Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine such as a pachinko gaming machine, and more particularly to a gaming machine having a variable display function for variably displaying predetermined identification information.

[0002]

2. Description of the Related Art In gaming machines such as pachinko gaming machines,
Liquid crystal display device (hereinafter, LCD: Liquid Crys
On a display device such as a tal display), a plurality of types of identification information (hereinafter referred to as display symbols) prepared in advance are displayed in a variable manner, and it is determined whether or not a predetermined game value is given based on the display result. There are many floating display games that enhance the enjoyment of the game.

Some floating display games are played by using the above-mentioned display device mainly as an image display device (hereinafter, a special figure game). In the special figure game, the display symbol is variably displayed with the detection of the game ball passing through the predetermined area, and the derived display mode when the variable display result of the display symbol is derived and displayed is the specific display mode. It is a game of "big hit". When the "big hit" occurs in the special drawing game, a special electric prized object called a special winning opening is operated to open the special winning opening door. As a result, the player is continuously provided with a state in which winning of the game ball is extremely easy for a certain period of time.

The following is a big hit in the special drawing game,
When the special winning opening door is opened, it is extremely easy for the player to win a game ball, which is called a specific game state. In order to be in the specific game state, usually, the derivation display mode of the display symbol displayed on the special symbol display device becomes a predetermined specific display mode (generally,
The condition is that the display symbols displayed on the plurality of variable display portions of the special symbol display device are the same symbol).

As described above, in the special figure game, the player pays the greatest attention to whether or not the stop symbol mode becomes the "big hit" as the specific display mode. For this reason, until the stop symbol mode that can be determined whether or not to be a "big hit" is determined, various effect displays are performed to enhance the enjoyment of the game.

Further, not only the pachinko gaming machine but also a gaming machine such as a slot machine equipped with an image display device such as an LCD can acquire a "bonus game" equivalent to a "big hit" in the pachinko gaming machine. In the process of flag establishment, some LCDs use the LCD to perform the same effect display as a pachinko gaming machine. In a gaming machine that performs such effect display, in order to maintain the expectation that the flag of “big hit” or “bonus game” will be established during effect display, effect display with a higher visual effect is required. Has been done.

The oscillator circuit 21 includes a CPU 23 and a GTE 26.
And VDP27, and the reset circuit 22 outputs a reset signal for resetting the CPU 23, the GTE 26, and the VDP 27. When the display control command data is input from the game control unit 11, the CPU 23 reads the control data for display control from the ROM 24 while using the RAM 25 as a work area. Further, the CPU 23 outputs a control signal to the VDP 27 based on the read control data. The ROM 24 is a semiconductor memory that stores various control programs used by the CPU 23.
The AM 25 is a semiconductor memory used as a work area by the CPU 23.

The GTE 26 operates as a coprocessor of the CPU 23, and executes coordinate conversion and light source calculation, which are indispensable for three-dimensional graphics, such as fixed-point matrix and vector operations at high speed by a parallel processing mechanism. Specifically, the GTE 26 is an address on the display area of the processing target image based on the coordinate data of each vertex, the movement amount data and the rotation amount data in the two-dimensional or three-dimensional plane of the image data supplied from the CPU 23. Is calculated and the calculated address data is returned to the CPU 23 again, and the brightness of the image according to the distance and angle from the virtually set light source is calculated. Further, the calculation result can be directly embedded in a drawing command to the VDP 27 described later.

The VDP 27 has a display device control function for displaying an image and a high speed polygon drawing function for the frame buffer 30, and operates according to a polygon drawing command from the CPU 23. Further, it has a two-dimensional address space independent of the CPU 23, and the frame buffer 30 is mapped therein. Character ROM 28
Is character image data that is frequently used among the images displayed on the special symbol display device 4, specifically, a person,
It is for storing animals, characters, figures, symbols, etc. in advance. It also stores shape models of various objects, texture images, and color palette data.

In particular, in this embodiment, the character ROM 28 stores the three-dimensional object to be displayed.
As shown in FIG. 5A, a three-dimensional model MO defined by a combination of a plurality of polygons is stored. As shown in FIG. 5B, each three-dimensional model MO has a sphere centering on the center number CE of the three-dimensional model and enclosing (contacting) the three-dimensional model (inscribed sphere). The radius R of SP is set.

In the character ROM 28, the number of each three-dimensional model, the center position, and the radius R of the inscribed sphere SP are stored in association with each other, as shown in FIG. .

Unlike the three-dimensional model MO that constitutes the background, a special symbol (identification information) S that influences the progress of the game.
I is composed of a two-dimensional image. In the special symbol SI, as shown in FIG. 6, an inscribed circle CI is set instead of the inscribed sphere.

Here, as shown in FIG. 4, the VDP 27 has a frame buffer 30, a CPU interface 31, an attribute table 32, a sprite arithmetic unit 33, and CGROM interfaces 34, 35.
A color bus controller 36, a palette table 37, a DAC conversion table 38, a D / A converter 39, and a synchronization timing controller 40.

The frame buffer 30 is an image memory managed by the VDP 27, and is for expanding the image data generated by the VDP 27. Further, the dual port configuration is adopted so that the drawing access can be executed even for the area being displayed. The LCD drive circuit 29 converts the image data input from the VDP 27 into
It is converted into a video signal composed of a color signal and a synchronization signal, and is output to the special symbol display device 4.

The CPU interface 31 is the CPU 2
It is for fetching the drawing command from 3. The attribute table 32 stores attributes for each image data to be displayed, for example, a function that defines the size, the moving direction, and the moving amount, and attributes such as the priority set for each sprite data.

The color bus controller 36 is for inputting / outputting a color code or a palette code. The palette table 37 determines the color of the image data based on the palette code set by the color bus controller 36. The DAC conversion table 38 is for applying gamma correction or the like so that the color determined by the palette table 37 is correctly displayed in accordance with the display characteristics of the LCD used in the special symbol display device 4. The D / A converter 39 converts the digital signal corrected by the DAC conversion table 38 into an analog signal. The synchronization timing controller 40 outputs a synchronization signal (horizontal synchronization signal, vertical synchronization signal, clock signal) to be supplied to the LCD drive circuit 29 based on the clock signal from the oscillation circuit 21 and the reset signal from the reset circuit 22.

The VDP 27 has the above-described configuration and is used by the CPU 2
Based on an instruction from 3, the display target object OB formed of polygons is arranged in a virtual three-dimensional (XYZ) space as shown in FIG.
An image obtained by projecting on the image is obtained by arithmetic processing, and this image is displayed on the special symbol display device (image variable display device) 4 by controlling the LCD drive circuit 29.

In the normal three-dimensional image processing, the VDP 27
Processes the polygons that make up the three-dimensional model for all three-dimensional objects in the virtual three-dimensional space, and then sorts the polygons by Z value (Z-axis direction (depth direction) coordinate value). Thus, the so-called hidden surface processing is performed in which the foremost polygon is obtained and displayed, and the other polygons are not displayed. That is, polygon processing is also performed on a three-dimensional object that is hidden by other objects and is not displayed.

On the other hand, in this embodiment, as schematically shown in FIG. 8, for an image hidden by a certain image (two-dimensional or three-dimensional) arranged in a three-dimensional space, Polygon processing (drawing processing) is not performed. By performing such processing, it is possible to suppress the number of polygons to be processed and speed up the processing as a whole.

It is to be noted that, as for the three-dimensional object determined to be the display target, processing of polygons constituting the three-dimensional model is performed, and further hidden surface processing is performed to obtain a final display image as in the conventional case. Is.

Next, the operation (action) of this embodiment will be described.

First, the outline of the game flow in the pachinko gaming machine of this embodiment will be described. By rotating the handle provided at the lower right position of the pachinko gaming machine 1, a game ball is launched into the game area. In the game control unit 11, the presence or absence of an input such as a special symbol start switch in the input / output unit 12 is monitored, and the game ball has a special symbol start port 6
When winning the prize, the winning of the game ball is detected by the special symbol start switch. Further, when the winning of the game ball is detected at the special symbol starting port 6, the number of winning game balls and the random number lottery value at the time of winning are stored in the special symbol determining bank. Then, the special symbol game is started on the special symbol display device 4 based on the stored data.

FIG. 9 is a flow chart showing the main processing executed by the CPU in the game control section 11. When the power to the gaming machine is turned on, in the main process, C
The PU performs necessary initialization processing.

In the initial setting process, the CPU first
Set the interrupt mode to the interrupt disabled state (step S1
01: Hereinafter, simply referred to as S101), subsequently, the interrupt mode is set to the interrupt mode 2 (S102), and the stack pointer designated address is set to the stack pointer (S103). Next, after setting the built-in device registers, that is, initialization (S104), and after setting the built-in devices, CTC (counter / timer) and PIO (parallel input / output port), that is, initialization (S10).
5) Set the RAM in the accessible state (S10)
6).

The CPU in the game control unit 11 used in this embodiment has a maskable interrupt (I
The following three types of modes are prepared as NT) modes. When a maskable interrupt occurs, the CPU in the game control unit 11 automatically sets the interrupt disabled state and saves the contents of the program counter in the stack.

Interrupt mode 0: The built-in device that has made an interrupt request sends an RST instruction (1 byte) or a CALL instruction (3 bytes) to the internal data bus of the CPU.
Therefore, the CPU executes the instruction at the address corresponding to the RST instruction or the address specified by the CALL instruction.
At reset, the CPU automatically enters interrupt mode 0, so if you want to set interrupt mode 1 or interrupt mode 2, you need to perform processing to set interrupt mode 1 or interrupt mode 2 in the initialization process. There is.

Interrupt mode 1: When an interrupt is accepted, the mode is always to jump to the address 0038 (h).

Interrupt mode 2: A mode in which an address composed of a value (1 byte) of a specific register (I register) of the CPU and an interrupt vector (1 byte: least significant bit 0) output by an internal device indicates an interrupt address. Is.
That is, the interrupt address is an address indicated by 2 bytes in which the upper address is the value of the specific register and the lower address is the interrupt vector. Therefore, interrupt processing can be provided at arbitrary even addresses, although they are scattered. Each built-in device has a function of sending an interrupt vector when making an interrupt request.

Therefore, when the interrupt mode 2 is set,
It becomes possible to easily process an interrupt request from each built-in device, and it is possible to provide an interrupt process at an arbitrary position in the program. Furthermore, unlike the interrupt mode 1, it is easy to prepare each interrupt process for each interrupt generation factor. Because of such features, in the present embodiment, the CPU in the game control unit 11 sets the interrupt mode 2 in S102 of the initial setting process.

Next, it is determined whether or not the clear switch provided in the gaming machine is on (S10).
7). Here, if the clear switch is on (S107; YES), the process proceeds to S110, which will be described later.
On the other hand, if the clear switch is not turned on (S1
07; NO), and it is determined whether or not data protection processing of the backup RAM area, such as addition of parity data, is performed when the power is turned off (S108). In this embodiment, in the event of an unexpected power failure, the backup RA
Processing for protecting the data in the M area is performed. Therefore, it is determined that there is a backup when the data protection process has been performed. Then, when it is determined that there is no backup, the CPU executes the initialization process of S110 and later described later.

When it is determined that there is a backup in the determination processing of S108, the CPU sets the internal state of the game control unit 11 and the control states of the respective control units such as the display control unit 13 and the payout control unit 16 to the states before power-off. Perform recovery processing to return (S1
09). Then, the saved value of the program counter stored in the backup RAM area is reset to the program counter and restored to that address.

FIG. 10 is a CPU in the game control unit 11.
5 is a flowchart showing a power-off process executed by the. In the power-off process, when it is detected that the voltage has dropped below the predetermined voltage value, the RAM checksum operation is performed (S203) after saving the register (S201) and the stack pointer (S202). Next, the RAM is set to the access prohibited state (S204) and the output port is cleared (S205). When it is ready to be inoperable, it waits in this state.

Returning to FIG. 9, if it is determined that there is no backup in the determination processing of S108, the CPU executes the initialization processing. That is, first, while performing a RAM clear process (S110), a predetermined work area (for example, a random symbol for normal symbol determination, a normal symbol determination buffer, a special symbol left middle right symbol buffer, a payout command storage pointer, etc.)
An initial value setting process for setting an initial value to is also performed. next,
Processing for initializing sub boards such as the pattern control board 13, the sound control board 14, the lamp control board 15, the payout control board 16 is executed (S111).

As the process of initializing the sub-board, for example, a process of sending an initial setting command is performed. As the initial setting command, when the payout is possible, the payout control unit 1
6, a payable state designation command to be output, or a payout stop state designation command to be output to the payout control unit 16 when the payout is impossible, and the like. The undeliverable state includes, for example, a state in which a ball out switch or a full tank switch (both not shown) is turned on.

That is, the CPU sends a payout stop state designation command to the payout control unit 16 if the out-of-ball switch or the full tank switch is turned on, and otherwise sends a payable state designation command. The payable state designation command or the payout stop state designation command is S1.
It may be output also in the game state recovery processing of 09.

Then, the CTC register provided in the CPU is set so that the timer interrupt occurs periodically (every 2 milliseconds) (S112). That is, a value corresponding to 2 ms as an initial value is set in a predetermined register (time constant register). After that, after setting the interrupt disabled state (S113), the display symbol random number updating process for updating the count value of the counter for generating the display random number is executed (S114), and the initial value determining random number updating process is executed. (S115), the process of setting the interrupt enabled state is performed (S116). Hereinafter, S113 to S1
The processing of 16 is repeatedly executed.

The interrupt disabled state is realized by issuing an interrupt disabled instruction, setting the interrupt disable register to disabled, and setting a mask register. The interrupt enabled state issues an interrupt enabled instruction. Or
It is realized by setting the register for interrupt prohibition to enable or resetting the mask register. Also,
The initial value determination random number is a random number for determining the initial value of the big hit determination random number.

Display symbol random number updating process in S114,
The random number updating process for initial value determination in S115 and S115 is executed in the interrupt disabled state. Therefore, when the numerical value updating process is being executed, a maskable interrupt such as a timer interrupt is not applied, and the numerical value updating process is executed without being interrupted by the interrupt process.

In this embodiment, the built-in CTC of the CPU is set to repeatedly generate a timer interrupt.
Then, the repetition cycle is set to 2 milliseconds. Then, when a timer interrupt occurs, timer interrupt processing as described later is executed.

FIG. 11 is a CPU in the game control unit 11.
5 is a flowchart showing a timer interrupt process executed by the. In the timer interrupt process, the CPU first executes a register save process (S301), and then S3 described below.
Each game control process of 02 to S314 is sequentially executed. When these game control processes are completed, register restoration processing is performed (S315), and the interrupt enabled state is set (S31).
6).

In the game control process, the CPU inputs the states of switches such as a gate switch, a starting opening switch, a count switch, and a winning opening switch through a switch circuit (not shown) in the input / output unit 12, Those states are determined (switch process: S302). Next, various abnormality diagnosis processing is performed by the self-diagnosis function provided inside the pachinko gaming machine 1, and an alarm is issued if necessary according to the result (error processing: S3
03).

Next, a random number updating process for updating each counter showing each judgment random number such as a big hit judgment random number used for game control is carried out (S304). The CPU further performs an initial value determination random number updating process (S305) and a display symbol random number updating process (S306). Note that S305 and S3
The content of the processing of 06 is the same as the processing of S115 and S114 described above.

Further, the CPU performs a special symbol process process which will be described in detail later (S307). In this special symbol process process, as will be described later in detail, the corresponding process is executed according to the special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to the gaming state.
The value of the special symbol process flag is updated during each process according to the game state. Further, the CPU normally performs a symbol process process (S308). In the normal pattern process processing,
The corresponding process is executed according to the normal symbol process flag for controlling the lighting of the variable display 18 by the pair of left and right LEDs in a predetermined manner. The value of the normal symbol process flag is also updated during each process according to the game state.

Next, the CPU performs a process of sending a display control command by setting a display control command for a special symbol in a predetermined area of the RAM (special symbol command control process: S309), and a display control command for a normal symbol. A process of sending a display control command by setting it in a predetermined area of the RAM is performed (normal symbol command control process: S31
0). Further, the CPU performs, for example, information output processing for outputting data such as big hit information, start information, and probability variation information supplied to the hall management computer (S31).
1).

Further, the CPU has a solenoid circuit (not shown) in the input / output unit 12 when a predetermined condition is satisfied.
A drive command is issued to (S312). The solenoid circuit drives the solenoid according to the drive command, and the special symbol starting port 6
Alternatively, the special winning opening door 7a is opened or closed. Then, the CPU executes prize ball processing for setting the number of prize balls based on the detection output of the switch for detecting the winning of each prize hole (S313). Specifically, the payout control command is output to the payout control unit 16 in response to the winning detection. A payout control CPU (not shown) mounted on the payout control unit 16 drives a ball payout device (not shown) in response to the payout control command.

With the above control processing, in the present embodiment, the game control processing is activated every 2 milliseconds. Also, until all of the game control processing is executed, it is not in the interrupt enabled state, so other interrupts or the next timer interrupt will not occur, and all the processing during the game control processing is executed reliably. Complete.

FIG. 12 is a flow chart showing an example of a program for special symbol process processing executed by the CPU. The special symbol process process shown in FIG. 12 is a specific process of S307 in the flowchart of FIG.
CPU, when performing the special symbol process process, performs a variation reduction timer subtraction process (S401), and then determines whether the switch of the special symbol starting port 6 (first type starting port switch) is on. (S402). When the first-type starting opening switch is in the ON state (S402; YES), if the number of memory for winning the winning prize is not full, the number of memory for winning the winning prize is incremented by 1 and a random number for jackpot determination is extracted. A starting opening switch passage process is performed (S403). On the other hand, when the first-type starting opening switch is not in the on state (S402;
No), the process of S403 is not performed, and any one of S404 to S412 is performed according to the internal state (special figure flag information). The fluctuation reduction timer is a timer for setting the fluctuation time when the fluctuation time of the special symbol is shortened. The value of the special figure flag information is updated during each process according to the game state.

When the value of the special figure flag information is "00H",
It is determined whether or not the random number value selected in the special drawing game matches the jackpot value, and the "special symbol normal processing" in the normal gaming state such as the processing of notifying it to the outside is executed (S404). When the value of the special symbol flag information is “01H”, the “special symbol stop symbol setting process” for setting the stop symbol in the special symbol game performed on the special symbol display device 4 is executed (S405). The value of special map flag information is "02
When "H", "variable display pattern setting process" for setting the variable display pattern of the symbol of the special figure game performed on the special symbol display device 4 is executed (S406).

When the value of the special figure flag information is "03H",
The "special symbol variation process" for performing the variation process in the special symbol game is executed on the special symbol display device 4 (S40).
7). When the value of the special symbol flag information is "04H", the "special symbol stop process" for decelerating and stopping the special symbol is executed (S408). When the value of the special figure flag information is "05H", the "special winning opening opening preprocessing" for performing the initialization processing for the big hit operation is executed (S409).

When the value of the special figure flag information is "06H",
Various processing relating to the big hit operation and the "large winning opening opening processing" for checking the opening time of the single big winning opening 7 are executed (S410). When the value of the special figure flag information is "07H", the passage of the game ball to the specific area switch is monitored, and "specific area effective time processing" for determining whether or not the special symbol process is executed is executed (S41).
1). When the value of the special figure flag information is "08H", it is determined whether or not the special symbol process is finished, and if it is finished, the demo display (screen during big hit) flag is cleared, the big hit display pattern is cleared, and the big hit end display is displayed. "Big hit end processing" for clearing and clearing information during big hit is executed (S4
12).

Incidentally, each process executed in the special symbol process process is not limited to the above-mentioned process, and may be replaced with another process or further another process may be added. Also, when the processing contents of each processing branched by the value of the special figure flag information are complicated and the processing cannot be completed within the timer interrupt time,
You may make it add several same processes.

In the special figure game, when the game ball passes through the special symbol starting port 6, the special symbol big hit and the loss are determined by the value of the random number for determination. As a result of the determination, when a big hit is displayed, a combination of special symbols corresponding to the value of the random number for determination is displayed on the special symbol display device 4. On the other hand, in the case of losing, a special symbol corresponding to the value of the display symbol random number is displayed.

Below, from the game control section 11 to the display control section 13
The image display processing performed by the display control unit 13 based on the display control command data output to will be described in detail. In addition, in the image display processing by the display control unit 13, if similar image display is apparently performed, it is not always necessary to execute the processing procedure according to the flowchart described below.

FIG. 13 is a flowchart showing the display control process. The display control unit 13 determines whether or not the variation display pattern command is input from the game control unit 11 (S501). When the variable display pattern command is input (S501; YES), a random number extraction process for extracting a random number that determines the type of advance notice effect accompanying the variable display is performed (S502). Next, it is determined whether or not there is an apparent reach effect (S503). When performing reach production (S5
03; YES), it is determined whether or not the reach effect type is super reach (S504). When it is not the super reach (S504; NO), after the normal reach effect display processing (S505) for displaying the image for the normal reach effect on the special symbol display device 4, the main flow is returned to. On the other hand, if it is super reach (S504;
YES), after performing the super reach effect display processing (S506) for displaying the image for the super reach effect on the special symbol display device 4, the process returns to the main flow.

Further, when it is determined in S503 that the reach effect is not performed (S503; NO), it is determined whether or not there is a pending storage of symbol variations (S507). If there is a pending storage (S507; YES), the process directly returns to the main flow, while if there is no pending storage (S507; NO),
It is determined whether or not a predetermined time has elapsed since the symbol variation stopped (S508). When the fixed time has not elapsed (S508; NO), the process directly returns to the main flow. On the other hand, when a certain time has elapsed (S508;
YES), after performing the demo display process (S509) for displaying the demo display image on the special symbol display device 4, the process returns to the main flow.

If no variable display pattern command is input in S501 (S501; NO), it is determined whether or not a big hit is in progress (S510). If it is not a big hit (S510; NO), the process proceeds to S507, while if it is a big hit (S510; YES), the special symbol display device 4 displays information relating to the big hit (number of rounds, big hit symbol, etc.) as an image. Big hit display process for (S51
After performing 1), return to the main flow.

FIG. 14 is a diagram showing a display example when the reach effect display is performed. In addition, this reach pattern is
After reaching the reach, an image of the city is displayed on the special symbol display device 4, and the identification information (two-dimensional image), which is a special symbol, moves fluffy over the city while changing the color and the pattern size. If the special symbol finally stopped on the effective line (the center of the special symbol display device 4) is coincident with the other special symbol which has become the reach pattern, the reach pattern is a big hit.

When this reach pattern is selected, first, as shown in FIG. 14A, the left symbol which is the first stop symbol is replaced and decelerated, and the left symbol '3' is temporarily stopped. Subsequently, as shown in FIG. 14B, the right symbol that is the second stop symbol is replaced and decelerated, and the right symbol '3' is temporarily stopped. Here, the left symbol and the right symbol are in the same symbol and are aligned on the activated line, which is a so-called reach display mode.

In the reach display mode, the entire screen is faded out, and as shown in FIG. 14 (c), the left symbol "3" and the right symbol "3" are reduced and displayed on the upper left side of the display area, and the special symbol is displayed. An image of the city is displayed on the display device 4.

Subsequently, as shown in FIGS. 14 (d) to (g), a number which is a special pattern appears on the front side of the city from the right side of the screen, and the color, pattern, and size are not changed, but are moved up and down and back and forth. Float, move to the left, and repeat the operation of disappearing from the screen while changing the special pattern. Finally, FIG. 14 (h)
As shown in, when the player stops on the effective line at the center of the identification code '3' screen, it becomes a big hit, and a big hit is displayed. On the other hand, in the case of disengagement, special symbols other than '3' stop on the activated line in the center of the screen.

When such a reach pattern display process is performed, the moving special symbol crosses in front of the background buildings and trees, and a part of the background image is hidden behind the special symbol. Conventionally, drawing processing (polygon processing) is also performed for 3D objects that are hidden, and finally,
Hidden surface processing is performed to extract only displayed polygons to generate a display screen.

However, in this embodiment, the VDP 27
As described with reference to FIG. 8, a three-dimensional object (hidden object) that is hidden by another image is excluded from the processing target before the drawing processing is performed, and the processing is performed only on the remaining image. To do. That is, as shown in FIG. 15, in the process of drawing each frame on the VDP, first, a three-dimensional object (hidden object) hidden by a special symbol or another three-dimensional object is discriminated (S701), and the hidden object is detected. Is excluded from the drawing target (S702), and the drawing process is executed only for the remaining three-dimensional object (S703).

By adopting such a processing method, it is possible to reduce the number of three-dimensional objects to be subjected to three-dimensional drawing processing, and it is possible to process an image with a drawing processor having a reasonable capability. Become.

Next, steps S701 and S70 of FIG.
Details of the process executed in 2 will be described with reference to FIG. First, the identification information and the three-dimensional objects arranged in the VDP virtual three-dimensional space (hereinafter, both are collectively referred to as a display object) are sorted in order of distance based on the center position CE (S801). The total number of three-dimensional objects arranged in the virtual three-dimensional space is N.

Subsequently, the pointer I indicating the display object located on the front is set to 1 (S802), and the pointer J indicating the display object located on the back is set to I + 1 (initially 2) (S803).

Next, the inscribed sphere of the I-th display object and the inscribed sphere of the J-th display object are calculated (S
804), from the viewpoint, it is determined whether the inscribed sphere of the Jth display object is hidden by the inscribed sphere of the Ith display object (S805).

When it is determined that the inscribed sphere of the Jth display object is hidden by the inscribed sphere of the Ith display object (S805; YES), the Jth display object is excluded from the drawing target (S805). S806).

Subsequently, it is determined whether or not the pointer J is equal to the total number N of display objects (S807), and when it is determined that they are not equal (J <N) (S807; NO),
J is incremented by 1 (S808), and the process returns to step S804.

On the other hand, when it is determined that the pointer J is equal to the total number N of display objects (J = N) (S807; Y).
ES), that is, whether or not the pointer I is equal to N-1 when it is determined whether or not all display objects located farther than the I-th object are hidden by the I-th object Is determined (S809),
When it is determined that they are not equal (J <N) (S809;
(NO), I is incremented by 1 (S810), and step S803
Return to.

On the other hand, the pointer I is equal to N-1 (J =
N-1) (S809; YES), that is,
For all display objects in the virtual 3D space,
If it is determined whether or not to hide the image, the process ends, and the process proceeds to the drawing process in step S703 in FIG.

The processing operation of FIG. 16 will be specifically described with reference to FIG. FIG. 17 is a plan view of the virtual three-dimensional space, showing a state in which six display objects are arranged in the virtual three-dimensional space. As a result of sorting by distance in step S801, the objects Obj1 are arranged in the order closer to the viewpoint.
It is assumed that the order is from to Obj6.

First, I = 1 and J = 2, and the first display object Obj1 and the second display object O are displayed.
bj2 is selected. Note that the first display object is a special symbol, and itself is a two-dimensional image.

In the illustrated example, the second display object O
The inscribed sphere of bj2 is the first display object Obj1
Do not hide behind the inscribed circle of. A part of the inscribed sphere of the third display object Obj3 is hidden. The inscribed sphere of the fourth display object Obj4 is not hidden at all. Therefore, these display models are not excluded from the processing target.

However, the fifth display object Obj
The inscribed sphere of 5 is completely hidden behind the inscribed circle of the first display object Obj1. Therefore, the fifth display object Obj5 is excluded from the drawing process.

When the process proceeds and I = 2 and J = 6, 6
It is determined that the inscribed sphere of the second display object Obj6 is completely hidden behind the inscribed sphere of the second display object Obj2, and is excluded from the drawing process.

As described above, in the example of FIG. 17, the solid object to be drawn is the solid objects Obj2 and Oj2.
Only bj3 and Obj4 are provided, and the processing amount is significantly reduced as compared with the case where five display objects are drawn.

As described above, by adopting this three-dimensional object drawing method, it is possible to suppress the processing amount while improving the display quality by using the three-dimensional display.

(Modification) In the above processing, if the line of sight is horizontal to the ground surface, the field of view logically reaches infinity, the number of display objects located in the field of view increases, and drawing is performed. There is a risk that the processing amount of the processing will increase.

To solve this problem, as shown in FIG. 18, the line of sight may be set obliquely downward, for example, the field of view may be set obliquely downward so as to look down on the background.
With this setting, the field of view is blocked by the ground, and the depth distance is limited. Therefore, it is possible to reduce the number of display target objects without restricting a complicated visual field.

Further, in the above embodiment, the inscribed sphere is set for the special symbol, but the inscribed sphere or the like is not used for the special symbol (identification information) which is a two-dimensional image,
It may be determined whether or not the stereoscopic image in the background is hidden.

Further, in the above embodiment, the special symbol is a two-dimensional image, but it is of course possible to configure the special symbol with a three-dimensional object. In this case,
As for the special symbol, as shown in FIG. 5B, the radius R of the center and the inscribed sphere is set.

Further, the reach pattern and the like described in the above embodiment can be arbitrarily changed. For example, as shown in FIGS. 19 (a) to 19 (c), a special symbol composed of a solid figure is rotated. Or move while rotating,
Further, as shown in FIGS. 20 (a) and 20 (b), a special symbol with an identification code may be moved / rotated on the screen.

Further, the figure inscribed in the three-dimensional model or the special pattern is not limited to a sphere or a circle, and any shape can be adopted, for example, a cube or a quadrangle.
