Projection-based dynamic mapping method

Abstract

The invention provides a projection-based dynamic mapping method. The method particularly includes: step one, mapping each vertex on an object model in a scene to uv coordinates in a dynamic map; step two, drawing the dynamic map, and projecting the drawn dynamic map onto the object model in the scene; step three, according to a depth range of the to-be-shown scene, setting an axial distance between two virtual cameras to guarantee that all objects in the scene are within a proper depth range, and adjusting three dimensions of the objects; step four, aiming at planar materials in the scene, respectively subjecting images, in the two virtual cameras, of the planar materials to displacement transformation to enable depth of field of the planar materials. The projection-based dynamic mapping method has the advantages that changeful three-dimensional models of maps can be made quickly, simply and conveniently, and the effect of depth of field of the planar materials in the scene can be achieved.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional animation, and in particular relates to a projection-based dynamic mapping method. Background technique [0002] Three-dimensional animation technology is a new technology that has emerged with the development of computer software and hardware technology in recent years. It can conveniently and quickly produce three-dimensional animation or film and television special effects shots that meet the needs of directors. [0003] The production principle of 3D animation is generally as follows: First, use 3D animation software (such as 3ds Max, Maya or Houdini) to build a virtual world in the computer; Model; finally, set the animation curve of the model, the trajectory of the virtual camera and other animation parameters, and render the character animation. [0004] Because 3D animation technology has the characteristics of accurately simulating real scenes and almost unlimited creation, it ...

Problems solved by technology

However, compared with 2D movies, 3D has greater technical difficulty and workload

For example, flat materials are often used in post-compositing, which cannot be compatible with 3D technology; the digital inframing technology that can be used in the distant view of 2D movies needs to map the texture uv to the background model in 3D production to render three-dimensional effect; considering the range of sight of the left and right eyes of a person, there is also a limit to the depth of field that can be perceived. If it exceeds the range, you will feel dizzy and uncomfortable
