|wwwmwww Wrote:Well by rectangles I assume you mean boxes and by triangles I assume you mean triangular prisims. If so I don't recall seeing 5 primitives used to make the shape you describe. As I recall what is seen on the DVD is 1 triangular prisim and 2 right trapezoidal prisims. However if MAGI's software could extrude a right trapezoid into a prisim I really don't see why it could extrude any polygon into a prism.|
Correct, rectangle == cubes, boxes, etc. and triangles == prisms, etc.. I guess, technically, a polygon in 3D is called a polyhedron. I don't know if they could to trapezoids. They may have had to use a sheer transformation on a cube to get the shape instead of just having the primitive directly? But Perlin started right there that they could not use polygons, so I have to assume the available primitive set was pretty limited, thus a lot of boolean operations to get some shapes we can do directly, like this:

Do you have any screenshots that show this clearly? It would save primitives, but we do know they had cut-cones which could do the same thing, albeit with 1 more primitive. It seems it would be a pain in the butt to get an ellipse into the exact shape needed. The wing ellipse was probably the hardest shape for me to get just right.
|wwwmwww Wrote:And while we are talking about that image look at this:|
I think that big part sticking out the top is the windshield cutter and/or the part that makes the windshield black.
The part you are pointing to with blue arrows looks like a box used to AND with the canopy (just the canopy cylinder and taper), and the predominantly larger box seen here is used to AND with the canopy shoulders and upper half of the sides.
The large circular shape (rooster tail looking), could be the jet wall arc or the wheel well cutter. I originally cut my wheel well with another torus, but later changed it to a sheered cylinder.
The two smaller parts in the back, I have no idea. It's too hard to determine from this angle. What I want to know is, what is that circle on the front wheel?
|wwwmwww Wrote:I wonder if one of them might be related to the rear wheel cutter. At the moment my model uses 2 spheres but I'm starting to wonder if that cutter should really be just a strait cylinder. I now need to go back and see if I can convince myself that there is or isn't a taper in from the edge of he rear wheel cut to the start of the rear wheel hub. If you have any good shots of this area please post. Maybe I can get rid of one more primitive.|
I always thought the inside of the rear wheel was tapered in a little too, but I'll have to go back and look at some images now. I'm currently using two ellipses as cutters as well. I guess it would make more sense to be cut with a cylinder since the rear hub is a cylinder (a very thin cylinder.)
I have to run right now, I'll comment on your all-view image in a bit, but it's looking really good!
