Descriptor of a texture that is used to request textures from a graphics server.

Fields

kind: GpuTextureKind

Kind of the texture. See GpuTextureKind docs for more info.

pixel_kind: PixelKind

Pixel kind of the texture. See PixelKind docs for more info.

min_filter: MinificationFilter

Minification filter of the texture. See MinificationFilter docs for more info.

mag_filter: MagnificationFilter

Magnification filter of the texture. See MagnificationFilter docs for more info.

mip_count: usize

Total number of mips in the texture. Texture data must contain at least this number of mips.

s_wrap_mode: WrapMode

S coordinate wrap mode. See WrapMode docs for more info.

t_wrap_mode: WrapMode

T coordinate wrap mode. See WrapMode docs for more info.

r_wrap_mode: WrapMode

R coordinate wrap mode. See WrapMode docs for more info.

anisotropy: f32

Anisotropy level of the texture. Default is 1.0. Max number is usually depends on the GPU, but the cap is 16.0 on pretty much any platform. This number should be a power of two.

data: Option<&'a [u8]>

Optional data of the texture. If present, then the total number of bytes must match the required number of bytes defined by the texture kind, pixel kind, mip count.

base_level: usize

Specifies the index of the lowest defined mipmap level. Keep in mind, that the texture data should provide the actual mip map level defined by the provided value, otherwise the rendering will be incorrect (probably just black on majority of implementations) and glitchy.

max_level: usize

Sets the index of the highest defined mipmap level. Keep in mind, that the texture data should provide the actual mip map level defined by the provided value, otherwise the rendering will be incorrect (probably just black on majority of implementations) and glitchy.

min_lod: f32

Sets the minimum level-of-detail parameter. This floating-point value limits the selection of highest resolution mipmap (lowest mipmap level). The initial value is -1000.0.

max_lod: f32

Sets the maximum level-of-detail parameter. This floating-point value limits the selection of the lowest resolution mipmap (highest mipmap level). The initial value is 1000.0.

lod_bias: f32

Specifies a fixed bias value that is to be added to the level-of-detail parameter for the texture before texture sampling. The specified value is added to the shader-supplied bias value (if any) and subsequently clamped into the implementation-defined range −bias_max..bias_max, where bias_max is the value that can be fetched from the current graphics server. The initial value is 0.0.

Trait Implementations

impl Default for GpuTextureDescriptor<'_>

fn default() -> GpuTextureDescriptor<'_>

Returns the “default value” for a type.
