|
Default constructor. The default value of the instantiated point will be (0.0,0.0,0.0,0.0). |
|
Construct new point. The value of the point will be (rdX, rdY, rdZ, 1). |
|
Construct new point. The value of the point will be (rdX, rdY, rdZ, rdW). |
|
Copy constructor. The parameters will be simply copied. |
|
Converts a point to a vector. It's implemented as 'get'-method to prevent implicit casting by the compiler. |
|
Returns the w-coordinate of the point. |
|
Returns the x-coordinate of the point. |
|
Returns the y-coordinate of the point. |
|
Returns the z-coordinate of the point. |
|
Cast operator to convert CP4D points to CP3D points. Each component is devided by the fourth component. |
|
Compares to points for not being equal. Same as operator== but inverted.
|
|
Adds a vector to a point. |
|
Adds a vector to this point. |
|
Negates the point. |
|
Subtracts a vector from a point. |
|
Subtracts two points. The resulting vector is returned. |
|
Subtracts a vector from this point. |
|
Assign one point to another. |
|
Compares to points for being equal. The result will be 'true'(1) if the two point are indentically up to <= CP4D::epsilon for each component. Otherwise 'false'(0) will be returned. |
|
Same as above but does not alter anything. |
|
Returns the i-th component of the point. The index goes from 0 to 3, 0 stands for the x-coordinate, 1 for the y-coordinate and so on. |
|
Prints a point to the standard output. |
|
Set the values of the point. The value of the point will be (rdX, rdY, rdZ, rdW). |
|
Sets the w-coordinate of the point to 'rdW'. |
|
Sets the x-coordinate of the point to 'rdX'. |
|
Sets the y-coordinate of the point to 'rdY'. |
|
Sets the z-coordinate of the point to 'rdZ'. |
|
Returns the affine combination of the points and vectors. |
|
Same as above. But more useful for streams. |
|
Reads a point from the given stream. |
