Detailed Description

A mesh composed from other meshes.

A composite_mesh object is simply a collection of other d3d_mesh objects. It can be used to group up objects together or simply have one representative for many loaded meshes.

This is not a scenegraph node!

Member Function Documentation

void dune::composite_mesh::create_from_dir	(	ID3D11Device *	device,
		const tstring &	pattern
	)

Create a composite_mesh from a filename pattern.

Calling this function will search a directory for a pattern and load all hits into as separate meshes to group them up in a composite_mesh.

Parameters

device	The Direct3D device.
pattern	A string representing a file pattern, e.g. C:/models/*.obj.

References create(), dune::extract_path(), and dune::make_absolute_path().

void dune::composite_mesh::render ( ID3D11DeviceContext *  context, DirectX::XMFLOAT4X4 *  to_clip = nullptr  )

virtual

Renders the mesh using the shaders previously set.

When calling render, the mesh will be rendered using the shaders set with set_shaders(). Additionally, a clip-space matrix can be set to clip away unseen geometry.

Parameters

context	A Direct3D context.
to_clip	A clip-space matrix against which the mesh is being culled.

Implements dune::d3d_mesh.
