}

The lighting pass reads from the G-Buffer and evaluates all lights to produce an HDR color result.

Fields

enabled: bool

Whether this pass is enabled.

shader_handle: u64

Shader program handle.

lights: Vec<LightType>

All lights in the scene.

max_lights_per_pixel: u32

Maximum number of lights to evaluate per pixel.

use_light_volumes: bool

Whether to use light volumes (render spheres/cones for point/spot lights).

time_us: u64

Time taken (microseconds).

lights_evaluated: u32

Number of lights evaluated this frame.

ambient_color: [f32; 3]

Ambient color (added to all pixels).

ambient_intensity: f32

Ambient intensity.

ssao_enabled: bool

Whether to apply SSAO (screen-space ambient occlusion).

ssao_radius: f32

SSAO radius.

ssao_bias: f32

SSAO bias.

ssao_kernel_size: u32

SSAO kernel size.

environment_map: u64

Environment map handle (for IBL).

ibl_enabled: bool

Whether image-based lighting is enabled.

ibl_intensity: f32

IBL intensity multiplier.

Implementations

impl LightingPass

pub fn new() -> Self
