void glVertex3iv(const GLint * v);

void glVertex3fv(const GLfloat * v);

void glVertex4dv(const GLdouble * v);

PARAMETERS¶

v

DESCRIPTION¶

glVertex commands are used within glBegin()/glEnd() pairs to specify point, line, and polygon vertices. The current color, normal, texture coordinates, and fog coordinate are associated with the vertex when glVertex is called.

When only x and y are specified, z defaults to 0 and w defaults to 1. When x, y, and z are specified, w defaults to 1.

NOTES¶

Invoking glVertex outside of a glBegin()/glEnd() pair results in undefined behavior.
