Struct TextureSlot 

pub struct TextureSlot {
    pub texture: Option<TextureHandle>,
    pub transform: TextureTransform,
    pub channel: u8,
}

A texture slot that holds a texture reference and its UV transformation.

This is the primary way materials reference textures. Each slot can optionally contain a texture handle and UV transformation parameters.

Example

// Create a slot with a texture
let slot = TextureSlot::new(texture_handle);

// Create a slot with custom transform
let slot = TextureSlot::with_transform(texture_handle, TextureTransform {
    offset: Vec2::new(0.5, 0.0),
    rotation: 0.0,
    scale: Vec2::ONE,
});

Fields

texture: Option<TextureHandle>

The texture handle (None if no texture is assigned)

transform: TextureTransform

UV transformation applied to this texture

channel: u8

UV channel index (for meshes with multiple UV sets)

Implementations

impl TextureSlot

pub fn new(handle: TextureHandle) -> TextureSlot

Creates a new texture slot with default transform.

pub fn with_transform( handle: TextureHandle, transform: TextureTransform, ) -> TextureSlot

Creates a new texture slot with a custom transform.

pub fn compute_matrix(&self) -> Mat3Padded

Computes the UV transformation matrix (3x3).

Transform order: Translate * Rotate * Scale

The resulting matrix is in column-major order for WGSL compatibility.

pub fn is_some(&self) -> bool

pub fn is_none(&self) -> bool

pub fn set_texture(&mut self, handle: Option<TextureHandle>)

Sets the texture handle.
