Detailed Description

primitive: the parent class of all rendered objects

This class is the parent of all the primitives that get drawn to the screen.

Constructor & Destructor Documentation

glot::primitive::primitive

(

)

[inline]

Default constructor.

glot::primitive::primitive

(

const color &

col

)

[inline]

Constructor.

Parameters:

col

- the color of the primitive

Initializes the color of the primitive and the program GLenum

virtual glot::primitive::~primitive

(

)

[inline, virtual]

Destructor.

Virtual classes need virtual destructors

Member Function Documentation

virtual void glot::primitive::dl_gen

(

const screen &

s

)

[pure virtual]

Display-list generator.

Parameters:

s

- the screen specs

The screen stores the dimensions of the plot, etc. and based on that information, this function generates the geometry for the primitive. Typically this might be stored in a display list, but that is up to the container class, grapher

Implemented in glot::contour, glot::curve, glot::flow, glot::p_curve, glot::scalar_field, and glot::vector.

Member Data Documentation

color glot::primitive::c

The color of the the primitive.

Reimplemented in glot::curve, glot::p_curve, and glot::vector.

GLenum glot::primitive::p

Shader program handle.

Some primitives specify their own shader programs and the container class, grapher, will use each one's self-specified program when it's called.
