This function is called by the BamReader's factory when a new object of type ColorAttrib is encountered in the Bam file. |

int ColorAttrib::compare_to_impl | ( | const RenderAttrib * | other | ) | const [protected, virtual] |
Intended to be overridden by derived ColorAttrib types to return a unique number indicating whether this ColorAttrib is equivalent to the other one.
This should return 0 if the two ColorAttrib objects are equivalent, a number less than zero if this one should be sorted before the other one, and a number greater than zero otherwise.
This will only be called with two ColorAttrib objects whose get_type() functions return the same.

const Colorf & ColorAttrib::get_color | ( | ) | const [inline] |
If the type is T_flat or T_off, this returns the color that will be applied to geometry.
If the type is T_vertex, this is meaningless.

ColorAttrib::Type ColorAttrib::get_color_type | ( | ) | const [inline] |
Returns the type of color specified by this ColorAttrib.
The options are:
T_vertex - use the vertex color specified in the geometry itself.
T_flat - use the color specified in this ColorAttrib for all geometry. You can get this color via get_color().
T_off - use the color white.

TypedWritable * ColorAttrib::make_from_bam | ( | const FactoryParams & | params | ) | [static, protected] |
This function is called by the BamReader's factory when a new object of type ColorAttrib is encountered in the Bam file.
It should create the ColorAttrib and extract its information from the file.
