• int num_vertex - Number of vertices comprising the fan.

void addTriangleStrip ( int num_vertex ) #

Adds a triangle strip to the dynamic mesh. This method does not add vertices, rather it allocates indices, for which vertices should be then created with one of the addVertex*() methods. Indices will point to vertices starting from the current last vertex in the vertex buffer.

Arguments

• int num_vertex - Number of vertices comprising the strip.

void addTriangleQuads ( int num_quads ) #

Adds a given number of quadrilaterals to the dynamic mesh. This method does not add vertices, rather it allocates indices, for which vertices should be then created with one of the addVertex*() methods. Indices will point to vertices starting from the current last vertex in the vertex buffer.

Arguments

• int num_quads - Number of quadrilaterals to be added.

int saveState ( const Ptr<Stream> & stream ) #

Saves the current state of the dynamic mesh (vertices, indices, etc.) to the specified stream.

Saving into the stream requires creating a blob to save into. To restore the saved state the restoreState() method is used:

Arguments

• const Ptr<Stream> & stream - Stream to which the state of the dynamic mesh is to be saved.

Return value

true if the current state of the dynamic mesh is saved successfully; otherwise, false.

int restoreState ( const Ptr<Stream> & stream ) #

Restores a previously saved state of the dynamic mesh (vertices, indices, etc.) from the specified stream.

Restoring from the stream requires creating a blob to save into and saving the state using the saveState() method:

Arguments

• const Ptr<Stream> & stream - Stream from which the previously saved state of the dynamic mesh is to be loaded.

Return value

true if a previously saved state of the dynamic mesh is restored successfully; otherwise, false.
