Hi, I am pretty frustrated. I have a linked list with a set of commands to either draw a block or sphere (from display lists). All the blocks are drawn except one. No idea why. void display( void ) { glClear(GL_COLOR_BUFFER_BIT); list<float>::iterator di=dataList.begin(); for(list<char>::iterator ai=commandList.begin(); ai!=commandList.end(); ++ai) { cout << "CURRENT ITEM: " << *ai << ": " << endl; float x,y,z; switch (*ai) { case 'c' : x = *di; di++; y = *di; di++; z = *di; di++; cout << "color change: " << *di << "," << y << "," << z << endl; glColor3f(x,y,z);//Change the object color break; case 'b' : x = *di; di++; y = *di; di++; z = *di; di++; cout << "block drawn:" << x << y << z << endl; glPushAttrib(GL_ALL_ATTRIB_BITS); glPushMatrix(); glTranslatef(x,y,z); //x,y,z x = *di; di++; y = *di; di++; z = *di; di++; glScalef(x,y,z); glCallList(2); glPopAttrib(); glPopMatrix(); break; case 's' : x = *di; di++; y = *di; di++; z = *di; di++; glPushAttrib(GL_ALL_ATTRIB_BITS); glPushMatrix(); glTranslatef(x,y,z); //x,y,z z = *di; di++; glScalef(1,1,z); glCallList(3); glPopAttrib(); glPopMatrix(); break; }//switch }//for glFlush(); }//void //Initialize world without objects void myInit() { glClearColor (wc1, wc2, wc3, 0.0); createDisplayLists(); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluOrtho2D(worldxBegin,worldxEnd,worldyBegin,worldyEnd); glMatrixMode(GL_MODELVIEW); }//void int main(int argc, char** argv) { glutInit(&argc,argv); glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB); glutInitWindowSize(windowX,windowY); //Center on screen int windowPosx = (glutGet (GLUT_SCREEN_WIDTH) - windowX)/2; int windowPosy = (glutGet (GLUT_SCREEN_HEIGHT) - windowY)/2; glutInitWindowPosition(windowPosx,windowPosy); glutCreateWindow("Hi"); glutKeyboardFunc(keypress); //Exit program when q or ESC is pressed createMenu(); glutDisplayFunc(display); myInit(); glutMainLoop(); return 0; }
