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
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 (or the G_BeginECont
command) and the G_EndE command.
Command:
Points*
Lines*
Polygon*
Triangles*
Line_Strip*
Triangle_Strip*
Triangle_Fan*
Handles primitive as point
Handles primitive as independent line
Interpolation of the joint and broken line pattern is not supported.
Handles primitive as polygon
Handles primitive as independent triangle
Handles primitive as line strip
Handles primitive as triangle strip
Handles primitive as triangle fan
Usable combinations of GMDR0 mode setting and primitives are as follows:
