The simulation data storage unit 4 is provided in common to a plurality of drawing data creation devices 2 and is a storage device such as a storage server connected to the network 3, for example. The network 3 connects between the user device 1 and each of the plurality of drawing data creation devices 2, and connects between each of the plurality of drawing data creation devices 2 and the simulation data storage unit 4. Although FIG. 1 shows only one drawing data creation device 2, in practice, a plurality of drawing data creation devices 2 are provided as shown in FIG.

  The user device 1 is an information processing device used by a user such as a researcher, for example. The user device 1 allocates drawing data creation processing to each drawing data creation device 2 and displays the drawing data created by each drawing data creation device 2. To do. The drawing data creation device 2 is a processing device that executes drawing data creation processing allocated to the device itself by the user device 1 to create drawing data, and transmits the created drawing data to the user device 1 through the network 3. . The drawing data creation device 2 executes drawing data creation processing such as isosurface creation, volume rendering, and surface rendering. In the present embodiment, it is assumed that which drawing data creation device 2 executes which drawing data creation processing is determined in advance.

  The user device 1 includes a drawing instruction unit 11, a display unit 12, and an input unit 13. The drawing instruction unit 11 transmits the drawing command, the data type parameter corresponding to the extracting command, and the drawing parameter corresponding to the drawing command to each drawing data creation device 2 through the network 3. Thus, each of the drawing data creation devices 2 has a function as processing allocation means for assigning drawing data creation processing.

  The extraction command is a command related to creation of drawing data. The extraction command is a command for instructing the illustrated command execution unit 21 included in the drawing data creation device 2 to extract simulation data from the simulation data storage unit 4. The simulation data storage unit 4 stores simulation data used for creating drawing data. The simulation data is data from which each drawing data creation device 2 creates drawing data, for example, a simulation related to a living body, nanotechnology, environment, etc., which is executed in advance by a predetermined simulation device (not shown). It is the data which shows the execution result of.

  The illustration command is a command related to creation of drawing data. The illustrated command is a command for instructing the illustrated command execution unit 21 included in the drawing data generating device 2 to generate drawing data.

The simulation data in this embodiment is assumed to include a plurality of time information and a plurality of data types.

  The graphical parameter is a parameter related to creation of drawing data. The graphical parameters include an input / output transfer function related to creation of drawing data and viewpoint information. The transfer function of the input / output system related to the creation of drawing data defines what attribute drawing data is created. When the drawing data creation process executed by the drawing data creation device 2 is volume rendering, the transfer function is, for example, a histogram indicating the luminance distribution of the drawing data, a color map of the drawing data, and the transparency of the drawing data. In addition, when the drawing data creation process executed by the drawing data creation device 2 is isosurface creation, the transfer function is, for example, a luminance threshold value (isosurface threshold value) or an isovalue as a reference for isosurface creation. Surface transparency, etc. Note that the greater the isosurface threshold, the smaller the isosurface region created based on the threshold. The viewpoint information is information indicating from which direction the drawing data is to be created.

  The drawing instruction unit 11 transmits, for each drawing data creation device 2, a data type parameter including time information different from the time information included in the data type parameter transmitted to another drawing data creation device. As a result, the drawing instruction unit 11 causes each drawing data creation device 2 to perform drawing data creation processing corresponding to the time information included in the data type parameter transmitted to the own drawing data creation device 2.

  For example, the drawing instruction unit 11 transmits a data type parameter including time information of time t1 and a data type of pressure to the first drawing data creation device 2 together with an extraction command.

The drawing data storage unit is provided in the display unit 2. For example, the display unit 12 continuously displays the isosurfaces corresponding to the times t1, t2, and t3 according to the order of the times. In this way, by sequentially displaying each drawing data according to the order of time information corresponding to each drawing data, the drawing data can be displayed as a moving image.

  When drawing data corresponding to a time existing between any two arbitrary times is not stored in the drawing data storage unit, the display unit 12 uses the drawing data corresponding to each of the two times. Then, interpolation processing may be performed to create and display drawing data corresponding to a time between two times.

  Apart from the embodiment described above, the drawing instruction unit 11 may perform the following processing.

  That is, for each drawing data creation device 2, the drawing instruction unit 11 includes a data type parameter including the same time information (for example, t1) and a transfer function included in the illustrated parameter transmitted to another drawing data creation device.

Drawing data corresponding to the transfer function included in the parameter is generated. And the display part 12 displays the drawing data corresponding to the selected transfer function among each drawing data corresponding to the same time information received from each drawing data creation apparatus 2.

In response to this, the input unit 13 inputs operation information according to the pressing operation of the pause button 104, and the display unit 12 pauses the display of the moving image displayed on the display screen 100.

  Next, the user sweeps the mouse in the direction indicated by the arrow on the display screen 100 of FIG. 8 (# 82). In response to this, the drawing instruction unit 11 of the user device 1 updates the original viewpoint information to the viewpoint information corresponding to the direction indicated by the arrow.

  In this state, the user presses down the frame return button 101, for example (# 83). In response to this, the drawing instruction unit 11 transmits the updated viewpoint information to the drawing data creation apparatus 2 that is responsible for creating the drawing data corresponding to the time before time t9, and uses the updated viewpoint information as the updated viewpoint information. Create the corresponding drawing data. Here, the time t9 is a time before the time t10 when the pause button 104 is pressed because the frame return button 101 is pressed, and for example, the time when the frame return button 101 is pressed is the time t9. It is the time subtracted from.

  After the above processing, the display unit 12 receives drawing data corresponding to the updated viewpoint information from the drawing data creation device 2, and displays the received drawing data in reverse order with respect to time information corresponding to the drawing data. To reverse the video.
