Detailed Description

Each object consists of a collection of vertices and a collection of faces. Objects also store a bounding box.

Constructor & Destructor Documentation

Object::Object

(

std::string

name

)

Constructs an empty object.

Parameters:

name	is the name of the new object.

Member Function Documentation

void Object::applyGT

(

const QMatrix4x4 &

mat

)

Applies geometric transform to all vertices; updates normals & bounding box.

Box Object::boundingBox

(

)

const

Returns the value of the bounding box property. This property is undefined unless computeBoundingBox() has been called.

void Object::computeBoundingBox

(

)

Recomputes the object bounding box.

void Object::computeNormals

(

)

Recomputes per-face normals (for all faces of the object).

const vector< Face > & Object::faces

(

)

const

Returns a constant reference (read-only) to the vector of faces of the object.

void Object::readObj

(

const char *

filename

)

Imports a Wavefront OBJ file as a single object. Previous faces and vertices, if any, are deleted.

const vector< Vertex > & Object::vertices

(

)

const

Returns a constant reference (read-only) to the vector of vertices of the object.

vector< Vertex > & Object::vertices

(

)

Returns a reference to the vector of vertices of the object. If vertices are modified, computeNormals() and computeBoundingBox() methods should be called to update per-face normals and the object's bounding box.
