If it can't find the answer in it's own cache, it will contact one of the name servers that it was configured to use.
Jenna should NOT provide her routine!!!
hope this helps and have a great day!!
Hello there,

Introductory program; just a static picture of a colored triangle.
Shows how to use GLUT.
Has minimal structure: only main() and a display callback.
Uses only the default viewing parameters (in fact, it never mentions viewing at all). This is an orthographic view volume with bounds of -1..1 in all three dimensions.
Draws only using glColor and glVertex within glBegin and glEnd in the display callback.
Uses only the GL_POLYGON drawing mode.
Illustrates glClear and glFlush.
triangle.cpp
// A simple introductory program; its main window contains a static picture
// of a triangle, whose three vertices are red, green and blue. The program
// illustrates viewing with default viewing parameters only.
#ifdef __APPLE_CC__
#include
#else
#include
#endif
// Clears the current window and draws a triangle.
void display() {
// Set every pixel in the frame buffer to the current clear color.
glClear(GL_COLOR_BUFFER_BIT);
// Drawing is done by specifying a sequence of vertices. The way these
// vertices are connected (or not connected) depends on the argument to
// glBegin. GL_POLYGON constructs a filled polygon.
glBegin(GL_POLYGON);
glColor3f(1, 0, 0); glVertex3f(-0.6, -0.75, 0.5);
glColor3f(0, 1, 0); glVertex3f(0.6, -0.75, 0);
glColor3f(0, 0, 1); glVertex3f(0, 0.75, 0);
glEnd();
// Flush drawing command buffer to make drawing happen as soon as possible.
glFlush();
}
// Initializes GLUT, the display mode, and main window; registers callbacks;
// enters the main event loop.
int main(int argc, char** argv) {
// Use a single buffered window in RGB mode (as opposed to a double-buffered
// window or color-index mode).
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
// Position window at (80,80)-(480,380) and give it a title.
glutInitWindowPosition(80, 80);
glutInitWindowSize(400, 300);
glutCreateWindow("A Simple Triangle");
// Tell GLUT that whenever the main window needs to be repainted that it
// should call the function display().
glutDisplayFunc(display);
// Tell GLUT to start reading and processing events. This function
// never returns; the program only exits when the user closes the main
// window or kills the process.
glutMainLoop();
}
