From 4011e70eed8c88aee0fcd051a50ab3f15bb94f68 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Mon, 13 Feb 2012 07:00:01 +0100 Subject: OpenGL ES/EGL Overhaul - GLProfile properly detects native EGL/ES1/ES2 on the 'desktop' device factory. This allows usage of Mesa's EGL/ES or Imageon's PVR emulation, etc. - GLProfile drops getDefaultDesktopDevice() and getDefaultEGLDevice() since both are aligned by getDefaultDevice(). - Fix GL_ARB_ES2_compatibility detection and utilize resulting isGLES2Compatible() where possible. This allows ES2 compatible desktop profiles to use core ES2 functionality (glShaderBinary() .. etc) even with a GL2ES2 desktop implementation. - EGLDrawable: If createSurface(..) fails (BAD_NATIVE_WINDOW) w/ surfaceHandle it uses windowHandle if available and differs. This allows the ANGLE impl. to work. - Properly order of EGL/ES library lookup: ES2: libGLESv2.so.2, libGLESv2.so, GLES20, GLESv2_CM EGL: libEGL.so.1, libEGL.so, EGL - *DynamicLookupHelper reference will be null if it's library is not complete (all tool libs, all glue libs and a ProcAddressFunc lookup function - if named). - Enhance GL version string (incl. ES2 compatible, hw/sw, ..) - GLBase: Fix docs and remove redundancies - Prepared (disabled) DesktopES2DynamicLibraryBundleInfo to be used for a real EGL/ES2 implementation within the desktop GL lib (AMD). Sadly it currenly crashed within eglGetDisplay(EGL_DEFAULT_DISPLAY), hence it's disabled. --- src/jogl/classes/javax/media/opengl/GLContext.java | 156 ++++++++++++--------- 1 file changed, 87 insertions(+), 69 deletions(-) (limited to 'src/jogl/classes/javax/media/opengl/GLContext.java') diff --git a/src/jogl/classes/javax/media/opengl/GLContext.java b/src/jogl/classes/javax/media/opengl/GLContext.java index 131f42e06..0cf92fb14 100644 --- a/src/jogl/classes/javax/media/opengl/GLContext.java +++ b/src/jogl/classes/javax/media/opengl/GLContext.java @@ -91,26 +91,26 @@ public abstract class GLContext { public static final int CONTEXT_CURRENT_NEW = 2; /** ARB_create_context related: created via ARB_create_context */ - protected static final int CTX_IS_ARB_CREATED = 1 << 0; + protected static final int CTX_IS_ARB_CREATED = 1 << 0; /** ARB_create_context related: compatibility profile */ - protected static final int CTX_PROFILE_COMPAT = 1 << 1; + protected static final int CTX_PROFILE_COMPAT = 1 << 1; /** ARB_create_context related: core profile */ - protected static final int CTX_PROFILE_CORE = 1 << 2; + protected static final int CTX_PROFILE_CORE = 1 << 2; /** ARB_create_context related: ES profile */ - protected static final int CTX_PROFILE_ES = 1 << 3; + protected static final int CTX_PROFILE_ES = 1 << 3; /** ARB_create_context related: flag forward compatible */ - protected static final int CTX_OPTION_FORWARD = 1 << 4; + protected static final int CTX_OPTION_FORWARD = 1 << 4; /** ARB_create_context related: flag not forward compatible */ - protected static final int CTX_OPTION_ANY = 1 << 5; + protected static final int CTX_OPTION_ANY = 1 << 5; /** ARB_create_context related: flag debug */ - public static final int CTX_OPTION_DEBUG = 1 << 6; - /** GL_ARB_ES2_compatibility related: Context is compatible w/ ES2 */ - protected static final int CTX_PROFILE_ES2_COMPAT = 1 << 8; - - /** GLContext {@link com.jogamp.gluegen.runtime.ProcAddressTable} caching related: GL software implementation */ - protected static final int CTX_IMPL_ACCEL_SOFT = 1 << 0; - /** GLContext {@link com.jogamp.gluegen.runtime.ProcAddressTable} caching related: GL hardware implementation */ - protected static final int CTX_IMPL_ACCEL_HARD = 1 << 1; + public static final int CTX_OPTION_DEBUG = 1 << 6; + /** GL_ARB_ES2_compatibility implementation related: Context is compatible w/ ES2 */ + protected static final int CTX_IMPL_ES2_COMPAT = 1 << 8; + + /** Implementation / GLContext {@link com.jogamp.gluegen.runtime.ProcAddressTable} caching related: GL software implementation */ + protected static final int CTX_IMPL_ACCEL_SOFT = 1 << 14; + /** Implementation / GLContext {@link com.jogamp.gluegen.runtime.ProcAddressTable} caching related: GL hardware implementation */ + protected static final int CTX_IMPL_ACCEL_HARD = 1 << 15; private static ThreadLocal currentContext = new ThreadLocal(); @@ -471,13 +471,17 @@ public abstract class GLContext { *
