Calculates the minimum and maximum vertices of all Geoms at these NodePath's bottom nodes and below This is a tight bounding box; it will generally be tighter than the bounding volume returned by get_bounds() (but it is more expensive to compute).
The return value is true if any points are within the bounding volume, or false if none are.

CollideMask NodePathCollection::get_collide_mask | ( | ) | const |
Returns the union of all of the into_collide_masks for nodes at this level and below.
This is the same thing as node()->get_net_collide_mask().
If you want to return what the into_collide_mask of this node itself is, without regard to its children, use node()->get_into_collide_mask().

void NodePathCollection::set_attrib | ( | const RenderAttrib * | attrib, |

Applies the indicated RenderAttrib to all NodePaths in the collection.
An effort is made to apply the attrib to many NodePaths as quickly as possible; redundant RenderState compositions are not duplicated.

) |
Recursively applies the indicated CollideMask to the into_collide_masks for all nodes at this level and below.
The default is to change all bits, but if bits_to_change is not all bits on, then only the bits that are set in bits_to_change are modified, allowing this call to change only a subset of the bits in the subgraph.

void NodePathCollection::set_texture | ( | Texture * | tex, |
int | priority = 0 |
||
) |
Adds the indicated texture to the list of textures that will be rendered on the default texture stage.
This is the deprecated single-texture variant of this method; it is now superceded by set_texture() that accepts a stage and texture. However, this method may be used in the presence of multitexture if you just want to adjust the default stage.
Definition at line 401 of file nodePathCollection.cxx.
void NodePathCollection::set_texture | ( | TextureStage * | stage, |
Texture * | tex, | ||
int | priority = 0 |
||
) |
Adds the indicated texture to the list of textures that will be rendered on the indicated multitexture stage.
If there are multiple texture stages specified (possibly on multiple different nodes at different levels), they will all be applied to geometry together, according to the stage specification set up in the TextureStage object.
Definition at line 414 of file nodePathCollection.cxx.
void NodePathCollection::set_texture_off | ( | int | priority = 0 | ) |
Sets the geometry at this level and below to render using no texture, on any stage.
This is different from not specifying a texture; rather, this specifically contradicts set_texture() at a higher node level (or, with a priority, overrides a set_texture() at a lower level).
Definition at line 441 of file nodePathCollection.cxx.
void NodePathCollection::set_texture_off | ( | TextureStage * | stage, |
