class HT_Camera

class HT_Camera_Obliquity

Auxiliary class for class HT_Camera, containing a pair of floats used to define camera obliquity. A companion class, HT_Camera_Obliquity_D, provides double precision and is similar in functionally.

For more information, see the section "Camera Classes," in chapter 2, "Heidi Architecture."

float x, y

Angular measure used to define shear transformation
associated with obliquity. Operators

operator ==

Returns HK_True if two HT_Camera_Obliquity
values compare equally.

operator !=

Returns HK_True if two HT_Camera_Obliquity
values do not compare equally. Constructor

HT_Camera_Obliquity

Constructs an HT_Camera_Obliquity object.

HT_Camera_Obliquity::HT_Camera_Obliquity

Purpose

Initializes a new camera obliquity object Synopsis

HT_Camera_Obliquity ()

HT_Camera_Obliquity (float px, float py)

HT_Camera_Obliquity(HT_Camera_Obliquity_D const & obl)

Details The first form, HT_Camera_Obliquity(), initializes x and y obliquity values to zero.

The second form copies the px and py obliquity from the parameters.

Given double precision, the third form generates a floating point.

HT_Camera_Obliquity::operator ==

Purpose

Returns HK_True if two HT_Camera_Obliquity values are equal. Synopsis

HT_Boolean operator== (HT_Camera_Obliquity const & compare)const

HT_Camera_Obliquity::operator !=

Purpose

Returns HK_True if two HT_Camera_Obliquity values are not equal. Synopsis

HT_Boolean operator!= (HT_Camera_Obliquity const & compare) const

HT_Camera_Obliquity::x, y

Purpose

Angular measure used to define shear transformation associated with obliquity. Synopsis

float x;

float y;

Details HT_Camera_Obliquity.y gives the angle, measured in the metric of the camera system, between the Z_C axis and the projection on the X_CZ_C plane of the Z_V axis. HT_Camera_Obliquity.x gives the angle between the Z_C axis and the projection on the Y_CZ_C plane of the Z_V axis
