I'm a jerk.  And sometimes I'm purposefully a jerk.  The reason is that poking at others assumptions and being annoying is actually quite effective at getting them to re-example their own believes...assuming they have the ability to do so.

Look at the complexity of the average single-threaded game loop for something of moderate complexity and get back to me on how single threaded is easier.

AMD has been pretty good about sharing.  It might have been their plan in the first place.  The old it's better to ask forgiveness than permission thing (if you want to make progress).

I'm was only talking about imperative style multithreading.   Functional style is certainly very easy but like running code magically on the GPU instead of the CPU..it is a very poor fit for current to foreseeable future on consumer grade hardware (for games).

Ya'll are missing my point.  All that fancy stuff means you're doing it the hard way.
10  Discussions / Miscellaneous Topics / Re: A rant on OpenGL's future on: 2014-08-14 13:45:51
On multithreading C++ and Java are pretty much the same.  Either you do a simple design and it's easier than single threaded OR you don't and your life sucks.  On multi-gpus...that sort like the apple dev thing of metal or opengl.

The trend among game players has be place less everything else and more on GPUs.  Desktop of course.  More bang for you're buck.

Multiple GPUs for people that play games is probably pretty common and will like become more common .

That's why I hedged my comment.  Note my version above is broken..I yanked out the abs..see the rotated version and it should be clear.

EDIT: And I should note that the clamped version can be made very reasonable for bulking processing by formulating with min/max assuming the language generates max/max opcodes.

Newbies ignore this.  Do whatever works and move on.

Q: How often do you compare exactly two things for intersections?
A: Statistically never.

Ignoring that: this method performs 3-5 comparisons prior to completion and they (should be) statistically random between true/false (given the above...if they are not you're missing information you should be exploiting) with a minimum dependency chain of 7.  Alternate methods will binary subdivide the problem.  After the first comparison 50% of cases will be decided, 50% of the remaining for the second.  A well chosen ordering can cause the comparisons to be not uniformly random (again on average)...so statistically the result will either true or false depending on construction.

As an example (last code snippet):

public boolean intersects(Circle c)
{
  float px = c.x - ref.x; //center.x - delta.x;
 float r  = c.radius;
 
  if (px > r)  return false;

  float py = c.y - ref.y; //center.y - delta.y;

  if (py > r)  return false;
  if (px <= 0) return true;
  if (py <= 0) return true;
 
  px *= px;
  py *= py;
 
  return px+py <= r*r;
}


Symmetry is your friend.

Aside:  that's overkill on comparisons (clamp).

Oh and I meant to mention another announcement which is SPIR (LLVM) seems to be going forward for OpenCL...there's some overlap here so some of these efforts might be merged. https://www.khronos.org/news/press/khronos-releases-spir-2.0-provisional-specification

Making a samples repo would probably make alot of sense.  For instance in the 'combo-box' example widget picture is showing selection between some BRDFs.  A physically based BRDF playground example would probably make a fair number of people try it out

Life (scientifically) is the result of a bunch of a bunch of atoms randomly being placed together after a massive explosion. That alone should be enough.
Let me guess.  Physics isn't one of your strong points.

There is no reason to debate over free will when we will never have the answer to it...
Free will is and probably always will be unknowable. 

Let me make a statement: "Free will is very unlikely to actually exist, but I choose to believe it does."  Think about it for a moment if it doesn't strike you.

Roquen's interview is inspiring. It's similar to mine in many ways, in the sense of existence. Is this a weekly, monthly or annual magazine?
The most inspired part is somebody else did it for me.

I don't understand any of your responses.  It sounds like you're now agreeing that "all possibilities exist at once" is not possible.  On time being a real spatial dimension you talk about the time-space model but for time to be a real spatial dimension means that at the lowest level things must be able to move in both directions across all of that space.  There's no reason to suppose that is so.  You give an example of probabilistic behavior...you can find many of these, but they don't mean anything.  probabilistic behavior is easy to explain...we don't have all the state information and the observed thing is made up of many smaller things.  Even if we came up with an approaching ideal model and that model contained probabilistic behavior...it still would mean much much.  We'd have a accurate predictive model based on what's observable.
