void Namable::output (  ostream &  out  )  const [inline, inherited]
 

Outputs the Namable.

This function simply writes the name to the output stream; most Namable derivatives will probably redefine this.

Sets the flag indicating whether vertices will be generated with UV's or not.

void CardMaker::set_source_geometry (  PandaNode *  node,
const LVecBase4f &  frame
)  [inline]
 

Sets a node that will be copied (and scaled and translated) to generate the frame, instead of generating a new polygon.

The node may contain arbitrary geometry that describes a flat polygon contained within the indicated left, right, bottom, top frame.

When generate() is called, the geometry in this node will be scaled and translated appropriately to give it the size and aspect ratio specified by set_frame().

Definition at line 165 of file cardMaker.I.

void CardMaker::set_uv_range (  const TexCoordf &  ll,
const TexCoordf &  ur
)  [inline]
 

Sets the range of UV's that will be applied to the vertices.

If set_has_uvs() is true (as it is by default), the vertices will be generated with the indicated range of UV's, which will be useful if a texture is applied.
