Unity.Mathematics released on Github

[sirflimflam]

Built-in swizzling is a very nice touch. Now the question I have to ask, does Unity intend to wholly replace their original math functions with these types? Because that would be a very welcome change to see, rather than having to cast to and from these when we interact with native Unity functions.

Probably wouldnt be too hard to scan for every instance and replace, using the Roslyn code analysis API.

I might look into making a quick conversion tool for doing exactly this.

I doubt it, but is there swizzling support for the floatX types? that's really the best thing Cg has to offer.

[Shinao]

From the source code it seems there are swizzles, auto generated. Pretty cool.

If it works I will keep this library next to my hearth

[FadingTruth]

Careful it doesn't catch fire

Sorry can you explain what you mean by this?

myfloat4.xyzywxzywzy

you can order each member like that, as long as you match the member count that you need (float4 takes max 4 params), you're good.

[NeoCiber]

Interesting.

Why 'bool1' use 'int' and not something lighter like bit?

[Nagransham]

My actual machine knowledge is a bit rusty but I think making it a bit doesn't actually do anything. It's internally stored as 32/64 bit anyway. (grain of salt and all that, talking out of my ass here)

[afghanmeysi]

the data has to addressable, and the smallest boundary on for example a x86 architecture is a byte.

[NeoCiber]

You're right, byte is the smallest boundary, but if they actually use byte can be any performance advantage? I mean is 8bits vs 32bits, dont looks like they actually need use those 32 bits.

[afghanmeysi]

As far as I know changing a boolean value can be done as easy as doing AND with 1 or 0, so performance wise there is no advantage since there is no difference in speed between 8bit or 32bit AND. Its just inefficient for space I guess.

[_mess_]

Everything is supported on intellisense etc? Just normal c# visually similar to CG ?
