Member Function Documentation

static GfVec4f GfVec4f::Axis ( size_t i )

inlinestatic

Create a unit vector along the i-th axis, zero-based. Return the zero vector if i is greater than or equal to 4.

Definition at line 110 of file vec4f.h.

float const* GfVec4f::data ( ) const

Direct data access.

Definition at line 134 of file vec4f.h.

GfVec4f GfVec4f::GetComplement ( GfVec4f const & b ) const

inline

Returns the orthogonal complement of this->GetProjection(b). That is:

*this - this->GetProjection(b)

Definition at line 241 of file vec4f.h.

float GfVec4f::GetLength ( ) const

inline

Length.

Definition at line 251 of file vec4f.h.

inline

Definition at line 271 of file vec4f.h.

GfVec4f GfVec4f::GetProjection ( GfVec4f const & v ) const

inline

Returns the projection of this onto v. That is:

v * (*this * v)

Definition at line 232 of file vec4f.h.

float GfVec4f::Normalize ( float eps = GF_MIN_VECTOR_LENGTH )

inline

Normalizes the vector in place to unit length, returning the length before normalization. If the length of the vector is smaller than eps, then the vector is set to vector/eps. The original length of the vector is returned. See also GfNormalize().

Todo:: This was fixed for bug 67777. This is a gcc64 optimizer bug. By tickling the code, it no longer tries to write into an illegal memory address (in the code section of memory).
