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.

TopModel (version 1.00) main features:
--------------------------------------
� deals with polygons, bezier curves, bezier surfaces and spheres.
� real-time bezier surfaces and spheres manipulation of
unique easiness, with full control over U and V parameters for shading.
� real-time operations with all of the tools: no preview!
� powerful graphic engine supporting wireframe (uniform and shaded), uniform
fill, Gouraud and Phong shading, with texture mapping and transparency, and
a true-colour mode (that deals with several light sources and materials)
for a fast high-quality rendering.
� scene editor is not separated from object editor, thanks to the working
speed of TopModel: you can always see what you're doing.
� a unique easiness of use allowing a full control over operations.
� a powerful navigation tool.
� object points and control points of surfaces are always editable, even on
the whole scene: you can work on complete objects and with parts of them
at the same time.
� tools to move, rotate, magnify, copy, delete, group and un group objects.
� up to 16 paths, each composed by up to 10 bezier-curves,
used for copy, extrusion and deformation.
� copy tool, working with steps (in rotation and in movement) or along a
multi-bezier path (with or without rotation).
� powerful and professional sweep tool (with control over altitude, envelope
on current plane and envelope on current axis).
� powerful and professional extrusion tool on a multi-bezier path (with
control over altitude, envelope and bevelling).
� deformation tool (with control over torsion, envelope on
the current plane and altitude).
� magnetic tool with control parameters.
� simmetry tool useful during many drag operations.
� two real-time lattice deformation tools using:
a bounding-box cube (tri-linear deformation tool);
a bezier-volume (bezier's volume distorsion with a powerful control on
objects, also allowing a non-linear internal expansion).
� texture mapping (one texture per object, planar, cylindrical or spherical)
with control over tiling, offset and rotation and with or without mask.
� bitmap textures up to 32bpp in all the formats recognised by !ChangeFSI.
References of used textures in the saved file.
� subdivison tool, to split objects in smaller units.
� space out, align and pack objects tool for better control.
� join and split points tool to create nets of objects (and to reduce the
number of points).
� possibility to set (and recall) up to 64 named views.
� up to 2048 named groups.
� up to 1024 light sources of any type and colour plus a front light and
an ambiental light.
� object-oriented management of materials and colours with industry-standard
pre-settings.
� real-time grid, visible in axonometric or perspective modes, rotating with
viewpoint.
� imports TopModel binary and ASCII formats, Render Bender II, GEO, DXF and
3DStudio files.
� exports TopModel binary and ASCII formats, Draw, Sprites, Clear and PovRay
file formats.
� imports sprite files: TopModel creates one polygon for each pixel of the
source image. Dragging sprites while pressing Shift creates altitude maps,
mountains, landscapes or bas-relief from coloured sprites.
� imports draw files, with the possibility of fill and extrude them.
� an easy to read and modify ASCII file format, to let you create objects by
writing exact values.
� drag-and-drop library objects.
� highly optimized hand-written ARM code for *vey* high speed.
� 24bpp high quality output: TopModel uses 96 bits/pixel that are translated
into a 24bpp dithered output (typical time for a high quality 800x600 24bbp
output with several light sources, and an exact material matching on a Risc
PC600: 5 seconds).
� works on any RISC-OS 3.xx system with at least 2MB RAM (4Mb strongly
recommended).
� works in any 16 or 256 colours mode (multi-sync or VGA monitors strongly
recommended to use square-pixels modes).
The real power of TopModel does not lay in its speed during redraw (which is
very fast) but in the easiness of use and in the way you can work during
creation and editing of objects.
