Inventor: KITAHATA KEI
IPC: G06T13/20
Filed: 2020-03-19
Abstract: To reduce a stereoscopic effect and create movement close to an animation type since movement is created on a three-dimensional space and hence one has a feeling of incongruity in viewing because of a conventional move even if texture of 3DCG can be set to be in an animation type in a conventional animation, more specifically since a conventional 3DCG is created on a three-dimensional space and hence a produced animation has a stereoscopic effect.SOLUTION: In an object 3DCG animation, a method and a program for reducing a stereoscopic effect in viewing are proposed. By transforming a rotary value of an animation to a camera coordinate system and using threshold processing for a minute rotary value, a value can be replaced by another value. At the same time, a stereoscopic effect can be reduced by performing processing for changing a shape of an object, transforming a camera coordinate system to a screen coordinate system, then setting a place that becomes width of each axis, changing a rotary value of an object and a degree of change in a shape from the designated width, and returning the processed value from camera coordinates to a value of an original coordinate system.SELECTED DRAWING: Figure 1
