Default constructor.

Member Data Documentation

p

Vector64 p

[READ WRITE] The rays position.

v

Vector64 v

[READ WRITE] The rays direction vector.

ior

Float ior

[READ WRITE] The current index of refraction.

pp

Vector pp[3]

[READ WRITE] 3 additional ray points for MIP-Mapping.

Note

.

P is the pixel origin or where the ray was generated.
0/1/2 are indices into the pp and vv arrays.
The square is one screen pixel wide in X and Y direction.

vv

Vector vv[3]

[READ WRITE] 3 additional ray vectors for MIP-Mapping.

Note

.

\n

P is the pixel origin or where the ray was generated.
0/1/2 are indices into the pp and vv arrays.
The square is one screen pixel wide in X and Y direction.

transport

Vector transport

[READ ONLY] The current ray intensity (for special shadow calculation). A ray starts with intensity 1.0.
