From 41f0cc8b1a0ab45d6aa05dfe1f5a522317864fd5 Mon Sep 17 00:00:00 2001 From: Kenneth Russel Date: Tue, 8 Jul 2003 09:20:04 +0000 Subject: Added sharing of display lists and textures among OpenGL contexts through new methods in GLDrawableFactory; GLContext has not been exposed in the public API. Tested with new simple TestContextSharing demonstration on Windows, Linux and Mac OS X. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/../svn-server-sync/jogl-demos/trunk@10 3298f667-5e0e-4b4a-8ed4-a3559d26a5f4 --- .../testContextSharing/TestContextSharing.java | 270 +++++++++++++++++++++ 1 file changed, 270 insertions(+) create mode 100644 src/demos/testContextSharing/TestContextSharing.java (limited to 'src/demos/testContextSharing') diff --git a/src/demos/testContextSharing/TestContextSharing.java b/src/demos/testContextSharing/TestContextSharing.java new file mode 100644 index 0000000..88f453a --- /dev/null +++ b/src/demos/testContextSharing/TestContextSharing.java @@ -0,0 +1,270 @@ +/* + * Copyright (c) 2003 Sun Microsystems, Inc.
