Create Data Array

Group (Subgroup)

Core (Generation)

Description

This Filter creates an Attribute Array of any primitive type with any number of components along a single component dimension. For example, a scalar as (1) or a 3-vector as (3), but not a matrix as (3, 3). The array is initialized to a user define value. The primitive type of the array to create is set using an integer constant. Code listing 1 shows the values:

Primitive Type Enumeration

static const int Int8 = 0;
static const int UInt8 = 1;
static const int Int16 = 2;
static const int UInt16 = 3;
static const int Int32 = 4;
static const int UInt32 = 5;
static const int Int64 = 6;
static const int UInt64 = 7;
static const int Float = 8;
static const int Double = 9;
static const int Bool = 10;

Primitive Data Types

Type Size Range
Signed Integer 8 bit 0 to 255
Unsigned Integer 8 bit -128 to 127
Signed Integer 16 bit -32,768 to 32,767
Unsigned Integer 16 bit 0 to 65,535
Signed Integer 32 bit -2,147,483,648 to 2,147,483,647
Unsigned Integer 32 bit 0 to 4,294,967,295
Signed Integer 64 bit 9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
Unsigned Integer 64 bit 0 to 18,446,744,073,709,551,615
Float 32 bit -3.4e+38 to -1.1e-38, 0.0, 1.1e-38 to 3.4e+38 (7 digits)
Double 64 bit -1.7e+308 to -2.2e-308, 0.0, 2.2e-308 to 1.7e+308 (15 digits)
Boolean 8 bit 0 = false and any other value will be forced to 1 = true

The number of components should be at least 1. Examples of Number of Components would be 3 for an RGB Image, 1 for a gray scale image, 1 for a scalar array, 4 for a quaternions array, etc. All values of the array will be initialized to the user set value. The initialization value text box must have a user entry or the default value 0 will be used.
