I have uploaded to SIMTEL20:
pd1:<msdos.plot>
RK-PLOT.ZIP Renders z=f(x,y) plot with hidden line removal
PLOT provides 4 complete modules rendering a function
z = f(x,y) , [xmin <= x <= xmax, ymin <= y <= ymax]
with different methods of hiddenline removal (painter's
algorithm, floating-horizon-algoritm). The z-values must
belong to a grid with equidistant in each direction nodes
and must be given in a matrix.
The type of the projection and all viewing parameters may
be altered by the user. The source code of an example
demonstrates the usage of the modules und gives starting
values of the parameters.
The sources are written in Turbo-Pascal ( you need a version
later then 4.0 ), routines critical in time use assembler
code.
