    problem with viewing entair scene

    how to increase the view area then to see that cube
  3. hi , i am new to opengl.i just created a cube example for small values it is showing the cube properly but when i gave big values to x &y i am un able to see where it is adding to the scne.i just want to see a perticular area in the scene (0,0,100000,100000) my lower left is 0,0 and upper right is 100000,1000000 that much area i want to see ..some one please tell me is there any function to fix this?
  4. could you please send me the code what ever you are trid
  5. in the program i given red for front face but with out rotation it showing yellow(which is back face).sorry for irritating you. #include "glwidget.h" GLWidget::GLWidget(QWidget *parent) : QGLWidget(parent) { rtri = rquad = 0.0f; timer = new QTimer(this); connect(timer, SIGNAL(timeout()), this, SLOT(advancecube())); timer->start(20); } void GLWidget::initializeGL() { glClearColor(1,1,1,1); } void GLWidget::paintGL() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glLoadIdentity(); glTranslatef(1.5f,0.0f,-7.0f); glRotatef( rquad, 0, 0, 1 ); glBegin(GL_QUADS); glColor3f (0.0f,1.0f,0.0f); // Set The Color To Green glVertex3f( 1.0f, 1.0f,-1.0f); // Top Right Of The Quad (Top) glVertex3f(-1.0f, 1.0f,-1.0f); // Top Left Of The Quad (Top) glVertex3f(-1.0f, 1.0f, 1.0f); // Bottom Left Of The Quad (Top) glVertex3f( 1.0f, 1.0f, 1.0f); // Bottom Right Of The Quad (Top) glColor3f(1.0f,0.5f,0.0f); // Set The Color To Orange glVertex3f( 1.0f,-1.0f, 1.0f); // Top Right Of The Quad (Bottom) glVertex3f(-1.0f,-1.0f, 1.0f); // Top Left Of The Quad (Bottom) glVertex3f(-1.0f,-1.0f,-1.0f); // Bottom Left Of The Quad (Bottom) glVertex3f( 1.0f,-1.0f,-1.0f); // Bottom Right Of The Quad (Bottom) glColor3f(1.0f,0.0f,0.0f); // Set The Color To Red glVertex3f( 1.0f, 1.0f, 1.0f); // Top Right Of The Quad (Front) glVertex3f(-1.0f, 1.0f, 1.0f); // Top Left Of The Quad (Front) glVertex3f(-1.0f,-1.0f, 1.0f); // Bottom Left Of The Quad (Front) glVertex3f( 1.0f,-1.0f, 1.0f); // Bottom Right Of The Quad (Front) glColor3f (1.0f,1.0f,0.0f); // Set The Color To Yellow glVertex3f( 1.0f,-1.0f,-1.0f); // Bottom Left Of The Quad (Back) glVertex3f(-1.0f,-1.0f,-1.0f); // Bottom Right Of The Quad (Back) glVertex3f(-1.0f, 1.0f,-1.0f); // Top Right Of The Quad (Back) glVertex3f( 1.0f, 1.0f,-1.0f); // Top Left Of The Quad (Back) glColor3f(0.0f,0.0f,1.0f); // Set The Color To Blue glVertex3f(-1.0f, 1.0f, 1.0f); // Top Right Of The Quad (Left) glVertex3f(-1.0f, 1.0f,-1.0f); // Top Left Of The Quad (Left) glVertex3f(-1.0f,-1.0f,-1.0f); // Bottom Left Of The Quad (Left) glVertex3f(-1.0f,-1.0f, 1.0f); // Bottom Right Of The Quad (Left) glColor3f(1.0f,0.0f,1.0f); // Set The Color To Violet glVertex3f( 1.0f, 1.0f,-1.0f); // Top Right Of The Quad (Right) glVertex3f( 1.0f, 1.0f, 1.0f); // Top Left Of The Quad (Right) glVertex3f( 1.0f,-1.0f, 1.0f); // Bottom Left Of The Quad (Right) glVertex3f( 1.0f,-1.0f,-1.0f); // Bottom Right Of The Quad (Right) glEnd(); } void GLWidget::resizeGL(int w, int h) { double Aspect; // Prevent a divide by zero, when window is too short // (you cant make a window of zero width) if(h == 0)//altura h = 1; // Set the viewport to be the entire window glViewport(0, 0, w, h); Aspect=(double)w/(double)h; //Reset projection matrix stack glMatrixMode(GL_PROJECTION); // Reset the coordinate system before modifying glLoadIdentity(); // gluPerspective(45.0f,Aspect, 1.0, 425.0); double Range = 10; if (w <= h) glOrtho(-(Range),Range,-Range/Aspect,Range/Aspect,-(Range*2),Range*2); else glOrtho(-(Range*Aspect),Range*Aspect,-Range,Range,-(Range*2),Range*2); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); } void GLWidget::advancecube() { rquad++; updateGL(); }
  6. i tried it but i am unable to see the green color..tell me one thing with out rotation and tanslate(static cube)..which face is visible..
  7. Thanks rotation is also working ..i had one doubt with out rotation ,transalation we can see only one side ..which side we can see with out ratation? and also i given green color to the top face but it is not showing green color..but remaining faces it showing different colors which are all i given in the program..some one please tell me why green is not showing..
  8. Thanks for your valuble reply now i am seeing my cube in 3d manner..how to create rotating cube with time
  9. hi, i am new to opengl ..i just started one simple program of creating a cube with different colors in different sides.. i tried with the following code but it showing yellow color square..some one please tell how to make it 3D.. GLWidget::GLWidget(QWidget *parent) : QGLWidget(parent) { rtri = rquad = 0.0f; } void GLWidget::initializeGL() { glClearColor(1,1,1,1); } void GLWidget::paintGL() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glLoadIdentity(); glTranslatef(1.5f,0.0f,-7.0f); glRotatef(rtri,0.0f,1.0f,0.0f); glBegin(GL_QUADS); glColor3f(0.0f,1.0f,0.0f); // Set The Color To Green glVertex3f( 1.0f, 1.0f,-1.0f); // Top Right Of The Quad (Top) glVertex3f(-1.0f, 1.0f,-1.0f); // Top Left Of The Quad (Top) glVertex3f(-1.0f, 1.0f, 1.0f); // Bottom Left Of The Quad (Top) glVertex3f( 1.0f, 1.0f, 1.0f); // Bottom Right Of The Quad (Top) glColor3f(1.0f,0.5f,0.0f); // Set The Color To Orange glVertex3f( 1.0f,-1.0f, 1.0f); // Top Right Of The Quad (Bottom) glVertex3f(-1.0f,-1.0f, 1.0f); // Top Left Of The Quad (Bottom) glVertex3f(-1.0f,-1.0f,-1.0f); // Bottom Left Of The Quad (Bottom) glVertex3f( 1.0f,-1.0f,-1.0f); // Bottom Right Of The Quad (Bottom) glColor3f(1.0f,0.0f,0.0f); // Set The Color To Red glVertex3f( 1.0f, 1.0f, 1.0f); // Top Right Of The Quad (Front) glVertex3f(-1.0f, 1.0f, 1.0f); // Top Left Of The Quad (Front) glVertex3f(-1.0f,-1.0f, 1.0f); // Bottom Left Of The Quad (Front) glVertex3f( 1.0f,-1.0f, 1.0f); // Bottom Right Of The Quad (Front) glColor3f (1.0f,1.0f,0.0f); // Set The Color To Yellow glVertex3f( 1.0f,-1.0f,-1.0f); // Bottom Left Of The Quad (Back) glVertex3f(-1.0f,-1.0f,-1.0f); // Bottom Right Of The Quad (Back) glVertex3f(-1.0f, 1.0f,-1.0f); // Top Right Of The Quad (Back) glVertex3f( 1.0f, 1.0f,-1.0f); // Top Left Of The Quad (Back) glColor3f(0.0f,0.0f,1.0f); // Set The Color To Blue glVertex3f(-1.0f, 1.0f, 1.0f); // Top Right Of The Quad (Left) glVertex3f(-1.0f, 1.0f,-1.0f); // Top Left Of The Quad (Left) glVertex3f(-1.0f,-1.0f,-1.0f); // Bottom Left Of The Quad (Left) glVertex3f(-1.0f,-1.0f, 1.0f); // Bottom Right Of The Quad (Left) glColor3f(1.0f,0.0f,1.0f); // Set The Color To Violet glVertex3f( 1.0f, 1.0f,-1.0f); // Top Right Of The Quad (Right) glVertex3f( 1.0f, 1.0f, 1.0f); // Top Left Of The Quad (Right) glVertex3f( 1.0f,-1.0f, 1.0f); // Bottom Left Of The Quad (Right) glVertex3f( 1.0f,-1.0f,-1.0f); // Bottom Right Of The Quad (Right) glEnd(); rquad-=0.15f; // Decrease The Rotation Variable For The Quad } void GLWidget::resizeGL(int w, int h) { double Aspect; // Prevent a divide by zero, when window is too short // (you cant make a window of zero width) if(h == 0)//altura h = 1; // Set the viewport to be the entire window glViewport(0, 0, w, h); Aspect=(double)w/(double)h; //Reset projection matrix stack glMatrixMode(GL_PROJECTION); // Reset the coordinate system before modifying glLoadIdentity(); // gluPerspective(45.0f,Aspect, 1.0, 425.0); double Range = 10; if (w <= h) glOrtho(-(Range),Range,-Range/Aspect,Range/Aspect,-(Range*2),Range*2); else glOrtho(-(Range*Aspect),Range*Aspect,-Range,Range,-(Range*2),Range*2); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); }
  10. hi, i want to create cube using QT4.3.4...some one please help me with some sample code i want just a stable cube with different colors in different faces of the cube...please help me
