hi.. im using Qt 5.3.2 (MSVC 2010, 32 bit) with OpenGL. i want to use 3d display for my project, and i installed QGLViewer and freeglut library. However, the program keep producing recursive paint error when im using glutWireSphere() function. Please help me.. i already used the latest version of freeglut (freeglut-3.0.0.tar) and QGLViewer (libQGLViewer-2.6.3). myqglviewer.h #ifndef MYQGLVIEWER_H #define MYQGLVIEWER_H #include <GL/glut.h> #include <qglviewer.h> class MyQGLViewer : public QGLViewer { public: MyQGLViewer(QWidget *parent = 0); protected: virtual void init(); virtual void draw(); virtual QString helpString() const; }; #endif // MYQGLVIEWER_H myqglviewer.cpp #include "myqglviewer.h" using namespace std; using namespace qglviewer; MyQGLViewer::MyQGLViewer(QWidget *parent) : QGLViewer(parent) { } void MyQGLViewer::init() { // Increase the material shininess, so that the difference between // the two versions of the spiral is more visible. glMaterialf(GL_FRONT_AND_BACK, GL_SHININESS, 50.0); GLfloat specular_color[4] = { 0.8f, 0.8f, 0.8f, 1.0 }; glMaterialfv(GL_FRONT_AND_BACK, GL_SPECULAR, specular_color); glEnable(GL_DEPTH_TEST); glDepthFunc(GL_LESS); glEnable(GL_LIGHT0); glEnable(GL_NORMALIZE); glEnable(GL_COLOR_MATERIAL); glEnable(GL_LIGHTING); restoreStateFromFile(); //help(); } void MyQGLViewer::draw() { //red glColor4f(1.0, 0, 0, 1.0); glTranslated(0, 0, 0); glutWireSphere(0.2,50,50); //blue glColor4f(0, 1.0, 0, 1.0); glTranslated(0.5,0.5, 0); glutWireSphere(0.2,50,50); //green glColor4f(0, 0, 1.0, 1.0); glTranslated(0, 0, 0.5); glutWireSphere(0.2,50,50); } QString MyQGLViewer::helpString() const { QString text("<h2>F a s t D r a w</h2>"); text += "The <code>fastDraw()</code> function is called instead of <code>draw()</code> when the camera "; text += "is manipulated.
