◆ Ray()

(

)

Default constructor.

Member Data Documentation

◆ p

[READ WRITE] The rays position.

◆ v

[READ WRITE] The rays direction vector.

◆ ior

Float ior

[READ WRITE] The current index of refraction.

◆ pp

向量 pp[3]

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

注意

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

向量 vv[3]

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

注意

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

向量 transport

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