cesiumjs-primitives

What problem does it solve?

Rendering complex, performance-critical scenes in CesiumJS can be exhausting when using high-level Entity APIs; by leveraging Primitive, GeometryInstance, and Appearance, developers can batch draw calls and render custom shapes with fine-grained control.

Core Features & Use Cases

• Low-level rendering with Primitive, GeometryInstance, and Appearance to optimize performance for large datasets.
• Built-in geometry types and support for custom shapes, ground primitives, and classification primitives.
• Use cases include batching thousands of shapes, rendering terrain-draped geometry, and achieving deterministic draw calls for large scenes.

Quick Start

Instantiate a simple Primitive with a GeometryInstance in a Cesium scene and attach an appropriate Appearance to render a static shape.
