From e122b2f92b2302362569cdc9a67efd5750f46eb1 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Sun, 8 May 2011 05:21:50 +0200 Subject: Graph: GLSL fix, Adding renderModes bits instead of dedicated booleans, Region/GLRegion, .. GLSL fix: - allowing #version tag - add uniform textureSize (ES2) - fix int/float conversion Region/GLRegion: - non OpenGL Region and GL related GLRegion split Region/Renderer renderModes bits (def. in Region) - user creates a Renderer* impl .. and derive Region*'s from outline, possibly from a different code path. - to avoid mode explosion, a bit field is being used for now - Renderer: remove flushCache(), since non caching impl. is intended, or caching by an external user transparent object. --- .../com/jogamp/graph/curve/opengl/GLRegion.java | 125 +++++++++++++++++++++ 1 file changed, 125 insertions(+) create mode 100755 src/jogl/classes/com/jogamp/graph/curve/opengl/GLRegion.java (limited to 'src/jogl/classes/com/jogamp/graph/curve/opengl/GLRegion.java') diff --git a/src/jogl/classes/com/jogamp/graph/curve/opengl/GLRegion.java b/src/jogl/classes/com/jogamp/graph/curve/opengl/GLRegion.java new file mode 100755 index 000000000..20b4d61a1 --- /dev/null +++ b/src/jogl/classes/com/jogamp/graph/curve/opengl/GLRegion.java @@ -0,0 +1,125 @@ +/** + * Copyright 2010 JogAmp Community.
