A portable computing device and method for transmitting Instructor Operating Station (IOS) filtered information. A portable computing device receives IOS control and monitoring data from a simulation server, displays the IOS control and monitoring data on the portable computing device, and receives a selection by a user of at least one component of the displayed IOS control and monitoring data. The selection is performed by an interaction of the user with the displayed IOS control and monitoring data. The portable computing device determines IOS filtered information related to the selected at least one component, and transmits the IOS filtered information to a destination computing device. The determination of the IOS filtered information takes into consideration destination user access rights of a destination user. The destination device may be a simulator or a portable computing device, where the destination user performs a simulation session by interacting with the simulation server.

A method of generating a three-dimensional (3D) representation of an environment or system, wherein the method comprises the following steps, i) obtaining a plurality of sets of range-data each providing range-data to features within at least a portion of the environment or system; ii) processing the plurality of sets of range-data to fuse the data and generate a set voxels holding data to represent the 3D environment or system; ii) identifying one or more subsets of the set of voxels; and iii) applying a regularisation process to at least one of the one or more subsets to modify the data held by at least some of the voxels in the one or more subsets wherein the set of voxels provides the 3D representation of the environment.
