If you need to install wxPython on Raspbian Buster for a project, the installation of that module can be a little bit tricky. It needs to be compiled for Raspbian from source files to have something working nicely. Here you can find step by step explaination how to do it. Requirements Raspberry Pi Python 3.x time, lots of time Step 1 First, you need to open a terminal (shortcut ctrl + alt + t) sudo apt-get update sudo apt-get install dpkg-dev build-essential libjpeg-dev libtiff-dev libsdl1.2-dev libgstreamer-plugins-base0.10-dev libnotify-dev freeglut3 freeglut3-dev libwebkitgtk-dev libghc

glutCloseFunc without terminating application [closed]

问题 Closed. This question needs debugging details. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . Improve this question I have created a window with glutCreateWindow and started a loop using glutMainLoop . I want to end that loop and close the window so I use glutLeaveMainLoop and glutCloseFunc to destroy it. Automatically, my application terminates. I would like the application to persist after

Removing console window for Glut/FreeGlut/GLFW?

痞子三分冷 提交于 2020-06-09 10:27:30
问题 Under Visual C++, I have played around with Glut/FreeGlut/GLFW. It seems that everyone of these projects adds a CMD window by default. I tried removing it going under: Properties->C/C++->Preprocessor->Preprocessor Definitions From here, I remove the _CONSOLE and replace it with _WINDOWS Then I went under: Properties->Linker->System->SubSystem And I set the option to Windows (/SUBSYSTEM:WINDOWS) Then when I try compiling under GLFW, I get the following building errors: Error 1 error LNK2001:

Threading with glut: glutPostRedisplay being ignored

空扰寡人 提交于 2020-05-15 05:41:18
问题 I have a program which updates it the program output then the state of the program changes. This happens when a ticker of the time (not an openGL timer, one implemented in threads) happens, and when keyboard input is registered from glut (using glutKeyboardFunc callback). Both of these events update the programs state and call glutPostRedisplay; the problem is only the when the keyboard is pressed does it actually do anything. When the timer ticks the display function is ignored, but when the

OpenGL Before you can actually use OpenGL in a program, you must first initialize it. Because OpenGL is platform-independent, there is not a standard way to initialize OpenGL; each platform handles it differently. Non-C/C++ language bindings can also handle these differently.There are two phases of OpenGL initialization. The first phase is the creation of an OpenGL context the second phase is to load all of the necessary functions to use OpenGL. Some non-C/C++ language bindings merge these into one. 简而言之,openGL是一个独立于平台的绘制图形的标准。在你真正能够在程序中使用OpenGL之前,你需要对他进行初始化,但是由于OpenGL是跨平台的,所以也没有一个标准的方式进行初始化

OpenGL Windows 窗口程序环境搭建

OpenGL环境搭建步骤: Downloading OpenGL 根据官网的说法: In all three major desktop platforms (Linux, macOS, and Windows), OpenGL more or less comes with the system. However, you will need to ensure that you have downloaded and installed a recent driver for your graphics hardware. OpenGL 的基础头文件什么的已经随系统提供,然后在安装好显卡驱动就可以下一步了。 Initialization && OpenGL Context Creation 初始化与获取OpenGL Context 方法有两种: 第一种:自己用windows的API写消息循环,获得HWND,然后初始化OpenGL 第二种:使用库,FreeGLUT,自动创建窗口并且获得OpenGL Context 介绍第二种,第一种以后抽时间记录。 首先FreeGLUT自从3.0以后只提供了源码,需要先下载下来然后用Cmake编译成dll。 编译freeglut参照这篇文章: https://blog.csdn.net/yinglang19941010/article

How do I draw a rainbow in Freeglut?

问题 I'm trying to draw a rainbow-coloured plot legend in openGL. Here is what I've got so far: glBegin(GL_QUADS); for (int i = 0; i != legendElements; ++i) { GLfloat const cellColorIntensity = (GLfloat) i / (GLfloat) legendElements; OpenGL::pSetHSV(cellColorIntensity*360.0f, 1.0f, 1.0f); // draw the ith legend element GLdouble const xLeft = xBeginRight - legendWidth; GLdouble const xRight = xBeginRight; GLdouble const yBottom = (GLdouble)i * legendHeight / (GLdouble)legendElements + legendHeight;

C++ OpenGL dragging multiple objects with mouse

问题 just wondering how someone would go about dragging 4 different objects in openGL. I have very simple code to draw these objects: glPushMatrix(); glTranslatef(mouse_x, mouse_y, 0); glutSolidIcosahedron(); glPopMatrix(); glPushMatrix(); glTranslatef(mouse_x2, mouse_y2, 0); glutSolidIcosahedron(); glPopMatrix(); glPushMatrix(); glTranslatef(mouse_x3, mouse_y3, 0); glutSolidIcosahedron(); glPopMatrix(); glPushMatrix(); glTranslatef(mouse_x4, mouse_y4, 0); glutSolidIcosahedron(); glPopMatrix(); I

OpenGL dinosaur model bug: gluTessCallback issue

问题 I am taking a computer graphics class that teaches us how to use OpenGL with the glut libraries. I have an idea for a final project that involves lighting and textures being put on a dinosaur model that I found online. My first step is to simplify the existing online code so I can begin working on my project. Unfortunately, the online code for this model is broken, and I cannot seem to figure it out. I am not sure what gluTessCallback does, but my program is very upset with two lines of this
