VPORT_Z_OFFSET_ENA 5 0x0 Viewport Transform Offset Enable for Z component
|
|
VTX_XY_FMT 8 0x0 Indicates that the incoming X, Y have already been
|
|
multiplied by 1/W0.
|
|
If OFF, the Setup Engine will bultiply the X, Y
|
|
coordinates by 1/W0.,
|
|
VTX_Z_FMT 9 0x0 Indicates that the incoming Z has already been multiplied
|
|
by 1/W0.
|
|
If OFF, the Setup Engine will multiply the Z coordinate
|
|
by 1/W0.
|
|
VTX_W0_FMT 10 0x0 Indicates that the incoming W0 is not 1/W0.
|
|
If ON, the Setup Engine will perform the reciprocal to
|
|
get 1/W0.
|
|
SERIAL_PROC_ENA 11 0x0 If set, x,y,z viewport transform are performed serially
|
|
through a single pipeline instead of in parallel. Used to
|
|
mimic RL300 design.
