Re: [Plib-users] Semi-transparent plane

Wolfram Kuss jotted down the following:

> Get a model with transparency,

OK, I tried this.  The cockpit of the Optica model is a solid grey, it is
*not* transparent.  The glass looks like shiny grey plastic.  This is
despite having the lines:

    glEnable(GL_BLEND);
    glEnable(GL_DEPTH_TEST);
    glEnable(GL_ALPHA_TEST);

in the global set-up portion of my code (just after ssgInit() is called).

I also tried Norman Vine's suggestion, using the state/material properties
he posted here.  Again, no transparency, but I can alter the appearance of
the (flat) plane by modifying the GL_EMISSION and GL_SPECULAR properties.
But no transparency.  What's my next move?  I'm sorry to be harking on like
this guys, but I can't make any sense of this and I really *need* this
transparency thing working.
