The
G_Vertex
command sets vertex parameters and processes and draws the geometry of the
primitive specified by the
G_Begin*
command. Note the following when using this command:
•
Required parameters depend on the setting of the
GMDR0
register. Proper values must be set as
the mode values of the
MDR0
to
MDR4
registers to be finally reflected at drawing. That is, when “Z”
comparison is made (ZC bit of MDR1 or MDR2 = 1), the Z bit of the GMDR0 register must be set to
1. When Gouraud shading is performed (SM bit of MDR2 = 1), the C bit of the GMDR0 register must
be set to 1. When texture mapping is performed (TT bits of MDR2 = 10), the ST bit of the GMDR0
register must be set to 1.
•
When the Z bit of the GMDR0 register is 0, input “Z” (Zoc) is treated as “0”.
•
Use values normalized to 0 and 1 as texture coordinates (S, T).
•
When the color RGB is floating-point format, use values normalized to 0 and 1 as the 8-bit color
value. For the packed RGB, use the 8-bit color value directly.
•
The GMDR1 register is valid only for line drawing; it is ignored in primitives other than line.
•
The GMDR2 register matters only when a triangle (excluding a polygon) is drawn. At primitives other
than triangle, set “0”.
•
The use of both G_BeginE to G_EndE and G_VertexLOG/NopLOG is not assured.
•
G_VertexNopLOG, except for the primitive as point is not assured.
•
A vertex data is processed at every time. For example, the MB86R02 'Jade-D' draws interpolation of
bold line joint, edging line, shadows at every vertices.
•
Alpha parameter can be provided only packed ARGB format.
