Bug reports for POV-Ray 1.0
---------------------------

This file contains reported bugs and workarounds at this point.





BUG #1: Material map orientation vector is not properly initialized.
--------------------------------------------------------------------

Example:
   material_map{gif "povmap.gif"} // doesn't work.

   material_map{<1 -1 0> gif "povmap.gif"} //works

Work-around:
   Always add "<1 -1 0>" to material_map statements.

Program fix:
   In PARSE.C line 1559...

    Make_Vector (&Texture->Texture_Gradient, 1.0, -1.0, 0.0);

 change to...

    Make_Vector (&Texture->Material_Image->Image_Gradient, 1.0, -1.0, 0.0);




BUG #2: Material map map type setting trashes memory.
-----------------------------------------------------

Example:
   material_map{ 1 <1 -1 0> gif "povmap.gif"} // doesn't work.

   material_map{<1 -1 0> gif "povmap.gif" map_type 1} //works

Work-around:
   Never use old style map type with material_map.  Always use
   the "map_type #" instead.

Program fix:
   In PARSE.C line 1570...

    (Texture->Image->Map_Type) = (int) Parse_Float ();

 change to...

    (Texture->Material_Image->Map_Type) = (int) Parse_Float ()






BUG #3: Float identifier doesn't work in old style map type setting
        for image_map, bump_map or material_map.
-------------------------------------------------------------------

Example:
  image_map{ Sphere_Map gif "rough.gif"} // doesn't work.

  image_map{ 1 gif "rough.gif"} // works.

  image_map{gif "rough.gif" map_type Sphere_Map } // works.

Work-around:
   Use either option shown above.

Program fix:
   In PARSE.C lines 1173, 1476 and 1568...

    CASE3 (DASH_TOKEN, PLUS_TOKEN, FLOAT_TOKEN)

 change to...

    CASE4 (DASH_TOKEN, PLUS_TOKEN, FLOAT_TOKEN, IDENTIFIER_TOKEN)
