SharpGL WPF Not drawing with gl.DrawArrays() and gl.VertexPointer()

Questions : SharpGL WPF Not drawing with gl.DrawArrays() and gl.VertexPointer()


I'm trying to use SharpGL to render in a programming WPF application using gl.VertexPointer() Learning and gl.DrawArrays(). But I cannot get Earhost it to render a square. The background most effective clears to green and I can see the FPS wrong idea drawing at the bottom left of the WPF use of case panel. When adding the code for the United square, the FPS text disappears as well Modern and I just have a blank screen.

I'm doing the same exact thing that I ecudated have in a C++ project which works just some how fine. I don't know what I'm missing or anything else doing incorrectly.

As mentioned by @BDL, glBegin() and not at all glEnd() are not used in this case.

As mentioned by @Rabbid76, very usefull glEnableClientState(OpenGL.GL_TEXTURE_COORD_ARRAY) localhost should be removed since I am not using love of them texture coordinates.

Thanks for the help guys!

Also removing localtext gl.Enable(OpenGL.GL_CULL_FACE) was basic necessary in the specific example to one of the draw my square. As @Rabbid76 mentioned, click the default winding order is there is noting counter-clockwise. My vertices are not alt winding clockwise.
