- Add CreateSwapChain to renderer using IEngineFactoryVk::CreateSwapChainVk
- InitWindowSurface creates the swapchain for native window surfaces
- Present now presents the active swapchain; ReleaseEGLResources releases it
- InitPbufferSurface keeps offscreen target for pbuffer EGL surfaces
- Update handoff; 16 Diligent tests pass
- Explicit read/draw FBO color attachments resolve to Diligent textures/renderbuffers
- CopyTexture between them for same-size color blits
- Update handoff; 16 Diligent tests pass
- ClearBufferfi clears depth+stencil on the current draw framebuffer
- ClearBufferiv/uiv now support GL_STENCIL via ClearStencil
- Update handoff; 16 Diligent tests pass
- PSO RTV count/formats now derive from the bound draw FBO color attachments
- Include RT layout in the last-PSO cache key
- Add DrawsToMultipleColorAttachmentsFromMobileGLState; 15 Diligent tests pass
- SyncRenderbuffer now reuses the cached Diligent texture so Clear/Draw/ReadPixels target the same resource
- ReadPixels resolves renderbuffer color attachments from the read FBO
- Add DrawsToRenderbufferFramebufferFromMobileGLState; 14 Diligent tests pass
- Resolve named UBOs through SPIRV-Reflect type names when block names are empty
- Read the bound GL buffer range at the frontend uniform-block binding point and upload it as a Diligent uniform buffer
- Add DrawsNamedUniformBlockFromMobileGLState test; 12 Diligent tests pass
- Reuse the last state PSO when program/render-state/topology/VAO layout is unchanged
- Update handoff with completed texture/sampler, UBO, framebuffer, and multi-draw work
Add DrawsIndexedFromMobileGLState: creates a GL program, VBO, EBO and VAO
through the frontend, then draws via DrawFromState(GL_TRIANGLES, ...,
GL_UNSIGNED_INT, nullptr) and verifies the offscreen center is red.
All 5 Diligent local tests pass.
- Add CreateTestTexture(): creates an RGBA8 texture, SRV and default sampler,
and attaches the sampler to the SRV.
- State PSOs now bind a static pixel-shader variable 'g_Texture' to the test
texture and commit shader resources before drawing.
- Add DrawsTexturedFromMobileGLState test using a real GL program with
sampler2D and interleaved position+UV attributes.
- All 4 Diligent local tests pass on Turnip Adreno 750.
The renderer now creates a D32_FLOAT depth target and binds it as DSV for all
render passes, so depth-test state wired earlier can actually work. Add
ClearDepth for depth clears. All Diligent local tests still pass.
CreatePipelineFromState now applies GL_STENCIL_TEST state (front/back funcs,
ops, read/write masks) and GL color write mask. DrawFromState sets the stencil
reference before drawing. All Diligent local tests still pass.
DrawFromState now uses MG_State viewport (with full-target fallback when the
viewport is uninitialized) and applies the scissor test rect when enabled.
The state-driven test sets an explicit glViewport and passes again.
Add DrawsFromMobileGLState test that creates a GL 3.2 program, buffer and VAO
through the real frontend, then draws through DiligentRenderer::DrawFromState
and verifies the offscreen pixels.
Also release PSO/vertex buffer before recreation to avoid Diligent debug
assertions about overwriting references.
All 3 Diligent local tests pass on Turnip Adreno 750.
DiligentRenderer now has DrawFromState() that:
- reads the current MobileGL program SPIR-V and creates Diligent shaders
- reads the current VAO enabled attributes and packs bound buffer data into
an interleaved vertex buffer
- creates a PSO with the matching input layout and primitive topology
- supports DrawArrays, DrawElements, triangle-fan and line-loop expansion
This is the first real front-end state wiring; it compiles and is used by
GLFunctionsTable DrawArrays/DrawElements, but is not yet covered by a
runtime state-driven test.
DiligentRenderer can now upload arbitrary vec2 vertex data into a dynamic
vertex buffer and draw it with the existing triangle PSO. The local sanity
test uses this path instead of the hardcoded triangle, verifying buffer
basics on Turnip Adreno 750.
BackendObject_Diligent now exposes real function-table entries backed by the
DiligentRenderer: Clear reads the current GL clear color from MG_State, and
DrawArrays/DrawElements currently render the built-in triangle as a
placeholder until buffer/VAO/program state is connected. Present flushes the
immediate context.
Local Diligent tests still pass on Turnip Adreno 750.
- Add DiligentRenderer: creates an offscreen RGBA8 render target, compiles a
GLSL vertex/pixel shader through Diligent's glslang path, creates a triangle
vertex buffer and pipeline, and supports clear/draw/readback.
- BackendObject_Diligent now owns a DiligentRenderer after device creation.
- Extend local sanity test to clear green, draw a red triangle, and verify
center is red and corner stays green.
- All Diligent local tests pass on Turnip Adreno 750.
- Add MOBILEGL_ENABLE_DILIGENT option; build DiligentCore Vulkan-only after
MobileGL's existing 3rdparty targets so shared glslang/SPIRV-Cross/xxHash
targets are reused instead of duplicated.
- Add BackendType::DiligentVulkan, config parsing, and backend-object switch.
- Add DiligentBackend::BackendObject_Diligent skeleton: creates a Diligent
Vulkan device/context when an adapter is available, advertises GL 3.2 core,
and returns an empty GL function table for now.
- Add local DiligentVulkanSanityTest that compiles/runs on the host (skips
device creation gracefully when no Vulkan adapter is present).
- Fix GLXImpl EGLDisplay member shadowing the X11 Display typedef, exposed by
GCC 16 + Diligent header include order.
