152 | I have also seen in previous posts that the view trihedron in V3d_WIREFRAME mode |
153 | changes colors depending on the state of the view. This behaviour can be easily | |
154 | corrected by altering call_triedron_redraw function in OpenGl_triedron.c of TKOpengl. | |
155 | The only change needed is to erase glDisable(GL_LIGHTING) that is called before the | |
156 | Axis name drawing and move this function call just before the initial axis drawing. | |
157 | Below is the code portion with the modification.I don't know if this is considered to | |
158 | be a bug but anyway i believe it might help some of you out there.*/ | |

399 | In the function call_zbuffer_triedron_redraw of TKOpengl, |
400 | the z buffered trihedron changes colors in case there | |

403 | GL_COLOR_MATERIAL is enabled, but only the GL_DIFFUSE | |

405 | This causes the last ambient,specular and emission values | |
406 | used, to stay at the stack and applied to the trihedron | |
407 | (which causes the color change). | |
408 | A fix is proposed , to change GL_DIFFUSE to | |
409 | GL_AMBIENT_AND_DIFFUSE in glColorMaterial call in | |
410 | line 946.The above of course will leave unchanged | |
411 | the SPECULAR and EMISSION values. | |
