STLA_DISPLAY
Display an ASCII STL 3D Graphics File

STLA_DISPLAY is an executable MATLAB program which gets the name of an ASCII STL (Stereolithography) file from the user, reads the 3D graphics information stored in the file, and displays the structure on the screen.

Source Code:

• ch_cap.m capitalizes a character.
• ch_eqi.m case-insensitive comparison of two characters.
• ch_is_digit.m is true if a character represents a digit.
• ch_to_digit.m converts a character to the digit it represents.
• s_cat.m concatenates two strings to make a third string.
• s_eqi.m is a case insensitive comparison of two strings for equality.
• s_escape_tex.m de-escapes TeX escape sequences.
• s_len_trim.m returns the length of a string to the last nonblank.
• s_to_r8.m reads an R8 from a string.
• stla_display.m gets the name of an ASCII STL file from the user, reads the file, and displays it on the screen.
• stla_read.m reads graphics information from an ASCII StereoLithography file.
• stla_size.m determines sizes associated with an STLA file.
• stla_size_print.m prints sizes associated with an STLA file.
• timestamp.m prints the current YMDHMS date as a time stamp.
• word_next_read.m "reads" words from a string, one at a time.

Examples and Tests:

• block100.stla, an STLA file (12 faces) that describes a cube of side 100.
• block100.png, a PNG image of the shape when displayed by STLA_DISPLAY.
• bottle.stla, an STLA file (1240 faces) that describes a bottle.
• bottle.png, a PNG image of the shape when displayed by STLA_DISPLAY.
• cube.stla, a simple STLA file (12 faces) that describes a cube.
• cube.png, a PNG image of the shape when displayed by STLA_DISPLAY.
• humanoid_tri.stla, an STLA file (96 faces) that describes a humanoid.
