|
Helper tool to access and edit [Mesh] data.
|
|
</brief_description>
|
|
<description>
|
|
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.
|
|
[codeblock]
|
|
var mesh = ArrayMesh.new()
|
|
mesh.add_surface_from_arrays(Mesh.PRIMITIVE_TRIANGLES, CubeMesh.new().get_mesh_arrays())
|
|
var mdt = MeshDataTool.new()
|
|
mdt.create_from_surface(mesh, 0)
|
|
for i in range(mdt.get_vertex_count()):
|
|
var vertex = mdt.get_vertex(i)
|
|
# In this example we extend the mesh by one unit, which results in separated faces as it is flat shaded.
|
|
vertex += mdt.get_vertex_normal(i)
|
|
# Save your change.
|
|
mdt.set_vertex(i, vertex)
|
|
mesh.surface_remove(0)
|
|
mdt.commit_to_surface(mesh)
|
|
var mi = MeshInstance.new()
|
|
mi.mesh = mesh
|
|
add_child(mi)
|
|
[/codeblock]
|
|
See also [ArrayMesh], [ImmediateGeometry] and [SurfaceTool] for procedural geometry generation.
