void	Submit (const RenderCommand &command)

void	Draw (GraphicsAPI &graphicsAPI, const CameraData &cameraData, const std::vector< LightData > &lights)
	Draw all submitted commands, then clear the queue.

Detailed Description

Accumulates RenderCommands during Update and draws them in one pass.

The queue is stateless across frames — it is filled during Update and drained (and cleared) during Draw, forming a clean producer/consumer pattern.

Draw()

void mnd::RenderQueue::Draw	(	GraphicsAPI &	graphicsAPI,
		const CameraData &	cameraData,
		const std::vector< LightData > &	lights
	)

Draw all submitted commands, then clear the queue.

For each command:

1. Bind the material's shader program.
2. Upload view, projection, and model matrices as uniforms.
3. Upload camera position and all light data as uniforms.
4. Bind the material (textures + float params).
5. Bind the mesh VAO and issue the draw call.

Parameters

graphicsAPI	The GL wrapper that issues the actual gl* calls.
cameraData	View and projection matrices for this frame.
lights	World-space light positions and colours.
