Transparent crystal effect?

Ok, I'm pretty much goofing off at this point, and have concocted a modification of a starfighter with a phasor (a laser amplified by a refined crystal), and I'm trying to give it a colorful effect.

The outer shell is a semi-transparent cone with a jet black color, along with another semi-transparent cone with a dark purple shine... a Dark-Energy Phasor, if you will. But I am having problems with trying to make the dark purple cone visible, because the moment it submerges into the larger Black cone, it tends to disappear completely. I've tried resizing the cones to compensate, and even though it's helped, half of the crystal is still not appearing (it's two cones each, backs against one another).

These sort of slight little annoyances are usually the harder problems to solve sometimes, but I'm hoping anybody will have some ideas as to how to rectify the problem (namely Dr. Jim.... he's omniscient! ).

Any help on this problem is greatly appreciated!

Edit: For those of you who still use Cathode Ray monitors, you may have to boost your monitor's brightness a little...

Not on even numbered Saturdays apparently - don't understand the problem. The purple cone is the thingy in the middle of the picture - very visable.

Couldn't come up with any way to make it disappear when I tried what I thought you were doing. Need more details or the code that's giving the problem.

My bad... I probably wasn't clear enough about what I was talking about...

Here.... I've circled the area where I'm talking about.

The two inner cones are back-to-back, like the outer ones are. However, the rear cone cuts in half when it is placed a certain way into the rear outer cone. What I'm trying to do is to make the rest of it visible.

You could try making the example yourself to see a little more about what I'm trying to say. Use some brighter colors if you need it.

Again, I appreciate the help.

It does help - a bit - to see the problem. not much, because I don't know how to fix it in Alice. The problem is when you join the two cones, you get two bottom surfaces and thus, if each is 50% opaque, the combination becomes completely opaque and you will see the combined surface at every angle except edge on.

If you use a dual cone without that surface (dual cone_obj), the whole object has the set opacity at any angle - but I don't know how do that in Alice.

The one in the picture and the attached file was done in Anim8or - but unfortunately I got the origin way outside the dual cone. (If anyone wants to fix it - see following post - I've attached the .obj file.) The .ase file for it is also attached in case you want to import multiple versions and try to combine them - if you import them to another parent - say a sphere - and then get them positioned right once - they should stay correctly positioned when you move the parent.

(If you want me to translate this to English - "Sorry - you're out of luck." )

Well, I'm not in school right now, so I can't do much about it, but tomorrow, I'll try to look into it, see what I can tweak. Thanks for the input, Jim.

Now to figure out how to do the continuous laser beam... that's gonna be FUN!

I'm really thinking if you're going to try to do this type of thing, you need to spend a bit time and get at least a little familiar with one of the free 3D graphics programs. The attached is from Anim8or - which I find quite easy to use - but there are other options as I've noted in earlier posts. (Nearly all will also need Biturn to convert from .obj to .ase format - but for simple things like this, that's pretty error free.)

In Anim8or, all you have to do is select the cylinder object from the default screen, click on it to set the parameters you want, make sure it's still selected (I'd also use the position>move to center option) and export it. Try .obj first - if you don't get good results, try .3ds. Both very occasionally give problems -if so, just start over with slightly different parameters.) Then convert it to .ase, use the "import as texture" method you discovered earlier and then edit transparency, color, position, size, etc. in Alice.

I attached one pair of .obj and .ase cylinder files (the cylinder is fairly big physically) to show what you can do. This cylinder has a nice aspect ratio - but it still has end caps - so if you wanted a longer, transparent beam, you'd run into the same trouble as with the cones. In Anim8or (or the others), you have lots of options - taper and bends as well as end caps, for example.

Have fun!
