I would like to Develop OpenGL Applications with VB. I used to do it with C++WinApi Programming. The Problem with using it with VB is: How will i insert an OpenGL view port in VB. I used Tao to Make a View port. I initialized its Contexts. Everything was fine Except the Output Was Terrifically Ridiculous.
for Eg: if I give a simple code:
                   glClearColor(0.0, 0.0, 0.0, 0.0)
                   glClear(GL_COLOR_BUFFER_BIT)
                   glColor3f(1.0, 1.0, 1.0)
                   glOrtho(−1.0, 1.0, −1.0, 1.0, −1.0, 1.0)
                   glBegin(GL_POLYGON)
                   glVertex2f(−0.5, −0.5)
                   glVertex2f(−0.5, 0.5)
                   glVertex2f(0.5, 0.5)
                   glVertex2f(0.5, −0.5)
                   glEnd()
                   glFlush()
the normal output must be like a White Rectangle, the output is like some Deformed Polygon.
I know Tao is Usually used with C#.What will I do with VB. thanks IN advance!!

Solution 1

I think the glBegin(GL_POLYGON) is wrong. Change it into glBegin(GL_TRIANGLES)
