GL4Java has it's new _legal_ name: OpenGL[tm] for Java[tm] It's abbreviation may be gl4java .. with the additional trademark hints ! Summary Version 2-5-2-0 testX: =============================== - jdk1.3 and jdk >=1.4 support while implementing the JAWT interface ! - multi threading usage is more reliabel. - code is now 64bit clean, 64bit prepared - Using the new revision makes your existing code incompatible, because: - The GLUFunc.gluNew* etc. methods uses the long type for the reference holder for quadric, tesselation, .. (old: int type) ! This is, because this new revision is completly 64bit clean ! All native reference holders are of type long ! - You did not encapsulate your OpenGL calls within GLContext.gljMakeCurrent GLContext.gljFree e.g. within the GLCanvas.display method: glj.gljMakeCurrent(); // lock GL Context gl.glBegin(); gl.glEnd(); glj.gljSwap(); glj.gljFree(); // release GL Context All the demo's have been updated in the new test release, to work with 2.5.2.0 ! Experience: ========== Linux 2.4.1, XFree86 4.0.2, kde 2.1 beta2: Command-Line JDK (1.1-1.3, sun, blackdown, ibm(no jawt)): OK ! Indirect DRI (Mesa-Soft 3.3): OK NVidia 0.96: OK See NVidia notes below ! Netscape + Netscape JVM: ERROR ! does not work, because Netscape's JVM implementation on linux looks like not to handle long-types within the JNI API .. ?! Netscape + j2re-1_3_0_01: OK ! Indirect DRI (Mesa-Soft 3.3): OK NVidia 0.96: OK See NVidia notes below ! Konqueror (2.1 beta2): jdk 1.3-sun: ERROR Applet runs, but nothing is visible ! jdk 1.3-ibm (no jawt): OK ! jdk 1.3-blackdown: OK ! Indirect DRI (Mesa-Soft 3.3): OK NVidia 0.96: OK See NVidia notes below ! You should disable: - show java console - security manager (java2 itself takes care) Win98/WinNT4.0(*): Command-Line JDK (1.1-1.3, sun): OK ! Well, you have to start the java.exe from the /jre/bin/java.exe Otherwise, the jawt.dll is not found !! BUG in JDK !! IExplorer + MS-JVM buil 3802: OK ! JDirect usage .. JRE 1.3* Plugin + ( IExplorer | Netscape ) OK ! Netscape + Netscape JVM OK ! (*) WinNT 4.0: On my system (servicepack6, nvidia detonator3), i cannot restart the applet ! An read access to adress 0x000000 occures right from NVidia's OGL implementation !! Looks like another bug within NVidia ? See NVidia notes below ! Well, Win98 runs fine NVidia Driver Note's: ==================== The Linux >= 0.9-769 driver works ok ! kind regards, sven
