Embodiment:
Distributed Real-time Rendering device shown in Figure 1, of the invention, by operating terminal, control centre, rendering execution unit set
At, between each device pass through network communication connect.Operating terminal includes for receiving rendering task and user's operation information
Computer equipment；Control centre includes rendering task distributor, for the scheduling and management to rendering task, and will rendering
The information of task feeds back to operating terminal；Rendering execution unit is made of at least two rendering subelements, for distributing
Rendering subtask rendered, in render process choose LOD level of detail model scene is optimized, reduce scene
Complexity reduces rendering duration using parallel ray tracing scheme, and stores relevant information.
Shown in Figure 2, the workflow of Distributed Real-time Rendering device and method of the invention is as follows:
User submits rendering task, the relevant parameters such as setting subtask size by operating terminal.
Control centre obtains inter-related task information by network communication.According to subtask size by the rendering task of submission into
Row segmentation.Such as the rendering task of submission includes 24 frame animations in total, the subtask size of user setting is 2 frames, then rendering
Task will be divided into 12 rendering subtasks, and each subtask includes 2 frame animations.
Control centre chooses available rendering subelement in rendering execution unit, and these rendering subtasks are distributed
It goes.
Rendering subelement carries out Rendering operations to the subtask distributed.
LOD level of detail model is chosen in render process to optimize scene, reduces the complexity of scene.It utilizes
Parallel ray tracing scheme reduces rendering duration, and saves the various data informations in rendering process.These information are fed back
Go back to control centre.All rendering task information are fed back to operating terminal by control centre.User can be in operating terminal to correlation
Information is managed and inquires.
It is shown in Figure 3, the algorithm structure of LOD level of detail model is described.
LOD algorithm is mainly the clarity difference according to the object in three-dimensional scenic, is generated multiple thin with different levels
The version of section, to realize the purpose to clarity multi-zone supervision.
It is different according to pilot in the process of real-time rendering, suitable LOD model is chosen, details can not damaged
Under the premise of, scene complexity is reduced, improves rendering speed, and accelerate the display rate of scene.
Three-dimensional scenic is analyzed and managed first with Octree algorithm.
Then for different objects and different demands, suitable LOD model is selected.Such as observer in scene
The pel that all can't see anyway, using scalping method, to accelerate rendering speed.Another method is according to the observation and scene
The distance of middle object is selected, and can use relatively rough level of detail apart from remote.It can also be according to the movement of object
Speed selects the model of adaptation, moves faster object, and the details shown on the screen is relatively fuzzyyer, can be used rougher
Level of detail shows.
It is shown in Figure 4, parallel GPU Ray Tracing Algorithm structure is described.
The process of ray trace is exactly the pixel from screen, calculates the direction of light at the point, then herein
Scene is traversed on direction, finally carries out coloring calculating.
Parallel GPU Ray Tracing Algorithm selects simple illumination model, i.e. Phong illumination model.The illumination model can be with
According to the material of object, mirror-reflection (specular) value and diffusing reflection are calculated in the point of intersection that scene and object cross
(diffuse) value, so that it is determined that colouring value.
For leading to the problem of for light, relatively independent basic parameter is generated to each light, includes direction of observation, view
The initial parameters such as angle and light source, viewpoint generate original light using these parameters.
For light and scene Collision Detection, because being closed between pixel without relying on during light coloring
System, so can concurrently coloured to each light.
It, can be in a manner of first using even partition, until triangle number reaches stated number when creating KD-Tree
The partitioning scheme that optimal face is recycled after mesh can effectively improve the efficiency of creation KD-Tree by this scheme.
Finally colored pixels are gathered, obtain rendering result.
The foregoing is merely preferred embodiments of the invention, are not intended to restrict the invention, for the technology of this field
For personnel, the invention may be variously modified and varied.All any modification, equivalent substitution, improvement and etc. made for the present invention,
It should all be included in the protection scope of the present invention.
