Description

The rendering intent of virtual resource object in three-dimensional scenic

Technical field

The present invention relates to field of Computer Graphics, in particular to virtual resource object in a kind of three-dimensional scenic Rendering intent, device, storage medium, processor and terminal.

Background technology

The essence of Real-time Rendering Technology is that the real-time of graph data is calculated and exported.In the situation that computing capability is limited Under, it can rapidly render virtual element true to nature by some simple analogy methods.

In fluid emulation simulation field, the method for more common simulation water can be divided into particle method and gridding method.Grain Sub- method, which splits water body, becomes multiple particles, and by Navier Stokes equation, (describing viscosity in field of fluid mechanics can not press The equation of motion of contracting fluid momentum conservation) or location-based density estimation scheduling algorithm calculate interparticle interaction Power, so as to which particle movement be driven to carry out the effect of simulation water.Grid rule is that water area is divided into grid, also according to receiving The formula such as dimension-stokes equation (are made of to calculate the velocity field of each grid the velocity vector on each moment, every bit Field) and density field (on each moment, every bit density composition field), then again using Rendering algorithms according to density field come Draw water-outlet body.

In game real-time rendering field, especially in game of mobile terminal, since computing capability is limited, water body rendering side Formula only renders the surface of water body.The surface of water body is made of a plane, and by vertex shader, (it is one group of instruction generation Code, this group of instruction code perform when vertex is rendered) carry out the displacement on control plane vertex, so as to simulate the wave of water surface And ripples, then by piece member tinter, (it is one group of instruction code, is performed after vertex shader, and instruction code is used again Calculated in execution diffusing reflection and/or mirror-reflection illumination) to colour for plane, so that the plane seems that approximation one is complete The surface of whole water body.

Water model, rendering and interaction in the application of mobile terminal there is problems：

(1) water body in existing game real-time rendering field is completed based on a plane (i.e. the side of shortage water body) It renders.And in mobile terminal application (for example, AR applications), due to needing dummy object being reasonably placed on real space In, therefore, it is necessary to water body is cut into a stereo block to present.In other words, it can be seen that the side and bottom surface of water body.Thus may be used See, the mode of existing real-time rendering water body cannot be used directly in AR applications.

(2) due to the particularity of AR platforms, virtual water body needs carry out true environment some refractions to enhance void The substitution sense merged in fact, the i.e. background of water body behind are the pictures arrived by game player using photographic device captured in real-time. During AR developments of games, the picture by water refraction is unknown, but the background of the water body behind in common game field It is then known.

(3) water that existing mobile platform is related to more shows as sea, since seawater typically represents the side of scene of game A seawater levels may be used to replace in the not enterable region in boundary, i.e. game player, therefore, seawater, without regard to trip Play player visual angle under water with the situation of Inlet and outlet water, without the interaction situation for considering game player and seawater.However, it is put down in AR On platform, since the handheld device of game player is player visual angle, can be watched in any position in virtual world Dummy object, and then need to consider player visual angle under water, outside water, Inlet and outlet water, the object that game player tosses enters in water, So that seawater present it is different can interaction effect.

(4) the usually used analogy method in fluid simulation field can simulate concept (the i.e. area of simulation water of " body " Domain is an entity rather than a housing), still, this kind of analogy method (is all needed for the consumption of performance is high per frame image Calculate the stressing conditions of each particle and simulate the direction of motion of each particle), so can not apply in mobile terminal.

Above-mentioned electronic equipment can be but be not limited to：Smart mobile phone, headset equipment.

Above-mentioned observation position is virtual camera position.

Optionally, in step s 13, according to first position, the second position and the virtual water body object of observation location determination and The rendering order of default virtual resource object can include step performed below：

Step S131, if the line of the second position and observation position passes through first position, it is determined that default virtual resource pair As being rendered prior to virtual water body object.

The line of the second position and observation position passes through first position, including：The line of the second position and observation position is worn Cross virtual water body object range.In view of it is real solid structure that water body, which is not, but a cube of body case, for this purpose, In water body coloring process, need to perform specific rendering order, i.e., when the line between video camera and default virtual resource object When penetrating water body, these default virtual resource object needs are rendered before water body, to ensure that water body can be implemented to roll over to it Penetrate effect；Otherwise, these default virtual resource objects will render after water body.In addition, delay for depth need not be written Deposit (it is used for the depth for recording each pixel, its object is to：Common depth perception effect is properly generated, i.e. nearby object Body blocks distant objects) object (such as：Particle effect, hundreds of particles ceaselessly convert distant relationships in a small range), The rendering order needs of water body are dynamically adjusted according to video camera relative to the position relationship of water body.The above method can be with Applied to the rendering of the virtual resource object in three-dimensional scenic, for example, three-dimensional scenic virtual resource object in augmented reality system Rendering, can also be applied to other three-dimensional scenics in virtual resource object rendering (for example, 3d gaming).Augmented reality (Augmented Reality, referred to as AR) technology is a kind of position for calculating camera image in real time and angle and adds Respective image, video, threedimensional model technology.This technology aims at：Virtual world is nested in reality on the screen The world simultaneously carries out interaction, can be by the way that true environment and dummy object are superimposed in real time on same picture, thus not only The information of real world can be showed, but also virtual world can be shown, so that two kinds of information are complementary to one another With being superimposed.

Below by with the application in augmented reality, above-mentioned specific rendering order is specifically described.By above-mentioned side Method is applied in augmented reality, needs to consider the rendering to reality scene picture (background frame)；The above method is applied general In logical three-dimensional scenic, then it is not required to consider the rendering of reality scene picture.Firstly, since AR platforms need to reach virtual reality fusion Therefore effect, needs to be used as background and renders to frame buffer at first, for screen institute by the real-time pictures taken by AR equipment Show the direct image of picture, also known as bit map (Bit Map) or grating.Each storage unit of frame buffer corresponds to screen On a pixel, entire frame buffer then correspond to a frame image.

Then, water body can be arranged in opaque article and be rendered later due to being transparent substance.Therefore, water is being rendered During body, water body and the background previously having completed to render, opaque article, partially transparent object write on color in frame buffer into Row mixing.

Since depth buffer is not written in part opaque article, i.e. GPU can be known, and the impermeable of depth buffer is not written The color of bright object, but can not know the position relationship between this kind of opaque article and other objects, therefore, with water body Rendering order needs that dynamic change occurs according to the relative position relation of visual angle and water body.Such as：When video camera and special efficacy ball are equal When above water body, it should first render water body, then render effects ball.When video camera is in water, and special efficacy ball is outside water, it should First render effects ball, then render water body.When video camera and special efficacy ball are all in water, it should first render water body, then render effects Ball.

By controlling rendering order, not only ensure that special cube water column structure can be normal under different visual angles It renders, so that water body is mutually merged with real background, achievees the effect that actual situation combines.

Optionally, the method includes：Rapid S10 captures the image of reality scene by the camera unit of electronic equipment, and Using the image of reality scene as one three-dimensional scenic of background constructing.Can reality scene be captured by the camera unit of electronic equipment Image identifies the characteristic point in the reality scene image, and the three of a realistic space is built on the basis of wherein several characteristic points Dimension coordinate system, and the three-dimensional system of coordinate of realistic space is matched with the three-dimensional system of coordinate of Virtual Space, so as to fulfill with real field The image of scape is one three-dimensional scenic of background constructing, and " actual situation mixed effect " to reach in augmented reality establishes space coordinate base Plinth.In the specific implementation, existing SDK may be used, for example, ARKit.

Optionally, in step S12, an observation position is determined in three-dimensional scenic, including：The display list of the electronic equipment Member is touch-display unit, true in three-dimensional scenic according to the touch control operation for the touch-display unit for acting on the electronic equipment Fixed observation position.It for example, can be according to the click for the touch-display unit for acting on the electronic equipment or ability sliding touch The position (observation position) of virtual camera in operation adjustment three-dimensional scenic.

Optionally, in step S131, determine that the default virtual resource object is rendered prior to the virtual water body object It can include step performed below：

Step S1311 calculates the scalar product of primary vector and secondary vector, obtains the first result of calculation, wherein, first to Amount is to be determined by the center of plane each in top surface and side with default virtual resource object position, secondary vector Normal vector for each plane；

Step S1312 calculates the scalar product of third vector and secondary vector, obtains the second result of calculation, wherein, third to Amount is by the center of each plane and observation location determination；

Step S1313 calculates the vector product of the first result of calculation and the second result of calculation, obtains third result of calculation；

Step S1314, if it find that there are any result of calculations in third result of calculation corresponding with each plane Less than or equal to 0, it is determined that default virtual resource object is rendered prior to virtual water body object；It is otherwise, it determines default virtual Resource object is later than virtual water body object and is rendered.

Assuming that the central point in virtual five faces of water body object is P_i, normal vector N_i, wherein, i=1 represents top surface, i=2-5 Four not ipsilaterals are represented respectively, in addition it is also supposed that default virtual resource object position is P_o, the position of video camera is P_V； Then calculated using equation below：

V_i=((P_o-P_i)·N_i)*((P_v-P_i)·N_i) i=1 ... 5

If for above-mentioned five faces, there is V in one face of any of which_i≤ 0 situation, then it represents that the default virtual resource pair As needing to be rendered prior to virtual water body object；Otherwise, which will be later than virtual water body object and carry out It renders.

The preferred embodiment can specifically include step performed below：

The first step makes virtual water body object.Fig. 2 is the virtual water body object according to a wherein preferred embodiment of the invention Schematic diagram, as shown in Fig. 2, the surface of virtual water body object can be subdivided into the surface mesh of 60*60, for the thin of wave simulated Section.The side of virtual water body object can be subdivided into the surface mesh of 8*4, for the stereoscopic effect of virtual water body object is presented, And the transition effect of side peak without animation and only from deep to shallow.Due to the water body in AR in use, AR can be placed on In the plane detected, therefore, in general, game station will not watch water body, and also consider from water bottom To the rendering performance of transparent substance, so the bottom surface of virtual water body object is removed.

Second step, in virtual water body Object Process is made, respectively each vertex assigns priming color to colour Stage distinguishes the coloring logic on the vertex.Fig. 3 is according to the vertex color configuration schematic diagram of a wherein preferred embodiment of the invention, such as Shown in Fig. 3, each vertex is respectively provided with tetra- Color Channels of RGBA.For positioned at the vertex of top surface, R channels can be set as 1； For the vertex of top half side, G channels can be set as 1；It, can be by channel B for the vertex of lower half portion side It is set as 1.Fig. 4 is according to the spray area schematic of a wherein preferred embodiment of the invention, as shown in figure 4, for remaining A Channel, can be as the mark of special area.Such as：As the mark for rendering spray region.

Third step, before to above-mentioned virtual water body object formally render, need to transparent in water body and scene and The default virtual resource object for not writing depth buffer carries out rendering order rearrangement, is virtually provided with this to ensure that water body and these are default Rendering effect between source object is normal.The foundation of rearrangement is：When the line between video camera and default virtual resource object is worn During Water permeable body, these default virtual resource objects are located at rendering before water body, ensure that water body generates refraction effect to it with this； Otherwise, these default virtual resource objects render after being located at water body.

4th step preloads water body outside and two kinds of different shader codes on the inside of water body, when visual angle is located at outside water body During side (whole region except i.e. virtual water body object coverage area), more rich sea details is presented in water body；When visual angle exists When water-bed (i.e. under sea level and in virtual water body object coverage area), in order to save performance, water body presents simpler Details.Both shader codes automatically switch according to the position at visual angle.

5th step, setting water body rendering state, wherein it is possible to include but not limited to：

(1) setting render-ahead queue is transparent substance, is carried out for ensuring that virtual water body object is later than all opaque articles It renders；

(2) it is transparent to render type, for being determined as the tinter group of tinter distribution；

(3) it closes the back side to cut, the reverse side for determining object from each face is also shown；

(4) depth write is opened, for when drawing water body, the distant relationships of itself and other objects to be notified to GPU；

(5) depth test is opened, for being distal to other notified to GPU's when the specific pixel in discovery certain objects The object of distant relationships, then this pixel will not finally be shown on screen.

6th step, crawl background.In order to fully realize the effect of virtual reality fusion, water body needs to draw the reality that AR takes Face generates certain refraction effect, therefore, before water body is rendered, needs to carry out the content for currently having rendered to frame buffer Crawl, and preserve into a background texture, it is used when water body being waited for render.

7th step, vertex coloring stage.It is main to complete vertex spatial alternation in vertex Shader Stage, wave simulated Vertex animation simulates the vertex animation of interaction ripples and provides required parameter for subsequent first tinter.

The vertex animation of wave simulated can select most popular Gerstner waves at present, compared to other waveforms, The wave crest of Gerstner waves is more acute, and trough is wider, closer to true wave.

The vertex animation of simulation interaction ripples result of calculation is written into textures by script, and then be transferred to tinter. Detailed process performance is as follows：Water body collision body detects the collision of object and water surface, is generated centered on the point of impingement outside The Gerstner waves of diffusion, influence of the wave for each position of the water surface are recorded in specific textures.The color gray scale of the textures Value represents the position of water surface by the influence size of ripples, so as to vertex Shader Stage according to the gray scale of textures come Change the size of vertex fluctuating.

In addition, above-mentioned vertex animation needs the vertex color in second step to distinguish which vertex by vertex animation It influences.Only R channels can just be controlled more than the vertex of 0 (red area) by wave and ripples animation.

8th step, piece member tinting stage.It is main to calculate pixel that water body covered because of the water body color to be mixed, In, the vertex color in second step, the vertex performance of red area is sea characteristic, and what green and blue were showed is then The characteristic of seawater lateral effect.On the outside of the water body mentioned in the 4th step with two kinds of different shader codes of inside, main body Present current procedures.Because in water, the expense of water body piece member coloring becomes very high with pixel full frame shared by water body, but Many details of water surface can not be seen in fact in water.Therefore, the shader code in water can be omitted a large amount of water Body surface details.

The coloration attributes of the water surface are identical with existing water body feature, mainly include：By the rips of textures noise simulation, It is used as the refraction effect of the mixture of colours by the background in the 6th step, bloom effect, the reflecting effect generated by Environment, Fresnel effects, by the breakers along ashore effect of vertex color A channel mark and the mixed effect of color.

The breakers along ashore effect identified by vertex color A channel, due to all remains stationary states of the massif in scene, not The spray is generated to calculate the difference of current coloration depth and existing depth using the existing depth pinup picture by video camera, it is main If consider for performance.

In water intrinsic color device code, the effect of the water surface retains rips and color blending effect.

Water side wall master feature to be used can include：The mixed effect of color, from shallow to deep, the depth of water body gradually increase Greatly, the refraction effect of the mixture of colours and the decorative effect of water body dynamic light beam are used as by the background in the 6th step.
