Video rendering

Video rendering

Rendering is the process of converting the three-dimensional model into a flat image, suitable for display on monitors or paper. Thus the scene that was constructed in 3D Studio Max goes through rendering and becomes a raster (described by points) image.

Video rendering is a process of rendering a series of images, and combining them into a video with special software.
 
Before rendering 3D-visualization program builds the scene layout at the specified coordinates, captures this layout from positions and in conditions specified by the user. To get a realistic image modeler must put in a set of parameters describing this scene. The more variables entered into the program, the more objects there are in the layout, the longer it will take to render. But the more of these elements you add, the more realistic your scene becomes. Properties of materials, lighting, shadow affect and control the quality of rendering.

Rendering process follows the camera, which the visualizer controls. In most programs, the camera can follow a certain path or the camera may be static with the objects moving in the scene (and sometimes both move).

Camera is the point from which the scene is opbserved. The camera can be configured as if it was real by adjusting the focal length to see the object close up or at a wide angle. You can also adjust the camera's clipping distance, which will determine how close or how far the camera can see, and its depth of field.

Video rendering allows rendering each frame on a separate server. Assuming you spend 5 minutes on rendering one frame, then rendering a 30 second clip will require rendering 30 * 24 = 720 frames and takes 60 hours. Redner farm will render the video on multiple computers at once, reducing the waiting time proportionally to the number of servers. 30 servers can complete the aforementioned task in 2 hours. The more servers used, the faster the rendering process will be.
