DesignBlock represents a geometric block in 3D space.

Arguments

• nodes: A vector of nodes (or points) inside the block, each represented by a [f64; 3] array.
• length: The lengths of the block in the x, y, and z directions as a [f64; 3] array.
• centre: The coordinates of the center of the block as a [f64; 3] array.
• theta: The angles (in radians) to rotate the block around the x, y, and z axes as a [f64; 3] array.
• resolution: The resolution of the block in each dimension, represented as a [usize; 3] array.
• corner_nodes: The 8 corner in x, y, and z directions as a [[f64; 3]; 8] array.
• scaling_factors: The scaling factors in x, y, and z directions as a [f64; 3] array.
• local_coordinate_system: A 4x3 array defining the local coordinate system of the block.

Implementations

impl DesignBlock

pub fn new( length: [f64; 3], centre: [f64; 3], theta: [f64; 3], resolution: [usize; 3], ) -> Result<Self>

Creates a new DesignBlock instance.

Arguments

• length: The lengths of the block in the x, y, and z directions as a [f64; 3] array.
• centre: The coordinates of the center of the block as a [f64; 3] array.
• theta: The angles (in radians) to rotate the block around the x, y, and z axes as a [f64; 3] array.
• resolution: The resolution of the block in each dimension, represented as a [usize; 3] array.

Returns

A new instance of DesignBlock.

pub fn select_free_design_nodes( &self, target_mesh: &Mesh, fixed_layers: Option<usize>, ) -> Result<Vec<usize>>

Selects free deformable control nodes by checking intersection with a mesh body.

Arguments

• target_mesh: Mesh to check intersections with.
• fixed_layers: How many layers to exclude from the intersection, for instance quadratic=2, linear=1.

Returns

Node ids corresponding to free deformable DesignBlock nodes.

pub fn select_mesh_nodes_inside( &self, target_mesh_nodes: &[[f64; 3]], ) -> Result<Vec<usize>>

Selects the node ids corresponding to the target mesh that fit inside the design block.

Arguments

• target_mesh_nodes: Mesh nodes to check.

Returns

Node ids corresponding to free deformable Mesh nodes.

pub fn transform_subset( &self, node_ids: &[usize], transform_matrix: &[[f64; 4]; 4], pivot: &[f64; 3], ) -> Vec<[f64; 3]>

Creates a new set of nodes by applying a transformation to a subset of the original nodes.

Arguments

• node_ids: A slice of indices corresponding to the control points to be transformed.
• transform_matrix: The 4x4 affine transformation matrix to apply.
• pivot: The point around which the transformation (like rotation) should occur.

Returns

A new Vec<[f64; 3]> containing the full set of nodes with the specified subset transformed.
