Detailed Description

Basic type for a vector of 2 float components.

Represents a vector of 2 components of type float. It is intended to be fast and simple.

Member Function Documentation

static GfVec2f GfVec2f::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 2.

Definition at line 115 of file vec2f.h.

float const* GfVec2f::data ( ) const

inline

Direct data access.

Definition at line 135 of file vec2f.h.

float* GfVec2f::data ( )

inline

Definition at line 136 of file vec2f.h.

float const* GfVec2f::GetArray ( ) const

inline

Definition at line 137 of file vec2f.h.

GfVec2f GfVec2f::GetComplement ( GfVec2f const &  b ) const

inline

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

*this - this->GetProjection(b)

Definition at line 236 of file vec2f.h.

float GfVec2f::GetLength ( ) const

inline

Length.

Definition at line 246 of file vec2f.h.

float GfVec2f::GetLengthSq ( ) const

inline

Squared length.

Definition at line 241 of file vec2f.h.

GfVec2f GfVec2f::GetNormalized ( float  eps = GF_MIN_VECTOR_LENGTH ) const

inline

Definition at line 266 of file vec2f.h.

GfVec2f GfVec2f::GetProjection ( GfVec2f const &  v ) const

inline

Returns the projection of this onto v. That is:

v * (*this * v)

Definition at line 227 of file vec2f.h.

float GfVec2f::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).
