Description

Gets view matrix for layer or viewport object.

FUNCTION GetViewMatrix(
				objectHandle                : HANDLE;
				VAR offsetX,offsetY,offsetZ : REAL;
				VAR rotationXAng            : REAL;
				VAR rotationYAng            : REAL;
				VAR rotationZAng            : REAL): BOOLEAN;
def vs.GetViewMatrix(objectHandle):
    return (BOOLEAN, offset, rotationXAng, rotationYAng, rotationZAng)

Parameters

Name Type Description
objectHandle HANDLE
offset REAL
rotationXAng REAL
rotationYAng REAL
rotationZAng REAL

Examples

gViewportInfo [gNumSheets2].View := viewToPopup (GetObjectVariableInt (h, 1007));
OK := GetViewMatrix (h, x, y, z, gViewportInfo [gNumSheets2].RotateX, gViewportInfo [gNumSheets2].RotateY, gViewportInfo [gNumSheets2].RotateZ);

boo := GetViewMatrix	(
						GetLayer(GetObject(RefGridPIOName)),
						VMatrixOffsetPt3D.x,
						VMatrixOffsetPt3D.y,
						VMatrixOffsetPt3D.z,
						VMatrixAngleX,
						VMatrixAngleY,
						VMatrixAngleZ
						);

{ get the rotation of the view if there is one }
currLayer := GetParent(objHand);
WHILE (currLayer <> NIL) & (GetType(currLayer) <> 31) DO currLayer := GetParent(currLayer);
boo := GetViewMatrix(currLayer, offsetX, offsetY, offsetZ, rotXAng, rotYAng, rotZAng);
boo := SetViewMatrix(currLayer, 0, 0, 0, 0, 0, 0);
import vs
