8. GL naming conventions

• Function names begin with gl or glut

• Data types usually begin with GL:

  
      GLboolean...1 bit
      GLsizei.....2 bits
      GLbyte......8 bits
      GLubyte.....8 bits unsigned
      GLchar......8 bits
      GLshort....16 bits 
      GLushort...16 bits unsigned
      GLint......32 bits
      GLuint.....32 bits unsigned
      GLenum.....32 bits
      GLfloat....32 bits
      GLdouble...64 bits
      GLint64....64 bits
  
  

• Constants start with GL_. e.g. GL_TRIANGLES
