| Post subject: | calling opengl functions |
I'd like to draw some lines in my scene. For this I'd like to use just plain open gl calls for simplicity. However if I do this: glBegin(GL_LINE); //vertices for line glEnd(); the next horde3d::render call will hit an assertion because there is a glError() somewhere in finishRendering(); Any ideas how to get around this? Do I need to call some cleanup code? |

I would assume you are calling some illegal function in between glBegin() and glEnd(). Note that only the vertex specification functions (glVertex*, glNormal*, glTexCoord*, glColor*, and a few others) can legally be called between glBegin and glEnd. |

Sorry for the noise, I should have used GL_LINES instead of GL_LINE, so it always produced the invalid enum error. Thanks anyway for the quick reply! |
