It been awhile, I lost the internet a few month ago.
Really my Wi-Wi connection to my computer died.
Trying to get a new one was an adventure in itself.

Now to all the things (most of the things) I had questions about.

Has any one use the windows Pov Editor to make audio Data samples for Audacity?
I have and it was fun!

I also wanted to know if there are any people who use my height field programs
from my web site.(http://leroyw.byethost15.com/)

I've use them and POV to make a road on Mars. Then I animated a road trip.

While doing so I came upon a thing about natural splines. In order to make a
complete oval path I had to use 8 values from the end of the spline in front of
the basic spline & 8 values from the start of the spline at the end.
I wonder if any one has come across this before?

A word about animation: I did something that save my a lot of time rendering.
I render the Road animation, it took 6 hours and it was just you flying around
the track. Then I rendered a Car only with Apha on.(it took 45 min. to render.)
Then I combine the two using images maps on in front of the other and render the
final animation. (render tine 35 min.)

I was wondering how many people use this technique?
And what other other techniques you find useful?

It's nice to be back.
I know I forgot some other question that where important at one time or another

Thanks for any replies!
Have Fun!

Not here, but would be interesting to see the annimation.

What didn't work with fewer?

I'm not a great user of POV-Ray's splines, but you do sometimes have to 
overlap on loops to get continuity or completeness. Never heard of 
anyone needing 8 additional values of both ends though. More wouldn't 
hurt I guess, so long as you are still picking off the loop values you 
need from the middle of the spline.

I'm not an animation guy, but cool trick.

Glad you're back.

I couldn't get the spline output values to match exactly. I settle on 8 because
it gave a fractional match to 5 decimal places.
6 was good for 4 places, I tested up to 10 places(my spline was big 35 elements)

 I don't either, but I did use the dickens out of splines for this project.
After I made the road height field using splines, I made an image map with the
road pavement and the 3 lines on the road, They all use different splines. Oh I
almost forgot the path around the track and the sound track. Their the reason I
needed the spline extended. I was getting a jump when played as a loop.

Not _yet_, as I have so many other things eating up time, and IIRC, I have to
switch over to Windows....
But I think you've solved a problem I wanted to address a while back.

Truly, you are a madman.
I would like to borrow even half your energy and focus.


I hope you document some of what you learned and how to edit sound...

Do you know if there's a way to read in MP3 in any meaningful way?


Glad to have you back.   Connectivity issues are a real challenge sometimes.

That wakens old memories from before my POV days... but no, I am not 
using/making audios anymore.

I am ashamed to confess: It is /still/ on my todo list (taking dust in a 
corner of course)...

I would like to see that! Is it visible somewhere?

Really I'm lazy. But when I start something I can't let go.

 I wish. To much of it is scatter on multi drives and stuck in my brain.

 I haven't really got into MP3 code. From my understanding it is lossy like jpg.
I've played mostly with Wave and Midi and Mpeg(the very old version ).

First I like to thank you all for you replies.

I put an update version of MarsCars, MarsCarsII on youtube

https://youtu.be/oxD8bSPVMng

I also made a play list but I really don't know how they work

it's Leroy's POV-ray gun.

There is 4 videos on it.

Finally I wanted to tell the reason I wanted to know if anyone use my height
field programs. While I use them to make the height field & data used in my
videos, I thought of a lot more functions I could add. For one thing Zoom, And
better contour lines to map algorythem. And while I'm at it put the road
function in somewhere. Maybe even a river function. It would be a total rewrite.
I don't know if it would be worth the trouble.

Thanks again! and Have fun!

It probably would be an interesting exercise to do so. :-)

Do you know WorldMachine? http://www.world-machine.com/index.php

It has now also a 'Road' and a 'River' feature. The free version is 
limited to a 513x513 output but with some creativity and the help of 
other HF generators this is not a very big issue.

After a brief look at WorldMachine. It'll be better to forget about making maps,
and concentrate on updating the map placer program. To tell the truth I haven't
looked at many other HF generators for a long time.

Have Fun!
