Struct rend3_types::Skeleton

pub struct Skeleton {
    pub joint_matrices: Vec<Mat4>,
    pub mesh: MeshHandle,
}

A Skeleton stores the necessary data to do vertex skinning for an Object.

Fields

joint_matrices: Vec<Mat4>

Stores one transformation matrix for each joint. These are the transformations that will be applied to the vertices affected by the corresponding joint. Not to be confused with the transform matrix of the joint itself.

The Skeleton::form_joint_transforms constructor can be used to create a Skeleton with the joint transform matrices instead.

mesh: MeshHandle

Implementations

impl Skeleton

pub fn from_joint_transforms(
    mesh: MeshHandle,
    joint_global_transforms: &[Mat4],
    inverse_bind_transforms: &[Mat4]
) -> Skeleton

Creates a skeleton with the list of global transforms and inverse bind transforms for each joint

pub fn compute_joint_matrices(
    joint_global_transforms: &[Mat4],
    inverse_bind_transforms: &[Mat4]
) -> Vec<Mat4>

Given a list of joint global positions and another one with inverse bind matrices, multiplies them together to return the list of joint matrices.
