The formula visit mode of having a glance at being outside one's consideration, and be keen to be actively engaged in, hands-on modern tourism entertainment way.
In real-time rendering engine, because the motion of vivid platform or multidimensional seat is according to moving object or shooting
Machine is checked caused by situation in real time, and during common dynamic movie playback, the dynamic action of film is all changeless, therefore is needed
Vivid platform, multidimensional seat motion algorithm can be produced in real-time rendering engine by wanting one.
The content of the invention
The deficiency for more than, it is an object of the invention to provide a kind of dynamic equipment fortune based on real-time rendering engine
Dynamic computational methods, can be used for the real-time control of single-degree-of-freedom, two-freedom, Three Degree Of Freedom innervation seat and vivid platform.
The purpose of the present invention realized by such technical scheme, a kind of innervation based on real-time rendering engine
Equipment moving computational methods, comprise the following steps：
Step 1：Established in 3D engines with reference to dough sheet and motion dough sheet；
Step 2：Each established with reference to motion idea object F, L and R with reference to dough sheet and motion dough sheet；
Step 3：Move the coordinate position of dough sheet and be consistent towards the coordinate position with moving object and direction；
Step 4：Set X and Z with reference to dough sheet coordinate position consistent with the X and Z of moving object coordinate position, the plane of reference
Piece then adds Y-coordinate offset, and Y-coordinate offset determines according to the stroke of dynamic equipment moving, keeps the coordinate with reference to dough sheet
Position is less than the coordinate position of motion dough sheet, while only allows the Y-axis rotation with reference to dough sheet consistent with moving object, with reference to dough sheet
X-axis, Z axis rotational value remain 0；
Step 5：When moving object setting in motion, moving surface sector-meeting keeps highly consistent with moving object, including rotation
Turn, coordinate, when run-off the straight, displacement variation will be had with 3 points of the L/R/F with reference to dough sheet by moving 3 points of the L/R/F of dough sheet；
Step 6：Subtract each other by the F point Y values for moving dough sheet and with reference to the Y value of the F points of dough sheet, one driving equipment of acquisition
Displacement stroke, similarly, L and R stroke value can be obtained simultaneously.
Further, the layout in the reference motor point in the step 2 and actual vivid platform or the driving equipment cloth of seat
Office is consistent.
Further, the vivid platform or seat driving apparatus are servo electric cylinders.
Further, the moving object in the step 3 includes video camera.
Further, the stroke value of 3 points of the L/R/F is used for the displacement for controlling dynamic equipment.
Due to using above-mentioned technical proposal, the present invention has the advantage that：By being established in 3D engines with reference to dough sheet and
Dough sheet is moved, is each established with reference to motion idea object F, L and R with reference to dough sheet and motion dough sheet, realizes single-degree-of-freedom, two freely
The real-time control of degree, Three Degree Of Freedom innervation seat and vivid platform.
Other advantages, target and the feature of the present invention will be illustrated in the following description to a certain extent, and
And to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, Huo Zheke
To be instructed from the practice of the present invention.The target and other advantages of the present invention can be wanted by following specification and right
Book is sought to realize and obtain.
Brief description of the drawings
The brief description of the drawings of the present invention is as follows.
Fig. 1 is the flow chart of the present invention.
Fig. 2 is that object of the present invention tilts backwards, with reference to dough sheet and motion dough sheet F point change in displacement schematic diagrames.
Fig. 3 is that object of the present invention turns forward, with reference to dough sheet and motion dough sheet F point change in displacement schematic diagrames.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, the invention discloses a kind of dynamic equipment moving calculating side based on real-time rendering engine
Method, comprise the following steps：
Step 1：Established in 3D engines with reference to dough sheet and motion dough sheet, with reference to dough sheet with each being established in motion dough sheet
With reference to motion idea object F, L, R, wherein the driving equipment for the being in the layout of actual vivid platform or seat layout with reference to motor point
Unanimously, as servo electric jar is laid out.F, L and R determines according to actual driving equipment quantity and layout type.
Step 2：The coordinate position for moving dough sheet is consistent with direction with moving object or video camera.
I.e.：
Move the coordinate position of coordinate position=moving object of dough sheet；
Move the direction of direction=moving object of dough sheet；
Step 3：Set the X and Z of the coordinate position with reference to dough sheet consistent with moving object, Y-coordinate is then added with reference to dough sheet
Offset, coordinate offset amount determine according to the stroke of dynamic equipment moving, keep the coordinate position with reference to dough sheet to be less than moving surface
The coordinate position of piece.The Y-axis with reference to dough sheet is only allowed to rotate, X-axis, Z axis rotational value with reference to dough sheet consistent with moving object simultaneously
Remain 0；
I.e.:
With reference to coordinate position=vector (moving object X-coordinate, moving object Y-coordinate-Y-coordinate offset, the motion of dough sheet
Object Z coordinate)
With reference to direction=vector of dough sheet (0, moving object is towards Y, 0)
Step 4：When moving object setting in motion, moving surface sector-meeting keeps highly consistent with moving object, including rotation
Turn, coordinate.When run-off the straight, displacement variation will be had with 3 points of the L/R/F with reference to dough sheet by moving 3 points of the L/R/F of dough sheet.
As shown in Figure 2, by taking F points as an example, when object tilts backwards, the F points of dough sheet and the F point displacements with reference to dough sheet are moved
Become big；
As shown in Figure 3, by taking F points as an example, when object turns forward, the F points of dough sheet and the F point displacements with reference to dough sheet are moved
Become big
Step 5：By taking F points as an example, the F point Y values for moving dough sheet and the Y value of the F points with reference to dough sheet are subtracted each other, obtain one
The displacement stroke (FD) of driving equipment, i.e. FD=motion dough sheets F.Y-refer to dough sheet .F.Y
L and R stroke value can simply be obtained simultaneously with approach described above.
LD=motion dough sheets .L.Y-refer to dough sheet .L.Y
RD=motion dough sheets .R.Y-refer to dough sheet .R.Y
FD/LD/RD is the stroke that dynamic equipment is actually needed motion, by FD, LD, RD value for controlling dynamic equipment
Displacement.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with
The present invention is described in detail good embodiment, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent substitution, and without departing from the objective and scope of the technical program, it all should cover in the present invention
Right among.
