[x3d-public] [x3d] Spec Comment by on 19775-1: X3D Architecture - V4.0

[Brutzman, Donald (Don) (CIV)]

Thanks Doug. am not sure.  Have shared with x3d-public for further scrutiny.

 

Michalis, when defining FACTOR, can we say things more clearly to ensure
good alignment with glTF approaches?

 

all the best, Don

Sorry I was reading the committee draft, SELECT arg2 has been corrected in
Draft International Standard. 

But the confusion on the other one, FACTOR is still there


in freewrl looks like we've been using Multitexture.color and .alpha when
source is FACTOR.

And those values are provided once by Multitexture for all stages

Hypotheses:

H0: freewrl has been doing it wrong

H1: spec is unclear


"FACTOR"

The texture argument is the factor (color, alpha) from the texture provided
for the current stage of the MultiTexture node.

Change applied in git, ready for editor review/resolution (when Dick and I
next get together).  This should make it time for ISO DIS submission, they
are currently reviewing figures prior to acceptance.

 

all the best, Don
