Struct ModelTransformBuffer 

pub struct ModelTransformBuffer(/* private fields */);

The model transformation buffer.

This buffer holds the model transformation data, including position, rotation, and scale. It is used to transform the model from model space to world space.

Implementations

impl ModelTransformBuffer

pub fn new(device: &Device) -> Self

Create a new model transformation buffer.

pub fn update(&self, queue: &Queue, pos: Vec3, rot: Quat, scale: Vec3)

Update the model transformation buffer.

pub fn update_with_pod(&self, queue: &Queue, pod: &ModelTransformPod)

Update the model transformation buffer with ModelTransformPod.
