Changes.doc UpDated: 1/7/92 This is a quick list of the changes in this version of Vertex. If this is an update version for you, then you can bypass re-reading the entire manual, if you wish, unless specific details are mentioned which are only present in the updated manual. Changes to Version 1.28 - Registered Update for Preferred Users (1/7/92) . Most (All I hope) of the bugs present from the changes made in the previous version have been taken care of. . I've added some real-time indicators to let you know about transforming objects with the mouse. The bottom line will now tell you how much you are scaling, sizing or moving objects in any of the transform free functions. . The Arexx port is not working correctly. For some reason, the port name "VERTEX" does not show up from within Arexx. Please do not expect to use the Arexx port, as I cannot guarantee it will even be available. This is one of the things I am currently working on. Changes to Version 1.26 (1/1/92) . Objects saved in Turbo Silver/Imagine will be created on their centroid, instead of all the objects overlapping one another. . Sped-up the Turbo Silver/Imagine save routine. It only loops through the faces once now. . Optimized view calculations when Front, Top and Side views are chosen, and no view rotations need to be calculated. . Tried to optimize the extrude and bevel commands. They should work somewhat faster now. . Added the select exterior edges routine. See the manual. . Added the Delete useless routine - see the manual. . Added the ability to hide vertices. Hidden verticies may not be selected or modified. . Greatly sped-up the add-face command. It won't delay after exiting the function. . I made sure the unselected vertices are drawn first, and then the selected vertices are drawn. Should make it easier to see selected vertices now. . A command was added to find the distance from one vertex to another. . Pick and Unpk buttons were added to the main window. Once selected, you may select vertices by clicking right on them or stretching a selector box. Again, press the right mouse button to exit the selection mode. Changes to Version 1.24 (12/29/91) . Added a gravity (magnet) interface. The gravity will attract or repell vertices based on their distance from the centroid of the selected vertices. Also, the newly included Hot Spot can become the center of gravity. . Added a Hot Spot which replaces the center of everything. Formerly, Vertex relied on the centroid (or average) of all selected vertices to perform certain transformations. Now you can place a moveable hot spot to replace this. The hot spot is sticky - in that it will attach itself to a vertex if you place it over a vertex. . Added the Overlay Fuse command. This will attempt to do a fuse of all vertices which are on top of one another. With it, you can connect objects. . Object names in Turbo Silver and Imagine are now saved with the file. (Former versions didn't even attempt to do this) There are important side effects of this new feature, so make sure and read the documentation on the Impulse Save command. (See the manual!) . Bugs fixed: - Transform Point-Move will now correctly handle the view positions. (Before it didn't take them into account) - Subdivide Edges will name the new vertex the same as the other two vertices at the endpoints. - Planar fill works now! (Sorry about that one, I completely forgot to repair it after changing another routine) - Fuse Vertices will always work, unless you specifically cancel it. - I made some changes to the File writing routines to better capture errors. Changes to Version 1.23 (12/27/91) . Lots of little bug fixes. I fixed the Transform-Point move routine to reflect the current zoom level, and corrected the problems with vertex names across bevel, extrude and duplicate. . I've also included a printable version of the documentation for the registered user. Currently, it is 67 pages, and contains a simple table of contents. Once I finish my indexing program, we'll have an index. The file contains the form feed character (ctrl-L), so pages will be split. Hope this helps. Changes to Version 1.22 (12/24/91) . Wavefront file reading has been further repaired. It now relies on the .obj on the end of the file to determine it it's type. . The bevel routine has been further improved. It will currently bevel up to 1000 vertices. Whats more, the bevel will be correct, even on very tight corner angles. ie. no "windshield wiper" effect. . A new point editing routine has been added under the transform menu. It's called Point Move, and it works by selecting a number of vertices, then it enables you to move those points individually. Check out the manual on this one - I'm sure many people will find it helpful. . Apply curve has been fixed completely! (I hope!) Well, it should not forget any vertices now, and the interface has been re-worked to make it easier to understand. . A subdivide edge command has been added to add detail to your objects. Read the docs for the skinny on this function. . I re-did the Lightwave loading routines - they should be a little faster. I just recieved the real docs on this file format, so you should be seeing the promised face attribute stuff shortly. . The limit for vertices, edges and faces has been expanded to 64000. Currenty, this is the absolute limit, although I have plans to re-work some of the loading and saving routines to open this up. Changes for Version 1.19 - Registered Update for Preferred Users (12/17/91) . The Wavefront file format has been repaired. Unfortunately, Wavefront seems to be in the "habit" of changing their file format. The docs I used, dated January 1991, are already out of date. The problems have been fixed. . The anim-render mode has been fixed. I had the workbench screen colors inverted (0 and 1) so 2.0 users were seeing a black image drawn on a black screen. . The Basic Shape-Sphere routine has been fixed. Certain values which did not divide into 360 were causing odd-shaped spheres to be created. . The mouse reading routine was slowed down. Some Amiga's, especially ones with 3rd party mice, were reading the mouse click too fast. . Extrude is now smarter. It will not create faces on the interior of the extruded object, which never get rendered anyway. . A Bevel Edges command has been added, under Modify. This will extrude, then "router" the edges of a flat object. I would strongly suggest reading the manual for further information on this command. . I have double checked the "too much memory" problem of older versions. To date, I have sucessfully run Vertex on an Amiga 3000 UX with 8 megs, and an Amiga 2000 w/1.3 and 2.0 with 10megs. If you have further problems with this, please notify me, and include descriptions of your system set-up and what actually happened at load time. . Error catching and correction has been greatly improved. Errors are now correctly trapped at File Loading/Saving, Multiply, and render. Vertex, edge and face overflow errors are on my list. In order to speedily return from these errors, hooks have to be put in which would greatly slow down performance. Hopefully, the next version will see this problem solved. . A new option has been added to the Lathe Menu. It is called Rewind Lathe. This will enable you to quickly re-create the last lathe created, without having to re-define it yourself.
