Where are such examples? How can I try an example of OpenGl on my macbook? I've tried to execute "SourceCityGL new" and I got an error "No suitable implementation found for initializing OpenGL context for your platform". No idea why I got this. I have the same error when I try "GLTTRenderingDemo new" I am using Pharo 1.4 Summer. Do I have to install some libraries somewhere? I guess I have OpenGl installed on my mac.

Apparently the background is not updated. Is this intended in your example? Seems so.. an opengl buffer is cleared by fully transparent color: gl clearColor_red: 1 green: 1 blue: 1 alpha: 0; clear: GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT. then, when resulting image transferred back to Display form, it only changes the pixels which is affected, but fully transparent ones will keep background unchanged. The solution is to use opaque color(s) in opengl buffer, or clear background by morph, before copying pixels from opengl buffer.

Hi ! I manually loaded NBOpenGL from SmalltalkHub and SourceCity on moose 4.8, with the default vm proposed on moose's website and it works. There is a sourcecity and GLTest example. image.zip : https://www.dropbox.com/s/4v9m5eig7qs4xez/sourcecity.zip vm : http://www.pharo-project.org/pharo-download/release-2-0 I tested it on win 8 64bit. It'll not work on linux. I don't know about mac os. I will update the ConfigurationOfSourceCity, but i have to write my internship's report for the moment.
