static TypedWritable *const | Null = (TypedWritable*)0L |
A container for geometry primitives.
This class associates one or more GeomPrimitive objects with a table of vertices defined by a GeomVertexData object. All of the primitives stored in a particular Geom are drawn from the same set of vertices (each primitive uses a subset of all of the vertices in the table), and all of them must be rendered at the same time, in the same graphics state.
void Geom::add_primitive | ( | const GeomPrimitive * | primitive | ) |
Adds a new GeomPrimitive structure to the Geom object.
This specifies a particular subset of vertices that are used to define geometric primitives of the indicated type.
Don't call this in a downstream thread unless you don't mind it blowing away other changes you might have recently made in an upstream thread.

Expands min_point and max_point to include all of the vertices in the Geom, if any.
found_any is set true if any points are found. It is the caller's responsibility to initialize min_point, max_point, and found_any before calling this function.
This version of the method allows the Geom to specify an alternate vertex data table (for instance, if the vertex data has already been munged), and also allows the result to be computed in any coordinate space by specifying a transform matrix.

Copies the primitives from the indicated Geom into this one.
This does require that both Geoms contain the same fundamental type primitives, both have a compatible shade model, and both use the same GeomVertexData. Both Geoms must also be the same specific class type (i.e. if one is a GeomTextGlyph, they both must be.)
Returns true if the copy is successful, or false otherwise (because the Geoms were mismatched).

void Geom::offset_vertices | ( | const GeomVertexData * | data, |
int | offset | ||
) |
Replaces a Geom's vertex table with a new table, and simultaneously adds the indicated offset to all vertex references within the Geom's primitives.
This is intended to be used to combine multiple GeomVertexDatas from different Geoms into a single big buffer, with each Geom referencing a subset of the vertices in the buffer.

void Geom::operator= | ( | const Geom & | copy | ) |
The copy assignment operator is not pipeline-safe.
This will completely obliterate all stages of the pipeline, so don't do it for a Geom that is actively being used for rendering.

void Geom::prepare | ( | PreparedGraphicsObjects * | prepared_objects | ) |
Indicates that the geom should be enqueued to be prepared in the indicated prepared_objects at the beginning of the next frame.
This will ensure the geom is already loaded into geom memory if it is expected to be rendered soon.
Use this function instead of prepare_now() to preload geoms from a user interface standpoint.

GeomContext * Geom::prepare_now | ( | PreparedGraphicsObjects * | prepared_objects, |
GraphicsStateGuardianBase * | gsg | ||
) |
Creates a context for the geom on the particular GSG, if it does not already exist.
Returns the new (or old) GeomContext. This assumes that the GraphicsStateGuardian is the currently active rendering context and that it is ready to accept new geoms. If this is not necessarily the case, you should use prepare() instead.
Normally, this is not called directly except by the GraphicsStateGuardian; a geom does not need to be explicitly prepared by the user before it may be rendered.

This does not also test the Geom's associated GeomVertexData. That must be tested separately.

void Geom::transform_vertices | ( | const LMatrix4 & | mat | ) |
Applies the indicated transform to all of the vertices in the Geom.
If the Geom happens to share a vertex table with another Geom, this operation will duplicate the vertex table instead of breaking the other Geom; however, if multiple Geoms with shared tables are transformed by the same matrix, they will no longer share tables after the operation. Consider using the GeomTransformer if you will be applying the same transform to multiple Geoms.

void Geom::unify_in_place | ( | int | max_indices, |
bool | preserve_order | ||
) |
Unifies all of the primitives contained within this Geom into a single (or as few as possible, within the constraints of max_indices) primitive objects.
This may require decomposing the primitives if, for instance, the Geom contains both triangle strips and triangle fans.
max_indices represents the maximum number of indices that will be put in any one GeomPrimitive. If preserve_order is true, then the primitives will not be reordered during the operation, even if this results in a suboptimal result.
