I had nothing to do the other day so just for fun I tried to code a simple application that drew objects using different threads. When I tried it though, it showed dots and squares with strange colors. Is there n e way that I can get this to work?

The GL recieves the commands from the different threads at one time an unorderd. So something like this may happen:

glColor3f(..);
glColor3f(..);
glBegin(..);
glVertex3f(..);
glVertex3f(..);
glColor3f(..);
glBegin(..);
glVertex3f(..);

And such a routine causes errors. This may work with multiple contexts. But why do you want to do this?
