Detailed Description

General class used to render boxes as GlEntity.

This class is a generic class to render boxes as GlEntity.

Constructor & Destructor Documentation

tlp::GlBox::GlBox ()The default constructor

Attention:

It's usage is forbidden.

tlp::GlBox::GlBox (const Coord & position, const Size & size, const Color & color)Constructor from size

Parameters:

position The center of the box.
size The length of each dimension of the box.
color The color of the box.

tlp::GlBox::GlBox (Coord points[8], const Color & color)Constructor from points

Parameters:

points Each point of the box. c.f. the variable 'points' to know the placement.
color The color of the box.

tlp::GlBox::GlBox (const Coord & frontTopLeft, const Coord & backBottomRight, const Color & color)Constructor from bounding box

Parameters:

frontTopLeft The position of the point at the front-top-left of the box (points[0]).
backbottomRight The position of the point at the back-bottom-right of the box (points[6]).
color The color of the box.

virtual tlp::GlBox::~GlBox () [virtual]Destructor.

Member Function Documentation

void tlp::GlBox::computeFaces () [protected]Function used to compute the GlADQuad from the points of the box.

void tlp::GlBox::computePoints () [protected]Function used to compute the points of the box from a center and a size.

virtual void tlp::GlBox::draw (float lod, Camera * camera) [virtual]Virtual function used to draw the box.

Implements tlp::GlSimpleEntity.

Size* tlp::GlBox::getSize () constAccessor in reading to the size.

virtual void tlp::GlBox::getXML (xmlNodePtr rootNode) [virtual]Function to export data in XML

Implements tlp::GlSimpleEntity.

void tlp::GlBox::setPosition (const Coord & position)Accessor in writing to the position.

Member Data Documentation

Color* tlp::GlBox::color [protected]The color of the box

Coord* tlp::GlBox::points[N_BOX_POINTS] [protected]The coordinates of each of the 8 points of the box.

Attention:

points[0] = front top left

points[1] = front top right

points[2] = front bottom right

points[3] = front bottom left

points[4] = back top left

points[5] = back top right

points[6] = back bottom right

points[7] = back bottom left

Coord* tlp::GlBox::position [protected]The position of the center of the box

Size* tlp::GlBox::size [protected]size is the 'radius' of the box
