Thx!Robert! The situation is,we have modified the text.cpp to create some other styles rather than boundingbox.
Like a BoundingLine,one end to one of the corner of a BoundingBox,the other end linked to a osg::Node. So if a text have a BoundingLine and a BoundingBox,I just want draw the BoundingBox as normal,but draw the BoundingLine with LineStipple .So I think one osg::StateSet may not solve this problem. I am not quiet familiar with the openGL programming since I use osg at first.I search the web found people use this code to set Linewidth and Stipple glLineWidth (2.0); glLineStipple (1, 0x0F0F); And I look into text.cpp,found lots of code like use openGL directly,such as : //glClear(GL_STENCIL_BUFFER_BIT); // enable stencil buffer glEnable(GL_STENCIL_TEST); // write a one to the stencil buffer everywhere we are about to draw glStencilFunc(GL_ALWAYS, 1, 1); // write only to the stencil buffer if we pass the depth test glStencilOp(GL_KEEP, GL_KEEP, GL_REPLACE); // Disable writing to the color buffer so we only write to the stencil // buffer and the depth buffer glColorMask(GL_FALSE, GL_FALSE, GL_FALSE, GL_FALSE); // make sure the depth buffer is enabled // glEnable(GL_DEPTH_TEST); // glDepthMask(GL_TRUE); // glDepthFunc(GL_LESS); // Arrrgh! Why does the code only seem to work correctly if I call this? glDepthMask(GL_FALSE); So I think use the openGL code to draw different style may be the qucik way. ... Thank you!
