In the projection scene that has the contained angle between the screen, compare in the fusion effect of a plurality of screens of prior art angulation not good, this application is through cutting into the panorama view cone that all screens formed with the observation point and all screens into a plurality of sub view cones with screen one-to-one, accomplish the projection of each screen respectively under the context three-dimensional display environment of each sub view cone for all be the continuation of field of vision and space between the adjacent screen, a large projection range that a plurality of screens are constituteed is a coherent three-dimensional space projection, the screen junction does not have the folding sensation, make the observer look at once and go each screen to same plane space of same screen, produce only one large screen and be using as the visual effect of show.
On the basis of the above-described embodiment:
as a preferred embodiment, the process of respectively configuring the contextual three-dimensional display environment of the N sub-view cones according to the display area information of the N sub-view cones specifically includes:
respectively determining parameters of glFrustum () according to the display area information of the N sub-view cones;
calling glfrustutum () configures the context three-dimensional display environment of the N sub-view cones, respectively.
Specifically, the perspective projection method is to observe an object through a transparent body, a transparent plane is set between people and the object, and is called a picture (i.e., a projection plane), the position of human eyes is called a viewpoint (i.e., a projection center), a line is connected from the viewpoint to each point on the object and is called a sight line (i.e., a projection line), the intersection point of each sight line and the picture is the perspective projection of each point on the object, and the projection of each point is connected, so that the perspective of the object is obtained. Obviously, the viewing cone of the viewpoint in this application uses perspective projection.
The perspective projection method is expressed in two modes of symmetry (realized by using the interface glu Peractive) and asymmetry (realized by using the interface glFrustum) in the OpenGL graphic interface. Considering that the sub-view cones divided into are generally asymmetric sub-view cones in general, the present application calls glfrustutum () to configure a contextual three-dimensional display environment. Of course, if the complete panoramic view cone is formed by splicing the symmetrical sub-view cones, the method can also directly call glu _ perspective () to configure the context three-dimensional display environment, and is simple and convenient.
As a preferred embodiment, the parameters of glfrustutum () are specifically the up, down, left, right, near, far information of the sub-view cone.
Specifically, the parameters of glfrustumum () are the up, down, left, right, near, and far information of the sub view cone, that is, the size value length and width of the display area and the far and near screenshot values.
As a preferred embodiment, the process of completing the projection of each screen in the context three-dimensional display environment according to the projection instruction is specifically as follows:
analyzing the projection instruction into a drawing command in a context three-dimensional display environment;
finishing the drawing of the projection content corresponding to each screen according to the drawing command;
and projecting the drawn projection content to a corresponding screen.
Specifically, in order to improve performance, the method and the device only draw objects intersected with the view cones, analyze received projection instructions input by a user into drawing commands in the context three-dimensional display environment of each sub-view cone, and then finish drawing of projection contents corresponding to each screen according to the drawing commands, so that the drawn contents projected on each screen are consistent with to-be-projected contents corresponding to panoramic view cones formed by observation points and all screens.
As a preferred embodiment, the drawing commands are embodied as hybrid drawing commands.
Specifically, the visualization of the three-dimensional data scene can be realized by selecting mixed rendering, and the mixed rendering is the combination of surface rendering and volume rendering. The surface drawing firstly constructs an intermediate geometric primitive (such as an isosurface and the like) from a three-dimensional data scene, and then realizes the drawing of the surface by utilizing the traditional computer graphics technology. Volume rendering does not require the construction of intermediate geometric primitives, and two-dimensional images on a screen are directly generated from a three-dimensional data scene. The mixed drawing not only utilizes the whole information and the characteristics of the volume drawing reflection data, but also utilizes the surface drawing to display a clear important interface, and integrates the advantages of two methods of the volume drawing and the surface drawing, such as representing bones through the surface drawing, and representing structures such as muscles, blood vessels and the like through the volume drawing.
As a preferred embodiment, when the projection of each screen is controlled by the projection devices corresponding to the screens one to one, after the context three-dimensional display environment of the N sub-view cones is configured, before receiving a projection instruction input by a user, the method further includes:
and configuring a network communication environment, and synchronizing the space coordinates of the observation points acquired by each projection device.
Specifically, the projection of each screen can be controlled by one projection device, so that the method is simple and efficient, and the resource occupation of the projection device is saved. Of course, the projection of each screen can also be controlled by the projection devices corresponding to the screens one by one, so that the projection content of each screen can be conveniently adjusted. When each projection device respectively controls the corresponding screen, the spatial coordinates of the observation points acquired by each projection device may not be synchronous, so that after the context three-dimensional display environment of each sub-view cone is configured, before the projection instruction input by the user is received for projection, the network communication environment is also configured, and the spatial coordinates of the observation points acquired by each projection device are synchronized. Specifically, the configuration of the network communication environment may be implemented by using a socket byte-encoding technology or a TCP (transmission control Protocol), and of course, other manners may also be used.
As a preferred embodiment, the process of receiving a projection instruction input by a user and completing projection of each screen in a context three-dimensional display environment according to the projection instruction specifically includes:
setting a projection device corresponding to a main screen selected by a user as a main projection device;
the main projection device receives a projection instruction input by a user and sends the projection instruction to other projection devices;
and each projection device respectively completes projection of each screen under the context three-dimensional display environment according to the projection instruction.
Specifically, when each projection device controls a corresponding screen, one screen corresponds to one projection device, and the imaging of one sub view cone is the content displayed by one projection device, where the projection device may be a computer. In order to simplify the control steps, the projection device corresponding to the main screen selected by the user is set as the main projection device, the main projection device only needs to receive the projection instruction input by the user, then the main projection device and other projection devices carry out reliable TCP communication, and the received projection instruction is automatically sent to other projection devices, so that the function of controlling the use conditions of all screens by only controlling the main projection device is realized.
For the convenience of understanding of the present application, the following describes a multi-screen fusion method provided by the present application with reference to specific examples:
referring to fig. 2, fig. 2 is a schematic diagram of a two-screen cone segmentation method according to the present invention.
In this example, there are two screens, i.e. a vertical screen and a horizontal screen, which are the same in size, and have a length of 12M and a width of 8M, and an included angle of 90 degrees. The vertical distance belowVertical from the observation point to the vertical screen is 5M, and the vertical distance frontVertical from the vertical screen is 6M. The observation point is in the middle position of bilateral symmetry, that is to say the distance between the observation point and the left boundary of the vertical screen and the horizontal screen is equal to the distance between the observation point and the right boundary of the vertical screen and the horizontal screen.
The panoramic view cone formed by the observation point and the vertical screen and the depression screen is formed by splicing two sub view cones, and the visual line of the sub view cone corresponding to the vertical screen and the visual line of the sub view cone corresponding to the depression screen need to form a 90-degree included angle to be complementary with the 90-degree included angle formed by the vertical screen and the depression screen so as to avoid losing projection content. It can be seen that the two sub-view cones are not symmetrical sub-view cones, so that the application calls the glfrustutum interface to set the glFrustum (left, right, bottom, top, nearVal, farVal) parameters of the two sub-view cones respectively.
And (3) projecting a corresponding sub view cone on a vertical screen: right-left-length/2 (symmetrical in the middle of position), top-front, bottom-width;
right-left-length/2 (symmetrical in the middle of position), top-width-belowVertical, bottom-belowVertical; wherein, nerValih is smaller than farVal, and the value is set according to the relation without participating in the calculation of the design.
And synchronizing the coordinate spaces of the two screen observation points, and fixing the viewing angles of the two sub viewing cones to form a 90-degree difference value. The depression screen is set as a main screen, the computer projected to the depression screen is a main computer, and the main computer is connected with the computer projected to the vertical screen. And the third application control program is connected with the computer corresponding to the main screen, and the programs of the computers corresponding to the downward screen and the vertical screen are controlled in a command input mode. Of course, the third application control program may not be connected, and the programs of the computers corresponding to the downward screen and the upward screen may be directly controlled by the computer corresponding to the main screen.
Referring to fig. 3, fig. 3 is a schematic view illustrating a multi-screen fusion effect of the two-screen view cone shown in fig. 2, and it is obvious that the application realizes continuation of views and spaces between the vertical screen and the horizontal screen, and the screen joint has no folding sense, so that a visual effect that only one large screen is used for display is generated, and the application can better and more conveniently serve related industries and society.
