QuestionNeed fast method to read/convert floats from disk Pin
nadiric19-Sep-06 8:35
nadiric19-Sep-06 8:35 
I'm reading a bunch of raw numerical data (floats representing verticies) from disk in one endian format, and need to convert it to another (flip the bytes around).

Currently I am reading the numbers one by one and bit-shifting them to the correct format, then placing them into their respective places in an array of verticies (float[3]'s).

I am trying to speed up this whole operation, and may be able to do so with a better method/algorithm. The following also may help:

- Each float is 4 bytes and needs a pure reversal of bytes - not bits (bytes 1234 become 4321)

- the floats are contiguous on disk
- I know ahead of time how many floats I will be loading into a given array
- The array will be pre-allocated to hold the right number of verticies
- I must keep (or end up with) the array two-dimensional (array of float[3]'s) for later OpenGL usage

not sure if reading them all in at once, and applying a macro-bit-shift would be faster?

Thanks for any help
