GET STROKE 3

PGTSK3

CALL SEQUENCE

CALL PGTSK3 (N, VIEWI, NP, PXA, PYA, PZA)

INPUT PARAMETERS

INTEGER N

Length of vector to be returned.

OUTPUT PARAMETERS

INTEGER VIEWI

View index.

INTEGER NP

Number of event points.

REAL 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
