Embodiment

[0067] Taking the drawing of a cylindrical pipeline as an example, the circular pipe mainly uses a cylinder as a form of expression. The following introduces several OpenGL functions mainly used in digital modeling of this method:

[0068] auxSolidCylinder(GLfloat radius, GLfloat length)

[0069] The upper bottom surface of the drawn cylinder is fixed, and it is fixed on the plane of y=1.0f in the current coordinate system, taking the y-axis as the axis, and continuously extending toward the negative direction of the y-axis with the specified height. (such as Figure 5 Draw from point C).

[0070] glTranslatef(GLfloat x, GLfloat y, GLfloat z)

[0071] Multiply the current matrix with a matrix representing the moving object. The three parameters represent the displacement values ​​on the three coordinates respectively.

[0072] glRotatef(GLfloat angle, GLfloat x, GLfloat y, GLfloat z)

[0073] Multiplies the current matrix by a matrix representing the rotated object. The ...

Abstract

The invention discloses a method for three-dimensional visualization of a comprehensive pipeline of a metro. The method comprises the following steps of: firstly, extracting comprehensive pipeline data from a comprehensive pipeline drawing; and secondly, carrying out three-dimensional modelling according to the obtained comprehensive pipeline data, and carrying out three-dimensional dynamic displaying on the comprehensive pipeline. In the method for the three-dimensional visualization of the comprehensive pipeline of the metro, a modelling method has digital characteristics and can be edited in a three-dimensional visualization management system; data available for an established three-dimensional pipeline model comes from an auto computer aided design (CAD) drawing; the data is real and reliable; the position information of a three-digital pipeline model in a scene corresponds to the position information of a pipeline in the auto CAD drawing; and the three-dimensional pipeline model is configurable, changeable and manageable.

Description

technical field [0001] The invention belongs to the technical field of computer-related application of subway comprehensive pipelines, relates to a management method for subway comprehensive pipelines, and in particular to a three-dimensional visualization method for subway comprehensive pipelines. Background technique [0002] In recent years, with the development of my country's national economy and the continuous improvement of people's living standards. The traffic situation in large and medium-sized cities in my country is becoming increasingly tense, and road traffic conditions are deteriorating. People have gradually realized that only by developing a large-capacity rapid public transport system with underground railways as the backbone can the problem of urban passenger traffic tension be solved. The design of integrated pipelines is particularly important in the design, construction and later operation and maintenance of subway stations. Therefore, the demand for ...
