sinf and and libm on msc

23 June 2014 - 05:24 AM

after compiling 

float x = sinf(y);//y is a float result is the same if i use std::sin

The output dissasembly for msvc is: 

00B61018  push        esi  
00B61019  call        __libm_sse2_sin_precise (0B6192Ah)  
00B6101E  cvtsd2ss    xmm0,xmm0  
00B61022  movss       dword ptr [ebp-38h],xmm0  

Well I'm using floats and it is calling double precision sin(). Compiling the same code with gcc calls "..libm_sincosf". 

Why MS aren't calling single precision equivalents? How can i fix this?

Visual Studio 2013 Solution Exporer h/cpp pairing

11 May 2014 - 03:32 PM

Hi guys!

I'm searching for an add-in that will pair the cpp/h files within the same Filter 'Folder' in the solution explorer.

 

Something like this:

 

-My Filer Blah

---SomeFileName1.cpp

---SomeFilename1.h

---SomeFileName2.cpp

---SomeFilename2.h

 

To become something like this

 

-My Filer Blah

+++SomeFileName1(h/cpp)

+++SomeFileName2(h/cpp)


Is DXGI_FORMAT_R16G16B16_FLOAT missing!?

10 April 2014 - 12:56 PM

In order to create a input layout that represent a vertex element of type half3 we need DXGI_FORMAT_R16G16B16_X (in D3D11_INPUT_ELEMENT_DESC) but there isn't such element in DXGI_FORMAT enumeration.

 

Am I missing something?
