Struct AlphaAddress 

pub struct AlphaAddress {
    pub x: u32,
    pub y: u32,
    pub channel: u32,
    pub byte: u32,
}

Where one alpha value lives in an alpha texture: its texel, the channel within that texel, and the byte within that channel.

The shader reconstructs the same address from a strip’s col_idx with shifts and masks, using GpuConfig::alphas_tex_width_bits for the row stride.

Fields

x: u32

Texel column.

y: u32

Texel row.

channel: u32

Channel within the texel (0-3).

byte: u32

Byte within the channel (0-3).

Implementations

impl AlphaAddress

pub const fn byte_offset(self, width: u32) -> u32

The offset of this address in an upload buffer of a texture width texels wide — the inverse of alpha_address, which is what makes the packing round-trippable.
