Hi I installed JOGL 2. I'm using Linux and there exists mesa3d which is open source OpenGL implementation and its version is 7.0.2. At the release note, Mesa version 7.0 supports OpenGL 2.1. When my application call this function: gl.glGetString(GL2.GL_VERSION); it returns this: 1.4 (2.1 Mesa 7.0.2) What does this mean ? Does it mean that my system support only OpenGL 1.4 or .. what? Hence can't I use functions which belong to > OpenGL 1.5 ? sincerely Junyeong |

yes exactly, you can validate it by running glxinfo in a shell. It should report the same version string as JOGL does. e.g output on my old notebook: (...) OpenGL vendor string: DRI R300 Project OpenGL renderer string: Mesa DRI R300 (RV530 71C5) 20090101 x86/MMX/SSE2 TCL OpenGL version string: 1.5 Mesa 7.6 (...) |

Thank you a lot, Michael Bien what about this method? : gl.isExtensionAvailable("GL_VERSION_2_1"); this returns true. and "GL_VERSION_1_5" does too. But gl.glExtensionAvailable("GL_VERSION_3_0"); or > returns false. Does isExtensionAvailable() method has nothing to do with OpenGL actually available for my system? But just relavant to OpenGL library itself? regards. Junyeong |
