Struct DecalRecord 

pub struct DecalRecord {
    pub model: [[f32; 4]; 4],
    pub inv_model: [[f32; 4]; 4],
    pub texture_slot: usize,
    pub tint: [f32; 4],
}

Per-decal data the renderer consumes each frame. Built once at GraphicsSystem init from the world’s Decal components.

model is the local→world transform of a unit cube spanning [-0.5, 0.5]^3 in local space. inv_model is its inverse; the fragment shader uses it to pull a reconstructed world-space sample point back into decal-local space and test it against the unit box. texture_slot indexes the renderer’s albedo texture pool; tint is RGB×alpha applied to every projected sample.

Fields

model: [[f32; 4]; 4]

Model matrix, column-major.

inv_model: [[f32; 4]; 4]

Inverse model matrix, column-major.

texture_slot: usize

Index into the shared texture pool for the decal’s image.

tint: [f32; 4]

Linear RGBA tint multiplied into the sampled image.

Implementations

impl DecalRecord

pub fn aabb(&self) -> ([f32; 3], [f32; 3])

World-space AABB enclosing the decal’s unit-cube volume. Used by the per-frame frustum-cull skip so a record that lands fully outside the camera frustum costs no draw call. The AABB is the transform of [-0.5, 0.5]^3 by model; for a non-rotated decal this exactly matches the authored size, and for a rotated decal it is the minimum AABB enclosing the rotated box.
