hi…
is they anyone know how to change mouse pointer look to our own graphic.

Simply, get the mouse coordinates (GetCursorPos(&mpos) if on windows) and put a billboarded poly at that coords or better use an orthographic view just to use the same coords as the window.

glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0.0f, width, height, 0.0f, -1.0f, 1.0f);
glMatrixMode(GL_MODELVIEW);

POINT mpos;
ShowCursor(false);

GetCursorPos(&mpos);

glLoadIdentity();
glTranslatef(mpos.x, mpos.y, 0);

Draw a Quad or a triangle strip or something and texture it.
Common, I’f you’re new to openGL, start by lerning the basics, you can’t lern programming with copy 'n paste.
