class Frustum(Node) |
| |
Holder for frustum specification for intersection tests
Note:
the Frustum can include an arbitrary number of
clipping planes, though the most common usage
is to define 6 clipping planes from the OpenGL
model-view matrices.

- Method resolution order:

Class methods defined here:
- fromViewingMatrix(cls, matrix=None, normalize=1) from type
- Extract and calculate frustum clipping planes from OpenGL
The default initializer allows you to create
Frustum objects with arbitrary clipping planes,
while this alternate initializer provides
automatic clipping-plane extraction from the
model-view matrix.
matrix -- the combined model-view matrix
normalize -- whether to normalize the plane equations
to allow for sphere bounding-volumes and use of
distance equations for LOD-style operations.
- normalize(cls, frustum) from type
- Normalize clipping plane equations
Properties defined here:
- normalized
- field SFBool normalized 1
- normalized getter = fget(self, client) from SFBool
- Get the client's value for this property
if notify is true send a notification event.
- normalized setter = fset(self, client, value, notify=1) from SFBool
- Set the client's value for this property
if notify is true send a notification event.
- normalized deleter = fdel(self, client, notify=1) from SFBool
- Delete the client's value for this property
if notify is true send a notification event.
- planes
- exposedField MFVec4f planes []
- planes getter = fget(self, client) from MFVec4f
- Get the client's value for this property
if notify is true send a notification event.
- planes setter = fset(self, client, value, notify=1) from MFVec4f
- Set the client's value for this property
if notify is true send a notification event.
- planes deleter = fdel(self, client, notify=1) from MFVec4f
- Delete the client's value for this property
if notify is true send a notification event.

Methods inherited from Node:
- __init__(self, **namedarguments)
- Initialise the node with appropriate named args
All properties/attributes must be specified with
named arguments, and the property/attribute must
exist within the Node's class/prototype.
This will raise AttributeError/ValueError/TypeError
if the values or the property names are inappropriate.
Note that all Node objects have the attribute/property
exposedField SFString DEF ""
defined. You may therefore specify a DEF name by
passing it as a named argument.
- __repr__(self)
- Get a code-like representation of the Node
Basically every attribute except for sub-nodes values
are returned as a full representation.
- __str__(self)
- Get a friendly representation of the Node
- copy(self, copier=None)
- Copy this node for copier
- toString(self, **namedargs)
- Generate a VRML 97-syntax string representing this Prototype
**namedargs -- key:value
passed arguments for the linearisation object
see lineariser4.Lineariser
Properties inherited from Node:
- DEF
- exposedField SFString DEF
- DEF getter = fget(self, client) from SFString
- Get the client's value for this property
if notify is true send a notification event.
- DEF setter = fset(self, client, value, notify=1) from SFString
- Set the client's value for this property
if notify is true send a notification event.
- DEF deleter = fdel(self, client, notify=1) from SFString
- Delete the client's value for this property
if notify is true send a notification event.
- rootSceneGraph
- exposedField WeakSFNode root NULL
- rootSceneGraph getter = fget(self, client) from WeakSFNode
- Get the client's value for this property
if notify is true send a notification event.
- rootSceneGraph setter = fset(self, client, value, notify=1) from WeakSFNode
- Set the client's value for this property
notify -- if true send a notification event
The SFNode tries to update the value's root
attribute to point to the root of the client
*iff* the value doesn't currently point at
a valid root. (That is, it only updates root
if there is no current root). This is done
without sending notify events.
- rootSceneGraph deleter = fdel(self, client, notify=1) from WeakSFNode
- Delete the client's value for this property
if notify is true send a notification event.
