Fields

pipeline: RenderPipeline

Render pipeline for the volume pass.

bind_group_layout: BindGroupLayout

Bind group layout for recreation.

bind_group: BindGroup

Current bind group.

params_buffer: Buffer

Volume parameters buffer.

config: VolumeConfig

Configuration.

field_index: usize

Field index being rendered.

Implementations

impl VolumeRenderState

pub fn new( device: &Device, field_system: &FieldSystemGpu, config: &VolumeConfig, surface_format: TextureFormat, ) -> Self

Create a new volume render system.

pub fn update_bind_group( &mut self, device: &Device, field_system: &FieldSystemGpu, )

Update the bind group when field buffers change (after blur swap).

pub fn update_params_with_field( &self, queue: &Queue, inv_view_proj: Mat4, camera_pos: Vec3, field_extent: f32, field_resolution: u32, )

Update parameters with field info.

pub fn render<'a>(&'a self, render_pass: &mut RenderPass<'a>)

Render the volume into an existing render pass.

Call this before drawing particles for volume to appear behind them.
