-
- DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
- _c_o_r_a_l generates and graphically displays a rising aggregate
- of particles in simulation of something like 2-D coral
- growth.
-
- OOOOPPPPTTTTIIIIOOOONNNNSSSS
- -R Indicates the display will be in the root window. In
- this mode, the default color map will be used and
- no spinning of the color wheel is possible.
-
- -c _n Selects one of many different color wheels to use.
- The default color wheel is a rainbow palette.
-
- -d Indicates demo mode. In this mode, the aggregate
- will be calculated, displayed, spun, then the
- program will exit.
-
- -w _n Specifies the width of the window. Default is 512.
-
- -h _n Specifies the height of the window. Default is 512.
-
- -k _d_u_r_a_t_i_o_n
- Specifies the number of points to compute before
- changing colors. Default is number of seeds times
- number of colors.
-
- -m _n Specifies the minimum color index to be used for the
- upper end of the color wheel
-
- -n _n_u_m_p_i_c_s
- Specifies how many aggregates to compute before
- exiting. During display (see NOTES below), pressing
- 'n' or 'N' will skip to the next map.
-
- -o _f_i_l_e_n_a_m_e
- Specifies the output filename to be used. If the -o
- option is given, this file will automatically be
- written out at the completion of the drawing. If it
- is not specified, a default filename of coral.ppm is
- used and only written if the 'f' or 'F' keys are
- pressed during a run. The format of the output file
- is PPM. The parameters used to calculate the picture
- are included as comments at the beginning of the
- output file.

-
- -s Indicates to spin the color wheel immediately upon
- completion of display.
-
- -u Produces a usage message.
-
- During display, use of the keys +-_d_D_f_F_n_N_S_R_r_s_w_W_X?_h_q_Q
- indicates:
-
- (+) Increment minimum color index.
- (+) Decrement minimum color index.
- (n or N) Skip to the next aggregate.
- (s) Spin the color wheel in the positive direction.
- (r) Spin the color wheel in the negative direction.
- (R or S) Stop color wheel spinning.
- (W or w) Increment or decrement the color map index.
- (X) Erase current coral growth and start over with new
- seeds.
- (Q or q) quit

- The algorithm, which uses a modified random walk, was
- derived from lectures given by Dietmar Saupe at the
- University of California at Santa Cruz. Assistance with
- colormaps and spinning color wheels and X was gleaned from
- Hiram Clawson and Stacey Campbell.
