Detailed Description

Vector4d class.

This class creates a list like object, which can be modified using the list protocol method. But unlike lists, its length is fixed: it always contain 4 floating point values. Thus it does not support the any list methods that would affect its length. The values within can be changed, usually via the bracket operator.

# Supported list protocol methods:
color = FBColor()
len(color)
print color[0]
color[0] = 1.0    

Warning

Slicing is not supported by this object.

Constructor.

A vector can be built from any python object with supports the tuple interface and is of a lenght of 4.

Member Function Documentation

__getitem__()

float __getitem__

(

int

pIndex

)

Returns the ith component Corresponds to python: print v[1].

Parameters

pIndex
