Detailed Description

This class represents shell primitives.

Remarks

A shell is a set of faces, defined by a list of shell vertices. Shells can have regular faces and holes and disjoint regions. Shell objects contain vertex data, edge data and face data. Vertex data is defined by one array that is the list of face vertices. Edge data contains arrays of edge properties such as edge color, linetype, visibility etc. Face data is defined by an array of shell faces and arrays of face properties such as face color, normals, transparency, material etc.

Member Function Documentation

addFaceVertex()

void OdGeShell::addFaceVertex ( int  nVertexIndex )

inline

Adds a face vertex with a specified index to the face array.

Parameters

nVertexIndex

[in] The index from the shell vertices array.

Definition at line 186 of file GeShell.h.

addVertex()

void OdGeShell::addVertex ( const OdGePoint3d &  vertex )

inline

Adds a vertex to the vertex array of the shell.

Parameters

vertex

[in] The vertex to be inserted.

Definition at line 152 of file GeShell.h.

draw()

void OdGeShell::draw ( OdGiGeometry &  geometry )

inline

Draws the shell using the specified vectorization context.

Parameters

geometry

[in] The vectorization context.

Definition at line 197 of file GeShell.h.

endFace()

void OdGeShell::endFace ( )

inline

Ends face assembling. Writes the number of face vertices that have been added by the addFaceVertex() method.

Definition at line 160 of file GeShell.h.

startFace()

void OdGeShell::startFace ( bool  bHole = false )

inline

Starts face assembling. Sets the face index at the start position of a new face to be added and reserves place for the number of face vertices adding -1 or 1 values: -1 if a hole face is expected and 1 for a regular face.

Parameters

bHole

[in] Indicates if a hole or regular face is expected. It's false by default.

faceNormals

OdGeVector3dArray OdGeShell::faceNormals

An array of faces normal vectors.

Definition at line 120 of file GeShell.h.

faces

OdInt32Array OdGeShell::faces

An array of integer number that defines a list of shell faces. In a face list a particular face is defined be a set of number. The first number contains the number of vertices of the face and its sign indicates if the face is a hole or a regular face: if the face is a hole then its vertices number must be negative. A hole face must be coplanar and entirely in another face (not touching edges). For example, the face array {3,0,2,4,-3,1,0,5} represents two faces. The first is a regular face that consists of three vertices: vertex 0, vertex 2, and vertex 4. The second is the hole face having three vertices: vertex 1, vertex 0, and vertex 5.
