radius

Syntax

modelResourceObjectReference.radius

member(whichCastmember).modelResource(whichModelResource).radius

Description

3D model property; when used with model resource of type #sphere or #cylinder, allows you to

get or set the radius of the model.

The

radius property determines the sweep radius used to generate the model resource. This

property’s value must always be set to greater than 0.0, and has a default value of 25.0.

Example

This example shows that the radius of the model resource Sphere01 is 24.0:

put member("3D World").modelResource("Sphere01").radius

-- 24.0

ramNeeded()

Syntax

ramNeeded (firstFrame, lastFrame)

Description

Function; determines the memory needed, in bytes, to display a range of frames. For example,

y o u c a n t e s t t h e s i z e o f f r a m e s c o n t a i n i n g 3 2 - b i t a r t w o r k : i f

ramNeeded() is larger than freeBytes(),

then go to frames containing 8-bit artwork and divide by 1024 to convert bytes to kilobytes (K).

Examples

This statement sets the variable frameSize to the number of bytes needed to display frames 100 to

125 of the movie:

put ramNeeded (100, 125) into frameSize

This statement determines whether the memory needed to display frames 100 to 125 is more

than the available memory, and, if it is, branches to the section using cast members that have

lower color depth:

if ramNeeded (100, 125) > the freeBytes then play frame "8-bit"
