When a particle orbits two axes simultaneously, the resultant orbital track appears to "tumble," but is in fact the synergetic result of the combination of two...
Hello, We're deciding on minimum system requirements for the next MacOS release. If anyone is running a system prior to MacOS 8.6, please let me know. Best...
Bob, This is a great example! You should upload it to the Files/Analytic Geometry folder, or I could do it for you if you. Showing all the elements, especially...
Bob, Well, at least I got a tetrahedron inside the sphere (attached file). Now if rotation matrices are applied to it, then we can see how the vertices line up...
Nice work Chris! Graphing Calculator helps enormously to visualize what the numbers are telling us. . Finding intersections in 3D seems like it should be akin...
I¹ve uploaded a couple more files on polyhedra and their relation to compound-circular-motion 3D curves. They¹re in Files > Analytic Geometry > Space curves...
OK, nemmie mind. When they downloaded I guess the file names got cut off. I just shortened them and added back the ".gcf" & they opened fine. Ready, fire,...
I just uploaded another file on Bob¹s conjecture about regular polygons and ³3D-circular-Lissajous² curves, or whatever they should be called. The file...
New file in the Files section in folder Analytic Geometry > Space curves > Compound. Rotating 4-hedron.gcf This shows how the tetrahedron vertices aren't quite...
Chris, The coordinates of the intersections of the (3:2) tetrahedron are (0,cos30,sin30) (0,-cos30,sin30) (cos30,0,-sin30) (-cos30,0,-sin30) I assume you've...
Answering my own question (Msg. 420). The horizontal edges of the tetra, i.e. those that have no z-component, have a length of SQRT 3. The other four, the ones...
Here¹s a file that might be the start of a general method to find the intersections of a 3D curve, either with itself or with another 3D curve. It¹s in the...
Bob, I¹m wondering where I can find more information on these curves, which are some of the nicest I¹ve come across. I haven¹t been able to find anything ...
Sorry, I once again forgot to put in the ³[x y z] =² that isn¹t necessary with the GC 3d4 development version (coming soon). I¹ll make it a point to always...
I found this book at Amazon.com and thought you might find it of interest. This is a fantastic book for learning both C# and Game Programming. It covers the...
Hello to all the CG users!!! I just purchase the software two days ago and it is a very impressive tool. Kudos Ron and everyone at Pacific Tech!! Regards, ...
Greetings all, This file GC 3.3d6 arrived a day or so back but I cannot get it to open the resulting updated version 3.2 Attempting to open GC 3.3d4 [I skipped...
Brian et al No, I did no have any problems updating the 3.2 (OS X 10.2.4 and OS 9.2.2 two-two not two-one)) However it quits quite often (more often than...

Kathy Of course I will. 1. Start by writing some dummy equation so that you have the two panes (equation pane and graph pane). 2. Copy any picture and paste it...

Hi folks, just joined when I couldn't make version 3.0 show me the asymptotes of a hyperbola. I've been using exploremath.com on a classroom set of Mac...
Our IT department is (finally) moving all the labs and lecture halls to Mac OS X. Once again this raises some old issues concerning a Mac OS X version of...
