- Sphere V2.01
- ============
-
- A program to convert a rectangular world map into a sphere.
-
-
- Introduction
- ------------
-
- Sphere allows you to load in any IFF picture (presumably a map), and will
- convert the map into one of a number of different shapes or views. It is
- possibile to view the map from the side, from the north or south poles, and
- create other unusual views.
-
-
- Requirements
- ------------
-
- Although not tested, this program should hopefully work on all Amigas. It
- was written on an Amiga 1200 with 2MB RAM and 60MB HD. The program
- requires "mathtrans.library" to be in the LIBS: directory.
-
-
- Menus
- -----
-
- The program is controlled with standard pull-down menus.
-
-
- o Project Menu
-
- Load Map - Will load an IFF picture. Pictures must be at least 320 x 200
- and may have a maximum size of 640 x 512. Any number of colours (up to
- 256) is allowed. There is a 320 x 200 world map (with 4 colours) included
- in the Sphere drawer called "Sphere.WorldMap". It was drawn freehand by
- myself and therefore is not totally accurate.
-
- Show Map/Show Creation - Will toggle between the IFF map, and the view that
- has been created in the Create menu.
-
- Save Creation - Will save the current creation as an IFF ILBM file.
-
-
- o Create Menu
-
- The options in this menu will create a new view of the world. The options
- available are:
-
- "Sphere" - Creates the usual view of the world - a globe.
-
- "Stretched" - This will produce a stretched sphere enabling the whole
- surface to be visible at once.
-
- "Diamond" - This produces a diamond shaped map and has no practical use.
-
- "North Pole" & "South Pole" - Create spheres as viewed from above and
- below.
-
- The creating and drawing process can be stopped by pressing the "Esc" key.
-
-
- o Point Menu
-
- Points are marked by clicking with the left mouse button on the map. A
- small square marker will appear.
-
- "Set Centre" - This will set the centre of the map to be at the currently
- marked point. When you next create a sphere, it will be centred at this
- point.
-
- "Set Point A" (and B) - These two options allow you define two points.
- "Distance AB" will then calculate the distance between points A and B,
- using the quickest route along the curved surface of the sphere. "Set
- Diameter" allows you to define the sphere's (planet's) diameter. The
- default Diameter is set to that of the Earth.
