Struct re_space_view_spatial::visualizers::utilities::proc_mesh_vis::ProcMeshDrawableBuilder

pub struct ProcMeshDrawableBuilder<'ctx, Fb> {
    pub data: &'ctx mut SpatialViewVisualizerData,
    pub fallback: &'ctx Fb,
    pub line_builder: LineDrawableBuilder<'ctx>,
    pub line_batch_debug_label: DebugLabel,

}

To be used within the scope of a single VisualizerSystem::execute() call when the visualizer wishes to draw batches of ProcMeshKey meshes.

Fields

data: &'ctx mut SpatialViewVisualizerData

Bounding box and label info here will be updated by the drawn batches.

fallback: &'ctx Fb

line_builder: LineDrawableBuilder<'ctx>

Accumulates lines to render. TODO(kpreid): Should be using instanced meshes kept in GPU buffers instead of this immediate-mode strategy that copies every vertex every frame.

line_batch_debug_label: DebugLabel

solid_instances: Vec<GpuMeshInstance>

Accumulates triangle mesh instances to render.

query: &'ctx ViewQuery<'ctx>

render_ctx: &'ctx RenderContext

Implementations

impl<'ctx, Fb> ProcMeshDrawableBuilder<'ctx, Fb>

where Fb: TypedComponentFallbackProvider<ShowLabels> + TypedComponentFallbackProvider<Color>,

pub fn new( data: &'ctx mut SpatialViewVisualizerData, render_ctx: &'ctx RenderContext, view_query: &'ctx ViewQuery<'ctx>, line_batch_debug_label: impl Into<DebugLabel>, fallback: &'ctx Fb ) -> Self

pub fn add_batch( &mut self, query_context: &QueryContext<'_>, ent_context: &SpatialSceneEntityContext<'_>, constant_instance_transform: Affine3A, batch: ProcMeshBatch<'_, impl Iterator<Item = ProcMeshKey>, impl Iterator<Item = FillMode>> ) -> Result<(), SpaceViewSystemExecutionError>

Add a batch of data to be drawn.

pub fn into_draw_data( self ) -> Result<Vec<QueueableDrawData>, SpaceViewSystemExecutionError>

Final operation. Produce the re_renderer::QueueableDrawData to actually be drawn.
