Problems solved by technology

Traditional programs for a single platform have great limitations. When faced with different customer needs, cross-platform systems are more favored by customers
[0003] In addition, the data visualization system proposed in the literature uses the traditional fixed pipeline for image rendering, but the problem with the fixed pipeline is that the degree of programming freedom is low, and the processing of image data must be done by the programmer in the stack. High rate, low rendering efficiency
Its limitation is that it is bloated and runs slightly slower

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0020] Such as figure 1 As shown, the data visualization system based on the Qt framework and the OpenGL programmable pipeline provided by the present invention mainly includes: a data processing platform, a GLSL management platform, and an image visualization platform. Among them, the data processing platform uses asynchronous communication to monitor the input / output ports of the computer. Whenever a custom data packet is read, the data packet is stored through the circular buffer technology, and the data packet is regularly extracted from the circular buffer to check the data packet. Whether the spatial coordinate data in the middle exceeds the spatial boundary of the current coordinate axis in the chart corresponding to the data graph number. When exceeding, update the ...

Abstract

The invention provides a data visualization system based on a Qt frame and an OpenGL programmable pipeline. The system mainly comprises the components of a data processing platform, a GLSL managementplatform and an image visualization platform. The data visualization system is the visualization system which can realize cross-platform operation and furthermore can perform high-efficiency renderingon mass data. Because visualization displaying based on the OpenGL programmable pipeline is utilized, rotation, translation and zooming operation of the mass data can be realized by means of high-speed performance of a GPU, thereby realizing high displaying efficiency. Because a cross-platform Qt frame is utilized, the data visualization system can be used in different systems. Because chart displaying numbers such as coordinate boundary are calculated in real time, adaptive visualization displaying of a two-dimensional image and a three-dimensional image can be performed.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a data visualization system based on a Qt framework and an OpenGL programmable pipeline.
