Helios Renderer API Reference

Welcome to the Helios Renderer API reference. This section provides detailed documentation for the renderer's core components, high-level settings, and the underlying Hardware Interface (RHI).

High-Level API

The high-level API is integrated into the Helios ECS and provides easy-to-use resources and components for scene rendering.

• RenderSettings: Global rendering parameters, post-processing, and quality settings.
• RenderContext: The main interface for high-level render commands.
• RenderPlugin: The ECS plugin that initializes the renderer.

Renderer Hardware Interface (RHI)

The RHI is a low-level abstraction over modern graphics APIs (primarily Vulkan). It provides direct control over GPU resources and command submission.

• rhi::Device: The primary factory for GPU resources.
• rhi::CommandBuffer: Recording and submitting GPU commands.
• rhi::Texture: GPU texture and image resources.
• rhi::Buffer: GPU memory buffers for vertex, index, and uniform data.
• RHI Types: Common structures and enumerations used across the RHI.

Key Features

• Modern Graphics: Built on Vulkan with support for dynamic rendering and bindless descriptors.
• Clustered Lighting: Efficiently handle hundreds of light sources.
• Post-Processing: Built-in HDR, tonemapping, and bloom.
• Extensible: Create custom render passes and pipeline states through the RHI.
