OpenGL Naming

GL function names follow a standardized scheme

When there's only one possible form of arguments:

When arguments can take multiple forms:

e.g. the Color function has the forms:

• glColor3f - 3 floating point arguments
• glColor3i - 3 integer arguments
• glColor3ub - 3 unsigned byte arguments
• glColor3fv - 1 argument, a vector of 3 floating point numbers
• etc.

Constants are defined for certain function arguments

Constant names are all in capital letters, in the form:

e.g. possible arguments for glBegin() are:

• GL_POINTS
• GL_LINES
• GL_LINE_LOOP
• GL_TRIANGLES
• GL_TRIANGLE_STRIP
• etc.
