Model import method and device

Abstract

The embodiment of the invention provides a model import method and device. The method comprises the steps of: acquiring model central point coordinates of a pre-established three-dimensional stereoscopic model; acquiring camera central point coordinates of a visual region of a stereoscopic camera established in a virtual three-dimensional world; and then importing the three-dimensional stereoscopic model into the virtual three-dimensional world according to the camera central point coordinates, so that the model central point coordinates are coincided with the camera central point coordinatesand the three-dimensional stereoscopic model is placed in the virtual region. Therefore, in the scheme, when the three-dimensional stereoscopic model is imported into the virtual three-dimensional world, the model central point coordinates of the three-dimensional stereoscopic model are coincided with the camera central point coordinates of the visual region of the stereoscopic camera, and the three-dimensional stereoscopic model is placed in the virtual region, so that when the three-dimensional stereoscopic model is imported into the virtual three-dimensional world, the three-dimensional stereoscopic model can carry out display according to a proper size and position to meet display demands of a designer.

Description

technical field [0001] The present invention relates to the field of virtual technology, in particular to a model import method and device. Background technique [0002] With the continuous development of the virtual world, the demand for three-dimensional models is also rising. Various objects in reality are virtualized and added to the virtual world. The fixed model switching by the scene designer may no longer meet the user's imagination. , began to emerge solutions that allow users to choose their own models. [0003] Due to the different design habits and design methods of all model designers, after a 3D solid model is designed and exported to the virtual 3D world, its model grid data will naturally be very different. When imported into the virtual three-dimensional world of the scene designer, various migrations will occur. For the scene designer, before the model is imported, the size and position of the fixed 3D solid model can be preset, but after the import, the ...

Problems solved by technology

For the scene designer, before the model is imported, the size and position of the fixed 3D solid model can be preset, but after the import, the user needs to choose the 3D solid model. The usual processing method obviously cannot meet the display requirements. requirements, the assignment of direct coordinates will also cause the problem that the display of the three-dimensional model is too large or too small, which makes it not meet the designer's requirements
