Detailed Description

References a contiguous loop-fan. Combined with the automatically calculated face corner normal, this gives a dimensional coordinate space used to convert normals between the "custom normal" short2 representation and a regular float3 format.

◆ ref_alpha

float MLoopNorSpace::ref_alpha

Reference angle around vec_ortho, in ]0, pi] range, between vec_lnor and the reference edge.

A 0.0 value marks that space as invalid, as it can only happen in extremely degenerate geometry cases (it would mean that the default normal is perfectly aligned with the reference edge).

◆ ref_beta

float MLoopNorSpace::ref_beta

Reference angle around vec_lnor, in ]0, 2pi] range, between the reference edge and the other border edge of the fan.

A 0.0 value marks that space as invalid, as it can only happen in degenerate geometry cases (it would mean that all the edges connected to that corner of the smooth fan are perfectly aligned).
