Detailed Description
Indicates what color should be applied to renderable geometry.
Definition at line 27 of file colorAttrib.h.
Member Function Documentation
◆ register_with_read_factory()
|
static |
Tells the BamReader how to create objects of type ColorAttrib.
Definition at line 163 of file colorAttrib.cxx.
References BamReader::get_factory(), and Factory< Type >::register_factory().
Referenced by init_libpgraph().
◆ write_datagram()
Writes the contents of this object to the datagram for shipping out to a Bam file.
Reimplemented from RenderAttrib.
Definition at line 172 of file colorAttrib.cxx.
References Datagram::add_int8(), and RenderAttrib::write_datagram().
Member Data Documentation
◆ get_color
|
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.
Definition at line 47 of file colorAttrib.h.
Referenced by GraphicsStateGuardian::do_issue_color().
◆ get_color_type
|
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.
