Measurement Measurement

Units | Scale Scale | Object Manipulation

To effectively create 3D objects, you should know the measurements of the environment in which they will be used.

Units

Measurement in RenderWare and Active Worlds is based off the metric system of units, specifically the meter. For reference, other unit abbreviations/symbols and conversions are listed:

Metric

    m: meter
    mm: millimeter
    cm: centimeter
    dm: decameter
    km: kilometer

Standard (United States)

    " (in): inch(es)
    ' (ft): foot/feet
    yd: yard
    mi: mi le

Scale Scale

Scale is referencing measurement of one thing against measurement of another thing. The relationship between the 2 things is scale. If the scale of an object is off, the object will look too big or small in relation to the surrounding objects. Keeping your objects' scales consistent will reduce disorientation and awkwardness while moving among them.

Object Manipulation

based off TAP's spec

Knowing how objects can be moved and manipulated within Active Worlds will help you design better objects that will be easier to build with. AW objects can be manipulated via keyboard and/or mouse (while it can be odd at first--and irritating after you right-click an object and accidentally move it--it can be helpful).

Keyboard
    °: degree(s) symbol
    %: percent symbol
    ½: 1/2, half, one-half; .5 ("point five")
    ¼: 1/4, fourth, one-forth; .25 ("point two-five" or "point twentyfive")

movement: one press of an arrow (left, right, up, down) or [+] (plus)/[-] (minus) key(s)
    1 movement = .5m (50cm)


rotation: one press of either the [Page Up] or [Page Down] key(s); rotation occurs around any axis

    1 rotation = 15° (1/24, one-twenty-fourth of a circle)
    3 rotations = 45° (1/8, one-eigth of a circle)
    6 rotations = 90° (¼ circle)
    12 rotations = 180° (½ circle)
    24 rotations = 360° (full circle)

[Shift]: holding down the [Shift] key with either a movement or rotation
    1 [Shift] movement = .05m (5cm, 10% of a movement)
    1 [Shift] rotation = 1.5° (10% of a rotation)

[Ctrl]+[Shift]: holding down the [Ctrl] ("Control") key and (+) the [Shift] key with either a movement or rotation
    1 [Control]+[Shift] movement = .01m (1cm, 1% of a movement)
    1 [Control]+[Shift] rotation = .1° (1/150 or .006% of a rotation)

Movement

movement[Shift][Ctrl]+[Shift]
1=10=50
1/10=1=5
1/50=1/5=1


Rotation

rotation[Shift][Ctrl]+[Shift]
1=10=50
1/10=1=15
1/150=1/10=1

Note: keyboard controls may vary depending on how you have them configured.
