content: I have electronic engineering in my blood, so I do a lot of thinking.The answer to life, the universe, and everything, is 42.. Only joking.Our universe started from nothing and became something.The only way to create something from nothing is to break it in two.For example:There is no high tide without low tide.There is no night without day.There is no good luck without bad luck (otherwise luck would have no meaning).There is no happiness without sadness.

content: @Peter,You may not be aware that this forum has a problem with Spammers who register, make a single mostly irrelevant post then come back a few days later to edit in their spam links. Fortunately our excellent team of moderators (and admins) are very much on top of this and remove the spam very quickly.Assuming you aren't a spammer, staying more on topic (i.e. electronics related or at the very least, hard science or engineering related) will help keep the mods off your back. Also you may wish to consider introducing yourself:https://www.eevblog.com/forum/chat/new-member-please-introduce-yourself/--I am not a moderator here, no do I play one on TV!

Thank you for alerting us all to, and most of all,providingthis contrast.

content: Quote from: Ian.M on May 23, 2022, 11:11:17 amActually the fast spam busting on here is mainly due to the quality of membership who do care about the quality of forum they use and will report stuff that looks suspicious having become experts at spotting it. Rarely do I not do something about a user reported for spamming or being a potential spammer as most people reporting it are spot on and often reports contain good background information that helps limit the research we have to do to validate the claim that "uh, I think it is spam"

content: Quote from: Simon on May 23, 2022, 06:01:32 pmYes. e.g. if I report something as 'Spam', I've already checked the links for you, or if I report 'Spammer' they've made multiple spam link posts.However, our contribution to eliminating spam couldn't work without the mod team's quick response to reports. e.g. another forum I sometimes use is notorious for their slow-acting moderators, who seem to be limited to a few hours per weekday during office hours for their HQ. As a result spam posted after close of business on a Friday will still be there for the next 60 hours or so, and longer if the weekend is adjacent to a public holiday!

content: Quote from: Peter Taylor on May 22, 2022, 02:57:09 pmLife is a sine wave. It has ups and downs.The period of a human sine wave is roughly 80 yrs I'd say, a typical life expectancy in a modern western country nowadays. It may get longer in the future as we improve healthcare, society, etc. Maybe even indefinite if we can reverse aging?But, what about the sine wave of the universe? Does this mean the expansion may stop at point, that it will start to contract again?But that's the rate of change.. you get volume by integration. Does that imply there is also (going to be) a universe with negative volume?I digress.For me that is a rhetorical question. I agree with your statements. We as humans tend to converge to a psychological neutral state, no matter the experiences we've had in the past. Some things in daily life may remind of us our past.. some memories that are important to hold on to, other memories important to work through, but that ultimately makes the high and low tides we are all faced with.

content: Life is too complex for trite and simple answers. However a lot of people seem to gravitate toward the trite and simple; a look at social media will confirm.Human life is no more special than any other animal life. The humans seem hell-bent on over populating our only planet to the point of eventually making it uninhabitable for our species. Over population is seldom if ever mentioned because that isn’t the answer people want.The universe is probably infinite beyond human comprehension.

"Luck" is a load of utter nonsense, made up by people who refuse to thank GOD for blessing them, and blame/thank "luck" instead for failure or success."There is no happiness without sadness." So tell that to people who are ALWAYS happy and rarely get sad (and they DO exist)

content: Quote from: bd139 on May 23, 2022, 06:15:39 pmUses Tait-Bryan ("Euler") angles, with rotation around X and Y axis defined by mouse dragging. Friends don't let friends do that.(There is a reason my fingers always first type it as Taint-Bryan.)First, use versors (unit quaternions) or bivectors –– pick your model: the math is the same.Second, use the trackball rotation scheme. Within the ball, when the user drags the mouse, draw an imaginary line from the starting point to the mouse cursor. Rotate that (in 2D) by 90° counterclockwise (by replacing (dx, dy) with (dy, -dx)), and you have the 3D rotation axis. (It's always planar to the display, z=0, but that's ok.) Normalize that to unit length by scaling the three components by the length of the vector, i.e. square root of the sum of squared components. The length of the original line corresponds to the rotation angle around that axis, with the radius of the imaginary trackball corresponding to 90°, and diameter to 180°.Outside the ball, the rotation axis is the Z axis. Use atan2() with respect to the center of the imaginary trackball to obtain the angles for the start and end point since the rotation angle is the difference between the two angles –– or basic 2D vector algebra to turn them into unit vectors; their dot product is the cosine of that angle, and the 2D analog of cross product is the sine of the angle.A quaternion describing rotation around an unit axis vector by some angle has the cosine of half that angle as the real part, and the unit vector components multiplied by sine of half that angle as the other three components. So that's trivial to construct for both the above cases.Save the original orientation (quaternion or bivector), and combine with the temporary new one via multiplication (Hamilton product). That's just a single line (or four lines, if you pretty-format the code).For drawing, scale the quaternion to unit length (by dividing each component by the square root of the sum of the squares of the original components), and then convert to a normal 3Drotation matrix. That's eleven lines of code if pretty-formatted.No need to copy someone elses GL Matrix JavaScript library, no need to use unintuitive rotation controls.Why do people think that the easiest way is the crappiest way everyone else is doing?Euler and Tait-Bryan angles should be banned, dammit: they're like a spanner that occasionally turns to soft rubber, or a dildo that occasionally grows latching spikes.If you do something, do it better. The world is already drowning in crap, no need to add tothat.
