textures
hi to all,
i am trying to find a functionality in the dwg library for assigning a texture to an object. i have explored the odavematerial class, but it is used only for materials.
any ideas?
thanks in advance
hi,
odavematerial class can keep an image as well.
you can attach a material to object by odavematerial::attachtoobject() method.
to define how material is mapped onto object (texture mapping) acad uses ave_entity_material xdata of object. at the moment dd does not provide separate interface for mapping xdata. as workaround you can use oddbobject::xdata()/setxdata() methods (with "ave_entity_material" as regapp name) to define mapping attributes.

thank you for the reply.
is there any documentation on what needs to go into the xdata i.e. how do i define/what is the syntax for the mapping attributes? i just need a simple planar mapping to stretch a texture over a surface.
