For example, if you connect a number to the text of the textpath, NodeBox converts the number into a string so it can be rendered as text. NodeBox automatically converts between types of ports. The background color of a node is the color of its output type. They are the primary visual building blocks of NodeBox. They contain information about curves, lines and points. They are used to specify logical conditions: whether something is enabled or visible, whether elements need to be filtered out or not, etc. Booleans are values that can be either true or false.They are used to specify color information: the fill color of an object, the stroke color of a line, etc. Colors contain red, green and blue values.They are used to specify a place in 2D space: the position of a rectangle, the scale of an object, etc. Points are two-dimensional coordinates in space.They are used wherever we need textual input: the filename of a SVG file, the lookup value for a CSV file or the text in a textpath node. They are used to specify amounts: 10 copies, 50 points, etc. Integer numbers are numbers without a fractional part.They are used to specify dimensions: the width / height of an object, the distance between two points, etc.

Floating-point numbers are numbers with a fractional part.

Port TypesĮach port expects a certain type of values: The values for the width and height ports come from another node. Whenever a port is connected, the port view indicates that the value for this port comes from another node: Ports are displayed both in the port view (vertically) and the network view (horizontally). The input ports are also displayed in the port view: The input and output ports of a node are displayed in the network view. A node takes data in from its inputs, processes it, and sets a value in its output port, ready to be picked up by the next node. Ports represent the inputs and output of a node. Nodes can send data to each other using their ports. You can render a node by double-clicking it. The rendered node is the one that’s displayed in the viewer. We can examine what each worker node is doing by changing the rendered node. This is also a filter node, it filters the colored rectangle node. It takes the output of the color node and changes its rotation.

Finally we create a rotate node and connect it to the color node.

We call it a filter node, since it filters an existing shape. This node takes the output of the rect node and changes its color.

We connect a colorize node to the rect node.

This node is a generator: it generates a new shape. Every step along the way can be changed and animated. They are the basic building blocks of the application.īy connecting nodes together, you create your own assembly line where a new shape goes in and a complex result comes out. In the NodeBox assembly line nodes are the workers. Warszawas assembled at FSO in the early 1950s. After he or she has done their operation, the object is passed on to the next person who does his thing.

Each worker does one thing, and one thing only. Shoes also borrows some animation ideas from Processing and will continue to closely consult Processing's methods as it expands.NodeBox uses a different model from traditional applications such as Photoshop or Illustrator. And Shoes also allows images and gradients to be used for drawing lines and filling in shapes. For example, Shoes has different color methods, including having its own Color objects, though these are very similar to Processing's color methods. Shoes does a few things differently from NodeBox and Processing. I owe a great debt to the creators of these wonderful programs! In turn, NodeBox gets much of its ideas from Processing, a Java-like language for graphics and animation. The artful methods generally come verbatim from NodeBox, a drawing kit for Python.

See the section on Colors for more on how to mix colors. The blue and red methods above are Color objects. One-hundred pixels wide, placed just a few pixels southeast of the window's upper left corner.

That code gives you a blue pie with a red line around it. And the fill command sets the color used to paint inside the lines. You'll need to set up the paintbrush colors first, though.

Many common shapes can be drawn with methods like oval and rect. Each slot is like a canvas, a blank surface which can be covered with an assortment of colored shapes or gradients.
