I have been writing a game engine for python in C++ using OpengGL. i have loaded a model into the engine and drawn it with texture, normals etc. when i tried to draw the same model in another section of code (where nothing was really different as far as OpenGL was concerned), the model didn't appear. However, it did show up when I drew it with GL_TRIANGLE_FAN, GL_POINTS or GL_LINES, but not with GL_TRIANGLES or GL_TRIANGLE_STRIP.
Basically, is there any reason for something to draw in GL_TRIANGLE_FAN, GL_POINTS or GL_LINES, but not in GL_TRIANGLES or GL_TRIANGLE_STRIP.
I hope this explanation makes sense.

Thanks for the help.
