Member Function Documentation

void WPCG::WP_Point3D::draw   const [inline]
 

this function draws the 3D point to the screen using OpenGL

WP_Point3D& WPCG::WP_Point3D::operator *= const WP_Matrix3D   m [inline]
 

this operator multiplies the current point by a matrix

Parameters:
m  a WP_Matrix3D object representing the matrix by which this point is multiplied
Returns:
a reference to this object containing the new point values after multiplication by the matrix

WP_Point3D WPCG::WP_Point3D::operator+ const WP_Vector3D   v const [inline]
 

this operator adds a vector to this point resulting in a new point

Parameters:
v  a WP_Vector3D object representing the vector which is added to this point
Returns:
a WP_Point3D object representing the new point

WP_Vector3D WPCG::WP_Point3D::operator+ const WP_Point3D &    p const [inline]
 

this operator adds a point to this point resulting in a vector

Parameters:
p  a WP_Point3D object representing the point which is added to this point
Returns:
a WP_Vector3D object representing the vector

WP_Point3D& WPCG::WP_Point3D::operator+= const WP_Vector3D   v [inline]
 

this operator adds a vector to this point resulting in a new point

Parameters:
v  a WP_Vector3D object representing the vector which is added to this point
Returns:
a reference to this object containing the new point values after the addition of the vector

WP_Point3D WPCG::WP_Point3D::operator- const WP_Vector3D   v const [inline]
 

this operator subtracts a vector from this point resulting in a new point

Parameters:
v  a WP_Vector3D object representing the vector which is subtracted from this point
Returns:
a WP_Point3D object representing the new point

WP_Vector3D WPCG::WP_Point3D::operator- const WP_Point3D &    p const [inline]
 

this operator substracts a point from this point resulting in a vector

Parameters:
p  a WP_Point3D object representing the point which is subtracted from this point
Returns:
a WP_Vector3D object representing the vector

WP_Point3D& WPCG::WP_Point3D::operator-= const WP_Vector3D   v [inline]
 

this operator subtracts a vector from this point resulting in a new point

Parameters:
v  a WP_Vector3D object representing the vector which is subtracted from this point
Returns:
a reference to this object containing the new point values after the subtraction of the vector

WP_Point3D& WPCG::WP_Point3D::operator= const WP_Point3D &    p [inline]
 

assignment operator

Parameters:
p  the WP_Point3D object which is copied to this object
Returns:
a reference to this object containing the copied point values

void WPCG::WP_Point3D::set const WP_Vector3D   v [inline]
 

this function converts a vector to a point by setting the x, y, and z values of the vector in the point

Parameters:
v  the vector which values are taken and set in this point

WP_Vector3D WPCG::WP_Point3D::toVector   const [inline]
 

this function creates a vector from this point's x, y and z values

Returns:
a WP_Vector3D object representing the created vector


Member Data Documentation

scalar WPCG::WP_Point3D::data[4]
 

an array of scalars representing the homogenous point, so data[0] = x, data[1] = y, data[2] = z and data[3] = 1.0f
