PortalNode¶
-
class
PortalNode
¶ Bases:
PandaNode
A node in the scene graph that can hold a Portal Polygon, which is a rectangle. Other types of polygons are not supported for now. It also holds a PT(PandaNode) Cell that this portal is connected to

(std::string const &name)¶

explicit
PortalNode
(std::string const &name, LPoint3 pos, PN_stdfloat scale = 10.0)¶ Default constructor, just an empty node, no geo This is used to read portal from model. You can also use this from python to create an empty portal. Then you can set the vertices yourself, with
add_vertex()
.Create a default rectangle as portal. Use this to create an arbitrary portal and setup from Python
-
void
add_vertex
(LPoint3 const &vertex)¶ Adds a new vertex to the portal polygon. The vertices should be defined in a counterclockwise orientation when viewing through the portal.
-
void
clear_vertices
(void)¶ Resets the vertices of the portal to the empty list.

get_class_type
(void)¶
-
PortalMask
get_from_portal_mask
(void) const¶ Returns the current “from”
PortalMask
. In order for a portal to be detected from this object into another object, the intersection of this object’s “from” mask and the other object’s “into” mask must be nonzero.
-
PortalMask
get_into_portal_mask
(void) const¶ Returns the current “into”
PortalMask
. In order for a portal to be detected from another object into this object, the intersection of the other object’s “from” mask and this object’s “into” mask must be nonzero.
-
int
get_max_depth
(void)¶ Returns the maximum depth this portal will be visible at
-
int
get_num_vertices
(void) const¶ Returns the number of vertices in the portal polygon.
-
bool
get_portal_geom
(void) const¶ Returns the current state of the portal_geom flag. See
set_portal_geom()
.
-
bool
is_clip_plane
(void)¶ Is this portal clipping against its left-right planes
-
bool
is_open
(void)¶ Is this portal open from current camera zone
-
bool
is_visible
(void)¶ Is this portal facing the camera
-
void
set_clip_plane
(bool value)¶ this is set if the portal will clip against its left and right planes
-
void
set_from_portal_mask
(PortalMask mask)¶ Sets the “from”
PortalMask
. In order for a portal to be detected from this object into another object, the intersection of this object’s “from” mask and the other object’s “into” mask must be nonzero.
-
void
set_into_portal_mask
(PortalMask mask)¶ Sets the “into”
PortalMask
. In order for a portal to be detected from another object into this object, the intersection of the other object’s “from” mask and this object’s “into” mask must be nonzero.
-
void
set_max_depth
(int value)¶ Set the maximum depth this portal will be visible at
-
void
set_open
(bool value)¶ Python sets this based on curent camera zone
-
void
set_portal_geom
(bool flag)¶ Sets the state of the “portal geom” flag for this
PortalNode
. Normally, this is false; when this is set true, the PortalSolids in this node will test for portals with actual renderable geometry, in addition to whatever PortalSolids may be indicated by the from_portal_mask.Setting this to true causes this to test all
GeomNodes
for portals. It is an all-or-none thing; there is no way to portal with only someGeomNodes
, asGeomNodes
have no into_portal_mask.
-
void
set_portal_mask
(PortalMask mask)¶ Simultaneously sets both the “from” and “into”
PortalMask
values to the same thing.
-
void
set_visible
(bool value)¶ this is set if the portal is facing camera
