Significance of the File
File contains information about perspective, illumination, color scaling, shading
File-Contents (in Catchwords)
- basic data: fog factor, shade factor, shading steps, shading type, type of area filling (not yet used)
- observer parameters: projection, distance between observer and picture, observer location, direction of view (not yet used)
- illumination parameters / environmental light
- light sources: count, type, color, relative intensity
- material properties: count, identification number, number of color trace, coefficient of reflection, spectral reflection parameter, coefficient of transparency, structure identification
- color scheme: number of colors/classes, identification number, start and end value for the phys. property, type of scaling, characterising, start and end values HLS model.
- Optionally each color can be redefined individually in either one of the following ways:
- insert optional block (BEGINDATA, ENDDATA) redef_colors directly in file lights.dat, or
- insert optional input line REDEFCOLORFILE redef-filename, then file redef-filename contains block redef_colors with modified definitions of the individual colors.
- Remark: option 2 recilitates re-use of existing color scheme definitions.
