forge-ui-rendering

Batch immediate-mode UI rendering on the GPU into a single draw call by streaming per-frame vertex and index buffers, applying a font atlas, and executing alpha blending within a dedicated rendering context.

Batch UI rendering for real-time applications by streaming dynamic per-frame buffers to the GPU and consolidating all Forge UI elements, font atlas glyphs, and alpha blending into one efficient draw call.

Yes, dynamic per-frame vertex and index buffer streaming handles UI growth dynamically, allowing all expanding UI elements and font atlas glyphs to be processed in a single batched draw call.

A font atlas supplies pre-rendered glyphs to the GPU pipeline, enabling text and icons to be drawn alongside UI elements with alpha blending in one batched draw call, reducing CPU overhead.

Yes, the single draw call UI pipeline integrates with the SDL GPU API, providing a straightforward initialization flow to handle context setup, buffer streaming, and alpha blending for real-time applications.

Multiple draw calls occur when text and icons are not batched; consolidating them into a font atlas with dynamic per-frame buffer streaming enables a single batched draw call for the entire UI pipeline.
