GET STROKE 3
CALL SEQUENCE
PGTSK3 (N, VIEWI, NP, PXA, PYA, PZA)
INPUT PARAMETERS
INTEGER N
OUTPUT PARAMETERS
INTEGER VIEWI
INTEGER NP
REAL PXA(N), PYA(N), PZA(N)
ARGUMENTS
- N
- Length of vector to be returned.
- VIEWI
- View index.
- NP
- Number of event points.
- PXA(N), PYA(N), PZA(N)
- Points in WC.
PHIGS STATE
(PHOP, WSOP, *, *).
EFFECT
Reads a 3D STROKE event. The STROKE logical input value is read in the
current event report in the PHIGS state list. It is composed of
points in WC and of the view index used to convert these points from NPC to WC
when the event is placed in the queue. The stroke point list size must have at
least the input buffer size given by the N parameter
Example:
C Event stroke
INTEGER N,VIEWI,NP
REQL PXA(10),PYA(10),PZA(10)
......
N = 10
call PGTSK3(N,VIEWI,NP,PXA,PYA,PZA)
......
ERRORS
- 3
Ignoring function, function requires state (PHOP, WSOP,*,*)
- 259
- Ignoring function, the input device class of the current input report does
not match the class
