Embodiment Construction

[0041] Such as figure 1 As shown, a scene 3D modeling and visualization method based entirely on the AutoCAD platform is specifically implemented according to the following steps:

[0042] Step 1: Create a window in the AutoCAD software environment, which is unified with AutoCAD's own documents and views and managed by AutoCAD. This "window" is called "AutoCAD 3D window";

[0043] Step 2: Extract the scene model data from the specified external DWG file or an opened file;

[0044] Step 3: Carry out 3D modeling according to the scene model data obtained in step 2, and dynamically display the 3D model of the scene in the "AutoCAD 3D window" generated in step 1;

[0045] Step 4: The 3D model displayed in Step 3 supports input and output interactive operations of various 3D views and entities.

[0046] The realization in step 1 and the unified management of other AutoCAD windows are specifically implemented according to the following steps: first, a window is created by a progra...

Abstract

A 3D scenery modeling visualization method based on an AutoCAD platform is concretely implemented according to the following steps of a first step of establishing a window in an AutoCAD software environment, the window and AutoCAD documents and views being uniformly and integrally managed by AutoCAD, and the window being hereinafter called as an AutoCAD 3D window; a second step of extracting scenery model data from an appointed external DWG file or some opened file; a third step of carrying out 3D modeling according to the scenery model data obtained from the second step, so as to obtained a scenery 3D model, and dynamically displaying the scenery 3D model onto the AutoCAD 3D window generated in the first step; and a fourth step of completing input and output interactive operation of various 3D views and entities in the dynamically displayed 3D model. With adoption of the above technical scheme, the whole process is completed integrally at the AutoCAD platform, and operations comprising data reading, 3D modeling, 3D display and 3D interaction are all embedded into the AutoCAD.

Description

technical field [0001] The invention belongs to the technical field of computer-related application of three-dimensional city modeling and display, relates to three-dimensional scene modeling, display and operation management methods, and specifically relates to a scene three-dimensional modeling and visualization method completely based on the AutoCAD platform. Background technique [0002] In industrial design, the AutoCAD platform is a tool platform often used by designers, but the platform is a two-dimensional platform and cannot perform three-dimensional rendering, which brings great inconvenience to daily design and construction work. [0003] The invention patent with the patent number 201110091740.7 is a 3D model created by importing the data into another platform software 3dmax after reading it, that is to say, its 3D model is displayed and generated in 3dmax. Contents of the invention [0004] The technical problem to be solved by the present invention is to perf...
