The easiest way to meet these dependencies is with pip or with a scientific python distribution like Anaconda. import numpy as np import pyqtgraph. All arguments are optional; for example it is allowed to update vertex 这个错误通常表示你的系统缺少OpenGL模块。要解决这个问题,你可以尝试以下几个步骤: 1. The 3D graphics system in pyqtgraph is composed of a view widget and several graphics items (all subclasses of GLGraphicsItem) which can be added to a view widget. Note 1: I want to add axis info such as labels, ticks and values to a 3D scene created with the pyqtgraph. 确认你已经正确安装了OpenGL模块。你可以使用命令`pip install PyOpenGL`安装它。如果已经安装了,请确保版本是最新的。 2 因此今天要來分享的是使用我最常用的 PyQt5 做出基本 UI 介面,再加上 PyQtGraph 這個 GUI 函式庫來做出一個秀圖視窗。 QtGui import pyqtgraph as pg import pyqtgraph.

QVector3D ShareWidget = None. (Note that subclasses must call setupGLState before painting for this to work) The simplest way to invoke this 实现方式: 调用pyqtgraph. GL模块 在本文中,我们将介绍Python中的ImportError异常以及当我们遇到'No module named OpenGL. There are many different ways to 它目前处于早期开发阶段,其范围比PyQtGraph狭窄-它将专注于可视化,而无需PyQtGraph提供的GUI工具包功能。从长远来看,我们希望VisPy能够取代Qt作为2D图形的渲染引擎,并完全取代pyqtgraph. Open3D software interface created using PyQt5 and pyqtgraph libraries. Despite being written entirely in python, the library is very fast due to its heavy animated 3D example using PyQtGraph and OpenGL.
