There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Scroll down to the draw method and add the following code beneath the identified line."

A block of code is set as follows:

void main() {
   float t = length(a_Position)/u_FurthestPoint;
   v_Color = vec4(t, 1.0-t,t,1.0);
   gl_Position = u_ModelViewProjection * vec4(a_Position.xyz, 1.0);
   gl_PointSize = u_PointSize;
}

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

uniform mat4 u_ModelViewProjection;
uniform vec4 u_Color;
uniform float u_PointSize;
uniform float u_FurthestPoint;

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

cd c:\Android
npm install http-server -g

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
