Detailed Description

Base class for an Op that produces a GeoInfo. The data is accessed by calling geometry_engine() and passing it a Scene to add a new GeoInfo to.

Member Function Documentation

void GeoOp::build_scene ( Scene & scene )

Start the geometry construction process. This would typically be called directly by a viewer, renderer or write node. If the scene's hash are different than the geo's, rebuild the scene. The output object list/cache is filled in by the GeoOp tree during the geometry_engine() call. To reduce having to constantly recalculate primitive structures, we only rebuild those geometry groups whose rebuild flag is set in the cache's rebuild_mask.

void GeoOp::get_geometry	(	Scene &	scene,

Synchronize the local cache objects with the output GeometryList. For an empty output this simply means adding objects to it, otherwise if a higher up GeoOp has already added objects we must compare our cache objects against the output objects and resolve any differences.

For each object in the local cache find the corresponding object in the output list. Rearrange, add or delete if different. Two pieces of information are needed for this: 1) The unique hash id derived from the originating GeoOp Node and the index of the object. 2) The version number, or copy number, incremented at each split. We must handle cases of an object disappearing from the output as well as new objects appearing. There are two distinct update phases we must handle: The cache being brand new and the cache already existing but objects are in a different order.

void GeoOp::delete_allocations ( GeoInfo::Cache & cache )

protected

Delete any allocated pointers in cache. You better be the owner of the cache!

void GeoOp::geometry_engine	(	Scene &	scene,
		GeometryList &	out
	)

protectedvirtual

Sub-class dependent portion of get_geometry(). This should be implemented on plugins to construct geometry. The default implementation gets the input's geometry.

Reimplemented in DD::Image::ReadGeo, DD::Image::SourceGeo, DD::Image::TransformGeo, DD::Image::ModifyGeo, and DD::Image::NullGeo.

void GeoOp::add_draw_geometry ( ViewerContext * ctx )

protected

Subclasses can call this in build_handles(). It will construct the output geometry and add callbacks to draw it in the viewer. You should only call this if ctx->connected is >= SHOW_OBJECT and should then set ctx->connected to CONNECTED before calling any inputs, so that objects are not drawn more than once. Also you must call validate(false) before this.
