Member Function Documentation

std::size_t Dali::Geometry::AddVertexBuffer ( PropertyBuffer vertexBuffer)

Adds a PropertyBuffer to be used as source of geometry vertices.

Since:
3.0, DALi version 1.1.43
Parameters:
[in]vertexBufferPropertyBuffer to be used as source of geometry vertices
Returns:
Index of the newly added buffer, can be used with RemoveVertexBuffer to remove this buffer if no longer required
static Geometry Dali::Geometry::DownCast ( BaseHandle  handle) [static]

Downcasts to a geometry. If not, the returned handle is left uninitialized.

Since:
3.0, DALi version 1.1.43
Parameters:
