Re: [osg-users] [3rdparty] Installing osg for Android on Windows (Eclipse)
Hi, Jorge Thanks for your advice! After learning all the basic thing about linux and android programming, I successed in building osg for android and tested the sample with my android phone. As an absolute novice, it's really a long journey. For other newbies like me, i have found a easy to follow tutorial: http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2012-March/057074.html Another problem: if i want to develope some big project just like osgVirtualPlanet or osgEarth for android, what is the best IDE for this task? Since the only IDE i'm familiar with is visual studio, i have searched something similiar with it but couldn't find any useful info. Maybe eclipse cdt? Thank you!

Re: [osg-users] [3rdparty] Installing osg for Android on Windows (Eclipse)
Hi, Jordi I had read the linked page in your post carefully, but still can't figure out how to build osg for android on windows. Since i have learned android development only recently, i'd like to ask something more concrete. When building for android on win7, could i generate project file with CMake gui, just like generating sln file for windows? What kind of tools should i choose? I have successfully built and run android ndk sample in eclipse, but i noticed that it built c++ files with cygwin and gcc and generated so file rather than dll. Should i built osg with cygwin? I have googled this issue extensively, but no any useful information for newbies lke me. Wang Rui's new book has some information on this issue, but only on linux. ... Thank you!

Re: [osg-users] Problem with osgEarth::ImageOverlay::setAlpha
Hi, The bug has been found in ImageOverlay::init() method. The original code is: osg::Vec4Array* colors = new osg::Vec4Array(1); (*colors)[0] = osg::Vec4(1,1,1,_alpha); geometry-setColorArray( colors ); geometry-setColorBinding( osg::Geometry::BIND_OVERALL ); when change it to: osg::Vec4Array* colors = new osg::Vec4Array(4); (*colors)[0] = osg::Vec4(1,1,1,_alpha); (*colors)[1] = osg::Vec4(1,1,1,_alpha); (*colors)[2] = osg::Vec4(1,1,1,_alpha); (*colors)[3] = osg::Vec4(1,1,1,_alpha); geometry-setColorArray( colors ); geometry-setColorBinding( osg::Geometry::BIND_PER_VERTEX ); the alpha value are applied correctly. I don't know if it a bug in osg core library. ... Thank you!

[osg-users] Problem with osgEarth::ImageOverlay::setAlpha
Hi, I use osgEarth::ImageOverlay::setAlpha(float alpha) to change the transparency of images, which was draped on terrain, just like what google earth does, but this method seems has no effect at all! It also doesn't work in the sample osgearth_imageoverlay. Is it a bug? I use openscenegraph 3.0.0 and osgearth 2.1.1, build with visual studio 2010. Thank you!
