There are a few things you need before starting to make a quadrilateral in Photoshop. First, you’ll need a rectangle that is at least 4x4 pixels in size. Next, you’ll need to create a layer on top of the rectangle. This layer will be used to hold the quadrilateral’s vertices. Finally, you’ll need to create a new layer and name it “quad.” Finally, use the following commands to create the four vertices of the quadrilateral: Command: VERTEX(0 0 0, 0 255 255); Command: VERTEX(1 1 1, -5 5); Command: VERTEX(2 2 2, -10 10); Command: VERTEX(3 3 3, 5 10);
