours are above
5000°K

5. Point Lamp
Simulates an omni-directional light
Sun Lamp (AKA Directional light)
Simulates the sun with parallel rays of sunlight
Spot Lamp
Simulates a spotlight
Hemi Lamp
Simulates a headlight-like lamp
Area Lamp
Simulates multiple lights
