Opengl version 4.3 on my computer.
Is it the asm you have compiled ?

The Binary work
On wich system have compiled them ?
Is there a way to upgrade opengl ?
It isn't in c++ I want a result,visual studio is enough to do that but in ASM.

Yves,
you still haven't answered my question. Does my program in http://masm32.com/board/index.php?topic=8880.msg96843#msg96843 work on Windows 10? There is just black screen? Or blue rotating sphere and two shapes inside the sphere?

OK,it's work

Found ,"ouf!",many thanks for all help.
it was the "aspect" who wasn't converted to real in resize.

Code Select Expand


resize PROC FRAME largeur:GLsizei,hauteur: GLsizei
Local aspect:GLfloat,raspect:REAL8

invoke glViewport,0, 0, largeur, hauteur
;----- Knock down by Math,let's it done by C: aspect,(GLfloat) width / height
cvtsi2ss xmm0, largeur ;DWORD PTR ;convert dword to real4
cvtsi2ss xmm1,  hauteur ;DWORD PTR
divss xmm0, xmm1
movss aspect, xmm0
cvtss2sd xmm0,aspect ; DWORD PTR convert real8
movsd raspect,xmm0

;invoke MathLabA ;aspect,(GLfloat) width / height;
invoke glMatrixMode,GL_PROJECTION
invoke glLoadIdentity
invoke gluPerspective,REEL8(45.0), raspect,REEL8(3.0),REEL8(7.0 ) ;<<<<<<<<<<<<<<< most important raspect REAL8
invoke glMatrixMode,GL_MODELVIEW
ret
resize endp

movq xmm3,constd7
movq xmm2,constd1
cvtsi2sd xmm1,w
cvtsi2sd xmm0,h
divsd xmm1,xmm0
movq xmm0,constd45
invoke gluPerspectivevariable aspect (used only once) it is better not used at all
variables declared as float GLfloat latitude, longitude, latinc, longinc
are used where double is required
    glRotated(-latitude, 1.0, 0.0, 0.0);
    glRotated(longitude, 0.0, 0.0, 1.0);although before calling the procedure polarView it is indicated that the arguments are doublevoid polarView(GLdouble radius, GLdouble twist, GLdouble latitude, GLdouble longitude) masm64 did not understand this (no explicit float to double conversion), but C++ understood

see if these two instructions are any use to you.

        cvtsd2si    ; Convert Scalar Double-Precision Floating-Point Value to Doubleword Integer
        cvtsi2sd    ; Convert Doubleword Integer to Scalar Double-Precision Floating-Point Value

Hi, hutch--!
I know about instructions cvtsd2si and cvtsi2sd. I wrote this post after analyzing the program openglw10_64 which at first displayed a dark screen, but x64dbg showed me where are the errors
