In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "You can see in this code that besides setting the map property, we also set the bumpMap property to a texture."

A block of code is set as follows:

function createMesh(geom, imageFile, bump) {
  var texture = THREE.ImageUtils.loadTexture("../assets/textures/general/" + imageFile)
  var mat = new THREE.MeshPhongMaterial();
  mat.map = texture;
  var bump = THREE.ImageUtils.loadTexture("../assets/textures/general/" + bump)
  mat.bumpMap = bump;
  mat.bumpScale = 0.2;
  var mesh = new THREE.Mesh(geom, mat);
  return mesh;
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

var effectFilm = new THREE.FilmPass(0.8, 0.325, 256, false);
effectFilm.renderToScreen = true;

var composer4 = new THREE.EffectComposer(webGLRenderer);
composer4.addPass(renderScene);
composer4.addPass(effectFilm);

Any command-line input or output is written as follows:

# git clone https://github.com/josdirksen/learning-threejs

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "You can do this by going to Preferences | Advanced and checking Show develop menu in menu bar."
