Transaprency once again.
Sword part of object taken from svn server of KolibriOS. Heart I made many years ago on piece of paper. Joint of both, some optimiztion on sword, separate every chunk - in app win3ds. Front of 'heart' chunk has 'only' reflective component. I think I gives more reliable transparent look... I want perform some real time shadows - but not yet... Roses texture taken somewhere from net...
Its sse4 32 bit app.
edit:
I change 'sword' part of object to my own, unfortunatelly bit biger. I attach only sources.
edit2:
I add bump effect, bilinear filtered like texture...

isn't kolibriOS the hostile fork of menuetOS 32 which made the menuet authors go closed source for menuetOS 64?

Hi!
Thanks for your reply..

I dont understand how this related to my example.. My app is open source, no depend to Menuet. If you ask about sword - if there is right conflict, I would make my own.. Just give a sign. Example is for Windows XP+ (I tested only win7, I don't have sse4 machine with XP), but making Kolibri/Menuet ports is not big problem.
Best regards.

I test run it on Windows 10, the graphics look cool.

At first I thought Sword was a different length than Dword, Qword... but finally after seeing the graphics, only then I know it was the sharp object. Razz

Starting with the fasmg distribution, I made the following changes to compile this fine example in fasmg:

First, delete folder "\mater_dolorosa2\include".

Extending the default 32-bit PE beyond Pentium 6:
\fasmg\packages\x86\include\format\format.inc, line 100
Code:
        format?.include '../cpu/x64.inc'    
Change include paths - beginning and end:
\mater_dolorosa2\mater_dolorosa.asm
Code:
include 'win32a.inc'
include 'cpu\ext\sse4.2.inc'    
Code:
section '.idata' import data readable writeable
    library kernel32,'KERNEL32',\
        user32,'USER32',\
        gdi32,'GDI32',\
\;        winmm,'WINMM',\; unused
        comdlg32,'COMDLG32'
    include 'api\kernel32.inc'
    include 'api\user32.inc'
    include 'api\gdi32.inc'
    include 'api\comdlg32.inc'

Thanks for your replies and work!! Very Happy
To be precise - I apply Phongs illumination model (ambient + diffuse * cos x + specular * cos^n x) as follows: Front of object has specular component, heart - only, sword - specular + diffuse + ambient; surfaces that are more deep, more far from observer have diffuse + ambient part of equation.

works well under WINE, perhaps your final transparency would be depth-independent transparency Cool

This is not really needed if you include SSE4, as it includes SSE2 as well - and for 32-bit code p6.inc+ext/sse2.inc provides more or less the same as including x64.inc.

And I had to do one more thing here, replace lines like:
Code:
tex_2:          times 4 dd 2.0    
with:
Code:
tex_2:          dd 4 dup 2.0

Nice. I had an error once [can't even recall what it was] and imagined a cut-off in 32-bit support; but in hind-sight that doesn't make sense. Maybe, I've been thinking about it from an invalid perspective.

Yes - its depth-independent transparency. I tried with kind of sorted transparency in other project. I sort every pixel by its z position and achive kind of G-buffer, but with only sorted Z coord. But in this example is depth independent.
BTW Morgan McGuire wrote some articles this topic related - to read on https://casual-effects.com
