Detailed Description

Contains a list of points and geometric primitives.

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.

Constructor & Destructor Documentation

DD::Image::GeoInfo::GeoInfo ( )

Constructor clears all the geometry lists and nulls the materials.

Member Function Documentation

void DD::Image::GeoInfo::copy ( const GeoInfo b)

Point data is duplicated and a shallow copy of primitive data is made.

void DD::Image::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.

Referenced by DD::Image::GeoOp::build_scene(), DD::Image::Scene::generate_render_primitives(), DD::Image::ModifyGeo::geometry_engine(), and DD::Image::Scene::validate().

void DD::Image::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.

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 DD::Image::GeoInfo::size ( int  group) const

Returns the size of the group list.

const Attribute* DD::Image::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.

const Attribute* DD::Image::GeoInfo::get_typed_attribute ( const char *  name,
int  type 
) const

Search for an attribute by name and type, returning its pointer if found.

const Attribute* DD::Image::GeoInfo::get_group_attribute ( int  group,
const char *  name 
) const

Search for an attribute by name and group, returning its pointer if found.

Referenced by DD::Image::Render::_request().

const Attribute* DD::Image::GeoInfo::get_typed_group_attribute ( int  group,
const char *  name,
int  type 
) const

Search for an attribute by name, group and type, returning its pointer if found.

const AttribContext* DD::Image::GeoInfo::get_attribcontext ( 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 AttribContext structure which has the attribute pointer and it's group info.

const AttribContext* DD::Image::GeoInfo::get_typed_attribcontext ( const char *  name,
int  type 
) const

Search for an attribute by name and type and return a const reference to it if found.

const AttribContext* DD::Image::GeoInfo::get_group_attribcontext ( int  group,
const char *  name 
) const

Search for an attribute by name and group and return a const reference to it if found.

const AttribContext* DD::Image::GeoInfo::get_typed_group_attribcontext ( int  group,
const char *  name,
int  type 
) const

Search for an attribute by name, group and type, returning its pointer if found.

void DD::Image::GeoInfo::delete_group_attribute ( int  group,
const char *  name,
int  type = INVALID_ATTRIB 
)

Clears the reference pointer to the attribute, effectively deleting it.

bool DD::Image::GeoInfo::orient_normals ( int  group,
Attribute ,
const Vector3 P,
bool  invert = false 
) const

Point the normals of the passed in attribute at point Pl. Returns true if successful.

void DD::Image::GeoInfo::draw ( ViewerContext )

Draw the GeoInfo's geometry in OpenGL.

void DD::Image::GeoInfo::draw_bbox ( ViewerContext )

Draw the surrounding bbox. This is drawn separately from the object primitives because the bbox has already been transformed by the matrix.

bool DD::Image::GeoInfo::draw_wireframe ( ViewerContext )

Draw wireframe of the object, by calling draw_wireframe on all the primitives. This compiles an OpenGL call list, which is reused until invalidate() is called. Returns false if there is some problem creating the call list (though everything ignores this)

bool DD::Image::GeoInfo::draw_solid ( ViewerContext )

Draw shaded version the object, by calling draw_solid on all the primitives. This compiles an OpenGL call list, which is reused until invalidate() is called. Returns false if there is some problem creating the call list (though everything ignores this)

Referenced by DD::Image::Black::shade_GL().

bool DD::Image::GeoInfo::draw_pick_ids ( ViewerContext ctx,
unsigned int  offset 
)

Draw selectable parts of the object. This compiles an OpenGL call list, which is reused until invalidate() is called. Returns false if there is some problem creating the call list (though everything ignores this).

bool DD::Image::GeoInfo::draw_selected_items ( ViewerContext ctx,
const GeoSelection &  selection 
)

Draw selected parts of the object. This compiles an OpenGL call list, which is reused until invalidate() is called. Returns false if there is some problem creating the call list (though everything ignores this).

void DD::Image::GeoInfo::print_info ( std::ostream &  o)

Primary use is to print GeoInfo information into Nuke's info box.

Referenced by DD::Image::GeoOp::print_info().
