Conventions

In this book, you will find a number of styles of text 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: "The number of work groups are determined by the parameters to glDispatchCompute."

A block of code is set as follows:

void main()
{
    Color = VertexColor;
    gl_Position = RotationMatrix * vec4(VertexPosition,1.0);
}

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

void main()
{
    Color = VertexColor;
 gl_Position = RotationMatrix * vec4(VertexPosition,1.0);
}

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

Active attributes:
1 VertexColor (vec3)
0 VertexPosition (vec3)

New terms and important words are shown in bold.
