This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

3Ded - User Guide ----------------- Here is a short guide on how to use 3Ded, a simple 3D object and scene editor. 1. Screen layout The editor screen is arranged into clearly defined sections. Along the top is the main menu - click on these options to select the editing mode or enable/disable various options (see below). The bulk of the screen is taken up with four views of the object being editing - one 3D and three 2D. The 2D views are not shown with perspective and are the ones used for actual editing. The 3D view is provided purely to show how your 3D scene or object looks and cannot be used for editing itself. At the bottom of the screen are displayed co-ordinates and angles where appropriate. On the right is shown either a complete list of objects, which may be scrolled up and down, or a colour selector for when you define or edit individual polygons. Below the menu at the top of the screen is the name of the object being edited and to the right of this any 'flags' associated with it. 2. Getting started To try out the editor, click on LOAD and load our Cathedral file. By default the object 'world' is selected - every file must have a 'world' in it and the editor will create an empty world if need be. Click on EDIT to select general editing mode. Now select a view by clicking somewhere on it. The currently selected view is bordered in yellow. In general operations are restricted to one view at a time and should you wish to swap views, you will need to select another by clicking on it first. With a 2D view selected, two co-ordinates are shown on the bottom. These are the offsets of the view and can be used to position the object where it can best be seen (e.g. centrally). Each view, including the 3D one, may be moved around. This can be done either by clicking on the arrows shown, holding down the middle mouse button over the view and moving the mouse, or clicking on one of the co-ordinates and entering the values by hand. Generally, whenever co-ordinates or angles are shown on the bottom line you can click on them and enter values manually for greater accuracy. The 3D view has three offsets (rather than just two) and these determine the position of the viewer. In general you will probably only need to alter the last (Z) parameter to move the scene further away or nearer. The other three values shown when the 3D view is selected are angles by which the scene is rotated - alter these in the usual way as required. 3. The menu LOAD - is self-explanatory. 3Ded expects there to be an Objects directory with all defined scenes therein. SAVE - saves the current set of objects in textual format in Objects. EDIT - select editing mode - use for moving, rotating, adding or deleting objects and sub-objects. POLY - select polygon mode - use for creating new polygons. ZOOM - use to zoom the 2D views. Values range from 1 to 10. CREATE - click on here to create a new (empty) object of the name given. DELETE - click on here to delete the currently selected polygon, sub-object or object. To delete a whole object you need to hold down SHIFT too, to confirm. MERGE and CLOSE - toggle the merge and closed flags for a sub-object - see previous articles for what these are for. 4. Editing an object Click on the name of the object you wish to edit with the middle button. It will appear in the four viewers - now click on a 2D view to edit. 5. Editing sub-objects Click on a scene and then on a sub-object to edit it. You can move it by dragging with the left button or delete it by clicking on DELETE. To select another click again or press CTRL S to cycle through the sub-objects. To insert a new sub-object simply drag its name with the left button to the desired spot in one of the 2D viewers. 6. Editing polygons When a sub-object is a polygon, the list of objects is replaced by a colour selector - slide the red, green and blue bars or click on a colour from the range shown to alter the shade of the selected polygon. Drag the vertices as you wish, or enter the co-ordinates by hand. The currently selected vertex is shown in yellow. Remember that BAU3D can only cope with convex polygons and no check is made in the editor to see that you have stuck to this rule! To delete the polygon click on DELETE. 7. Creating polygons Click on POLY. Then select a colour. Now click with the left button to set the vertices and finally with the right button to finish. To edit the polygon click on EDIT and continue as above. 8. Other keys At various times, certain hot-keys become available: CTRL Q and CTRL W zoom up and zoom down CTRL A and CTRL Z alter the 'other' co-ordinate in a 2D viewer to give full 3D control. 9. Unusual errors There are one or two unusual errors you should be aware of: 'Object is used elsewhere' means you have tried to delete an object which is used in a 'parent' object's definition. You will need to delete the reference from the parent object first. 'Illegal self-reference' means you have tried to include an object within itself (either directly or indirectly). This is prevented because obviously the BAU3D module would get itself in a never-ending loop trying to make sense of the scene.
