Struct DepthPrePass 

pub struct DepthPrePass {
    pub enabled: bool,
    pub shader_handle: u64,
    pub items: Vec<u64>,
    pub use_gbuffer_depth: bool,
    pub rendered_count: u32,
    pub time_us: u64,
    pub depth_func: DepthFunction,
    pub depth_write: bool,
    pub alpha_test_in_prepass: bool,
    pub alpha_threshold: f32,
}

Depth pre-pass that writes only depth, enabling early-Z rejection in the subsequent geometry pass.

Fields

enabled: bool

Whether the depth pre-pass is enabled.

shader_handle: u64

Shader program handle for the depth-only pass.

items: Vec<u64>

Items to render in this pass (opaque, front-to-back sorted).

use_gbuffer_depth: bool

Whether to use the depth from the G-Buffer or a separate depth buffer.

rendered_count: u32

Statistics: number of items rendered in the pre-pass.

time_us: u64

Time taken for the depth pre-pass (microseconds).

depth_func: DepthFunction

Depth function (Less, LessEqual, etc.).

depth_write: bool

Whether depth writing is enabled.

alpha_test_in_prepass: bool

Whether to do alpha test in the depth pre-pass (for cutout materials).

alpha_threshold: f32

Alpha test threshold.

Implementations

impl DepthPrePass

pub fn new() -> Self

pub fn execute(&mut self, queue: &RenderQueue, _gbuffer: &mut GBuffer)

Execute the depth pre-pass using items from the render queue.

pub fn vertex_shader() -> &'static str

Get GLSL source for the depth-only vertex shader.

pub fn fragment_shader_alpha_test() -> &'static str

Get GLSL source for the depth-only fragment shader (alpha test variant).

Trait Implementations
