From 24fcece997ba911b0270033a357bbd83258d4f1a Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Mon, 16 Mar 2009 14:38:27 +0000 Subject: JOGL refactoring: Refactored JOGL into 3 independent components. 1 NWI - Native windowing interface Abstracts the the general NativeWindow interface and it's factory, incl the basic JAWT and Xlib toolkit. The latter was motivated to clean up the JOGL workspace, and to allow other to reuse this part. The generic core is nwi.core.jar, the AWT add-on is nwi.awt.jar. 2 JOGL - The OpenGL mapping Further cleanup of the SPEC. All non OpenGL toolkits are relocated to NWI and NEWT. There is still openmax and the windows audio layer .. Another cleanup of the fixed function pipeline emulation. Moved utilities and implementations where they belong .. Removed GLUnsupportedException. Misc .. changes 3 NEWT - The new windowing toolkit The generic NEWT, newt.core.jar. The JOGL and AWT modules are seperate, newt.ogl.jar newt.awt.jar. Their build can be switched off. The modules source and builds resides in their own directory. Because of their nature, they share the stub_includes, etc. Each module has it's own ant build script - build-nwi.xml - build-jogl.xml - build-newt.xml They can be build at once using build.xml as ususal, which just invokes the seperate build tasks. if rootrel.build=build, then the build location is jogl/build-nwi jogl/build-jogl jogl/build-newt and the sources are under jogl/src/nwi jogl/src/jogl jogl/src/newt Tested: jogl-demos, d4; Linux, MacOsX; Nvidia git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/branches/JOGL_2_SANDBOX@1868 232f8b59-042b-4e1e-8c03-345bb8c30851 --- make/config/jogl/gl-impl-CustomJavaCode-gles1.java | 345 +++++++++++++++++++++ 1 file changed, 345 insertions(+) create mode 100755 make/config/jogl/gl-impl-CustomJavaCode-gles1.java (limited to 'make/config/jogl/gl-impl-CustomJavaCode-gles1.java') diff --git a/make/config/jogl/gl-impl-CustomJavaCode-gles1.java b/make/config/jogl/gl-impl-CustomJavaCode-gles1.java new file mode 100755 index 000000000..a10f8c5e0 --- /dev/null +++ b/make/config/jogl/gl-impl-CustomJavaCode-gles1.java @@ -0,0 +1,345 @@ +public GLES1Impl(GLContextImpl context) { + this._context = context; + this.bufferSizeTracker = context.getBufferSizeTracker(); +} + +public final boolean isGL() { + return true; +} + +public final boolean isGL2() { + return false; +} + +public final boolean isGLES1() { + return true; +} + +public final boolean isGLES2() { + return false; +} + +public final boolean isGLES() { + return true; +} + +public final boolean isGL2ES1() { + return true; +} + +public final boolean isGL2ES2() { + return false; +} + +public final GL getGL() throws GLException { + return this; +} + +public final GL2 getGL2() throws GLException { + throw new GLException("Not a GL2 implementation"); +} + +public final GLES1 getGLES1() throws GLException { + return this; +} + +public final GLES2 getGLES2() throws GLException { + throw new GLException("Not a GLES2 implementation"); +} + +public final GL2ES1 getGL2ES1() throws GLException { + return this; +} + +public final GL2ES2 getGL2ES2() throws GLException { + throw new GLException("Not a GL2ES2 implementation"); +} + +public boolean isFunctionAvailable(String glFunctionName) { + return _context.isFunctionAvailable(glFunctionName); +} + +public boolean isExtensionAvailable(String glExtensionName) { + return _context.isExtensionAvailable(glExtensionName); +} + +public Object getExtension(String extensionName) { + // At this point we don't expose any extensions using this mechanism + return null; +} + +/** Returns the context this GL object is associated with for better + error checking by DebugGL. */ +public GLContext getContext() { + return _context; +} + +private GLContextImpl _context; + +/** + * Provides platform-independent access to the wglAllocateMemoryNV / + * glXAllocateMemoryNV extension. + */ +public java.nio.ByteBuffer glAllocateMemoryNV(int arg0, float arg1, float arg2, float arg3) { + return _context.glAllocateMemoryNV(arg0, arg1, arg2, arg3); +} + +public void setSwapInterval(int interval) { + _context.setSwapInterval(interval); +} + +public Object getPlatformGLExtensions() { + return _context.getPlatformGLExtensions(); +} + +// +// Helpers for ensuring the correct amount of texture data +// + +/** Returns the number of bytes required to fill in the appropriate + texture.
