xna - Invisible geometry in DX11 -
after struggling many hours understand , compensate microsoft's deprecation of d3dx in windows 8, i've run problem can't shake off.
the first time started program, became immortal because of access violation. after having restarted computer , recompiling , running same code, doesn't crash, cube should seeing isn't there.
i'm getting warning "object declared on heap may not aligned 16". afaik research, occurs because of xna math. so, after finding this discussion litteraly tried being suggested. except xmfloat4x4 solution worked, cube still invisible. here's part of code think relevant:

the key issue here using xmmatrix requires 16-byte alignment class member heap allocated, new on x86 (32-bit) provides 8-byte alignment default.
this xmfloat4x4, xmloadfloat4x4, , xmstorefloat4x4 exist resolve.
xmmatrix vm = xmmatrixidentity(); xmmatrix pm = xmmatrixperspectivefovlh(xm_pidiv4, 800.0f / 600.0f, 0.01f, 100.0f); xmstorefloat4x4( &viewmatrix_, xmmatrixtranspose(vm) ); xmstoreflaot4x4( &projmatrix_, xmmatrixtranspose(pm) ); xmfloat4x4 viewmatrix_; xmfloat4x4 projmatrix_; that or can switch coding in x64 (64-bit) native has 16-byte alignment default , can use xmmatrix or xmvector class member without worry alignment in cases.
this addressed on msdn in directxmath programming guide. see getting started, type usage guidelines
you should take @ simplemath wrapper in directx tool kit. types handle load/store behavior c++ "magic":
#include <simplemath.h> xmmatrix vm = xmmatrixidentity(); xmmatrix pm = xmmatrixperspectivefovlh(xm_pidiv4, 800.0f / 600.0f, 0.01f, 100.0f); viewmatrix_ = xmmatrixtranspose(vm); projmatrix_ = xmmatrixtranspose(pm); directx::simplemath::matrix viewmatrix_; directx::simplemath::matrix projmatrix_; if haven't seen these yet, sure read:
- where directx sdk?
- living without d3dx
- directx sdk tools catalog
- directx sdk samples catalog
- directx sdks of age
- direct3d win32 game visual studio template
edit windows desktop directx development, should use visual studio 2013 community edition if aren't using vs 2013 professional+. includes vs graphics debugger vs 2013 express windows desktop not.
