Description

Graphics rendering infrastructure.

This namespace provides the core rendering system including rendering devices, render commands, queues, passes, and vertex definitions. Encompasses asset, model, and shader management functionality for comprehensive 3D graphics rendering. Provides a platform-independent rendering abstraction that can be implemented by various graphics APIs (OpenGL, Vulkan, DirectX).

Enumerations

ClearFlags

enum class helios::rendering::ClearFlags

strong

Defines bitmask flags for clearing render buffers before drawing.

Enumeration values

None	No buffers are cleared (= 0)
Color	The color buffer is cleared (= 1 << 0)
Depth	The depth buffer is cleared (= 1 << 1)
Stencil	The stencil buffer is cleared (= 1 << 2)

These flags can be combined using bitwise OR operations to specify which buffers (color, depth, stencil) should be cleared before rendering.

Example usage: ```cpp // Clear both color and depth buffers int clearFlags = std::to_underlying(ClearFlags::Color) | std::to_underlying(ClearFlags::Depth); viewport.setClearFlags(clearFlags); ```
