Description

Rendering System and Methods {RENDERING SYSTEM AND METHOD}

The present invention relates to a rendering system and method, and more particularly, to a technique for producing a moving image by combining the rendered images obtained by distributing the 3D graphic modeling data worked by the worker to the rendering workers (rendering workers).

In general, 3D content rendering represents a task of converting 3D graphic modeling data into image data on a two-dimensional plane. This 3D content rendering is mostly done on a computer with 3D graphic modeling.

However, when 3D content rendering is performed on one computer (equipment), there is a problem that it takes too much time due to the limitation of computing resources.

For example, 3D graphic modeling data includes a large number of frames, which takes about two hours to render one frame. And for a video to feel natural and seamless to the human eye, it needs 24 frames per second.

So if you're making a two-hour animated movie, 2 (hours) * 60 (minutes) * 60 (seconds) * 24 (frames) * 2 (left and right time) = 345,600Hours = 40 (years) Will be taken.

Since a large amount of time is required for rendering in this manner, rendering-only equipment is disclosed. However, such rendering dedicated equipment is expensive and difficult to purchase.

Furthermore, in order to generate video data by combining the rendered images generated as a result of rendering, a separate dedicated program must be purchased.

A rendering system and method for shortening the rendering time of 3D graphic modeling data are proposed.

In addition, a rendering system and method for performing a rendering operation on 3D graphic modeling data without providing rendering-only equipment are proposed.

In addition, a rendering system and method for generating moving image data by combining rendered images without a separate dedicated program for generating moving image data by combining the rendered images are proposed.

 The task scheduling management module may determine rendering workers to perform rendering of the 3D graphic modeling data based on the computing resources of the rendering workers.

The task scheduling management module may include at least one of a processor utilization rate, a number of processors, a processor speed, a memory capacity, a storage medium, an operating system type, a network bandwidth, a network type, a network speed, and a work program type of the rendering worker. The rendering worker to perform rendering of the 3D graphic modeling data may be determined based on a resource.

The rendering manager may further include a rendering worker management module configured to identify and update a state of computing resources of rendering workers to perform the rendering task, wherein the task scheduling management module is configured to determine a state of computing resources of the updated rendering workers. Based on this, it is possible to re-determine rendering workers to perform the rendering operation.

The task scheduling date management module may determine rendering workers to perform the rendering operation based on the 3D graphic modeling data attribute information.

The task scheduling management module performs the rendering operation based on the 3D graphic modeling data attribute information including at least one of a size, a storage position, a frame number, a frame resolution, and a render worker frame number of the 3D graphic modeling data. You can decide which rendering workers to do.

According to another aspect of the present invention, a rendering system includes: a worker terminal configured to transmit 3D graphic modeling data requested for rendering from an operator to a rendering manager; A rendering manager which determines rendering workers to perform rendering of the 3D graphic modeling data and distributes the rendering task of the 3D graphic modeling data; And rendering workers for converting the distributed 3D graphic modeling data into a rendered image using a program specialized for rendering.

The rendering manager may combine rendering images, which are the result of rendering work of the rendering workers, and convert the rendering images into video data.

The rendering workers may combine the rendered images resulting from the rendering work of the rendering workers into video data.

The rendering system may further include a shared database storing the rendered images and the video data.

According to another aspect of the present invention, a rendering task distribution method includes: determining rendering workers to perform rendering operations of 3D graphic modeling data; And distributing rendering work of the 3D graphic modeling data to the determined rendering workers.

The rendering task distribution method may further include converting the images resulting from the rendering tasks of the rendering workers into video data.

The rendering method may include: identifying and updating a state of computing resources of rendering workers to perform the rendering operation; And re-determining rendering workers to perform the rendering task based on the updated computing resources state of the rendering workers.

According to an exemplary embodiment of the present invention, the rendering workers to perform rendering of 3D graphics modeling data are determined to distribute rendering operations of the 3D graphics modeling data, and rendering images that are rendering results of the rendering workers By combining and converting the video data, rendering time of 3D graphic modeling data can be shortened.

In addition, 3D graphic modeling data can be rendered without any rendering-only equipment.

In addition, video data may be generated by combining the rendered images without a separate dedicated program for generating the video data by combining the rendered images.

In addition, each rendering worker 3 may generate the moving image data by combining the rendering images that are the rendering results of the rendering workers who receive the rendering of the 3D graphic modeling data and store the same in the shared database 4. Then, the worker terminal 1 can output the rendered images stored in the shared database 4 through a predetermined image viewer program, or play back the moving image data stored in the shared database 4 using a predetermined video reproducing program.

Therefore, in the rendering system according to the embodiment of the present invention, since the rendering manager device 2 or each rendering worker 3 combines the rendered images to generate the video data, a program for generating the video data by combining the image files separately It does not need to be provided.

In addition, by rendering the rendering work for the 3D graphics modeling data distributed to a plurality of rendering workers, rendering can be performed much faster than the rendering speed when performed on a single computer.
