Data that is valid for a batch of line strips.

Fields

label: DebugLabel

world_from_obj: Affine3A

Transformation applies to line positions

TODO(andreas): We don’t apply scaling to the radius yet. Need to pass a scaling factor like this in let scale = Mat3::from(world_from_obj).determinant().abs().cbrt()

line_vertex_count: u32

Number of vertices covered by this batch.

The batch will start with the next vertex after the one the previous batch ended with. It is expected that this vertex is the first vertex of a new batch.

overall_outline_mask_ids: OutlineMaskPreference

Optional outline mask setting for the entire batch.

additional_outline_mask_ids_vertex_ranges: Vec<(Range<u32>, OutlineMaskPreference)>

Defines an outline mask for an individual vertex ranges (can span several line strips!)

Vertex ranges are not relative within the current batch, but relates to the draw data vertex buffer.

Having many of these individual outline masks can be slow as they require each their own uniform buffer & draw call. This feature is meant for a limited number of “extra selections” If an overall mask is defined as well, the per-vertex-range masks is overwriting the overall mask.

picking_object_id: PickingLayerObjectId

Picking object id that applies for the entire batch.

depth_offset: DepthOffset

Depth offset applied after projection.

triangle_cap_length_factor: f32

Length factor as multiple of a line’s radius applied to all triangle caps in this batch.

This controls how far the “pointy end” of the triangle/arrow-head extends. (defaults to 4.0)

triangle_cap_width_factor: f32

Width factor as multiple of a line’s radius applied to all triangle caps in this batch.

This controls how wide the triangle/arrow-head is orthogonal to the line’s direction. (defaults to 2.0)

Trait Implementations

impl Default for LineBatchInfo

fn default() -> Self
