Conventions used

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

Code in text: 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: "Use the vertex color data from our Input struct to be assigned to the o.Albedo parameters in the built-in SurfaceOutput struct."

A block of code is set as follows:

void surf (Input IN, inout SurfaceOutput o) 
{
  o.Albedo = IN.vertColor.rgb * _MainTint.rgb;
}

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

struct Input 
{
  float2 uv_MainTex;
  float4 vertColor;
};

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: "From its Inspector tab, make sure that Filter Mode is set to Bilinear."
