Struct GpuImageQuad 

pub struct GpuImageQuad {
    pub corners: [[f32; 3]; 4],
    pub image: usize,
    pub tint: [f32; 4],
    pub depth_test: bool,
    pub alpha_cutoff: f32,
}

A world-space 2D image-sprite quad for GpuRenderer::draw_images_deferred. corners are the four world points TL, TR, BL, BR (UVs (0,0) (1,0) (0,1) (1,1)); image indexes a texture uploaded via GpuRenderer::upload_image; tint is straight RGBA in 0..=1 (multiplied into every texel); depth_test occludes the quad behind nearer marched geometry. The facade resolves orientation + back-face culling, so this is pure geometry.

Fields

corners: [[f32; 3]; 4]

The four world-space corner points in TL, TR, BL, BR order (voxel units), mapping to UVs (0,0) (1,0) (0,1) (1,1). Need not be planar-axis-aligned; the quad is split into two perspective-correct triangles.

image: usize

Texture handle returned by GpuRenderer::upload_image. Quads referencing an id that was never uploaded are skipped.

tint: [f32; 4]

Straight RGBA multiplier 0..=1 applied to every texel ([1.0; 4] = untinted); the combined alpha drives the over-blend.

depth_test: bool

true ⇒ fragments behind nearer marched scene geometry are discarded; false ⇒ always drawn on top.

alpha_cutoff: f32

Texels with alpha below this (0..=1) are discarded in the FS. 0.0 keeps the plain over-blend.
