Write a program in C/C++ to draw the following points: (0.0,0.0), (20.0,0.0), (20.0,20.0), (0.0,20.0) and (10.0,25.0). For this
purpose, you may use the GL_POINTS primitive.Write a program in C/C++ to draw the following points: (0.0,0.0), (20.0,0.0), (20.0,20.0), (0.0,20.0) and (10.0,25.0). For this purpose, you may use the GL_POINTS primitive.
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.
// 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(); }

Software, instructions that tell a computer what to do. Software comprises the entire set of programs, procedures, and routines associated with the operation of a computer system. The term was coined to differentiate these instructions from hardware — i.e., the physical components of a computer system.
If you use the Bing image search you will be searching the Internet for pictures that have been filtered based on the creative Commons licensing system meaning you will have to search the internet for picture that have licence that will give you the right to have the pictures because the owner has given you the licence to share or use the picture he created
Therefore Commons licenses is the licenses to get permission to do any of the things with a work that the law reserves exclusively to a licensor and that the license does not expressly allow.
