[fasm-help] macros for OpenGL

[Andrey Ch <so...@ma...>]

Hi, fasm-help-request.


In OpenGL there are these variables:

GLenum          equ             dd
GLboolean       equ             db
GLbitfield      equ             dd
GLbyte          equ             db     ;-128..127
GLshort         equ             dw     ;-32768..32767   signed 16-bit
GLint           equ             dd
GLsizei         equ             dd
GLubyte         equ             db
GLushort        equ             dw
GLuint          equ             dd
GLfloat         equ             dd     ;REAL4
GLclampf        equ             dd     ;REAL4  ; float clamped to [0,1]
GLdouble        equ             dq     ;REAL8
GLclampd        equ             dq     ;REAL8  ; double clamped to [0,1]


for example I write this code:
 _glColor3f 0.1f,0.1f,1.0f
 _glVertex2f -0.6f,-0.6f
 _glColor3f 0.1f,1.0f,0.1f
 _glVertex2f 0.6f,-0.6f
 _glColor3f 1.0f,0.1f,0.1f
 _glVertex2f 0.6f,0.6f
 _glColor3f 1.0f,1.0f,1.0f
 _glVertex2f -0.6f,0.6f

after processing the macro I get this code

invoke glColor3f,3DCCCCCDh,3DCCCCCDh,3F800000h
invoke glVertex2f,0BF19999Ah,0BF19999Ah
invoke glColor3f,3DCCCCCDh,3F800000h,3DCCCCCDh
invoke glVertex2f,3F19999Ah,0BF19999Ah
invoke glColor3f,3F800000h,3DCCCCCDh,3DCCCCCDh
invoke glVertex2f,3F19999Ah,3F19999Ah
invoke glColor3f,3F800000h,3F800000h,3F800000h
invoke glVertex2f,0BF19999Ah,3F19999Ah


 glVertex2f
          ^^ f is type GLfloat


That's all.
