digitalVideoType
Syntax
member(whichCastMember).digitalVideoType
the digitalVideoType of member whichCastMember
Description
Cast member property; indicates the format of the specified digital video. Possible values are
#quickTime or #videoForWindows.
This property can be tested but not set.
Example
The following statement tests whether the cast member Today’s Events is a QuickTime or AVI
(Audio-Video Interleaved) digital video and displays the result in the Message window:
put member("Today’s Events").digitalVideoType

direction
Syntax
member(whichCastmember).modelResource(whichModelResource).\
emitter.direction
Description
3D emitter property; a vector that indicates the direction in which the particles of a particle
system are emitted. A particle system is a model resource whose type is #particle.
The primary direction of particle emission is the vector set by the emitter’s
direction property.
However, the direction of emission of a given particle will deviate from that vector by a random
angle between 0 and the value of the emitter’s
angle property.
Setting direction to vector(0,0,0) causes the particles to be emitted in all directions.
The default value of this property is
vector(1,0,0).
Example
In this example, ThermoSystem is a model resource whose type is #particle. This statement sets
the
direction property of ThermoSystem’s emitter to vector(1, 0, 0), which causes the particles
of ThermoSystem to be emitted into a conical region whose axis is the X axis of the 3D world.
member("Fires").modelResource("ThermoSystem").emitter.\
direction = vector(1,0,0)
