Detailed Description

Holds batch group settings: which mesh instances belong together, layer assignments, dynamic flag, and maximum AABB size for spatial splitting.

A batch group acts as a recipe — at prepare() time, BatchManager collects all MeshInstances tagged with a group's id, groups them by material, and merges each sub-group into a single draw call.

Member Data Documentation

dynamic

bool visutwin::canvas::BatchGroup::dynamic = false

When true, transforms may change per frame (uses SkinBatchInstance trick). Phase 1: always false — only static batching is supported.

layers

std::vector<int> visutwin::canvas::BatchGroup::layers

Layer IDs this batch group applies to.

maxAabbSize

float visutwin::canvas::BatchGroup::maxAabbSize = 0.0f

Maximum AABB dimension for spatial splitting. 0 = no limit.
