EZ_Begin(3) EZWGL Functions EZ_Begin(3)NAME
EZ_Begin, EZ_End - delimit the vertices of a primitive
SYNOPSIS
#include <EZ.h>
void EZ_Begin(int mode)
void EZ_End(void)ARGUMENTS
mode Specify the primitive that will be created from vertices between
EZ_Begin and the paring EZ_End. mode is one of EZ_LINES, EZ_LINE_STRIP,
EZ_LINE_LOOP, EZ_TRIANGLES, EZ_TRIANGLE_STRIP, EZ_TRIANGLE_FAN,
EZ_QUADS, EZ_QUAD_STRIP, EZ_POLYGON and EZ_POINTS.
DESCRIPTION
The EZ_Begin and EZ_End pair delimit vertices that define a primitive
or a list of primitives. mode determines the interpretation of subse‐
quent vertices. The interpretation of mode is described below.
EZ_LINES Treats each pair of vertices as a separate line segment.
EZ_LINE_STRIP Subsequent vertices defines a polyline.
EZ_LINE_LOOP Subsequent vertices defines a closed polyline.
EZ_TRIANGLES Treats each triplet of vertices as a separate triangle.
EZ_TRIANGLE_STRIP Subsequent vertices defines a triangular strip.
The first 3 vertices defines the first triangle; vertices 3,2,4
defines the second triangle; vertices 3,4,5 defines the third trian‐
gle ...
EZ_TRIANGLE_FAN Subsequent verticse defines a group of triangles.
All of them share the first vertex. Thus, vertices 1,2,3 defines the
first triangle; vertices 1,2,4 defines the second triangle ...
EZ_QUADS Treats every group of four vertices as a separate quadri‐
lateral.
EZ_QUAD_STRIP Subsequent verticse defines a group of quadrilater‐
als. Vertices 1,2,4,3 defines the first one; vertices 3,4,6,5
defines the second one ...
EZ_POLYGON Subsequent vertices defines a polygon.
EZ_POINTS Treats subsequent vertices as individual points.
EZ_Begin/EZ_End pair cannot be nested. The only commands allowed inside
a EZ_Begin/EZ_End pair are: EZ_Vertex, EZ_Color, EZ_Index, EZ_Normal,
EZ_Material, EZ_Light, EZ_CallList.
