C++ openGL #11: Draw Triangle Strip

Bismillahir Rahmanir Rahim

Assalamualaikum everyone!! 

_________________________________

Now i'm showing you how draw the Triangle Strip in openGL C++. Its  so easy tutorial just for beginners and basic concept of graph.

Let's enjoy!

>>>Now Create a new project-----

initialize the graph

void Initialize() {
 glClearColor(0, 0, 0, 1.0);
 glMatrixMode(GL_PROJECTION);
 glLoadIdentity();
 glOrtho(-10.0, 10.0, -10.0, 10.0, -10.0, 10.0);
}

glOrtho(-10.0, 10.0, -10.0, 10.0, -10.0, 10.0);

this method,

Declare a 10x10 graph like below ___

Now write code for draw object or lines

At first draw a graph like this one:

Now just put the value on your program between glBegain and glEnd.

when put the vertex on your program you mast follow a sequence  like this

v0->v1->v2->v3->v4

or

v4->v3->v2->v1->v0

void Draw() {
 glClear(GL_COLOR_BUFFER_BIT);
 glColor3d(0,0,0);
 glBegin(GL_TRIANGLE_STRIP);
    glVertex2f(-6.0,-4.0);
    glVertex2f(-6.0,2.0);
    glVertex2f(-3.0,-3.0);
 glVertex2f(-2.0,3.0);
    glVertex2f(0.0,-1.0);
 glEnd();
 glFlush();
}
