When you run a script, NodeBox reads the code from top to bottom, like a recipe. Then all subsequent elements you draw have that color. All of the elements you draw have the same color, until you switch to a different color. So in NodeBox you "paint" with one color. Naturally, you could paint with both hands and feet holding multiple brushes with multiple colors. And the same texture according to the thickness and softness of the brush. All the lines you then paint on the canvas have the same color. When painting, you can hold one type of brush and put one color of paint on it. Image(self.img, 0, 0, self.img_width, self.The graphics state stores your current color and transformation settings. # max width and height are x1.5 of the original # min width and height are half of the original width and height

If you prepare properly photoshopped facial images, you can rotate eyes of it. This sketch wobbles, rotates, stretches images. Tutorial about classes helped me a lot when I wrote this sketch. It is quite a fine language and I like it, but latest nodebox(Nodebox3) has become a node-based language as its name says and nodebox 1 doesn’t have some functions processing has such as imageMode().īy the way, tutorial of nodebox 1 might help you if you don’t know much about python. I prefer python mode to Nodebox, which is also a graphic programming language written in python. They implemented python mode recently, which enables us writing processing code in python syntax and liberate from semicolons and curly brackets. I wrote a sketch in python mode of Processing.
