The default constructor does nothing. The vector coordinates will be uninitialized until you do a setValue() call.

Constructs an SbVec3f instance with initial values from v.

Constructs an SbVec3f instance with the initial vector endpoint set to <x,y,z>.

Constructs an SbVec3f instance by combining the three given planes. None of the planes should be parallel to any of the other two, otherwise a divide by zero error will occur.

Constructs an SbVec3f instance with initial values from the double precision vector v.

This is a Coin extension.

DEPRECATED for Coin 3.0 -- don't use this.

Since: Coin 2.0

Returns the result of taking the cross product of this vector and v.

Calculates and returns the result of taking the dot product of this vector and v.

Compares the vector with v and returns TRUE if the distance between the vectors is smaller or equal to the square root of tolerance.

Return the vector representing the principal axis closest to this vector.

Returns a pointer to an array of three floats containing the x, y and z coordinates of the vector.

See also: setValue().

Returns the x, y and z coordinates of the vector.

See also: setValue().

Return length of vector.

Returns the squared length of the vector.

Negate the vector (i.e. point it in the opposite direction).

Normalize the vector to unit length. Return value is the original length of the vector before normalization.

If the vector is the null vector, no attempt at normalization will be done, and if the Coin library was built in a debug version, this error message will then be shown:

    Coin warning in SbVec3f::normalize(): The length of the vector
    should be > 0.0f to be able to normalize.
  .fi


We've made Coin spit out a warning when an attempt at normalizing a null-vector is made, as that seems to always be a symptom caused by some graver error somewhere else -- either an internal error in Coin code, a programming error in application code, or an error in an input file (like for instance invalid polygon specifications).

If this happens, you should run the application in a debugger and see how the call-stack backtrace looks when it hits. An easy way of getting a debugger break at the warning spot is to set the following debugging environment variable which will make the code assert:


    COIN_DEBUG_BREAK="SbVec3f::normalize"
  .fi


If you from the backtrace analysis strongly suspects an internal Coin bug, please report the call-stack to us at coin-support@coin3d.org and we'll look into it. Example code that triggers the bug would then also be very helpful.

A note for developers porting code from SGI or TGS Inventor to Coin: those Inventor implementations are more slack about detecting and giving out warning messages upon API misuses, and you may suddenly have gotten this warning with Coin without seeing any indication of an error with SGI/TGS Inventor. This does not necessarily mean that it is a bug in Coin -- it is much more likely that you are getting a warning as an indication of API misuse or import file errors which were just not detected and/or reported with those Inventor implementations. 

Set new coordinates for the vector from v. Returns reference to self.

See also: getValue().

Set new coordinates for the vector. Returns reference to self.

See also: getValue().

Set this vector to be the average of v0, v1 and v2. The vector components are weighted by the barycentric vector.

See also: getValue().

Sets this vector to the double precision vector v, converting the vector to a single precision vector.

This is a Coin extension.

Multiply components of vector with scalar value d. Returns reference to self.

Divides components of vector with scalar value d. Returns reference to self.

Adds this vector and vector u. Returns reference to self.

Subtracts vector u from this vector. Returns reference to self.

Non-destructive negation operator. Returns a new SbVec3f instance which points in the opposite direction of this vector.

See also: negate().

Dump the state of this object to the file stream. Only works in debug version of library, method does nothing in an optimized compile.
