vector4

This topic is about the vector4 data type.

Value syntax

vector4 v4 = {1,1,1,0.5};

Syntax notes

Previous assignment syntax can be used only during initialization. The following code will raise an error.

vector4 v4;

v4 = {1,1,1,0.5};

After a vector4 is declared, it can be populated either by using the implemented API listed below or by assigning it the values from another vector4.

vector4 v4;

vector4 vv4 = {1,1,1,0.5};

v4 = vv4;

Description

Vector4 type is an array of four double values. It is used for properties like RGBA color.

• The default value is {0,0,0,0}.

• The vector4 type partially supports arithmetic and comparison operators.

Autocasting

Vector4 type supports automatic conversion for

• string, if in the correct input format (space separated list of four numbers); otherwise, it will raise an exception.

  vector4 v4=”1 2 3 4”; //v4={1,2,3,4};

• quaternion

  quaternion quat={1,2,3,4};

  vector4 v4=quat; //v4={1,2,3,4}

Properties
