163 | I have also seen in previous posts that the view trihedron in V3d_WIREFRAME mode | |
164 | changes colors depending on the state of the view. This behaviour can be easily | |
2166f0fa | 165 | corrected by altering call_triedron_redraw function in OpenGl_triedron.c of TKOpengl. |
bf75be98 | 166 | The only change needed is to erase glDisable(GL_LIGHTING) that is called before the |
2166f0fa | 167 | Axis name drawing and move this function call just before the initial axis drawing. |
bf75be98 | 168 | Below is the code portion with the modification.I don't know if this is considered to |
2166f0fa SK |
169 | be a bug but anyway i believe it might help some of you out there.*/ |
