webGpu Subsystem

Low-level GPU acceleration layer mapping WebGL and WebGPU contexts directly to the native NeolyxOS NXRender compositor.

Internal Modules

gpu_device.hpp

Physical device abstraction, queue management, and memory allocations.

webgl_context.hpp

Implementation of the HTMLCanvasElement WebGL 1.0/2.0 rendering contexts.

gpu_pipeline.hpp

Compute and render pipeline states, shader module binding, and execution commands.

gpu_texture.hpp

Texture sampling, image loading formats, and offscreen framebuffer backing stores.

gpu_buffer.hpp

VBOs, IBOs, Uniform structures, and staging buffer uploads mapping to GPU memory.

canvas_renderer.hpp

Specialized 2D canvas drawing paths utilizing hardware-accelerated vectors.
