Coordinate conversion method for Autodesk 3Ds Max three-dimensional model

Abstract

The invention discloses a method for coordinate transformation of an Autodesk 3Ds Max three-dimensional model, which comprises the following steps: firstly, acquiring vertex coordinate information of the three-dimensional model through a 3Ds Max plug-in, and then transmitting the acquired coordinate information of the three-dimensional model through the plug-in and a coordinate transformation system, thereby realizing coordinate transformation. According to the method, coordinate conversion can be efficiently carried out on the 3Ds Max three-dimensional model, data import and export links are reduced, model data information loss cannot be caused, and the complex problem that a monomeric three-dimensional model needs to be converted among different space references in application under 3Ds Max is solved.

Description

technical field [0001] The invention relates to a method for coordinate transformation, in particular to a method for coordinate transformation of a three-dimensional model of Autodesk 3Ds Max. Background technique [0002] Monolithic 3D modeling: In the field of 3D modeling of digital cities, the process of "monolithic" is actually to perform independent and object processing according to the element objects we need, and turn them into pieces that can be processed and edited individually. , and attach the corresponding attribute information. Only such model data can be widely used and managed to realize the transformation of 3D models from "seeing" to "using". Monolithic 3D modeling refers to modeling against geographic entity elements, and each 3D model corresponds to one geographic entity data. [0003] Three-dimensional coordinate transformation: The transformation between two different space rectangular coordinate systems is often involved in theoretical research and ...

In addition, some 3D platforms do not support 3D models in common formats. You need to use the 3Ds Max plug-in to export the 3Ds Max model to the model format supported by the platform, or if you want to modify the 3D model after coordinate conversion, you need to convert the above coordinates After importing the 3D model in common format into 3Ds Max again, the import and export will often result in the loss of some model data information, as well as other setting information of the 3Ds Max model, such as plug-in settings, rendering settings, etc.

[0006] The number of 3D city models is often huge, so the same set of 3Ds Max 3D model data needs to be exported, imported, and coordinate transformed multiple times in different platform applications, which is time-consuming, tedious, and laborious.
