- The happy part:
-
- Lv2povid.exe converts the output of Lj. Lapre's Lviewer and
- Lparser to a scene file for POVRAY v1/2, and ViVid v2.0.
-
-
- It knows a few command-line parameters :
- [1] :creates the scene file compatible with POVRAY v1.0
- [2] :creates the scene file compatible with POVRAY v2.0
- [vivid] :creates the scene file compatible with ViVid v2.0,
- see lv2povid.doc for more info.
- [x.map] :creates the scene file compatible with ViVid v2.0 OR
- PovRay v2.1, using x.map as color-height map;
- use [-crc x.map] or [-csc x.map] for central_radial_coloring or
- central_square_coloring.
- [-h] :to get 'on screen' help.
- [-v] :will print the version number of Lv2PoVid to the screen.
-
- New in this release:
- -POVRAY inc file output using multicolor .map files
- from Fractint,
-
- -Scene and object files are now separate,
- ie. Povray.inc and ViVid.vo files,
-
- -Cleared output like "1.234E-6", most
- raytracers do not like them,
-
- -The lv2povid.doc file is now separate from
- the program, the "makedoc" commandline option
- generates nothing but an error.
-
- -Povray: only v2.0/2.1 compatible file output,
- discontinued PovRay v1.0 support.
-
- -All files will now overwrite older existing files
- with the same name, no more "append" files!
-
- -Killed some other little bugs.
-
- _________________________Lparser output___________________________
-
- POVRAY compatible scene file:
-
- -To use this program for the connection between the programs:
- Lparser, Lviewer and POVRAY v2.0 you might want to use the
- following quide lines:
-
-
- First start the Lparser program from Lj. Lapre with a .ls file of
- your choice, be sure to use a small one. (try TROPISM.LS)
- To do this, type [ Lparser tropism ] (without the brackets) and
- press [Enter].
- The program creates a 'output.vol' file for you, we will use it
- later.
- Now we need to get a POVRAY compatible output of the Lparser for
- the same .ls file, so type one of the following lines and press
- [Enter].
- Lparser -v tropism
- Lparser -bc tropism
- Lparser -Bc tropism
-
- 'Feed' the output.vol to the Lviewer program by typing:
- [ Lviewer output ] and press [Enter].
- After the Lviewer has completed its STARTUP screen, press [F1].
- Now rotate, translate, zoom etc. the picture as desired, and if you
- have found a nice view, press [F1] again, and leave the Lviewer (ESC).
-
- (Lv2povid needs to have a double long info.txt file from the Lviewer
- with the starting and ending position of the camera to make the
- POVRAY view exactly the same as the view you had with the Lviewer.
- Make sure there is NO old info.txt file present!)
-
- The output.pov or output?.inc or output.inc file(s) and the info.txt
- file should be in the same directory as the Lv2povid.exe program.
- Type [Lv2povid 2] and press [Enter].
- Lv2povid will create a POVRAY v2.0 compatible scene file for you,
- called 'Lpar2pov.pov'. Rename it as desired.
- Now 'feed' it to POVRAY v2.0, then try an other one and more and more and..
-
- NEW in version 3:
- To get multicolored scenefiles from a Lparser .inc file using a .map color
- file, try the following commands: lv2povid pov-crc xxx.map
- lv2povid pov-crcr xxx.map
- Lv2povid v3 will create a multicolor scene file (lpar2pov.inc) composed of
- capped cylinders and triangles, and a scene file (lpar2pov.pov).
- (Try the map files from Fractint!)
-
-
-
- ViVid compatible scene file:
-
- -To convert Lparser output to ViVid use the same instructions as for POVRAY,
- but with the following restrictions:
- Use -vc output of the Lparser, the scene file created is made out of
- multicolor cylinders and triangles, very similar to the 'Lviewer picture'
-
- Use Lviewer to seek out a nice view angle and make the info.txt file as
- discussed for POVRAY compatible output.
- The output.inc file and the info.txt file should be in the same directory
- as Lv2povid.exe.
- Simply type [lv2povid vivid] and the scene(.v) and object(.vo) files are
- created. Feed them to ViVid.....
- It is also possible to color the object with a .map color file, use the option
- [vivid-crc x.map] for central_radial_coloring.
- Use [vivid-crcr x.map] to reverse the coloring of the object

- ______________________Fractint output_______________________________
-
- -To use this program for the connection between FracTint v18.2
- and the raytracers ViVid or POVRAY, via the great Lviewer
- from Lj.Lapre, you might want to use the following quide lines:
-
- First create an .POT file of your favourite fractal with
- inside=250, outside=iter, maxpotential=255, bailout=32500,
- 16bit=yes. (The slope factor must be seeked out for every
- single .POT file.)
- Save this .POT file to disk.
- Press [y] and set the 16bit value to [NO].
- Then choose the right color map for the image, remember that
- the colors you choose now will be used in the final POV picture.
- Save this image too, it should automatically be saved as an
- .GIF file, note the name of this file, you'll need it later.
-
- Press [3], and seek out the .POT file you just made.
- Set courseness to +/- [60], ray trace out [3], briefoutput to [yes],
- X axis to [100], Y axis to [100], surface roughness to [30].
- Press enter until FracTint starts to create the .RAY file.
- When done: leave FracTint.
-
- Load the .RAY file into the Lviewer, use the quide lines in
- the Lviewer.txt file.
- After the file is loaded into the Lviewer, press [F1], then
- seek out the view you like most and press [F1] again.
- Copy the info.txt and the .ray file to the directory of LV2POVID,
- using the following commands:
-
- [1] : to make a scene file compatible with POVRAY v1.0
-
- [2] : to make a scene file compatible with POVRAY v2.0
-
- [vivid] : to make a mono colored scene file compatible with VIVID v2.0.
- The .ray and info.txt files should be in the same directory as
- lv2povid to create the ViVid scene files (.v and .vo),
- output smooth ViVid patches.
-
- [x.map] : to make the scene file compatible with ViVid v2.0, but
- with the use of a .map file for coloring the scene,
- output smooth ViVid patches. (.v and .vo file)
- The .map format is similar to the Fractint.map files. :)
- Use for central_square/radial_coloring (from center outwards coloring)
- the options [-csc x.map] or [-crc x.map].
- Use [-cac] for central avarage coloring.
-
- After Lv2povid.exe is done, there should be a scene (.v) and a
- object (.vo) file with the same name as the .RAY file.

- Many thanks to Lj. Lapre and Martin Higgs for testing all versions,
- and the interactive feedback, that helped creating the lv2povid pgm.
