vDSP on iPod 3G, ARM11

Posted in Uncategorized with tags , , , , , , on July 26, 2010 by bersaelor

Thanks to the generous creator of Bowmaster, I now have an iPod Touch 3G at my disposal to test the hardware for one week.

Here I’m gonna start to compare the interleaved-array fillrate using sequential loops vs. the performance of vectorized operations with vDSP. I did this for my iPod 2G in another post.

For comparison against other 3D Engines, I wanted to publish my frames per second and triangles per second results.
I just want to be sure I didn’t miss any important trick I could have used to speed everything up.

Rejoyce: 1.5 will have ambient music

Posted in Uncategorized with tags , , , , on July 4, 2010 by bersaelor

Recently I saw the WWDC presentation on the Accelerate-framework Apple provides for the iPhone.

Now I thought to myself: “My, one very big part of my 3D-Engines code is dedicated to putting 3D geometry information into interleaved arrays, maybe I could speed that up?”
