From e85e3ec2a73ac35aaf911f0b1e34b234be1622da Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Fri, 6 Jul 2012 01:20:48 +0200 Subject: Enhance Bootsrapping of JOGL around 37% - 40% (1st start in new JVM) - GLProfile and GLContext* GLProfile: Enhance bootsrapping performance of loading GL*Impl class - Offthread classloading of all GL*Impl via reflection at startup reduces startup time here around 12% (800ms down to 700ms). GLContext*: Enhance bootsrapping performance of querying available GL profiles - Add PROFILE_ALIASING mode, defaults to true - can be disabled w/ property 'jogl.debug.GLContext.NoProfileAliasing' - PROFILE_ALIASING: If true (default), bootstrapping the available GL profiles will use the highest compatible GL context for each profile, hence skipping querying lower profiles if a compatible higher one is found. Linux x86_64 - Nvidia: 28%, 700ms down to 500ms Linux x86_64 - AMD : 40%, 1500ms down to 900ms - GL*Impl: - make fields final: glProfile, _context, buffer*Tracker and glStateTracker - allow null _context/glProfile in initialization (bootstrapping) - JoglVersion.getDefaultOpenGLInfo(..) - add arg: 'boolean withCapabilitiesInfo', allowing to suppres the list of caps --- make/config/jogl/gl-impl-CustomJavaCode-gles2.java | 18 ++++++++++++------ 1 file changed, 12 insertions(+), 6 deletions(-) (limited to 'make/config/jogl/gl-impl-CustomJavaCode-gles2.java') diff --git a/make/config/jogl/gl-impl-CustomJavaCode-gles2.java b/make/config/jogl/gl-impl-CustomJavaCode-gles2.java index ea6544d29..a4976f5ea 100644 --- a/make/config/jogl/gl-impl-CustomJavaCode-gles2.java +++ b/make/config/jogl/gl-impl-CustomJavaCode-gles2.java @@ -4,9 +4,15 @@ private boolean inBeginEndPair; public GLES2Impl(GLProfile glp, GLContextImpl context) { this._context = context; - this.bufferSizeTracker = context.getBufferSizeTracker(); - this.bufferStateTracker = context.getBufferStateTracker(); - this.glStateTracker = context.getGLStateTracker(); + if(null != context) { + this.bufferSizeTracker = context.getBufferSizeTracker(); + this.bufferStateTracker = context.getBufferStateTracker(); + this.glStateTracker = context.getGLStateTracker(); + } else { + this.bufferSizeTracker = null; + this.bufferStateTracker = null; + this.glStateTracker = null; + } this.glProfile = glp; } @@ -110,9 +116,9 @@ public final GL2GL3 getGL2GL3() throws GLException { // Helpers for ensuring the correct amount of texture data // -private GLBufferSizeTracker bufferSizeTracker; -private GLBufferStateTracker bufferStateTracker; -private GLStateTracker glStateTracker; +private final GLBufferSizeTracker bufferSizeTracker; +private final GLBufferStateTracker bufferStateTracker; +private final GLStateTracker glStateTracker; private boolean bufferObjectExtensionsInitialized = false; private boolean haveOESFramebufferObject; -- cgit v1.2.3
