Expand description

Geometry source for rendering

Provides access to processed geometry data ready for GPU rendering. Implementations handle geometry processing, caching, and color assignment.

§Example

use bimifc_model::{GeometrySource, EntityId};

fn render_model(geometry: &dyn GeometrySource) {
    // Get all entities with geometry
    let entities = geometry.entities_with_geometry();
    println!("Rendering {} entities", entities.len());

    // Process each entity
    for id in entities {
        if let Some(geom) = geometry.get_geometry(id) {
            println!("Entity {:?}: {} triangles", id, geom.triangle_count());
            // Submit to GPU...
        }
    }

    // Or batch process for efficiency
    let all_geom = geometry.batch_geometry(&entities);
    for (id, geom) in all_geom {
        // Submit to GPU...
    }
}
