Hello,
I try to this include file to explode the following object.
But at the time the explosion shall begin the object is invisible.
Does anyone know if there is any restriction to use this include file?
And can anyone give me a solution how I can solve the problem?
If you need more information please write.
Thank you,
Reinhard

Looking at the macro you'd need to assign your object to the identifier
called 'explode_object' before including the #include file. I don't know if
you do that elsewhere in your scene, but, if this is the problem you should
see a warning in the message stream and to fix it you can just add the line:
#declare explode_object = object {DyingstarObject}
before the #include.
Most of the really obvious problems like the camera not pointing in the
right direction, there being no light in the scene etc. you should be able
to test by adding the line
object {DyingstarObject}
to your scene instead of the include file. If you still can't see the object
then it's a problem caused by something other than the include file.
Another possibility that springs to mind is that something is placing itself
between the camera and the visible objects in the scene. For example, if the
camera is very close to the exploding object or inside it and a fragment
happens to shield the camera at the start of the explosion.

Meanwhile I found the problem: because the DyingstarObject object is a
moving object I have to add translate to the explode_object.
An other question I have: Can I manipulate the form of the particles?
In my animation they are looking strange for the exploding earth.
With particle_res I can manipulate the numbers of particles, can I? But
is there an #declare with which I can manipulate the form of them?
thank you,
Reinhard

The help file that comes with the #include file indicates that you can
specify the shape of the individual particles created by the Object Exploder
using the 'particle_object' identifier.

What kind of shape would you use to explode a planet, in my case the earth?

You're likely to need a lot of them over quite a number of frames if you're
animating it, so you'll probably be wanting something that renders very
quickly. That more or less rules out Isosurfaces. Though, if you're doing a
still frame rather than an animation, then you might want to throw in a
couple of extra isosurfaces close to the camera.
One option would be a craggy shaped mesh object which would render quite
quickly.
I've not tried it, but I would think it might also be worth trying just the
union of a cube and a sphere with a very rough pigment and a very rough (but
different) normal. If the sphere radius is somewhere between half the side
length and half the diagonal length of the cube you should get an outline
that is not too evidently spherical (particularly from a distance or if the
bits are moving quite fast). I'd recommend starting with a crackle pattern
for the normal and an agate pattern for the pigment using a range of browns
in the color_map, and see how that works.
Once you've got something in the general direction of what you're trying to
get you could post an image on povray.binaries.images, describing what you
find wrong with it. It can also be productive to provide a link to an image
out on the Internet if there's one that has features you'd like to emulate.
Regards,
Chris B.

Oh, I do not have the Mars image for the image_map. Can you provide it
to me, or is it confidential? :) Could it be? I am from Austria, so I do
not know...

First one I could find on Google
http://planetpixelemporium.com/mars.html
You can get the lower resolution ones for free also the Moray site has
all the solar system planets zipped in the download section.

Very nice but a couple of points. Should not the Earth be rotating the
other way? And is that the Earth that you blew up? :)

You are right, but that is artistic freedom. ;-)
Yes that is the earth that I blew up.

I have an other question:
Does any one know the source code of the explode.inc?
What I want to do is to simulate a gun shoot to a glass window. As you
know the glass shall fragment to a direction, e.g. the shoot comes from
+x direction the glass fragments to -x as a main direction.
Can anyone help me to modify the include file so that I can use an extra
variable like particle_maindirection=-x and the particles are fragments
in this direction?
Thank you,
Reinhard

Reinhard, I don't think there is a binary so there will be no source
code. Just the include files Explode.inc and ExplodeG.inc. Reading the
html file it looks like the variable "exp_location" is what you want
to use. I've never used the include file so have no experience of it.
Quote:
This specifies the vector location of the explosion, and determines
the direction in which the particles will move after the explosion,
eg. making this the same as the object_centre will explode the
particles outwards in all directions, while placing this below the
object will explode the particles upwards. By default this is located
at the origin.

You are right, there are no binaries. And the variable exp_location
works perfect. I set it .30 units to the right and the explosion gos to
the left.
Thank you Stephen,
