Subject: dr3d terminology issues
Greetings! There are a number of terminology problems with the dr3d attributes. The following is illustrative and not exhaustive: > |dr3d:edge-rounding-mode| attribute specifies how to generate rounded > edges. > > The values of this attribute are: > > * > > |attractive| - the outer faceplates of extruded objects are > preserved, but inner faceplates are 'grown' in normal direction > > * > > |correct| - faceplates of extruded objects are linearly scaled > smaller, but the original polygons are kept for the object outline > Note that "attractive," "correct," "faceplates," and "grown" are unknown at www.web3d.org. You will find ISO standards for X3D at: http://www.web3d.org/x3d/specifications/ Or consider: > The |dr3d:lighting-mode| attribute specifies the lighting algorithm > used to render a 3D object. > > The value of this attribute can be |standard| or |double-sided|. If > the value is |double-sided|, the reverse sides of the object are also > lighted. > We may have to use these attribute values but we should define them using standard terminology. X3D speaks variously of "front" or "back" face, "front" or "back" side. Or consider: > The |dr3d:max-edge| attribute specifies the maximum edge of a cube in > a 3D space. > > The |dr3d:min-edge| attribute specifies the minimum edge of a cube in > a 3D space. > As far as I can tell, the terms "maximum edge" and "minimum edge" do not occur in X3D. Searching more broadly, it appears that "maximum edge" and "minimum edge" may refer to maximum edge length and minimum edge length, but I can't say for sure. In the short run, this version, I don't think we can do more than simply provide definitions for the terms we use. In the long run, deprecating dr3d entirely and adopting X3D by reference would be the better solution. Then applications can claim conformance to ODF and as much (or as little) of X3D as they care to implement. It would have the added advantage that I would not have to worry about what X3D says since that would be some other editor's problem. ;-) Hope everyone is having a great weekend!
