Is there any other free vector library optimized for neon that math-neon? I would like to get advantage of neon in my code, i have lot of objects and i am doing lot of simple vector physics-math, like adding vectors, multiplying, dotting them, those are 3d vectors but if i could make it a lot faster 2d should be ok too, the question is, is it worth using neon? for example lets take 100000 points, i need to calculate their movement, collisions etc. I am currently using my own math, and its based on inline functions, lets say that i would like to use my hypothetical neon library with matrices too, currently i am using glm for that, and its doing fine, but could it be faster? Speed advantage between arm-abi and arm7-abi in ndk is about 30 percent in my case, can neon be faster or maybe my code is translated to neon in compile time?
You can check eigen. It has special code that it is activated when neon instruction support is activated.
