1. An electronic panel system for facilitating viewing and interacting with 3D computer graphics models of real objects comprising: a soft-copy display device for displaying at least one 3D model of real object; one or more processors; instructions stored in a non-transitory computer readable storage medium executable by the one or more processors that upon such execution cause the one or more processors to perform operations comprising: (a) providing a first view of at least one 3D model by a Graphical User Interface (GUI) ( 143 ) with user-controlled interactions, using one or more processors, where the GUI ( 143 ) comprises one or more interactive 3D space ( 143 a ) adapted to display one or more 3D models; (b) receiving a user input, the user input are one or more interaction commands provided using one or more input device that is integrated with the electronic panel system, where one or more interaction commands are provided for performing each user-controlled interaction in real-time; (c) identifying one or more interaction commands, using one or more processors, by user-controlled interaction unit ( 131 ); (d) in response to the identification, invoking a corresponding user-controlled interaction functionality of the user-controlled interaction unit ( 131 ), using one or more processors; (e) in response to the invoking, producing real-time rendering of user-controlled interaction response using 3D model data ( 132 a ) texture data ( 132 b ), audio ( 132 c ) and a 3D rendering engine ( 134 ), using one or more processors, by the user-controlled interaction unit ( 131 ), where the user-controlled interaction response is corresponding interactive view of the 3D model with synchronized sound or without sound as per input; (f) displaying the rendered user-controlled interaction response in one interactive 3D space ( 143 a ) of the GUI ( 143 ) through the soft-copy display device in real-time, using one or more processors, in response to the input; wherein the operations (b)-(f) are repeated to perform each user-controlled interaction; wherein at least one user-controlled interaction is performed selected from user-controlled interactions which includes extrusive and intrusive interactions, liquid and fumes flow interactions, time bound changes based interactions, environment mapping based interactions, deletion interaction, addition interaction, immersive interactions, linked movement interactions, interaction for getting un-interrupted view of internal parts using transparency-opacity effect, inter-interactions, and engineering disintegration interactions; and wherein the displayed rendered user-controlled interaction response is output result displaying effect of each performed user-controlled interaction with synchronized sound output or without sound output according to the interaction command provided in the form of input.
