That's a good point. I'm still clock maxed soldering together the obsolete semiconductors of the synthesizer of the fantastic years of yore. By the way, hitting i 4 z (filename) enter 1 esc esc ten thousand times is still faster than menu traverse select aim select open, but a single key reload / refresh of the .txt file would be even better.
Are you referring to "math save_as_txt" for saving text tables from script?Quote:

I think it's just import_space. It is important to know that when you do that it gets converted from short int space to unit space, meaning it is reduced in size to fit inside of a cube from -1 to +1. It can be scaled from there, of course but that puts it into the same magnitude as the math generators, more or less.
Are you saying "I think of LaserBoy space as import space."? My present understanding is that LaserBoy space is the A and B register space.Quote:

LaserBoy_space is the 3D frame_set viewer, the running application with a frame_set loaded in it that you see on the screen. That's in short integer.
Here are some new frames I did using LaserBoy's drawing utilities, over a background bitmap.
These will be added to in.ild that comes with the LB distribution.

Just curious why your and Greg's screenshots of LB are so bright red and mine are so dim red. I'm using Greenshot for screen captures.
If you go into the [Tab] menu, option 4, option 1 you can make your vectors any thickness in pixels. If you go to option 0 (zero) of the same menu you can set a number of square pixels for which to save bitmap files of your frame_set. Option o to output a file offers 6 bmp as an option. It saves to the bmp folder inside of LaserBoy. You have to open the bitmap in an image editor and save it as something else, like jpg, gif or png in order to post it as a visible image on this forum. When LaserBoy saves a bitmap it makes it the lowest bit per pixel possible to support the number of unique colors. Anything less than 24 bits per pixel is best converted to a gif (a pallet image)
Thanks, that is a good tip to know. I'll stick with Greenshot for Win10 screenshots, its far easier. & versatile.Quote:

You can make a directory of as many bitmaps as there are frames all in one shot. That's how I made the videos.
I see, that then is useful when using bitmaps to create a video stream.Quote:

Fixed some bugs.

I want to thank lasermaster1977 for all of his attention to this. He's been working with it quite a bit and he has helped me root out some issues. He's also proofread a lot of the documentation. I must say he has a lot of patience. Most people would just throw their hands up and run away. He asks some really good questions.
I wholeheartedly agree with you. He is a great guy to work with and very knowledgeable!Quote:

Because of some examples from lasermaster1977, the whole mess of constructors for all of the line functions was re-written and it actually works now.
There was an issue of a real number (double) being an integer or not. Turns out, if there is some real math involved, an expression that should result in a value of 50 is actually over by a number that is in the 10^ -15 magnitude.
Did some major code cleanup. Fixed an ancient bug.

Let me know if you find any weird behavior, other than the usual.

This one doesn't have any new recognizable features, but the menus are a bit cleaned up. Now all of the settings that make LB do its thing are two clicks away.
First [Tab]
Then pick a sub menu
There's all the settings in that sub menu.
This works from just about anywhere in the menu system.
I also did tons of code cleanup. It used to be over 95 thousand lines of code. Now it's only about 79 thousand.
And for the first time ever, parts of it are written in C++17 threads!
So, if you have a processor with a lot of cores, you might notice a speed increase.
I don't think there is anything new in the txt folder, but it's there for completeness.
As always, please let me know if your computer explodes.

This one turned out nice.
I just ordered a computer with dual intel Xeon E5-2683v4 16 core CPUs (32 cores) and 256GB DDR4 EEC RAM, 1.92TB SSD and a really nice NVidia 4GB GDDR5 video card with 4 output ports.
That should run Ubuntu rather well!
Yeah, but does it come with a modem? That's the real question. :-)Quote:

New development version. Just source code and example txt files.
Plus instructions for building from source in MacOS and Windows.
This has all the newest features in a version that has no multithreaded code.
I haven't done anything with the txt examples or the doc files. When I get all that updated, I'm going to do an official full public release.
The settings menus are all now in a new [Tab] menu sub system. So from just about any place in the LB menus, you can change settings with [Tab] {category} {setting}.
This version can read 3 channel waves like those made in OsciStudio.
Feedback much apriciated.
Cool. I'll give it a spin pretty soon.
How's your new toy?
It's pretty neat.
Not exactly what I expected though. It turns out that on this dual CPU mobo each CPU has its own 128GB RAM. I'm not sure how that works but I guess I'll figure it out.
It's super quite which is nice but it puts out a steady amount of heat.
The single thread speed is really not much faster than my previous 8 core AMD system.
But if I run make with the argument -j32, this tells make to run in as many as 32 cores.
What takes about 2 min 40 sec to build LB in a single core can be done in about 34 seconds.
What's really impressive is the video card. WOW. This thing can decode and render streaming video of any size to a 4K screen at full speed with no artifacts at all.
I imagine video editing on this system will be wonderful.
Dell PowerEdge?

(Last one! Who's going to get it?)
This thing takes forever to POST and get through the BIOS. I guess it has a lot to test, like 2 CPUs with 16 cores each and 2 banks of 128GB ram.
https://images.nvidia.com/content/qu..._NV_FNL_HR.pdf
I guess the video card has 8GB. I thought it was a measly 4GB.

In this version the only change is the addition of two new operators in LaserBoy Liquid Math.
clip and _clip
These allow you to define a 3D rectangular solid region of space and eliminate all vectors outside of that region.
The single version clip uses the same region for all frames in a frame_set.
The animated version _clip uses a region that can move, change size and proportion through the frames in a frame_set.
I also did extensive work on the file LaserBoy_Liquid_Math.txt in the doc folder.

For those of you who might want to totally geek out on math:
https://www.3blue1brown.com/
This guy gives it to you fast, in a way that makes sense (at least in the moment) and very chill.
Some of it is about 3D space (and shit).
I certainly agree...his methodology for conveying math concepts, principles and actions are extremely good...nuff said.Quote:

Then I find that the documentation is way too confusing, so I simplify the code and the way it works in the running application.
I have been really busy lately trying to get it all together for another public release and I have found so many ways to make it all better.
It might be a while, but this is all coming together to be something really special.
I have made so many changes that all of my tutorial videos are totally out of whack.
No. There is no new f@*king mouse support!
But there will be much better docs and a lot of new features and easier to read menus.
I've made so many improvements that I thought it was time to share another development version of the source code.

Oops!
The version I posted previously does not compile in Clang in MacOS.
This one should be fine.

James.
I just put together a limited number of new LaserBoy Correction Amp kits!
The kit is a printed circuit board and all of the parts to make it whole, plus a DB25F ribbon cable (ILDA port).
$40 USD
You must supply the sound device and any kind of box you might want to put it in.
The USB C-Media CM6206 sound chip is 8 channels at 16-bit 48KHz and works well with this Correction Amp. Look for "USB SND8".
The kit comes with a DC/DC converter that is designed to run off of USB +5VDC power.
It is also possible to use an internal 6 or 8 channel sound card. The DC/DC converter can be left off the board and the amp can be powered directly with +12VDC and -12VDC from the computer's power supply.
This will allow you to build a LaserBoy DAC that can play multichannel wave files like those made in LaserBoy and some other laser apps and ADAT shows transcribed to wave files. There is also a live streaming dll for Windows apps that support it.
If you give me your address, I can let you know how much it will cost to ship it to you.
I will also provide whatever tech support you need to make it work.

By the way... The writing is on the wall.
Windows 11 is coming.
As if Windows 10 isn't a complete disaster.
It's time to learn Linux y'all!
I mean you're only like 30 years late to the party, but that's ok!
It's way stupid simple these days.
Get a nice USB drive of any size 64GB or more.
Copy the Knoppix iso onto it.
Boot from it.
Enjoy!
Learn.
Install Ubuntu or Debian on a real hard drive.
Live happily ever after.
Already got Win 11 on my laptop- the Start button is now a little more to the right and the furniture has been rearranged a bit.Quote:

I cleaned up everything. If you already have an installation folder of LaserBoy, I would recommend renaming it as old and unzipping this in its place. Then move your files from the old folder(s) to this new one.
For Windows users:
The zip no longer contains a 32-bit version.
LaserBoy.exe is now a 64-bit application.
Please let me know if you find any problems or have questions.

Yet another new version!

Fixed up a lot of menu stuff.
The alt menu (t) idea is now more consistent through the four menus that use it.
Menu c for coloring a frame or the frame_set now has parameters for cycling
through the palette or the 1530 pure hues through the frames,
starting each next frame at a progressively shifted index in the array of colors.
Let me know if there are any issues or questions.
Update:
09_05_2021
Fixed all the new color cycling stuff in menu c.
