Inheritance:

Public Methods
DVobject(): Contructor.
virtual ~DVobject(): Default destructor.
DVobject& set_translate(LCVMarray<float> &data): Set the translation
DVobject& set_translate(const float x, const float y, const float z): Set the translation
DVobject& add_translate(LCVMarray<float> &data): Add the given translation to the translation already there.
DVobject& add_translate(const float x, const float y, const float z): Add the given translation to the translation already there.
DVobject& set_rotate(LCVMarray<float> &data, const float angle, const char type='d'): is in radians ('r') or degrees ('d'-by default)
DVobject& set_rotate( const float x, const float y, const float z, const float angle, const char type='d' ): is in radians ('r') or degrees ('d'-by default)
DVobject& add_rotate(LCVMarray<float> &data, const float angle, const char type='d'): Add the given rotation to the rotation already there.
DVobject& add_rotate( const float x, const float y, const float z, const float angle, const char type='d' ): Add the given rotation to the rotation already there.
void get_translation(LCVMarray<float>&): Get the translation
void get_rotation(LCVMarray<float>&, float&): Get the rotation
virtual void draw(LCVMstack<DVproperty*>&): The draw routine.
void set_OpenGL_lighting_properties(DVlight_properties_property_item_array &lights): A routine to set lighting properties for OpenGL
void set_OpenGL_material_properties(DVmaterial_properties_property_item &material, DVcolor &color): A routine to set material properties for OpenGL
void set_OpenGL_color(DVcolor &color): A routine to set color for OpenGL
virtual DVobject& copy_child(DVobject &child): Function to be declared in derived classes. This is only a place holder.
virtual DVobject& delete_current_child(): Function to be declared in derived classes. This is only a place holder.
DVobject(const DVobject &data): Copy constructor
const DVobject& operator=(const DVobject &data): Assignment operator
int operator==(const DVobject &data): Check for equality
int operator!=(const DVobject &data): Check for not equality
virtual void print(ostream &): Virtual print function so that we can print instantiations of the various classes derived from DVobject
friend ostream& operator<<(ostream &, DVobject &): A friend routine to overload the << operator
int ReadProp(): Read the object properties from a scene file.
void ReadDVrotate(): Read the object rotation from a scene file.
void ReadDVtranslation(): Read the object translation from a scene file.
void ReadSimpleProps(): Read the object properties from a scene file A simple loop on <tt/ReadProp()/ : while it detects a simple property, it reads it.

Public
: Set the rotation with an axis (data), an angle and specifying if it
: Set the rotation with an axis (x,y,z), an angle and specifying if it

Protected Fields
class DVcontainerbase LCVMarray<float> translation: The tranlation of the object.
LCVMarray<float> rotation_axis: Set the axis about which the orientation of the object is rotated
float rotation_angle: The angle about the axis by which the orientation of the object is changed
LCVMarray<float> rotation_quaterions: The orientation may also be set by entering quaterions.

Protected Methods
virtual DVobject* copy(): We also want a routine that returns a pointer to a copy of the object created with new.
void axis_to_quat(LCVMarray<float> axis, float angle, LCVMarray<float> &quat): A convenience routine to change vector angle format to quaternions
void quat_to_axis(LCVMarray<float> quat, LCVMarray<float> &axis, float &angle): A convenience routine to change quaterions to vector angle format
void add_quat(LCVMarray<float> a, LCVMarray<float> b, LCVMarray<float> &c): Add two quaterions a+b = c

Documentation

The top of the DataViewer class hierarchy. All renderable objects in DataViewer inherit from this class. It contains attributes which apply to a wide range of geometrical objects, position, rotation, etc.

class DVcontainerbase LCVMarray<float> translation

The tranlation of the object. Normally interpreted as the center of the object.
