Hi guys,

I wondering about having the constellations lines semi transparent like in pict 2. I think the interest is pretty obvious...



Is this possible or not?

Now to stay in the topic, just an idea for script writers:

What about a script in which we could:
1- select a constellation
2- display the names of all stars participating in the construction of the constellation figure

Is such a script (if possible) of any interest?

You are right. With pointstars rendering which I prefer because it is clean and crisp, many stars are hidden behind the constellation outline.
Colors and transparency are hardwired in the code.
As I believe that you know how to build your own executable, here is the trick.
Open the "render.ccp" source file.
Look for the block which processes asterisms/constellations


change the glColor string into:

The new figures make the lines more transparent (alpha). I put some more blue to compensate for the resultant lower contrast.
Save and build.
Here is the result:

Many Tx Boux, indeed pretty easy to do!!

Dev team? should this little change could be done in the code for further versions?

How about making the OpenGL colors for constellation lines, constellation boundaries and coordinate grid settings in celestia.cfg? I tried that before and might try getting that to work if I could figure out how to make makefiles to compile with mingw. I tried the Microsoft compiler on my new amd 64 system and the linker gave errors about it being on an amd 64 system.
