The _glAccum statement operates on the accumulation buffer.
Syntax
- _glAccum GLenum op, GLfloat value
Parameters
- OpenGL is using its own set of variable types to describe its command parameters.
- Use the following table to find 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's 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.
