Struct three_d::core::texture::Texture2DArray

pub struct Texture2DArray { /* private fields */ }

A array of 2D color textures that can be rendered into.

Note: DepthTest is disabled if not also writing to a DepthTarget. Use a RenderTarget to write to both color and depth.

Implementations

impl Texture2DArray

pub fn new(context: &Context, cpu_textures: &[&CpuTexture]) -> Self

Creates a new texture array from the given CpuTextures. All of the cpu textures must contain data with the same TextureDataType and the same width and height.

Note: Mip maps will not be generated for RGB16F and RGB32F format, even if mip_map_filter is specified.

pub fn new_empty<T: TextureDataType>( context: &Context, width: u32, height: u32, depth: u32, min_filter: Interpolation, mag_filter: Interpolation, mip_map_filter: Option<Interpolation>, wrap_s: Wrapping, wrap_t: Wrapping ) -> Self

Creates a new array of 2D textures.

Note: Mip maps will not be generated for RGB16F and RGB32F format, even if mip_map_filter is specified.

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

Fills the texture array with the given pixel data.

Panic

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

pub fn fill_layer<T: TextureDataType>(&mut self, layer: u32, data: &[T])

Fills the given layer in the texture array with the given pixel data.

Panic

Will panic if the layer number is bigger than the number of layers or if 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<'a>( &'a mut self, layers: &'a [u32], mip_level: Option<u32> ) -> ColorTarget<'a>

Returns a ColorTarget which can be used to clear, write to and read from the given layers and 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 depth(&self) -> u32

The number of layers.

Trait Implementations

impl Drop for Texture2DArray
