| class | Primitive |
3D data is stored in a Scene object. The Scene contains a vector of these, each one describes a single geometric object that is shaded with a single set of shaders and transformed by a single matrix.
| GeoInfo::GeoInfo | ( | ) |
Constructor clears all the geometry lists and nulls the materials.

| void GeoInfo::validate | ( | ) |
Get primitives and attributes ready for display/rendering.
Append another GeoInfo's geometry into this one. Point data is duplicated and every primitive is copied.
Re-assign the standard attribute references from the current list.

| void GeoInfo::update_bbox | ( | ) |
Calculate axis-aligned bounding box.
Get the GeoInfo's bounding-box up-to-date by finding a bounding volume that fits around all points. Alternate bounding geometry such as spheres can be calculated at this time. Produces bounding-box by adding each point to the local bounding box.
References DD::Image::GeoInfo::Cache::bbox, DD::Image::Box3::clear(), DD::Image::Box3::expand(), matrix, DD::Image::GeoInfo::Cache::points, and DD::Image::Matrix4::transform().
| const Primitive* DD::Image::GeoInfo::primitive | ( | unsigned | n | ) | const [inline] |
Get primitive.
| void DD::Image::GeoInfo::setVertexCount | ( | int | vertices | ) | [inline] |
Allows cache vertex count to be manually overridden to keep attributes in sync with primitives. Some Primitive types do not have vertex counts that can be predicted at the moment the primitive is added to the GeoInfo leading to a difference in total vertex count causing vertex Attributes to have incorrect sizes.
| const Hash& DD::Image::GeoInfo::src_id | ( | ) | const [inline] |
Return the object ids.
| unsigned GeoInfo::size | ( | int | group | ) | const |
Returns the size of the group list.
| const Attribute * GeoInfo::get_attribute | ( | const char * | name | ) | const |
Find a valid attribute by name at each level of possible assignment in this order of importance: Vertex, Point, Material, Primitive, then Object. If found return a pointer to the Attribute, otherwise NULL.

Find a valid attribute by name at each level of possible assignment in this order of importance: Vertex, Point, Material, Primitive, then Object. If found return a pointer to the AttribContext structure which has the attribute pointer and it's group info.
