Struct EarlyGpuPreprocessNode

pub struct EarlyGpuPreprocessNode { /* private fields */ }

The render node for the first mesh preprocessing pass.

This pass runs a compute shader to cull meshes outside the view frustum (if that wasn’t done by the CPU), cull meshes that weren’t visible last frame (if occlusion culling is on), transform them, and, if indirect drawing is on, populate indirect draw parameter metadata for the subsequent EarlyPrepassBuildIndirectParametersNode.

Trait Implementations

impl FromWorld for EarlyGpuPreprocessNode

fn from_world(world: &mut World) -> Self

Creates Self using data from the given World.

impl Node for EarlyGpuPreprocessNode

fn update(&mut self, world: &mut World)

Updates internal node state using the current render World prior to the run method.

fn run<'w>( &self, graph: &mut RenderGraphContext<'_>, render_context: &mut RenderContext<'w>, world: &'w World, ) -> Result<(), NodeRunError>

Runs the graph node logic, issues draw calls, updates the output slots and optionally queues up subgraphs for execution. The graph data, input and output values are passed via the RenderGraphContext.

fn input(&self) -> Vec<SlotInfo>

Specifies the required input slots for this node. They will then be available during the run method inside the RenderGraphContext.

fn output(&self) -> Vec<SlotInfo>

Specifies the produced output slots for this node. They can then be passed one inside RenderGraphContext during the run method.
