(m+1) * (n+1) a model vertices.
2, vertex is converted.
The vertex that sampling comes out is Viewport coordinate, can only obtain a direction in world coordinate system, can't calculate
Position in real world.So calculating world coordinates by point cloud data.Calculation method is as shown in table 1:
Table 1
Centre of sphere O
A point P on spy face
Vertical point N of the centre of sphere to spy face
Depth=OP
D=ON
Depth=d/cos (θ)
Ab=| a | | b | cos θ
Deriving final formula is
Depth=d/ (pnx*nx+pny*ny+pnz*nz)
