Struct Texture2DRef 

pub struct Texture2DRef {
    pub texture: Arc<Texture2D>,
    pub transformation: Mat3,
}

A reference to a 2D texture and a texture transformation.

Fields

texture: Arc<Texture2D>

A reference to the texture.

transformation: Mat3

A transformation applied to the uv coordinates before reading a texel value at those uv coordinates. This is primarily used in relation to texture atlasing.

Implementations

impl Texture2DRef

pub fn from_cpu_texture(context: &Context, cpu_texture: &CpuTexture) -> Self

Creates a new Texture2DRef with an identity transformation from a CpuTexture.

pub fn from_texture(texture: Texture2D) -> Self

Creates a new Texture2DRef with an identity transformation from a Texture2D.

Methods from Deref<Target = Texture2D>

pub fn fill<T: TextureDataType>(&self, data: &[T])

Fills this texture with the given data and generate mip maps if specified at construction.

Panic

Will panic if the length of the data does not correspond to the width, height and format specified at construction. It is therefore necessary to create a new texture if the texture size or format has changed.

pub fn as_color_target(&self, mip_level: Option<u32>) -> ColorTarget<'_>

Returns a ColorTarget which can be used to clear, write to and read from the given mip level of this texture. Combine this together with a DepthTarget with RenderTarget::new to be able to write to both a depth and color target at the same time. If None is specified as the mip level, the 0 level mip level is used and mip maps are generated after a write operation if a mip map filter is specified. Otherwise, the given mip level is used and no mip maps are generated.

Note: DepthTest is disabled if not also writing to a depth texture.

pub fn width(&self) -> u32

The width of this texture.

pub fn height(&self) -> u32

The height of this texture.

pub fn number_of_mip_maps(&self) -> u32

The number of mip maps of this texture.
