[Plib-users] Using callback

[Peter G. P. <pe...@cs...>]

Hi

I can see in the code that

virtual ssgCallback getCallback ( int cb_type ) ;
virtual void setCallback ( int cb_type, ssgCallback cb ) ;

is only included for backward compatibility.

Is callback deprecated completely, or should I use

ssgTravCallback getTravCallback ( int cb_type )
void setTravCallback ( int cb_type, ssgTravCallback cb )

instead? If so what should the traversal bitmask in cb be?

Yours
Peter

[Plib-users] Changing the pitch/volume of non-looping sounds

[Christos D. <dim...@id...>]

I have used plib successfully to load and play 8-bit sounds. I have
found that looped samples, as in the examples given at the site, have
no problem handling envelopes. However, when dealing with one-shot
samples, which I play using playSound(), volume/pitch changes using
envelopes do not seem to work. I create a new envelope once, and I
load the sample once. This is the code that I use:

    crashSample[i] = new slSample(filename[i], sched);
    crashVolEnv[i] = new slEnvelope(1, SL_SAMPLE_ONE_SHOT);

Now... the question is.. where do I do AddSampleEnvelope()?
I tried doing it immediately after loading the sample:

    sched->addSampleEnvelope(skidSample[i], 0, 0, crashVolEnv[i],
SL_VOLUME_ENVELOPE);
    crashVolEnv[i]->setStep(0, 0.0, 0.0);

Then, in order to play the sample at the appropriate volume I just do:

    sched->playSample(crashSample[i]);
    crashVolEnv[i]->setStep(0, 0.0, appropriate_volume);

... and finish with

sched->update();

This did not work at all. The sound was always played at the same
volume. So I thought maybe the sample envelope gets lost after the
sample finishes playing. Thus I added the envelope everytime the
sample was played, but to no avail:

    sched->playSample(crashSample[i]);
    sched->addSampleEnvelope(skidSample[i], 0, 0, crashVolEnv[i],
SL_VOLUME_ENVELOPE);
    crashVolEnv[i]->setStep(0, 0.0, appropriate_volume);

...

    sched->update();


What am I doing wrong? Can you help?

Hello

As far as i know all of the examples SSG examples use lighting, have a look
at tux_example. It initializes a light for that. One thing you may have to
keep in mind is that you also have to setup the surface material of what you
are trying to light.

Hi

I have now had some very good experiences with SSG (thanks!). One thing I
still cannot fully get to work is light. I have found the ssgLight class,
but I'm not really sure how to use it. I do know about reflection, diffuse
light and all that, but it is how it should be set, initialize and other
stuff in SSG. Any docs/examples on that?

Mat,

I tried making the framework but had no luck.  I also used the 
ConvertMake utility to help me, but I could not put the plib libraries 
into the framework.  Could someone help me build the framework with 
some specific directions?

Thanks,

It is even  no requirement for pui  itself. I am using it  with my own
code, glwin,  only a  few changes have  been necessary.  Basically one
would  need   a  simple  registry  mechanism   for  windowing  toolkit
callbacks. I still dream to find some time to propose a patch for pui.

Re: [Plib-users] SDL and SSG

[Ben W. <za...@ec...>]

Hey,

If you are getting nothing but a black screen then perhaps you should remove
plib from the equation. Make sure you have a window open and gl initialized
correctly, display a gl triangle and then incorperate ssg back in. I used
them together a long time ago and I don't recall having issues once my gl
context was initialized.

Normals are used by OpenGL for lighting - you can get much better
shading with per-vertex normals.

[Eric L. <la...@uf...>]

The documentation for ssgVtxArray is at:

http://plib.sourceforge.net/ssg/ssgLeaf.html

If that isn't enough, you'll probably have to look at the source.

When creating a ssgVtxTable, is it then required that the number of

I so, I find it a little odd as I thought that the normals was related to

Re: [Plib-users] plib framework on OS X

[mat t. p. <pr...@tt...>]

The framework is the method that I used for a project I did.  Its kinda 
screwy though because even after you build the framework you'll need to 
add all of the libs (from /usr/libs/something etc) to the project.

To make a framework just make a framework project and add all of the 
headers to it.  From there you'll need to fiddle around with the 
sources and such because I can't remember how to do it exactly.  
Frameworks are just collections of code, you may only need to compile 
the headers.  There is some tool out there that can make things easier 
for the Mac world but I can't remember the name of it.  Search through 
the archives for OS X stuff and you should see it mentioned somewhere.  
Good Luck.

Re: [Plib-users] Can't compile pui examples

[Daniel T K. <dan...@dy...>]

You are right.

Yesterday, I went back through the mailing list archives and found what 
would work:

env CC="cc -Xcpluscomm" CXX=CC ./configure

the 'CC' is the compiler I should have been using.   my brain was obvious 
not engaged.

There are still several problems with the configure scripts on an SGI/Irix 
operating system.  I have glut & opengl properly installed and the 
configure script would not find them.

Only insane people try to read and understand Makefiles which are 
autogenerated by automake/autoconf. :*) I have no idea whats wrong with 
the above line. I dont even understand what it means.

"make check" is in almost all cases optional, so if it does not work, 
just skip it. If you got "make" and "make install" working, you should 
have all you want. Sorry, I didnt try the examples on Linux, only on 
Windows, so cannot comment much on it. Plib itself compiles without any 
problem on my Linux.
