Arrays of Directional Vectors and Points

This module provides the following dynamic array classes:

• Dir2dArray: A dynamically allocated array of Dir2d vectors.
• Dir3dArray: A dynamically allocated array of Dir3d vectors.
• Point2dArray: A dynamically allocated array of Point2d points.
• Point3dArray: A dynamically allocated array of Point3d points.

Single precision variants are also available. Simply prefix these class names with "Float" to use them.

The Dir2dArray Class (derived from s3d.util.Memory)

This class provides a dynamically allocated array of Dir2d objects.

This class has the following constant data members:

Dir2dArray.kElementClass -> The class of the elements contained in this array, in this case Dir2d.

This class has the following construction methods:

Dir2dArray (numElements)

numElements -> integer

Constructs a new array of the given number of uninitialized vectors.

Returns the new array.

Dir2dArray (array)

array -> Dir2dArray

Constructs a new array sharing the same storage with the given array.

Returns the new array.

Every instance of this class has the following member methods:

Dir2dArray:Clone ()

Returns a newly allocated copy of this array.

Dir2dArray:GetSize ()

Returns the number of Dir2d elements in this array.

Dir2dArray:GetItem (index)

index -> integer

Returns the Dir2d element at the given index of this array.

Dir2dArray:SetItem (index, item)

index -> integer

item -> Dir2d

Sets the element at the given index of this array.

Returns this modified array object as a convenience for chaining calls.

The Dir3dArray Class (derived from s3d.util.Memory)

This class provides a dynamically allocated array of Dir3d objects.

This class has the following constant data members:

Dir3dArray.kElementClass -> The class of the elements contained in this array, in this case Dir3d.

This class has the following construction methods:

Dir3dArray (numElements)

numElements -> integer

Constructs a new array of the given number of uninitialized vectors.

Returns the new array.

Dir3dArray (array)

array -> Dir3dArray

Constructs a new array sharing the same storage with the given array.

Returns the new array.

Every instance of this class has the following member methods:

Dir3dArray:Clone ()

Returns a newly allocated copy of this array.

Dir3dArray:GetSize ()

Returns the number of Dir3d elements in this array.

Dir3dArray:GetItem (index)

index -> integer

Returns the Dir3d element at the given index of this array.

Dir3dArray:SetItem (index, item)

Sets the element at the given index of this array.

Returns this modified array object as a convenience for chaining calls.

index -> integer

item -> Dir3d

The Point2dArray Class (derived from s3d.util.Memory)

This class provides a dynamically allocated array of Point2d objects.

This class has the following constant data members:

Point2dArray.kElementClass -> The class of the elements contained in this array, in this case Point2d.

This class has the following construction methods:

Point2dArray (numElements)

numElements -> integer

Constructs a new array of the given number of uninitialized points.

Returns the new array.

Point2dArray (array)

array -> Point2dArray

Constructs a new array sharing the same storage with the given array.

Returns the new array.

Every instance of this class has the following member methods:

Point2dArray:Clone ()

Returns a newly allocated copy of this array.

Point2dArray:GetSize ()

Returns the number of Point2d elements in this array.

Point2dArray:GetItem (index)

index -> integer

Returns the Point2d element at the given index of this array.

Point2dArray:SetItem (index, item)

index -> integer

item -> Point2d

Sets the element at the given index of this array.

Returns this modified array object as a convenience for chaining calls.

The Point3dArray Class (derived from s3d.util.Memory)

This class provides a dynamically allocated array of Point3d objects.

This class has the following constant data members:

Point3dArray.kElementClass -> The class of the elements contained in this array, in this case Point3d.

This class has the following construction methods:

Point3dArray (numElements)

numElements -> integer

Constructs a new array of the given number of uninitialized points.

Returns the new array.

Point3dArray (array)

array -> Point3dArray

Constructs a new array sharing the same storage with the given array.

Returns the new array.

Every instance of this class has the following member methods:

Point3dArray:Clone ()

Returns a newly allocated copy of this array.

Point3dArray:GetSize ()

Returns the number of Point3d elements in this array.

Point3dArray:GetItem (index)

index -> integer

Returns the Point3d element at the given index of this array.

Point3dArray:SetItem (index, item)

index -> integer

item -> Point3d

Sets the element at the given index of this array.

Returns this modified array object as a convenience for chaining calls.
