  18. 18. Software for 3D Interactive Visualization and Animation 5/22/2018 18
  19. 19. Problem 5/22/2018 19  Usually technicians at various plants have and operate using two-dimensional plans and instructions (texts, images and video) of machines.  But actually they have to operate with real three-dimensional equipment and its details  The need of 3D visualization
  20. 20. Solution 5/22/2018 20  Development of software for 3D interactive visualization of the specialized equipment using nVidia 3D Vision ready stereoscopic computer system, 3D projector and 3D shutter glasses.  A specific software project is being performed for a Hydro Multi-E Pressure Booster System from Grundfos with Three Identical Grundfos Pumps of CR(I)E type.
  21. 21. Technicians’ Responsibilities and Mechanical Tasks in Commissioning 5/22/2018 21  To check and test of equipment  To perform constructional and technical completion.  To disassemble the equipment in correct order and manner with the correct instruments in order to prepare the parts for commissioning.  To assemble the equipment in correct order and manner with the correct instruments in order to prepare the equipment for operation.
  22. 22. The Project 5/22/2018 22  The aim is to create software application for VR interactive visualization and animation of assembly and disassembly for commissioning of Hydro Multi-E pressure booster system from Grundfos. The main tasks of this VR application are:  To train technicians that has to perform these operations.  To support the technicians during the disassembly and assembly processes guiding them to choose the correct part of the equipment, to be removed/ to be placed according to its categorization.
  23. 23. Potentialities 5/22/2018 23  3D stereoscopic visualization on nVidia 3D Vision ready computer system  Ability a technician to examine the 3D model of the equipment and its parts separately  Ability a technician to choose a particular part of the equipment from a list of all parts and perform the operations mentioned in the previous point.  Ability a technician to read the technical information for a particular part of the equipment
  24. 24. Potentialities 5/22/2018 24  Ability a technician to examine the assembly and disassembly process of the equipment in VR mode.  Ability a technician to step through the animated sections, to examine the particular state of the assembly or disassembly process and decide to go further or go back in some steps.
  25. 25. Development process  Stereo visualization  Model loading library  Image loading library  GUI - AntTweakBar 25
  26. 26. Software Functionalities 5/22/2018 26  Stereoscopic 3D view of all parts of the equipment in passive and active (animation) mode.  Availability for visualization of each part of the equipment.  Technicians can examine the selected part from each side.  Technician can move, zoom in and zoom out the view.  Availability for fast access to specialized technical information selected for each part of the equipment.
  27. 27. Benefits 5/22/2018 28  Technicians will be ready for disassembling and assembling of the specialized equipment.  Technicians have three-dimensional and interactive software with detailed graphical (visual) instructions for disassembling and assembling of the equipment.  Technicians have a complete package of information about the equipment assessable through very friendly graphical user interface of the software.  Technicians have very fast access to the complete package of specifications, instructions and safety techniques about all parts of the equipment and the specialized instrument.  Technicians have a software module for light spare parts management.
