CHAPTER 5: Scripting with JavaScript Working with the perspective grid 53

//Set left plane as the active plane

app.activeDocument.setPerspectiveActivePlane(PerspectiveGridPlaneType.LEFTPLANE);

//Set right plane as the active plane

app.activeDocument.setPerspectiveActivePlane(PerspectiveGridPlaneType.RIGHTPLANE);

//Set floor plane as the active plane

app.activeDocument.setPerspectiveActivePlane(PerspectiveGridPlaneType.FLOORPLANE);

Draw on a perspective grid

When the Perspective Grid is on, drawing methods allow you to draw or operate on objects in perspective.

This script creates a new document, shows a two-point perspective grid, and draws art objects on the left

plane:

//Create a new document

var mydoc = app.documents.add();

//Select the default two-point perspective preset

mydoc.selectPerspectivePreset("[2P-Normal View]");

//Display the perspective grid defined in the document

mydoc.showPerspectiveGrid();

//Check if active plane is set to left; if not, set it to left

if (mydoc.getPerspectiveActivePlane() != PerspectiveGridPlaneType.LEFTPLANE)

{

mydoc.setPerspectiveActivePlane(PerspectiveGridPlaneType.LEFTPLANE);

}

//Draw rectangle in perspective, then resize to 200% and move

var myrect = mydoc.pathItems.rectangle(30, -30, 30, 30, false);

myrect.resize(200, 200, true, false, false, false, 100, Transformation.TOPLEFT);

myrect.translate (-420, 480);

//Draw ellipse in perspective

var myellipse = mydoc.pathItems.ellipse(60, -60, 30, 30, false, true);

//Draw rounded rectangle in perspective

var myrrect = mydoc.pathItems.roundedRectangle(90, -90, 30, 30, 10, 10, false);

//Draw polygon in perspective

var mypoly = mydoc.pathItems.polygon(-105, 105, 15, 7, false);

//Draw star in perspective

var mystar = mydoc.pathItems.star(-135, 135, 15, 10, 6, false);

//Draw path in perspective

var newPath = mydoc.pathItems.add();

var lineList = new Array(4);

lineList[0] = new Array(0,0);

lineList[1] = new Array(60,0);

lineList[2] = new Array(30,45);

lineList[3] = new Array(90,110);

newPath.setEntirePath(lineList);
