## Additional Inherited Members
Public Attributes inherited from Group
DynamicArray< CompatabilityListItem > | _compatList
| Used for GL Studio 2.1 compatibility only.

## Detailed Description

The GlsLodGroup allows users to set different levels of detail (LOD) for its contents based on how far the group is from the camera.
The GlsLodGroup renders a single child, and chooses which child to render based on the distance from the current camera and the values set on each LOD position in the editor. LODs are only used with perspective cameras.

## Constructor & Destructor Documentation

## ◆ GlsLodGroup() [1/2]

GlsLodGroup | ( | bool | generateInstance = `false` | ) |
| explicit

Create a new GlsLodGroup.

Parameters

  generateInstance | Whether or not to generate an instance name for this inputdevice

## ◆ GlsLodGroup() [2/2]

GlsLodGroup | ( | const GlsLodGroup & | that,
|  | const bool | generateNames
| ) |  |

Copy constructor

Parameters

  that | The object to copy from.
  generateNames | Whether or not to generate an instance name.

## Member Function Documentation

## ◆ CreateInstance()

static DisplayObject * CreateInstance | ( |  | ) |
| static

Returns
  A pointer to a new GlsLodGroup object.

## ◆ Draw()

void Draw | ( |  | ) |
| virtual

Draws this object on the current display frame (_parent member). Pure virtual method

Reimplemented from Group.

## ◆ GetLodPosition()

virtual float GetLodPosition | ( | int | index | ) |
| virtual

Returns
  The normalized (0-100) position of the desired LOD index.

Parameters

  index | The LOD index whose position is to be returned.

## ◆ GroupDebugCommand()

static void GroupDebugCommand | ( | const char * | cmd,
|  | const char * | arg
| ) |  |
| static

Unused, kept for backward compatibility.

Parameters

  cmd |
  arg |

## ◆ InsertObject()

void InsertObject | ( | DisplayObject * | obj,
|  | bool | reparent = `true`,
|  | bool | recalculateBoundingbox = `true`,
|  | int | loc = `-1`
| ) |  |
| virtual

Adds the specified object into the group, at the end of the list

Parameters

  obj | A pointer to the object to add
  reparent | Whether or not the object parent should be set to this group
  recalculateBoundingbox | Whether or not to recalculate the bounding box
  loc | Where to insert it (defaults to -1 which means at the end of the list)

Reimplemented from Group.

## ◆ NumLods()

virtual int NumLods | ( |  | ) |
| virtual

Returns
  The number of LOD positions defined in this object.

## ◆ PreDraw()

void PreDraw | ( | const OpenGLMatrices & | current,

| ) |  |
| virtual

Traverses the hierarchy calculating the _modelMatrix, _projMatrix, _viewMatrix as needed.

Parameters

  current | Current matrices inherited from parent
  culler | Object that possibly marks this object for culling

Reimplemented from Group.

## ◆ SetAvailableAttributes()

void SetAvailableAttributes | ( | unsigned int | value | ) |
| virtual

Specifies which attributes are available for the object. Currently the available attributes cannot be changed after they have been set. (Only the first call has an effect.)

Parameters

  value | A bitfield specifying which types of attributes to make available.

See also
  AvailableAttributesEnum

Reimplemented from Group.

## ◆ SetFromGloData()

void SetFromGloData | ( | GlsGloFileAttribute & | data | ) |
| protected virtual

Set a single attribute from the GLO file.

Parameters

Reimplemented from DisplayObject.

## ◆ SetValue()

void SetValue | ( | int | spec,
|  | va_list & | args
| ) |  |
| protected virtual

Sets an attribute of this object using variable arguments

Parameters

  spec | A GLS_Initializer tag
  args | A variable argument list

Reimplemented from DisplayObject.
