- Document that Vulkan now passes an end-to-end upload/blit/download test
on real hardware.
- List recently landed fixes: shared vertex/fragment UBO, descriptor set
layout, render pass dependencies, image layout transitions, framebuffer
and sampler caching, grayscale swizzle, texture-enable uniforms.
- Add remaining gaps: iterative/pin-pong multi-pass Blit, 1/3-channel
upload/download alignment, and full viewer/proxy/export smoke tests.
- dynamic plan: mark that RenderManager::backend() now syncs with
DynamicRenderer's actual loaded backend after internal fallback.
- manual test plan: add checks in 10.2/10.3 that RenderManager reports
the actual runtime backend (OpenGL after Vulkan fallback).
No code changes; ctest passes 4/4.
- Add PickRenderableFormat / IsColorAttachmentSupported so 3-channel
Vulkan formats fall back to 4-channel when unsupported.
- Make oakvulkan target and C ABI check conditional on Vulkan_FOUND;
skip liboakvulkan build/dependencies when Vulkan headers/libs are
absent.
- Update Preferences tooltip to reflect Vulkan is an experimental
prototype that may fall back to OpenGL.
- Revise dynamic backend plan doc: phase 3/4/5 described as prototype
frameworks with runtime validation pending, and list recent Vulkan
fixes (init idempotency, descriptor/sampler lifetime, dynamic
viewport/scissor, render pass clear, format probing).
Both OAK_ENABLE_DYNAMIC_RENDER_BACKEND=ON and OFF configurations
build and pass ctest (4/4).
- Extract libolive-rendercore static library to minimize backend link boundary.
- Add DynamicRenderer adapter with C ABI (oakgl/oakvulkan shared libs).
- Make OAK_ENABLE_DYNAMIC_RENDER_BACKEND default ON with OpenGL fallback.
- Implement VulkanRenderer prototype (textures, shaders, UBO blit, readback).
- Add backend-neutral viewer readback path (offscreen -> QImage -> QPainter).
- Refactor PluginRenderer to be renderer-agnostic; OFX plugins fall back to CPU
path on non-OpenGL backends while preserving OpenGL render path.
- Add Renderer::AttachOutputTexture/DetachOutputTexture and C ABI forwards.
- Update docs/zh/render-backend-dynamic-plan.md for Phase 3/4/5.
