Bytes to float...
langauge?
in c and many of its offspring itll look like
EDIT: fixed horrible error!

// one 4 byte arraychar bytearray[4];float f = *((float*)bytearray);// many floatschar byteArray[4 * numFloats];float * floatArray = (float*)byteArray;float f = floatArray[ index ];EDIT: fixed horrible error!

better question: why do you want to?
Either way it's fairly common thing to do..

trying to convert a dang mesh vertexbuffer into vector3's
thanks for your guys help,

At least dealing with the structures at the byte level shouldn't be necessary as long as you're storing regular 32-bit floats in both.

the Mesh.LockVertexBuffer() method returns a byte array. For what I have figured out so far, I have to use the vertexDeclaration of the mesh to walk thru the byte data to determine what's what.
Any easier ideas are most certainly appreciated. But still it would be nice to know how to convert from four bytes to a float.
I'm using c# and I tried:
byte[] ba = {100, 1, 114, 123};
float f = (float)ba;
and it says can't convert.

This may not be the most efficient way, but it sure is easy.
byte[] ba = {250,62,246,66};float f = System.BitConverter.ToSingle(ba,0); // f now equals 123.123F
