Struct BoxShadowVertex

#[repr(C)]
pub struct BoxShadowVertex {
    pub pos: [f32; 2],
    pub uv: [f32; 2],
    pub color: [f32; 4],
    pub paint_size_px: [f32; 2],
    pub shape_offset_px: [f32; 2],
    pub shape_size_px: [f32; 2],
    pub radius_px: f32,
    pub blur_px: f32,
}

Box-shadow SDF vertex (position, UV, color, paint rect, shadow shape, radius, blur).

Examples

use ailloli_ui_render_wgpu::vertices::BoxShadowVertex;
let vertex = BoxShadowVertex { pos: [0.0; 2], uv: [0.0; 2], color: [0.0; 4],
    paint_size_px: [10.0; 2], shape_offset_px: [1.0; 2], shape_size_px: [8.0; 2],
    radius_px: 2.0, blur_px: 4.0 };
assert_eq!(vertex.blur_px, 4.0);

Fields

pos: [f32; 2]

Position in normalized device coordinates.

uv: [f32; 2]

Unit-quad coordinate across the shadow paint bounds.

color: [f32; 4]

Linear premultiplied-style RGBA shadow color expected by the shader.

paint_size_px: [f32; 2]

Paint-quad size in physical pixels.

shape_offset_px: [f32; 2]

Shadow shape offset within the paint quad, in physical pixels.

shape_size_px: [f32; 2]

Unblurred shadow shape size in physical pixels.

radius_px: f32

Shape corner radius in physical pixels.

blur_px: f32

Blur radius in physical pixels.

Implementations

impl BoxShadowVertex

pub const ATTRS: [VertexAttribute; 8]

Shader attributes at locations 0 through 7.

Examples

use ailloli_ui_render_wgpu::vertices::BoxShadowVertex;

Examples

use ailloli_ui_render_wgpu::vertices::BoxShadowVertex;
assert_eq!(BoxShadowVertex::desc().array_stride as usize,
    std::mem::size_of::<BoxShadowVertex>());
