Lurking as a guest long enough
« on: June 11, 2018, 06:58:50 AM »
szStr   db   "Hello MASM32 world", 0

I would like to offer you all a drink but this is impossible
through email, until your 3D printer can make a whisky.

The Game Development sub forum is my favored corner.

As you all know the D3DX 11 utility library is deprecated thus NO

     D3DX11CreateShaderResourceViewFromFile

This is how to do it with pure dx11 and gdiplus in MASM.
Gdiplus because it can handel .jpg, .png and .bmp

        ;;  Note swSomeTexture is a UNICODE string i.e. LPCWSTR
        ;;  Set third parm TRUE to let dx11 Auto Generate (dx11 decides how many) MipLevels
    invoke  CreateShaderResourceViewFromFile, g_pd3dDevice, addr swSomeTexture, true, addr g_pSomeShaderResourceView

Welcome to the forum!   :t

Looks like you're all set to do some 3D game programming. Congrats!

I have been lurking as a member for quite some time.  :P
I'm not always the sharpest knife in the drawer, but I have my moments.  :P

Thank zedd151 you for the welcome.
Yes I hear you were lurking, even
when you had no PC. Good to see
you're back.

Thank you Siekmanski for the welcome.
I have learnt a lot from your posted.
Thanks for sharing your work.

Thank you felipe for the welcome.
Worked long enough on the intro, it
was time to post.

I think you did not put it clearly.
D3DX11CreateShaderResourceViewFromFile is in the d3d11.lib and I have been using it in my examples. Sure, Microsoft says it is deprecated for Windows 8 and above (this does not mean it does not work) and can not be used with Windows Store applications (what an inconvenience for the guys here).

AW thanks for the welcome as well as the corrections.
I'll try to be better at explanations.

Also AW a special thanks for making your DMath available.

daydreamer thanks for the welcome

O.K. Take two

As you all know the D3DX 11 utility library is alive and well.

IF someone would like to know how to load a dxll ShaderResourceView as a cube map
i.e. a BOX (not a 3D TEXTURE) in MASM32 using the D3DX 11 utility library, this is how.

Note that each 1 of the 6 sides of the cube/box surface can have image staging form a
high res (.MostDetailedMip = 0) to low res (.MipLevels = 10 ). Here we are using 6, 2D
textures assembled as a cube map array housed in a .dds (Direct Draw Surface) file

The 6 images may or may not have more than one MipLevel and are stored as:-

                      (+Y)                 
              (-X)  (+Z)  (+X) (-Z)
                      (-Y)

Code: [Select]
;; You will need these two structures.

D3DX11_IMAGE_INFO STRUCT   16
  dWidth            DWORD  ?
  dHeight           DWORD  ?
  dDepth            DWORD  ?

Hi Caché GB,

Can you post the exe?
Maybe also the full source code, so we can learn from it and share our knowledge?

Hi Siekmanski.
 
I duet you could learn from me. It is I who have learnt so much
from you and many other great members here on the forum.

To post full sauce would mean to post coding techniques
studied from everyone here in an effort to gain knowledge.

So give me time to put some Full demos together for posting that would
not be removed be the CIA (copyright infringement administration)

Do you have any idea just how difficult it is to post from a smartphone? Especially when the autocorrect changes every other word you want to type?  :P

I'm still not back full-swing yet. Doing a lot of crap cleaning on Windows 10 Home Ed. I'm almost there though,
and will be coding and making real contributions to the forum soon. See you in the Game Dev. subforum.   :biggrin:
