InvTransformBuffer

Struct InvTransformBuffer 

Source
pub struct InvTransformBuffer(/* private fields */);
Expand description

An inverse transform uniform buffer for selection operations.

This buffer holds the inverse of the combined scale, rotation, and translation transform, which is used for SelectionBundle::create_sphere_bundle and SelectionBundle::create_box_bundle, but can also be used for your custom selection operations.

Implementations§

impl InvTransformBuffer

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

Create a new inverse transform buffer.
