Again.  Reasonable thinking in the common case which has nothing to do with the points of this topic.  These suggestions are a non-option.
2  Discussions / General Discussions / Re: Why are people jerks? on: 2014-09-28 17:28:19
All of that is a given.  My point is that it's unacceptable for people to move from being hostile jerks to criminal attacks.  As a society we must condemn criminal attacks even if we disagree, even strongly, with the attacked assuming the attacked is engaged in legal activity.

"Exactly.  The bitch deserved to get raped.  Did you see how she was dressed?  I saw her drink at least one glass of alcohol.  And the way she was dancing?  The cunt deserved it."

Something like that?
We keep saying that, but at the same time we all lock our doors, we have expensive alarm systems, we use anti-virus software, we hire bodyguards, we have anti-cheat software for our games... If you forget to lock your door and your house gets emptied by a robber, it's obviously not your fault, but that doesn't mean that you couldn't have done anything to prevent it. There are lots of things that we shouldn't have to do, but if we don't some people will take advantage of us.

Preventive measures is a different topic.  And frankly virtually all of them only give you an illusion of added security.  Oh and for people having a bad "connect-the-dots" day my rape example is to highlight the "blame the victim" mentality.  We all do that in our heads at times.  And the reason most of us do so is because it subconsciously makes us feel safer for ourselves and people we know.  We wouldn't have done that so bad things wouldn't happen to us.

So sticking with my rape example...what exact meaningful preventive measure can a woman take?  Answer none.  Like murders the vast majority of rapes are by persons known.  Back on the generalized version of the topic of this thread...what preventive measure can you take if your opinion might anger others?  Say nothing?  f**k that...the world sucks enough, imagine how much worse it would be if nobody ever spoke out about anything.

@Cero:  I don't understand anything your saying...are you sure you're in the right thread.

I could care less if Mr. Fish is or isn't an asshole.  It's moot.

Maybe you should clarify whom you're referring to.

... but the reality is it only makes one small aspect of writing games easy.
Absolutely.

An admittedly particularly difficult and expensive or time consuming aspect but it's one less barrier...
If you're going to write something like unity, ue4, etc.  We'll call that 4 years of real time...8 years of opportunity cost time to create the same thing...assuming you're knowledgeable in all the requirements.  Of course in those 4 years the middleware solutions are 4 years further along.

Maybe but they don't have much to do with the topic on hand.
9  Discussions / Miscellaneous Topics / Re: What I did today on: 2014-09-25 10:22:47
That's middleware and libraries for you.  You always should ask yourself why you're not using them if they do the job you need accounting form whatever cost.

singles and doubles only have the same latency numbers for the most basic operations, so divide will differ etc...add,mul,fabs..the super basics are the same.

While I'm complaining about tripe, for me it goes beyond stereotypes.  I like my fictional characters to be understandable in their actions and goals.  On the up side it's cool that the quality of television series has quite improved.
12  Discussions / General Discussions / Re: Why are people jerks? on: 2014-09-24 08:31:46
It's not really games.  It's all popular media.  News has become entertainment and entertainment has been (on average) moving toward the lowest-common-denominator.  Chicken-and-egg problem of perceptions about what sells and market creation by default if you follow me.  Numbers are like 1 in 10 are gay.  The vast majority of gays ya don't know unless they they clue you in.  The vast majority of gays in media are the flaming extravagant kind.  The vast majority of murders are by people known to the victim...not the impression you get from the news, because most murders are boring.  I know very few excellent programmers or scientist that fit the projected mold, etc. etc.

OP: I just turned up a multiply factor and started to see results in line with my expectations, so I think the problem with your code is that it's isn't returning full range.

Gustavson's version from the paper is out of date, at least the last time I looked at the paper, check the code: http://webstaff.itn.liu.se/~stegu/simplexnoise/

Quote
... all the doubles to floats in ... no measurable performance difference
I use singles because doubles don't bring anything to the table.  On intel the time to issue and latency of single and double add/mul are the same so without reading/writing they should be the same.  Who knows embedded devices might take off sometime in the future which don't use intel desktop/mobile CPUs.

Thanks.

A newer version is here: https://github.com/roquendm/JGO-Grabbag/blob/master/src/roquen/pg/noise/SimplexNoise3D.java

Flipping to the more expensive hash removes some defects, but this is intended to be example code not really production ready.  I really need to add a note about the patent to the source.  There's all kinds of choices about hashes depending on use-case.

OP:  I took a quick peek at the output of a single sample and it appears like there's a bug...perhaps the output isn't full range.  Visually it looks like a lightweight blur has been applied.

Quote
Why isn't the OP medal-slapped?! Pointing
My 2011 reference implementation which is twice as fast, equal usable and patent free (assuming you don't flip the switch) has a grand total of zero.  Potentially useful things often don't get bombarded with medals as I'm sure you're aware.  Stefan Gustavson's version from 2005 is likewise patent free and equally usable.  BTW as far as patent's are concerned this one is nice as it only claims an exact formulation.  So this whole patent free thing is much ado about nothing.

Quote
... is only a mere inconvenience for the performance junkies.
But  performance is quite important for this kind of noise.  It needs to be fast enough to not require build-time generation.  If you need build-time generation then you might was well kick it up a notch to a non-realtime noise generator.

Table lookups are not your friend.
20  Game Development / Newbie & Debugging Questions / Re: Get points of rotated rectangle? on: 2014-09-21 13:26:57
Assumptions made:  memory is fast, branches and jumps are fast and FP multiples are slow.  zero for three.  What it's attempted to do is eliminate multiplies by zero and +/-1 by tracking or inspecting if the matrix is in a special case.  Exponentially slower than performing the computation.  You have:

x' = m00x + m01y + m02
y' = m10x + m11y + m12

stage 1:  | t00= m00x | t01=m01y |   t02=m10x |  t3=m11y |
stage 2:  | t11=t01+t02 |  t12=t03+t04 |
stage 3:  | t21=t11+m02 |  t22=t03+m12 |

So if you had a CPU that could issue 4 multiples or 2 adds per clock, this computation takes three cycles to issue (ignoring loading and storing).  Moving that to a more realistic 2 multiples issued per clock then this take 4 cycles to issue. Calling a multiply 5 cycles to complete, then the latency is about 10 cycles (too lazy to think it through).

Reading in the variable that specifies "what special case" from L1 cache to register takes 5 cycles of latency and everything goes massively downhill from there.  So that 4000 line class would be much faster if it were probably less than 200.

Care to elaborate?  Wink
It's written to be reasonable on machines prior to the Pentium 3.  On newer machines than that....it's doing it complete wrong.

WRT: OP's question.  What is it?  As is it only mentions a single rotation.
22  Game Development / Newbie & Debugging Questions / Re: Get points of rotated rectangle? on: 2014-09-20 12:43:34
Notes:  AffineTransform is a pile of junk.  Avoiding a sqrt is fine, but sqrt is only expensive compared to add/mul.  It's faster than division and much faster than trig.  If you care about speed for something then don't use angles.

It's funny how nobody's mentioned he didn't have 100% control of the company.  He could have wanted to say no.  Even if he had controlling interesting, being nagged by other other shareholders would be a big emotional burden.

You could also look at selling to microsoft as dropping a turd on their lawn.  The have to beat the overall opportunity cost that comes with putting down 2.x billion.  Do the math...and don't forget the math has to be all 'net' gains.

Method handles?  No it's link time dispatch code generation.  Simple thing is define a functional interface with the method signature and make a handle...call...win.
27  Discussions / General Discussions / Re: Java 8 Default Methods and Multiple Inheritance on: 2014-09-17 18:15:06
BTW: Method handles....many interesting things here.  More than default methods IMHO.

Generally still too much.  It re-transmits...see above.
30  Game Development / Networking & Multiplayer / Re: Check if UDP message was successfully received? on: 2014-09-16 12:11:53
It's common to want to send unreliable packets.  By the time you get the ACK the information is already dated and you're better off sending new updated info rather than data that will be useless by the time it's received and still need to send the updated data soon.  TCP is great for sending large static data or not needing to worry about xfer (sorta) if time isn't important.
