MeshDataTool provides access to individual vertices in a [Mesh]. It allows users to read and edit vertex data of meshes. It also creates an array of faces and edges.
To use MeshDataTool, load a mesh with [method create_from_surface]. When you are finished editing the data commit the data to a mesh with [method commit_to_surface].
Below is an example of how MeshDataTool may be used.
2018-10-11 12:28:04 +08:00
[codeblock]
var mdt = MeshDataTool.new()
mdt.create_from_surface(mesh, 0)
for i in range(mdt.get_vertex_count()):
2018-12-14 16:37:19 +08:00
var vertex = mdt.get_vertex(i)
...
mdt.set_vertex(i, vertex)
2018-10-11 12:28:04 +08:00
mesh.surface_remove(0)
mdt.commit_to_surface(mesh)
[/codeblock]
