Detailed Description

A mesh object is a set of information on a visible geometrical object like character model, terrain or other structures and entities.

Evas 3D support key-frame-based mesh animation, so a mesh can have multiple frames and each frame has its own material and geometric data. Like other data objects, a mesh can be located on a scene by being contained in a node. The mesh is transformed from its modeling coordinate space into the node's coordinate space. Also, the frame number is saved in the containing node. So, one can locate multiple nodes having same mesh object with different animation frame and transform. Unlike camera and light object, multiple meshes can be contained in a single node.

EOAPI void evas_3d_mesh_frame_vertex_data_set	(	int	frame,
		Evas_3D_Vertex_Attrib	attrib,
		int	stride,
		const void *	data
	)

Set the vertex data of the key frame of the given mesh.

This function make evas read from the given buffer whenever it requires. If you want to release the buffer after calling this functions, use evas_3d_mesh_frame_vertex_data_copy_set() instead.

After setting the vertex data, further modifications should be protected by map/unmap pair.

Parameters

[in]	frame	The number of the key frame.
[in]	attrib	Vertex attribute ID.
[in]	stride	Stride to go to the next vertex (in bytes).
[in]	data	Pointer to the vertex data buffer.

EOAPI void evas_3d_mesh_frame_vertex_data_copy_set	(	int	frame,
		Evas_3D_Vertex_Attrib	attrib,
		int	stride,
		const void *	data
	)

Set the vertex data of the key frame of the given mesh by copying from a buffer.

This function allocates internal vertex buffer and copy from the given buffer. So you can release the buffer. If you want to modify the vertex data use evas_3d_mesh_frame_vertex_data_map(). After finishing the modifications, you should call evas_3d_mesh_frame_vertex_data_unmap().

Parameters

[in]	frame	The number of the key frame.
[in]	attrib	Vertex attribute ID.
[in]	stride	Stride to go to the next vertex (in bytes).
[in]	data	Pointer to the vertex data buffer.

EOAPI void* evas_3d_mesh_frame_vertex_data_map	(	int	frame,
		Evas_3D_Vertex_Attrib	attrib
	)

Map the vertex buffer of the key frame of the given mesh.

After manipulating the mapped buffer, evas_3d_mesh_frame_vertex_data_unmap() should be called to properly download the data to the engine. If the data was set using evas_3d_mesh_frame_vertex_data_set(), pointer to the original buffer will be returned. Otherwise, the returned pointer can differ every time calling this function.

See also: evas_3d_mesh_frame_vertex_data_unmap()

Returns: Starting address of the mapped vertex buffer.

Parameters

[in]	frame	The number of the key frame.
[in]	attrib	Vertex attribute ID.

EOAPI void evas_3d_mesh_vertex_count_set ( unsigned int count )

Set the vertex count of the given mesh.

Each key frame should have same vertex count to be properly interpolated. Key frames have their own vertex data and the data should have more vertices than the mesh's vertex count.

Default vertex count is 0.

Parameters

[in] count Vertex count.
