Detailed Description

the transformed vertex data of many separate objects. these objects could be separate instances of the same model or instances of many different models, the only restrictions are: the vertex formats must match they must all use the same material TODO: add a max_buffer_vertex_count, optional try_write_to_buffer, optional points to the head of the data just added to the buffer, so you can replace a section, returns nullptr if the vertex count would exceed the max

Constructor & Destructor Documentation

batch_model()

gdk::batch_model::batch_model	(	std::shared_ptr< gdk::graphics::context >	pContext,
		std::vector< vertex_data >	data
	)

rewrite a subset of model's vertex data with the buffer range specified

throw is no a_Position throw is a_Postion does not have 3 components

Member Function Documentation

write_to_buffer()

size_t gdk::batch_model::write_to_buffer	(	size_t	vertexDataIndex,
		const graphics_vector3_type &	aPos,
		const graphics_vector3_type &	aRot = {},
		const graphics_vector3_type &	aScale = {1}
	)

update buffer at location returns index into the buffer where the written data starts
