A "smart" geometry loading class that caches previous geometries, and does not re-load or re-initialize existing collision detection data structures if the item has already been loaded.
Note: the standard Load function will load a file if it hasn't been loaded before, or if it has, it will copy the existing data structures from a prior loaded value. If the collision data structure of the prior geometry haven't been created, they will be created and copied to the new geometry.
Note: if you wish to transform a geometry by a non-rigid transformation, you will need to call RemoveFromCache. Otherwise, all subsequent Load calls will load the transformed geometry. Here, the TransformGeometry method of this class does this for you.
Note: geometries are not shared, but rather cached-and-copied. Appearances on the other hand are by default shared. To make an object have its own custom appearance, call SetUniqueAppearance().
Note: the Load / LoadNoCache functions can also accept strings of the form "ros://[ROS_TOPIC]" or "ros:PointCloud2//[ROS_TOPIC]" to load dynamic point clouds from ROS topics. Only PointCloud2 messages are accepted for now.
| bool ManagedGeometry::DynamicGeometryUpdate | ( | ) |
Updates dynamic geometry, if an update is available. If no update, returns false
| bool ManagedGeometry::IsAppearanceShared | ( | ) | const |
Returns true if there are multiple objects sharing the appearance data. If it is shared, then changing one appearance affects multiple objects.
|
static |
Returns NULL if the file hasn't been cached. Otherwise, returns a prior instance of the geometry.
| void ManagedGeometry::SetUnique | ( | ) |
Removes this geometry from the cache and separates its appearance data from all other instances of this object.
| void ManagedGeometry::SetUniqueAppearance | ( | ) |
Makes this item have its own appearance data separate from all other instances of this object.
| void ManagedGeometry::TransformGeometry | ( | const Math3D::Matrix4 & | xform | ) |
Transforms the geometry (requires removing from cache, and re-initializing collision data).
