The floating point triplet; used for texture parameters.

HT_Vertex_Set_Data::set_vertex_parameters, HT_Renderer::draw_2d_textured_polyline, HT_Texture::value, HT_Shape_Engine::draw_2d_polyline and HT_Shader::shade

Data Members

float u, v, w          Texture map parameters

HT_Parameter           Constructs and initializes an HT_Parameter object.

operator *             Scales the HT_Parameter  object by a scalar value.

operator *=            Scales the HT_Parameter object by a scalar value.

operator +             Adds an HT_Parameter object by another HT_Parameter, 
                                              object.

operator +=                              Adds  to this HT_Parameter object.

operator -             Subtracts an HT_Parameter object by another HT_Parameter, 
                                               object.

operator -=            Subtracts an HT_Parameter from this HT_Parameter object

operator ==            Compares two HT_Parameter objects for equality.

operator !=            Compares two HT_Parameter objects for inequality.

Purpose

Provides various arithmetic operators on HT_Parameterobjects.

HT_Parameter operator* (float scale)

HT_Parameter const & operator*= (float scale)

HT_Parameter operator+ (HT_Parameter const & right)

HT_Parameter const & operator+= (HT_Parameter const & right)

HT_Parameter operator- (HT_Parameter const & right)

HT_Parameter const & operator-= (HT_Parameter const & right)

int operator== (HT_Parameter const & parameter)

int operator!= (HT_Parameter const & parameter)

These operators provide the indicated arithmetic operations on the HT_Parameterobject.
 
 

Purpose

HT_Parameter()

HT_Parameter(
    float py,
    float pv,
    float pw
)
