Now just to figure out how to flip vertices 180 degrees around to make a roof.[/QUOTE]

I think you just need to set y/z (what ever is the up vector) to -y/-z

Shit.

Got back to work on my 3d opencl renderer

Objects are now asynchronously added during the runtime of the program - memory is allocated for the size of all the triangles currently in any object being rendered to the scene, this is all copied onto the graphics card, and then the current engine memory pointer is updated (mutex lock to prevent awful things from happening) to the new memory. The old memory can then be freed asynchronously as well, after this

This essentially means that adding new objects to the scene won't cause any delay whatsoever to the running of the program (though may take several frames for the actual memory itself to be allocated, and the object to be drawn to the screen). Also, because the memory new memory has to be allocated while the old memory is still present, this means that you are wasting a load of memory while transferring the two. I can't think of a way around this though at the moment

Currently though, I am very lazily getting around to implement a system to pass textures to the program. Unfortunately opencl is not a fan of being passed arrays of Image2ds, though perhaps i can pass a 3d texture that is actually the 2d textures on different layers - each layer being an object ID (or a variation of that).

I'll get around to it at some point

[QUOTE=Chris220;35808279]Is stuff like this more often done with realtime beat detection, or are the timings hardcoded? I'd assume the latter because the demo only has to work well with that one song, and it cuts out the fact that beat detection is rarely perfect.[/QUOTE]

yeah i'm not the hugest fan of beat detection/fft. i find manual timing provides more rewarding results, and it takes as much time as one would spend making analysis results usable.

[QUOTE=Funley;35808862]Well, i generate the vertices like this:

verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X, position.Y + 1, -position.Z),
                new Vector3(0, 1, 0),
                new Vector2((currentwall * 2) / imagesInTexture, 1)));
            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X, position.Y + 1, -position.Z - 1),
                new Vector3(0, 1, 0),
                new Vector2((currentwall * 2) / imagesInTexture, 0)));
            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X + 1, position.Y + 1, -position.Z),
                new Vector3(0, 1, 0),
                new Vector2((currentwall * 2 + 1) / imagesInTexture, 1)));

            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X, position.Y + 1, -position.Z - 1),
                new Vector3(0, 1, 0),
                new Vector2((currentwall * 2) / imagesInTexture, 0)));
            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X + 1, position.Y + 1, -position.Z - 1),
                new Vector3(0, 1, 0),
                new Vector2((currentwall * 2 + 1) / imagesInTexture, 0)));
            verticesList.Add(new VertexPositionNormalTexture(new Vector3(position.X + 1, position.Y + 1, -position.Z),
                new Vector3(0, 1, 0),
                new Vector2((currentwall * 2 + 1) / imagesInTexture, 1)));

That generates one floor piece. How exactly can i change how each vertice is oriented?[/QUOTE]

Instead of position.Y + 1, try -(position.Y + 1). If Z is up then do that to z.

I'm jealous, I've had to pretty much halt my OpenCL work in order to deal with the end-of-course ramp-up in my other classes / final projects / procrastination because I was working on my photon mapper so much this quarter.

Depending on how complex your scenes are (last time you showed it it looked like maybe a cube-room and a couple of spheres) you shouldn't have too much to worry about in scene allocation. If you aren't already just make sure you're storing the minimum amount of information necessary, like how a sphere only needs 4 floats to represent it completely.

My scenes are currently ~200 bytes including my material definitions and I have the same number of primitives as you do, it shouldn't be terribly expensive.

beat detection is worthless in the first place

there is no magical universal tuning for frequency averages that will detect beats on every single last song provided, so there's no point in it for using it for the reasons you'd expect (to do less work)

the problem with beat detection is that to use it for anything useful, you'd need a set of algorithms that could detect beats across multiple different genres and play styles

that's one problem, but you also have the general "how do you define what a beat is?" issue

in the end, beat detection is best used in controlled, tuned cases. but if you're going to do that, you might as well just manually sync whatever your work is to whatever music you're using, because you'll end up actually doing more work tuning your beat detection for more than one song

I ended up accidentally creating the most attractive project of the science fair had to take part in (the robot arm) and got myself a backache and a sore throat trying to explain what the thing did to kids and their parents. The arm wouldn't work 50% of the times, yet the kids were still incredibly amused when I switched to manual control and grabbed pieces of LEGO and let them go in their hands.
The guys showing their projects in the stands next to mine came to me complaining that I were getting all the attention and I replied that I never asked for it and would gladly switch places :v:

The kinds fucking about with the arm were incredibly unnerving though.

placing a block in a random lane whenever there is an impulse in the spectrum is hardly decent.

The highlight of today was when a guy who's a quite important authority in the field of mathematics here in Italy (some of his articles are even in my maths schoolbook) came up to my stand and noticed that I was reading GEB, this book:

Decided to make a gravity simulator thing so I made the moon and the earth and gave them proper distances, radii, masses and everything. Ran the simulation and there were two dots on the screen just sitting there.

After checking my forces, distances and everything a couple of times it hit me.
It takes 28 days for the moon to orbit the earth...

I believe that every language has a gap it can fill so it's never wasted effort (unless it's unusably slow or something)

For 95% of music, it gets it close enough to right that the user doesn't notice it. It doesn't have to be perfect.

I don't like nullsquared's attitude towards more or less everything (and have disagreed with him in this thread countless times), but by not trying to be 100% perfect and meet every single edge case, he's managed to nearly complete a game which seems to be fun and is about to launch on the android marketplace.

Perhaps I should clarify what my point is - just because something is technically hard, or a project doesn't demonstrate capability, doesn't mean it isn't fun to play or successful

[ryandaniels]

So I woke up early this morning, thinking I was giving myself PLENTY of time to redo my term project for one of my classes properly. I was very, very wrong.

My favorite part was where, with an hour and half before I had to go present it at school, as I was staring at the screen trying desperately to determine why I was getting a stack overflow, I decided to check how much of my grade this was worth.

[B][I]30%[/I][/B]

It wouldn't have been so bad if the code was getting exponentially shittier and more unusable because of what turned out to be a very bad design. But I couldn't abandon it or I wouldn't have a hope of finishing it.

and then, with only 30 minutes to go, I discovered the final bug, meticulously stepped through the execution to check for any other errors, and ran several tests. It was working!!! I slapped on some documentation and ran out the door as fast as my frail, malnourished, nerdy body could handle.

100% woooooo

[Topgamer7]

[QUOTE=COBRAa;35806867]What is the reason they made it descend?[/QUOTE]

They made the stack grow downwards, because the heap grows from the other end upwards. In order to not have them overflow all the fucking time, this is how they did it. Hence you get a stack overflow. Or at least that's how they explained it to me in school ;).
