G_Begin
Command
Reserved
This is the extended
G_Begin
command.
When using the following functions, this command must be executed instead of
G_Begin
.
•
Mode register(MDR1S/MDR1B/MDR1TL/MDR2S/MDR2TL/GMDR1E/GMDR2E)
•
Log output of device coordinates
G_VertexLOG/G_VertexNopLOG
•
Polygon with Z or texture
The
G_BeginE
command sets types of primitive for geometry processing and drawing. Vertex
setting/drawing using the above extended function is performed using the
G_Vertex*
command.
The
G_Vertex*
command must be set between the
G_BeginE
command and the
G_EndE
command.
Only
G_Vertex/G_VertexLOG/G_VertexNopLOG
or
SetColorRegister(XY only vertex)
or
OverLapZofft
can placed between
G_BeginE
and
G_EndE
.
Command:
Points*
Handles primitive as point
Lines*
Handles primitive as independent line
Interpolation of the joint and broken line pattern is not supported.
Polygon*
Handles primitive as polygon
Triangles*
Handles primitive as independent triangle
Line_Strip*
Handles primitive as line strip
Triangle_Strip*
Handles primitive as triangle strip
Triangle_Fan*
Handles primitive as triangle fan
Usable combinations of GMDR0 mode setting and primitives are as follows:
Unclipped primitives (nclip*)
(ST,Z,C)
Point
Line
Triangle
Polygon
(0,0,0)

*1: Shading is not assured.
*2: In case of drawing polygon with Z,ST=1, the algorithm is approximate calculation. The
triangle algorithm is more accurate.
