Cameras

By default, your scene already has one camera You add more cameras by hitting “Shift-A” ( 叫出

彈跳選單 ), like creating all other objects discussed up until now

To change which camera is active, you need to select that camera and press “Ctrl” and number pad “0”. This changes the active camera.

Lighting Types and Settings Most scenes usually require 3-4

lamps. Be careful not to use too many lamps!

The different types of lamps available for you to use are as follows:

Point- Basic Blender Lamp- shines all directions.

Sun- Provides even angle of light, regardless of placement from objects.

Spot- Shines a direct angle of light.

Hemi- A wider light, much like area lights.

Area- Provides large area lighting (like a classroom). Can be scaled.

Lighting Types and Settings

In traditional Blender rendering, only spotlights are able to cast shadows. However, with Ray-tracing (discussed in a later chapter) all lamps can cast shadows.
