GeomTransformer Class Reference

An object specifically designed to transform the vertices of a Geom without disturbing indexing or affecting any other Geoms that may share the same vertex arrays, and without needlessly wasting memory when different Geoms sharing the same vertex arrays are transformed by the same amount. More...

Detailed Description

If you create a single GeomTransformer and use it to transform a number of different Geoms by various transformations, then those Geoms which happen to share the same arrays and are transformed by the same amounts will still share the same arrays as each other (but different from the original arrays).

Member Function Documentation

bool GeomTransformer::apply_state ( GeomNode * node,

const RenderState * state

)

Applies the indicated render state to all the of Geoms.
Returns true if the GeomNode was changed, false otherwise.
Definition at line 427 of file geomTransformer.cxx.

bool GeomTransformer::set_color ( GeomNode * node,

const Colorf & color

)

Overrides the color indicated within the GeomNode with the given replacement color.
Returns true if any Geom in the GeomNode was changed, false otherwise.
Definition at line 304 of file geomTransformer.cxx.
References Colorf.

bool GeomTransformer::set_color ( Geom * geom,

const Colorf & color

)

Overrides the color indicated within the Geom with the given replacement color.
Returns true if the Geom was changed, false otherwise.

bool GeomTransformer::transform_colors ( GeomNode * node,

const LVecBase4f & scale

)

Transforms the colors in all of the Geoms within the indicated GeomNode by the indicated scale.
Does not destructively change Geoms; instead, a copy will be made of each Geom to be changed, in case multiple GeomNodes reference the same Geom. Returns true if the GeomNode was changed, false otherwise.
