RenderBuffer3D (Mibo)

RenderBuffer3D Type

Namespace: Mibo.Elmish.Graphics3D
Assembly: Mibo.MonoGame.dll
Base Type: obj
All Interfaces: IDisposable

An allocation-friendly buffer for 3D render commands.

Commands are accumulated each frame via RenderBuffer3D.Add, then executed in insertion order by the active pipeline. The pipeline may re-sort internally if needed for state efficiency (e.g., front-to-back, material batching), but the buffer itself does not impose an order. Uses ArrayPool for the backing store to avoid per-frame heap allocations. The buffer is designed to be cleared and repopulated each frame. RenderBuffer3D.Clear resets the count without deallocating the internal array.

`this.AddSpotLight` Full Usage: `this.AddSpotLight` Parameters: light : `SpotLight3D` Modifiers: inline	light : `SpotLight3D`
`this.Clear` Full Usage: `this.Clear`	Clears all commands from the buffer without deallocating the backing array. Call this at the start of each frame before populating with new commands. Resets the count every frame (clearing thousands of struct-DU slots per frame is a hot-path cost we avoid), but periodically zeroes the backing array (~every 300 frames) so stale managed refs (Model/Texture2D/Effect) in slots above count can't keep unloaded assets alive indefinitely after a scene shrinks. Dispose also clears. This matches `RenderBuffer2D.Clear` and the raylib buffers.
`this.Count` Full Usage: `this.Count` Returns: `int`	The number of commands currently in the buffer. Returns: `int`
`this.DepthPostProcessCount` Full Usage: `this.DepthPostProcessCount` Returns: `int`	Number of `PostProcessWithDepth` commands added since the last `Clear`. When > 0, the pipeline produces a camera-POV depth target this frame so depth-needing effects (fog, depth-of-field, SSAO) can sample `PostProcessContext3D.Depth`. Zero on frames with only color-only `PostProcess` actions, so the depth pass is skipped entirely. Returns: `int`
`this[i]` Full Usage: `this[i]` Parameters: i : `int` Returns: `Command3D`	Gets the command at the specified index. i : `int` Returns: `Command3D`
`this.PostProcessCount` Full Usage: `this.PostProcessCount` Returns: `int`	Number of `PostProcess`/`PostProcessWithDepth` commands added since the last `Clear`. Lets a pipeline skip the post-process drain (and its per-frame allocation) when the view emits none. Returns: `int`
`this.Sort` Full Usage: `this.Sort` Parameters: comparer : `IComparer<Command3D>`	Sorts commands using the provided comparer. Pipelines may call this internally to optimize draw order. comparer : `IComparer<Command3D>`
