The application requires the U.S. Provisional Patent Application Nos.60/631 in submission on November 27th, 2004,196 and the title submitted on November 26th, 2005 for " system and method that is used to show a plurality of views of single 3 D rendering and is used for a plurality of views that background draws " invention people for the U.S. Provisional Patent Application of the Eugene C.K.Lee of Singapore (sequence number is also unknown, but the applicant keep revise the disclosure right so that this sequence number to be provided in the time spent) right.The open of each of these interim individual applications is included in here thus by reference, just as it is illustrated fully.
Technical field
The present invention relates to the interactive three-dimensional visible system, and the system and method that relates more specifically to be used for showing in real time from single 3 D rendering a plurality of views.
Background technology
Volume drawing makes that the user can be by interactive mode visualization of 3 d data set, the threedimensional model of the human body parts that this 3-D data set is for example created according to the section of hundreds of image scanning.In such three-dimensional interactive visualization system, the user can free roam in model, and is mutual and handle this model with this model.Such manipulation is often controlled by hand-held device, this hand-held device allows the user to come certain part of " extracting " 3-D data set, for example be associated with the human organ of giving birth to, for example liver, heart or brain, and for example allow the user to come translation, rotation, modification, boring (drill) and/or add the operation layout data to object.Because the interactive facility of the personal experience in this system, the user need to tend to the reciprocation of a kind of " entering wherein " type, wherein their hand is controlled the action of hand-held interface by certain mode, just as they really enter in the said three-dimensional body, and really personally handle the organ that they see.
Fig. 1 has described such reciprocation.At 110 places, see the 3-D view that on monitor, shows.User expectation " enters wherein " and handles it, but he is shown the front surface obstruction of screen and can not so does certainly.
In order to address this problem, some interactive three-dimensional visible systems once projected to display image on the reflector.At Dextroscope by the Volume Interactions Pte LTd. of Singapore exploitation
TMIn realized such solution.120 places and 130 places at Fig. 1 show such solution.Watch image by showing the user with reference to figure 1,120 via reflector, this reflector reflects this image from side's mounted thereto display monitor.Reflector greatly about with the user's who is seated a trunk and an identical position.By watching the image of reflection, the user can be placed on his hand the reflector back, thereby has " entering wherein " type and the reciprocation threedimensional model that shows of simulation.Though this solution is very suitable for unique user, usually be to watch 3-D data set like this, one of them user's manipulation data, and one or more colleagues of described user look on and watch its manipulation.This for example is common in teaching environment, and in the operation planning problem that cooperation is overcome a difficulty, also be common, wherein cure mainly the surgeon and can require visual professional and technical personnel to be sitting in the control desk place and handle the result that 3-D data set manifests a plurality of surgical methods.
When a plurality of personnel attempted to check the data set of being handled, above-described reflector solution was restricted.This be because for project image onto exactly in such a way make on the reflector its it seems just as the user directly be sitting in the display monitor front identical towards, as as shown in 110, image must reverse in reflector, like this reflection of reverse image become again correct towards.Thus in order to make view that in monitor 110, shows and the view that in reflector 120, shows towards identical, be reflected device 120 reflection the essential projection of monitor oppositely or the image of counter-rotating, like this in reflector 120 reflection once, its can become with at the identical image of not reverse image shown in 110.
With reference to figure 1, view 130 has been described the problem that this technology exists.Interaction console 101 has shown the reflection of the real image that is shown by monitor.This reflection be in correct towards.Therefore, desk-top assistance monitor 102 shows and the identical image of the shown image of monitor that is positioned at interaction console 101 tops.As can be seen, the image in desktop monitor 102 is with respect to the image inversion of seeing in the reflector of interaction console 101, and this has caused not providing information and noninteractive desktop service area for any beholder.
In order to address this problem, interaction console 101 and desktop monitor 102 need to show identical towards.More serious problem is that some interactive three-dimensional visible systems use the stereoprojection of Visualization Model to provide depth cue to the user.The use of stereoprojection has increased the sensation of user for the manipulation of physical threedimensional model, and has also intensified the interactive intuition demand (intuitive need) of user for " entering wherein " type thus.Yet for those people who watches on desktop monitor, it is more difficult than understanding the haplopia field pattern of being inverted demonstration visually to adapt to inverted stereogram.Therefore, owing to the deviation that has increased on function between the reverse image, this technology has been aggravated the problem of counter-rotating screen.In addition, can not use VGA video dispenser (video splitter) to solve this problem simply.Normal VGA video dispenser only duplicates the signal of arrival.They can not realize complicated signal manipulation, for example the mirror image on one or more axles.In addition, signal quality is cut apart and is become poorer along with video each time.
Selectively, existence can be along the more complex video transducer of an axle counter-rotating, and for example, those are used in the video converter that uses in the teleprompter system, but they also are subject to vertical frequency and the screen resolution of being supported.Usually, the maximum perpendicular frequency of being supported is 85Hz.Unfortunately, stereo scene need be watched to avoid flicker by 90Hz or bigger vertical frequency.
Vertical frequency or the refresh rate that is known as more commonly used are measured by hertz (Hz).The quantity of the frame that its expression per second shows on screen.When conversion, have remarkable delay and this interval can be perceived by human eye, then glimmer from a frame to next frame.The people changes along with image brightness for the susceptibility of flicker, but on average, when flicker is 40Hz or when above, falls into acceptable level for the perception of flicker.The optics refresh rate of every eyes is 50-60Hz.Therefore, for stereos copic viewing, refresh rate should be at least 50 * 2=100Hz.
Because this demand, complicated video converter is restricted on vertical frequency.Do not need higher refresh rate, because have the refresh rate that is less than or equal to 85Hz for these inputs that have the transducer of reverse function.Teleprompter (seeing below) does not need 3 d visualization.Their display texts are pointed out the news ewscaster.The example of teleprompter system provides in Figure 1A, can see that wherein screen is by counter-rotating (about X-axis) vertically.
Can comprise that for other potential solutions of this problem sending three-dimensional VGA signal is transmitted back to monitor to the moveable 3-D projecting apparatus and with this signal or it is projected on the screen, the wherein said moveable 3-D projecting apparatus described sight that can on X or Y-axis, reverse.Such projecting apparatus or costliness (and usually heavy) or be subject to original resolution (for example only 800 * 600 Infocus DepthQ projecting apparatus).
People can the custom video transducer in theory, and it can reverse up to the three-dimensional VGA signal of the input of 120Hz, and by identical frequency output, but such customization makes solution become expensive, therefore impracticable.
Because above-described possibility solution or costliness impracticable, heavy and/or that be difficult to bear, the method that needs a plurality of views of the identical 3 D rendering of a kind of real-time demonstration in the art makes each of different views can satisfy different display parameters and user's request.

The system suitability general introduction
Fig. 3 is the exemplary system level figure according to exemplary embodiment of the present invention.In operation, data flow to the right from the left side of figure.
With reference to figure 3, at 310 places, the data that are used to draw can be input to drawing engine 320.From drawing engine 320, can provide a plurality of demonstration outputs, for example CRT 330, free stereo LCD 340 and solid or monoscopic projecting apparatus 350.Therefore, in exemplary embodiment of the present invention, can draw a data set and can show on a plurality of displays that each has the display parameters group of himself these a plurality of displays simultaneously.
Fig. 4 is the program flow diagram according to exemplary embodiment of the present invention.Begin at 401 places, data enter drawing engine 410, its can be for example three-dimensional right according to the Model Calculation projection.
As is known, the human eye of 6-7cm location provides two slightly different scene images to brain approximately at interval.Therefore, solid is made up of two scene images of seeing from different viewpoints (stereo pair).Brain merges this solid to obtaining the sensation of the degree of depth, has caused three-dimensional sensation.
Projection is the process that three-dimensional world and object wherein is mapped to two dimensional image.In perspective projection, pass viewpoint and be mapped on the two-dimensional projection plane from the imaginary light of three-dimensional world.This is to for example similar in the pinhole camera model shown in Fig. 4 A.Every eye will have different projections, because it is watched from slightly different viewpoint.
The solid of having calculated projection to after, drawing engine 410 is exported left image L 411 and right image R 412 respectively.Each of a left side image L 411 and right image R 412 can be imported into back scene processor 420, its solid that can for example handle image to the demand that satisfies a plurality of users as being stored in the scene distributor 450.
From back scene processor 420, can export for example a plurality of data flow, each of these data flow relates to handles the three-dimensional right of image differently.For example, at 431 places, the vertical interlaced scene of left image and right image can be exported to the scene distributor.Similarly, can be at 432 places with the solid of image to being converted to colored complementary color solid (stereo) and offering the scene distributor.Finally, for example, can export the counter-rotating scene at 433 places and be used for using, and, can export and the same scene that in 433, sends at 434 places, but not counter-rotating.
Thus, as shown in FIG. 4, can be in the exemplary output below scene processor place, back produces:
431---the vertical interlaced of left image and right image.This be the free stereo monitor based on as can receive the form that obtains stereoeffect in the lenticular technology shown in Fig. 4 B.
432---the complementary color solid.Final image is RGB.Information in left view is encoded in the red passage and the information in right view is encoded in green passage and the blue channel.Red when putting on-blue or green/red-as during green glasses, to obtain stereoeffect, see the information that is coded in the red passage as left eye (having red filter), and right eye (having the cyan filter) is seen the information of right view.The complementary color solid is used in the three-dimensional movie usually.
433 and 434---the page or leaf exchange is three-dimensional.Wherein left passage and right passage appear in the frame alternately.For example, Dextroscope
TMCan use page or leaf exchange solid or vertical interlaced solid.This solid of two types all needs to block glasses.The vertical interlaced pattern is similar to and uses in Fig. 4 A, but does not wherein relate to the lenticular technology.The horizontal resolution that vertical interlaced has been sacrificed half realizes solid.On the other hand, the page or leaf exchange is three-dimensional provides full screen resolution to eyes.Therefore page or leaf exchange solid provides better three-dimensional quality.
Main difference between above-described exemplary three-dimensional output format is: 431 glasses that do not need the user to be used for seeing; 432 need red-green grass or young crops/red-green glasses; And 433 and 434 need block glasses.
After having provided the right a plurality of outputs 431 to 434 of the identical solid of image, made the scene distributor 450 of configuration, can send to suitable display unit 461 to 464 to suitable input 431 to 434 according to the demand of connected a plurality of display unit.Therefore, for example, can utilize scene distributor 450 that the vertical interlaced scene of left image and right image is sent to auto-stereoscopic display 461.Similarly, the shift scene 432 for the complementary color solid can utilize scene distributor 450 to send to LCD 462.At last, be respectively the reversal data stream and the output stream 433 and 434 of reversal data stream not, can be sent to Dextroscope
TMThe device of type, wherein reversal data stream can be projected on the reflector of interaction console 463, and reversal data stream can not be sent on the auxiliary desktop console 464, is used to allow the colleague who is sitting in the user at interaction console place watch.At last, complementary color stereo data stream 432 or not reversal data stream 434 can alternately send to routine or binocular projector 465 is used to allow a plurality of personnel watch.
Use is equipped with the example of the work station of Nvidia Quadro EX card and realizes
Fig. 5 shows the exemplary realization according to exemplary embodiment of the present invention, and it comprises single draftings that send to two different demonstration outputs.Show that one of output 541 is monoscopic and upright (upright), not counter-rotating just, and another use complementary color red-output of blue three-dimensional display is three-dimensional.Shown realization can for example be used by the work station with NvidiaQuadro FX graphics card.
With reference to figure 5, figure has described the processing that takes place in graphics card 500 and scene distributor 520, and it has produced two outputs 541 and 542.
In graphics card 500, have drawing engine 501 and back scene processor 510.Drawing engine 501 produces a left image and a right image according to the input data.Such input data, for example with reference to figure 4 401 and with reference to figure 3 shown in 310.Left side image and right image, can be for example output to back scene processor, and left thus image and right image can be converted into three-dimensional and vertical interlaced of (a) complementary color and (b) monoscopic (upright) data flow each as illustrating and describe in conjunction with Fig. 4 by drawing engine.
These two data flow can be for example output to scene distributor in the outside operation of this graphics card from graphics card, and the scene distributor can receive three-dimensional right that treatment of picture crosses, and then they is sent it back graphics card, exports via suitable demonstration.Therefore, for example, scene distributor 520 can ask to be used for the image of interaction console output, and just three-dimensional the and vertical reversal data of complementary color flows, and sends it to interaction console output 542 via output port 532.Similarly, scene distributor 520 can ask to be used for the image of desktop output 541, monoscopic erect(ing) image just, and send it to desktop output 541 via output port 531.
Fig. 6 has described according to exemplary two view embodiment of the present invention, and how 1024 * 1536 screen areas can be assigned to two different views, and each is used to produce one of view.Here, for example, screen area 610 can be divided into the sub-screen zone of two 1024 * 768 resolution, and one of them 620 is used to produce the reverse image that the reflector via interaction console shows, another 630 is used to be created in the vertical image that desktop monitor shows.
Show a plurality of possible output streams though should be noted that Fig. 4, do not needed to support simultaneously these data flow.Utilize the more display channels input on the graphics card, three or four views also are fine.But current graphics card only has two display channel inputs usually.
Therefore, utilize two passage graphics cards, example system can have following output stream group:
Interaction console-page or leaf exchange/moveable 3-D;
Desktop console-monoscopic.
Interaction console-page or leaf exchange/moveable 3-D;
Desktop console-complementary color solid.
Interaction console-complementary color solid;
Desktop console-page or leaf exchange/moveable 3-D.
Interaction console-complementary color solid;
Desktop console-monoscopic.
Should be noted that Fig. 6 corresponding to two output streams, for example, one the counter-rotating and another does not reverse.In order to hold, can use more screen area than two more output streams.Yet this has only, and can to check that needed refresh rate is only when supporting desired screen resolution by solid useful.Therefore, this is not only the problem of the memory in video card, still is used to the problem of the support of the video card that disposes, and shows whether output device (monitor, projecting apparatus) can support the problem of this configuration.For the restriction of screen resolution, video card support and refresh rate also play bigger effect.For example, current techniques can not realize 2048 * 2048 of 120Hz.
Use a solid to the exemplary realization on the three-dimensional interactive visible system that is equipped with Nvidia Quadro FX card

The exemplary pseudo-code that is used for the demonstration (left side and right) of a complete stereo scene
In exemplary embodiment of the present invention, following exemplary pseudo-code can be used to realize the demonstration of complete stereo scene.
// be used for the demonstration circulation Foreach Display frame do { switch (DisplayMode) { //see Display Sub-routines case pageflipping stereo:DisplayStereoPageFlipping case red green stereo:DisplayStereoRedGreen case mono:DisplayStereoMono } of interaction console window } // be used for demonstration circulation Foreach Display frame do { Set up orthogonal projection switch (DisplayMode) { the case pageflipping stereo:PasteTextureStereoPageFlipping (mirror yes) of desktop window
Case red green stereo:PasteTextureStereoRedGreen (mirror yes) case mono:PasteTextureMono (mirror yes) } }
Here, rectangular projection represents to represent by two dimensions the method for three-dimensional body.It uses a plurality of views of watching object around the center of object by the viewpoint of 90 ° of increment rotations.Equivalently, view can be considered to obtain by object is rotated by 90 ° of increments around its center.It does not give the sensation of observer's degree of depth.Observe volume as shown in FIG. 7, do not have perspective view.Though the three-dimensional interactive visible system uses the perspective projection of essence usually, and rectangular projection here just is set, texture image can be flattened on the screen like this.
Mirror yes need to represent the indication of image inversion.Fig. 2 and Fig. 4 433,434 shown in exemplary realization in, the interaction console image is the master image of drawing, so be used for the image that the image of desktop console is actual counter-rotating.
// display subroutine DisplayMono foreach eye[left] { SetCurrentBuffer, (pixelbuffer[eye]) SetProj ectionMatrix, (eye) SetModelViewMatrix, (eye) RenderS cene, (eye) SetCurrentBuffer, (framebuffer) Set Orthogonal projection. Bind pixelbuffer[eye] as texture Paste TextureMono, (mirror no) //mirror no==not to flip
Release pixelbuffer[eye] as texture. }
Should be noted that in above-mentioned exemplary pseudo-code, Framebuffer represents the storage space in the video card, is allocated for the realization graphic plotting.Pixelbuffer represents the screen exterior domain and does not want to be used to be presented at screen.The target buffer that Current Buffer specifies follow-up drawing command to influence.Program flow is as follows: make Pixelbuffer as Current Buffer, and scene is drawn in this buffer, can not sees on screen.Next make Framebuffer as Current Buffer, and pixelbuffer is used as texture and is attached among the Framebuffer.Be presented at content on the screen subsequently from Framebuffer.
DisplayStereoRedGreen { SetCurrentBuffer(pixelbuffer[left]) Foreach eye[left，right] { SetProj ectionMatrix(eye) SetModeViewMatrix(eye) RenderScene(eye) } SetCurrentBuffer(framebuffer) Set Orthogonal projection. Bind pixelbuffer[left]as texture Convert texture to grayscale. PasteTextureMono(mirror no) Release pixelbuffer[left]as texture. } DisplayStereoPageFlipping
{ foreach eye[left，right] { SetCurrentBuffer(pixelbuffer[eye]) RenderScene(eye) SetCurrentBuffer(framebuffer[eye]) Set Orthogonal projection. Bind pixelbuffer[eye]as texture PasteTextureStereoPageFlipping(mirror no) Release pixelbuffer[eye]as texture. } }
Should be noted that the present invention finishes a solution, solved by correctly towards and watch the elementary object of desktop monitor image by three-dimensional mode, as shown in FIG. 2.In this solution of exploitation, software solution should be practical as can be seen.Provide the hardware performance of general graphical card, should be noted that being plotted to texture is reliable solution, because do not need twice of scene drawing.In addition, such texture can be used for multiple three-dimensional pattern, as previously mentioned.
Therefore, in order to solve problem in the prior art, need utilize software that two images are plotted in two different monitors.This has caused crossing over two monitors and has come the assignment logic screen area.If select vertical extent (though in exemplary embodiment of the present invention, also can select horizontal-extending), then promoted to be used for the adaptability of intermediate range (mid-range) the LCD monitor of desktop console.(768+768) @120hz (vertical extent) also is fine, but may use 2048 * 768@120hz (horizontal-extending) just cannot by 1024 * 1536 for CRT+LCD combination.Combination will need more expensive high-end LCD monitor for horizontal-extending, and it may need in interchangeable exemplary embodiment.
In exemplary embodiment of the present invention, because being used as extra work, more work finishes (being used in the software neutralization is used in the hardware (graphics card)), may need to use known technology to optimize render speed.
