DESCRIPTION

The Component Control packet is provided as a generic mechanism to control various components within the simulation. Because CIGI is designed to be a general-purpose interface, only the most common attributes of entities, views, and other objects are explicitly represented by attributes within specific data packets. Other attributes can be represented by components.

Components may correspond to parts or properties of entities, views and view groups, sensors, weather and environment, terrain, and even the IG itself. The type of object possessing the component is identified by the Component Class attribute. The specific instance of that object is specified by the Instance ID attribute. Depending upon the value of the Component Class attribute, the instance ID might correspond to an Entity ID, a view ID, an environmental attribute, etc. The Component ID attribute uniquely identifies the component for the instance.

Each component has zero or more discrete states, and/or up to six user-defined values. The user-defined values may either be integers or floating-point real numbers. A light, for instance, might have two discrete states (On and Off), an RGB color value represented as a 32-bit integer, and a real-value intensity level. A component representing the global lightpoint intensity value might have a real-value intensity level and no discrete states.

Regardless of how the six user-defined data fields are formatted, they will be byte-swapped as separate 32-bit values if the Host and IG use different byte ordering schemes. This ensures that all Component Control packets are byte-swapped in a consistent manner. The data should be packaged using masks and bit-wise operations so that the values are not changed when the 32-bit words are byte-swapped.

EXPORT

None by default.

Component Data 6.

This attribute represents as a float one of six 32-bit words used for user-defined component data. If this attribute is not needed by the component, this value is ignored.

Note: This attribute will be byte-swapped as a 32-bit value if the receiver and sender use different byte ordering schemes. If the attribute is used to store multiple 8- or 16-bit values, the data should be packed so that byte swapping will be performed correctly.

sub data6_short1([$newValue])

 $value = $cmp_ctl->data6_short1($newValue);

Component Data 6.

This attribute represents as a short the two most significant bytes of one of six 32-bit words used for user-defined component data. If this attribute is not needed by the component, this value is ignored.

Note: This attribute will be byte-swapped as a 32-bit value if the receiver and sender use different byte ordering schemes. If the attribute is used to store multiple 8- or 16-bit values, the data should be packed so that byte swapping will be performed correctly.

sub data6_short2([$newValue])

 $value = $cmp_ctl->data6_short2($newValue);

Component Data 6.

This attribute represents as a short the two least significant bytes of one of six 32-bit words used for user-defined component data. If this attribute is not needed by the component, this value is ignored.

Note: This attribute will be byte-swapped as a 32-bit value if the receiver and sender use different byte ordering schemes. If the attribute is used to store multiple 8- or 16-bit values, the data should be packed so that byte swapping will be performed correctly.

sub data6_byte1([$newValue])

 $value = $cmp_ctl->data6_byte1($newValue);

Component Data 6.

This attribute represents the most significant byte of one of six 32-bit words used for user-defined component data. If this attribute is not needed by the component, this value is ignored.

Note: This attribute will be byte-swapped as a 32-bit value if the receiver and sender use different byte ordering schemes. If the attribute is used to store multiple 8- or 16-bit values, the data should be packed so that byte swapping will be performed correctly.

sub data6_byte2([$newValue])

 $value = $cmp_ctl->data6_byte2($newValue);

Component Data 6.

This attribute represents the second most significant byte of one of six 32-bit words used for user-defined component data. If this attribute is not needed by the component, this value is ignored.

Note: This attribute will be byte-swapped as a 32-bit value if the receiver and sender use different byte ordering schemes. If the attribute is used to store multiple 8- or 16-bit values, the data should be packed so that byte swapping will be performed correctly.

sub data6_byte3([$newValue])

 $value = $cmp_ctl->data6_byte3($newValue);

Component Data 6.

This attribute represents the second least significant byte of one of six 32-bit words used for user-defined component data. If this attribute is not needed by the component, this value is ignored.

Note: This attribute will be byte-swapped as a 32-bit value if the receiver and sender use different byte ordering schemes. If the attribute is used to store multiple 8- or 16-bit values, the data should be packed so that byte swapping will be performed correctly.

sub data6_byte4([$newValue])

 $value = $cmp_ctl->data6_byte4($newValue);

Component Data 6.

This attribute represents the least significant byte of one of six 32-bit words used for user-defined component data. If this attribute is not needed by the component, this value is ignored.

Note: This attribute will be byte-swapped as a 32-bit value if the receiver and sender use different byte ordering schemes. If the attribute is used to store multiple 8- or 16-bit values, the data should be packed so that byte swapping will be performed correctly.

sub pack()

 $value = $cmp_ctl->pack();

Returns the packed data packet.

sub unpack()

 $value = $cmp_ctl->unpack();

Unpacks the packed data packet.

sub byte_swap()

 $obj_name->byte_swap();

Byte swaps the packed data packet.
