GPURenderer class abstract
GPU rendering abstraction layer.
Provides an interface for future GPU-accelerated rendering via flutter_gpu / Impeller when it becomes stable. Currently serves as documentation of the target API.
When flutter_gpu matures, implement GPURenderer with:
- gpu.RenderTarget for off-screen rendering
- gpu.CommandBuffer for batched draw calls
- gpu.Shader for custom GLSL/Metal shaders
- gpu.HostBuffer for vertex/index data upload
This allows vrlizate to seamlessly upgrade from Canvas to GPU rendering without changing the scene graph API.
