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
