Justin,

I have your Taotimer on my IPhone and I think that it is a good product. I was wondering if you would consider an upgrade to allow the timer to do 20 repetitions instead of just 10. In addition to the Xing yi, Tai Chi, & Kung fu that I practice, I also do 3 different forms of Chi gong. 2 of these chi gong forms have more than 10 positions. Your timer is wonderful for the other form (as well as other things) but not quite sufficient for these 2 forms.

Thanks,
Robert

Hey justin,

Sorry to spam your blog but have you tried to do render to a depth texture via FBO on 3GS ?

Shot me an email if you want to discuss it a bit.

The fat binary capability is great.

Although, I’m using malloc to allocate my matrices and vectors, I wonder if we have to do the same SSE/SSE2 fftw_free to get everything aligned properly ?

Can find what is the alignment requirement for NEON.

See instructions here: http://monkeystylegames.com/?p=82 on how to make a armv6 and an armv7 build within a universal binary.

If you’re trying to switch between different implementations at runtime, then yes there is going to be overheard – you’ll have to measure it to find out how much.

Hello monkey,

I’m trying to take advantage of SIMD and integrate it in my app but I cannot figure out an elegant way to ship a version including normal instruction and SIMD for the 3GS.

All I can think of would be to have a function pointer, but I’m afraid the stack frame overhead will void the gain of SIMD.

What do you think ?

There is also a section of the book: “Unique chips” (altough it looks like a lot of infos are from http://infocenter.arm.com/):

Nice work! I plan to make a very similar game Can I ask what model pipeline you are using?

Really cool entries as I am diving into Neon Assembly in order to optimize my 3D engine ( http://www.youtube.com/watch?v=PgHnqERODpk )

I hope to see a lot of other posts in the future !
