[osg-users] Invisibility Effect with Material Color Problem
Bonjour, I make a shape disappear by setting an attribute Material with an Alpha equal to 0. I would like to animate its appearance. I increase the Alpha value until 1, but the original color of the shape is not back, rather than that I get a metallic color. What should I do ? thanks ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Your change to createTexture2D breaks the texture caching feature. I believe I understand why you made that change, since the texture wrap modes might be different per texture instance. Maybe a better approach would be to only create a new texture instance if the wrap mode is different? I wish OSG supported setting the wrap mode independently of the texture.

[osg-users] Backporting help from trunk to 2.8.x, osg::State::drawQuads and osg::State::color
Hello OSG users, I'm attempting to backport a patch made in osg trunk (specifically r11768 that fixes some text clipping problems using osgText), and the official trunk patch calls two functions that seem to be not yet present in 2.8. It seems that the call to osg::State::Color() can be replaced by a call to glColor4f(). Is there an equivalent to osg::State::drawQuads()? How was this done before?
