The reason you don't want to use sqr is for speed, right? The first thing that comes to my mind: in your code, you use the value of z to calculate the blue level, and this level is an integer value between 0 and 255. Also, the value of z is supposed to vary between 0 and 1, it cannot go out of range...

MilkShape3D can export to B3D.

There is also a plugin for Blender that allows to export to B3D (just check the version, not all versions of Blender are supported, I think)

Dodicat, glBegin...glEnd are commands deprecated from almost every version of OpenGL, so it's better not to teach OpenGL in that way

In the later version it's called openb3d.bi

I also remind that, for the dos version, the batch file maksymbr.bat has to be launched, and then the main runtime library has to be compiled again before distributing the compiled version

I wonder if it's possible to create a ring laser crystal , instead of a beam laser crystal. No, because "ring laser crystal" means nothing, it's a term that makes no sense. When the two parallel lasers come together , they might diffuse?? If they are parallel, they cannot come together. I...

This is not possible, because if the base has already the laser emitter. If you put the mirror over the emitter, it would block the laser beam, that would be unable to reach the mirror on the top.

First of all, there is no such a thing like a telescopic crystal. Also, trapping light inside a crystal would have a serious issue: true, you can use refraction and reflection to make a photon "bounce" around, following a path inside the crystal, but such a path would either be open, or cl...

I'm out of paper.... I've filled a 500 page notebook with manipulation formulas over the last two weeks.. 1000 pages.. Got to buy another 500 page notebook... What are you trying to do? Are you trying to say, like Fermat, that you have a great formula but not enough space to write it? My question i...

My library OpenB3D (formerly MiniB3D) should do what you need

Listen, Albert: if you want a formula to square numbers, use this:



It works. Now, please, stop posting non-working pieces of code.

The subject has already been discussed many times, here, for example: https://www.freebasic.net/forum/viewtopic.php?f=4&t=22664

I hope this helps.

I don't know about the coroutines. It looks like a library+header would be enough to add. Frankly, it feels like too much for me to promise to do it. What's needed in the compiler? Auto-injecting yields()? A precompiled library+header might be enough, although I suggest to add the library to the FB...
