How to make objects draw transparent/wireframe in the viewport? I have several objects in my scene. I want all the objects to be visible so that I can see how they relate to one another, but I want to focus on just one. To do this, I'd like to make the other objects translucent and non-selectable. I know I can disable selection from the Blender outliner, but there doesn't seem to be an easy way to make just that object transparent. The reason I am trying to do this is simply so that I can see objects in my scene but focus on just the object I am editing.

I'm using glsl with mapcap for rendering and am mainly working in sculpt mode at the moment, and would like to stick with glsl if possible.
You can make an object be displayed as a wireframe by setting the Maximum draw type to wire in Properties editor > Object > Display:



You make an object display as transparent by adjusting the alpha of it's material, and enabling Transparent in the display settings:
