 Based on [[http://www.ros.org/wiki/rviz/DisplayTypes/Marker|rviz Markers]], this visualization module can display 3D information in a browser-based canvas that has been built using the [[https://github.com/RobotWebTools/ros3djs|ros3djs library]].
+===== Marker Types =====
+The set of supported marker primitive types can be queried using the ''marker_prop_type(Type,_)'' predicate.
+The primitive types include arrow, cube, sphere, cylinder, line_strip, line_list, cube_list, sphere_list, points, text_view_facing, mesh_resource and triangle_list.
+Primitive markers can be created using ''marker($type('Name'),_)'', where $type must be replaced by one of the primitive types.
+In addition, KnowRob supports a set of complex marker types.
+  * **cylinder_tf(Frame0,Frame1)**: A cylinder between 2 links
+  * **link(Frame)**: A marker that takes the pose of a link
+  * **trajectory(Frame)**: A trajectory of a link
+  * **trail(Frame)**: A trail of a link (trajectory with alpha fade)
+  * **average_trajectory(Frame)**: The average over multiple trajectories
+  * **pointer(Frame0,Frame1)**: Arrow that points from Frame0 in the direction of Frame1
+  * **object(Name)**: A marker that represents an OWL individual (including children objects)
+  * **agent(Name)**: A marker that represents an OWL agent individual (including all links)
+  * **stickman(Name)**: A special human skeleton visualization, kinematic structure is spanned by the OWL individual indentified by Name
