| Function | LtStatus
| ||||||
| Synopsis |
Reverse the orientation of a list of primitives.
| ||||||
| Location | ligeops | ||||||
| Parameters |
| ||||||
| Return Value |
A status value.
| ||||||
| Description | LiPrimitiveReferenceReverse calls LiPrimitiveReverse for each primitive on the linked list it is passed. The results from each of these calls are merged to provide the final return value. | ||||||
| Example |
LtPoint positions[4] ;
LtProp props[1] ;
LtData values[1] ;
LtPrim poly1, poly2, prim_array[2] ;
LtStatus status = LI_STATUS_OK ;
LtPref plist ;
LiPointInitialise( positions[ 0 ],
0.5, 0.5, 0.0 ) ;
LiPointInitialise( positions[ 1 ],
-0.5, 0.5, 0.0 ) ;
LiPointInitialise( positions[ 2 ],
-0.5, -0.5, 0.0 ) ;
LiPointInitialise( positions[ 3 ],
0.5, -0.5, 0.0 ) ;
props[ 0 ] = LI_PROP_VERT_WORLD ;
LiDataSetFloatPtr( values, positions ) ;
poly1 = LiPrimitiveCreatePolygon( (LtNat32)4,
(LtNat32)1,
props, values ) ;
prim_array[0] = poly1 ;
LiPointInitialise( positions[ 0 ],
0.5, 0.5, 1.0 ) ;
LiPointInitialise( positions[ 1 ],
-0.5, 0.5, 1.0 ) ;
LiPointInitialise( positions[ 2 ],
-0.5, -0.5, 1.0 ) ;
LiPointInitialise( positions[ 3 ],
0.5, -0.5, 1.0 ) ;
LiDataSetFloatPtr( values, positions ) ;
poly2 = LiPrimitiveCreatePolygon( (LtNat32)4,
(LtNat32)1,
props, values ) ;
prim_array[1] = poly2 ;
plist = LiPrimitiveListCreate( 2, prim_array );
status = LiPrimitiveReferenceReverse( plist );
