Function Documentation

Real dtor (  Real  d  )  [inline]

Convert degrees to radians. Definition at line 65 of file real.inl. References sheep::PI. Referenced by toxic::SceneBuilder::mesh_builder(), toxic::SceneBuilder::pinholecamera_builder(), toxic::SceneBuilder::rotation_builder(), and toxic::SceneBuilder::thinlenscamera_builder().

bool feq (  Real  a, Real  b, Real  e = EPS )  [inline]

Equal: a == b. Used to test two floating point numbers to see if they are close enough to be considered equal (not equal, less or equal, greater or equal, zero, not zero). Based on code by Robert Martin (rmartin@rcmcon.com). Definition at line 24 of file real.inl.

bool fge (  Real  a, Real  b, Real  e )  [inline]

Greater or equal: a >= b. Definition at line 45 of file real.inl. References feq().

bool fle (  Real  a, Real  b, Real  e )  [inline]

Less or equal: a <= b. Definition at line 40 of file real.inl. References feq().

bool fneq (  Real  a, Real  b, Real  e )  [inline]

Not equal: a != b. Definition at line 35 of file real.inl. References feq().

bool fnz (  Real  a, Real  e )  [inline]

Not zero: a != 0. Definition at line 55 of file real.inl.

bool fz (  Real  a, Real  e )  [inline]

Zero: a == 0. Definition at line 50 of file real.inl.

int NextPowerOfTwo (  double  x  )  [inline]

Returns the smallest integer which can be expressed as a power of two, and which is greatest than x. x must be >= 1. Definition at line 81 of file real.inl. Referenced by sheep::Texture::set_texture().

Real NormalizeAngle (  Real  angle  )  [inline]

Expresses a given angle to [0, 2*Pi]. The input and output angles are expressed in radians. Definition at line 75 of file real.inl. References sheep::PI. Referenced by PackSphericalCoords(), and sheep::SceneOrbiter::tumble().

Real rtod (  Real  r  )  [inline]

Convert radians to degrees. Definition at line 70 of file real.inl. References sheep::PI. Referenced by display().

template<typename T> T sq (  T  x  )  [inline]

Definition at line 60 of file real.inl. Referenced by toxic::Ring::Intersect(), IsSquare(), sheep::MeshModifier::sub_mesh::OptimizeVertices(), sheep::Arcball::point_on_sphere(), and toxic::Ring::Ring().
