Polygon Class

Members

---

static PolygonPtr create ( ) #

Constructor. Initializes the polygon.

void clear ( ) #

Clears the data (vertices and indices) of the polygon.

bool createConvex ( const vec3* v, int num_vertex, const vec3& normal ) #

Creates the convex polygon.

Arguments

• const vec3* v - Pointer to an array of vertices.
• int num_vertex - Number of vertices.
  Notice

  Must be greater than or equal to 3.
• const vec3& normal - Normal of the polygon.

Return value

true if the convex polygon was successfully created; otherwise false.

bool createConvex ( const Vector<vec3>& v, const vec3& normal ) #

Creates the convex polygon.

Arguments

• const Vector<vec3>& v - Vector of polygon vertices.
• const vec3& normal - Normal of the polygon.

Return value

true if the convex polygon was successfully created; otherwise false.

bool createConcave ( const vec3* v, int num_vertex, const vec3& normal ) #

Creates the concave polygon.

Arguments

• const vec3* v - Pointer to an array of vertices.
• int num_vertex - Number of vertices.
  Notice

  Must be greater than or equal to 3.
• const vec3& normal - Normal of the polygon.

Return value

true if the concave polygon was successfully created; otherwise false.

bool createConcave ( const Vector<vec3>& v, const vec3& normal ) #

Creates the concave polygon.

Arguments

• const Vector<vec3>& v - Vector of polygon vertices.
• const vec3& normal - Normal of the polygon.

Return value

true if the concave polygon was successfully created; otherwise false.

int getNumVertex ( ) const#

Returns the number of vertices.

Return value

Number of vertices.

const vec3 & getVertex ( int num ) const#

Returns the vertex with the given number.

Arguments

• int num - Number of the vertex.

Return value

Resulting vertex.

int getVertexIndex ( int num ) const#

Returns the index of the vertex with the given number.

Arguments

• int num - Number of the vertex.

Return value

Index of the vertex.

int getNumIndices ( ) const#

Returns the number of indices.

Return value

Number of indices.

int getIndex ( int num ) const#

Returns the index with a given number.

Arguments

• int num - Number of the index.

Return value

Resulting index.
