The table of named colors has been compressed and moved out from Quantity_Color.cxx into Quantity_ColorTable.pxx. Quantity_NameOfColor - grayscale enumeration values have been re-ordered to fix discontinuity. Duplicating colors has been merged within enumeration: CHARTREUSE=CHARTREUSE1, GOLD=GOLD1, GREEN=GREEN1, ORANGE=ORANGE1, ORANGERED=ORANGERED1, RED=RED1, TOMATO=TOMATO1, YELLOW=YELLOW1. Added aliases to several other common colors: BLUE=BLUE1, CYAN=CYAN1, LIGHTCYAN=LIGHTCYAN1, MAGENTA=MAGENTA1. Quantity_Color class definition has been cleaned to follow OCCT coding style. Quantity_Color now stores NCollection_Vec3<float> as class field instead of separate components. Removed unused class Quantity_ColorDefinitionError. New methods Quantity_Color::Convert_LinearRGB_To_sRGB() and Quantity_Color::Convert_sRGB_To_LinearRGB() converting RGB components from linear to non-linear sRGB colorspace and vice versa. Image_PixMap::PixelColor() and Image_PixMap::SetPixelColor() methods have been extended with an optional argument for performing linearization/delinearization of 8-bit sRGB pixel formats. Draw Harness command AISColor has been corrected to take color name instead of enumeration index.

# The following example constructs (however, not trying to follow the drawings
|
|
# precisely) an airplane part called Gehause Rohteil from MBB Deutsche Aerospace.
|
|
# In this example the planar geometry is combined together with cylindrical parts.
|
|
# There are many ways to create a single mechanical workpiece like the following
|
|
# one. Here we choose Booleans as a main tool for material cutting. Fillets
|
|
# (presented in the original model) are not employed herein as we are focused
|
|
# on BOPs only. However, Gehause Rohteil is a good model to test blendings as well.
|
|
#
|
|
# This model was used as a test part for comparing modeling systems in 1979 and
|
|
# again in 1983. The tests were organized by Computer Aided Manufacturing
|
|
# International (CAM-I).
