The _glAccum statement operates on the accumulation buffer.


Syntax

_glAccum GLenum op, GLfloat value


Parameters

  • OpenGL is using its own set of variable types with its command parameters.
  • Use the following table for conversion to the respective QB64 Variable Types.
  OpenGL     =>     C/C++        =>       QB64
================================================
GLenum => unsigned int => _UNSIGNED LONG GLboolean => unsigned char => _UNSIGNED _BYTE GLbitfield => unsigned int => _UNSIGNED LONG GLbyte => signed char => _BYTE GLshort => short => INTEGER GLint => int => LONG GLsizei => int => LONG GLubyte => unsigned char => _UNSIGNED _BYTE GLushort => unsigned short => _UNSIGNED INTEGER GLuint => unsigned int => _UNSIGNED LONG GLfloat => float => SINGLE GLclampf => float => SINGLE GLdouble => double => DOUBLE GLclampd => double => DOUBLE GLvoid => void => no parameters used


Description

  • OpenGL documentation is available in several places, so we won't reproduce it here for another time.
  • The full description for this command can be found at Microsoft Docs and is also valid for QB64 usage.
