Detailed Description

Vector3d 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 3 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 & Destructor Documentation

FBVector3d() [1/4]

FBVector3d

(

)

Constructor.

Default constructor, all 3 values within are set to 0.0.

FBVector3d

pVector3d

)

Constructor.

Copy constructor. Copy values from another instance.

FBVector3d() [3/4]

FBVector3d	(	float	pX,
		float	pY,
		float	pZ
	)

Constructor.

Explicitely construct a vector by specifying its values.

FBVector3d() [4/4]

)

Constructor.

A vector can be built from any python object with supports the tuple interface and is of a lenght of 3.

Member Function Documentation

__getitem__()

float __getitem__

(

int

pIndex

)

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

Parameters

pIndex

Index of the components to get (0 to 2)

Returns

Color component value.

__len__()

int __len__

(

)

Returns the number of elements.

Corresponds to python: len(object)

__setitem__()

__setitem__	(	int	pIndex,
		float	pComponentValue
	)

Sets the ith components Corresponds to python: v[1] = 0.5.

Parameters

pIndex	Index of the components to set (0 to 2)
pComponentValue	Value of component to set

operator+()

FBVector3d operator+

(

FBVector3d

pVector

)

Parameters

pVector

Vector to add to source.

Returns

The substraction of both vectors.
