Fixed Point Maths or GLfloat?

Hi all,

I’am new in OpenGL and OpenGL ES.

Should I use GLfloat in OpenGL ES? Will it slow down the program?..

In fact, I search this topic in the internet. There are many papers say that Fixed Point Maths should be implemented in moblie devices. Is it true?

Thanks for your help.

If you can, yes, try to use fixed point math.
At this point, most mobile devices based on ARM do not have a core that directly supports floating point math. Also, at least in the case of Vincent, the floating point layer is a wrapper around the fixed point kernel, so using fixed point reduces the level of indirection and hence increases the performance.
