Struct DownsamplingConstants 

#[repr(C)]
pub struct DownsamplingConstants {
    pub mips: u32,
    pub inverse_input_size: Vec2,
    pub _padding: u32,
}

Constants for the single-pass downsampling shader generated on the CPU and read on the GPU.

These constants are stored within a uniform buffer. There’s one such uniform buffer per image.

Fields

mips: u32

The number of mip levels that this image possesses.

inverse_input_size: Vec2

The reciprocal of the size of the first mipmap level for this texture.

_padding: u32

Padding.
