![]() ![]() rect(x,y,w,h) Ī more advanced drawing option is to use beginShape() and endShape() to specify the vertices of a custom polygon: beginShape() Īnd you can build more complex shapes by grouping a set of drawing functions together, even perhaps organizing them into a class. One of the very first things you learn when programming with Processing is how to draw "primitive" shapes to the screen: rectangles, ellipses, lines, triangles, and more. A cylinder has a constant circular cross-section, two circular faces and one curved. 5) delete the face that you selected by selecting it then pressing delete. 4) click one of the faces enter // defines the surface that cuts the object. 3) type: surface enter // this says we want to slice the object with a surface. A square is a 2D shape, whereas, a cube is a 3D shape. Three-dimensional (3D) shapes: 3D shapes have a length, a width, and a height. Select File -> Examples in the Processing IDE, then select Topics -> Create Shapes.) 1) type: slice enter // calls the slice command. In this section, we will discuss the two major types of shapes: Two-dimensional (2D): 2D shapes, as the name suggests, have only two of these measurements, i.e., length and breadth. (The source code for this tutorial are in the Processing Examples. (x,y) location for the shape as well as its dimensions (width,height).
