GreG, This looks decidedly impressive. I have to ask what the model is? Something you made from clay or something? And how many points are in the wireframe? There is an ample amount of detail, certainly. The question of digitization vs point-pulling is like the question of OCR vs key-entry : it's really a matter of time required to accomplish the same end with two different means. Does the Digi-Max save you (total) a significant amount of time?

>> This looks decidedly impressive. I have to ask what the model is? Something you made from clay or something? << Gary, I used a vinyl model kit of the Alien object that I purchased at a hobby store. I had it laying around, was gonna actually build it, airbrush it, mount and encase it, when I decided to chop it up and digitize it. >> And how many points are in the wireframe? There is an ample amount of detail, certainly. << Ok, I digitized that object in 3 parts so far. The head, upper torso, lower torso. I also only digitized the right side of the object, then mirrored it to get the left side. Saves time to do it that way, rather then digitize it whole. With somewhat symetric objects it just makes sense. Right side of Head object: 787 points 1457 Faces Right side of Upper torso: 1157 points 2174 Faces Right side of Lower torso: 865 points 1533 Faces To get the total point count just add the three and multiply by two. I could have done it with less detail, but I wanted to be able to get in close without losing any of the subtleties. I could have also used more detail, but thought that would have been overkill. >> The question of digitization vs point-pulling is like the question of OCR vs key-entry : it's really a matter of time required to accomplish the same end with two different means. Does the Digi-Max save you (total) a significant amount of time? << It does when working with organic objects that you want an accurate model of. Again, it really depends on the object you are talking about. Some objects I wouldn't want/need to digitize, other's I would. The DigiMax can also be used to rough out the shape of an object for detailing manually. It all depends on the object, and what you want your end product to be.

GreG — Oh, THAT alien! The Sigourneyensis gloppyei. Sorry, it didn't register, it's been too many years. I can see that it would be helpful to digitize on some occasions. How many points per minute do you think you average when you are entering an object like this? And is it necessary to enter them in a deliberate sequence to keep the polys from getting tangled? Or does it keep the snarls out automatically? regards, GB

>> How many points per minute do you think you average when you are entering an object like this? << Gary, I haven't timed it. <g> Digitizing goes by pretty quickly…I have the probe in hand (no jokes Sam, or JohnS, or Stephen, or anyone else!), and my other hand is draped over the axis rotation knob with my finger right on the button that is pressed to enter that coordinate. Once you've developed your "groove" it's a matter of move/click, move/click, etc. >> And is it necessary to enter them in a deliberate sequence to keep the polys from getting tangled? Or does it keep the snarls out automatically? << It's not necessary, but I've found it best to enter the vertices in some type of order. Actually, thats the only way to do it without really getting messed up. The nice thing about the software though, is that you can always go back and add points to any part of the mesh in any random order. This is usefull for adding detail to areas that were only roughed out in a cursory pass. You can also alternate between this mode(forget the name at the moment), and the lofting mode. -GreG

It's a good feature to have. Also, I'm assuming the probe does not need to be in contact with the object being digitized? As in, "I want this point this far off the actual surface" ? Thanks for the briefing, GreG regards GB
