The remaining bytes are **GLSL 330 source text**. +3. `glCreateShader(stage == Vertex ? GL_VERTEX_SHADER : GL_FRAGMENT_SHADER)` +4. `glShaderSource(shader, 1, &source, &length)` +5. `glCompileShader(shader)` — check `GL_COMPILE_STATUS`, log errors via `glGetShaderInfoLog`. +6.

Query sampler/texture uniform locations and set them to appropriate texture units with `glUniform1i`. +5. Cache and call `glUseProgram(program)`. + +**`MGG_Shader_Destroy`** — `glDeleteShader(handle)`. Invalidate any program cache entries referencing this shader (delete linked programs with `glDeleteProgram`). + +### Step 7: Input Layout (VAO) + +- **`MGG_InputLayout_Create`** — store the `elements[]` and `strides[]` arrays (as the current code already does).

Vertex attribute state is reconfigured on this VAO when the input layout or vertex buffer changes. + +### Step 8: State Application + +Implement the three state-setting functions to issue real GL calls. Use dirty flags to defer application to draw time. + +**`MGG_GraphicsDevice_SetBlendState`:** +- Store state pointer + blend factor, mark `blendDirty`. +- At draw time: `glEnable(GL_BLEND)` or `glDisable(GL_BLEND)`. Per-target (4 targets via `glBlendFuncSeparatei` / `glBlendEquationSeparatei` if GL 4.0+), or single-target on WebGL. Set `glBlendColor(r,g,b,a)`. Apply color write mask via `glColorMaski`. + +**`MGG_GraphicsDevice_SetDepthStencilState`:** +- Store state pointer, mark `depthStencilDirty`. +- At draw time: `glEnable/glDisable(GL_DEPTH_TEST)`, `glDepthFunc`, `glDepthMask`.

Depth bias: `glEnable(GL_POLYGON_OFFSET_FILL)`, `glPolygonOffset(factor, units)`. MSAA: `glEnable/glDisable(GL_MULTISAMPLE)`. + +### Step 9: Resource Binding + +Implement the resource binding functions. These store references and mark dirty bits — actual GL binding is deferred to draw time. + +- **`MGG_GraphicsDevice_SetConstantBuffer`** — store `buffer` at `slot` for `stage`, mark `uniformDirty`. +- **`MGG_GraphicsDevice_SetTexture`** — store `texture` at `slot` for `stage`, mark `textureDirty`. +- **`MGG_GraphicsDevice_SetSamplerState`** — store `state` at `slot` for `stage`, mark `samplerDirty`. +- **`MGG_GraphicsDevice_SetIndexBuffer`** — store index buffer handle and element size. +- **`MGG_GraphicsDevice_SetVertexBuffer`** — store `buffer` at `slot` with `vertexOffset`, mark `inputLayoutDirty`. +- **`MGG_GraphicsDevice_SetShader`** — store `shader` at `stage`, mark `shaderDirty`. +- **`MGG_GraphicsDevice_SetInputLayout`** — store `layout`, mark `inputLayoutDirty`. + +### Step 10: Draw Calls + +Implement a shared `ApplyState` helper called before every draw, then the three draw functions: + +**`ApplyState(device, primitiveType)` helper:** +1. If `shaderDirty`: look up / create linked program, `glUseProgram`. +2. If `blendDirty`: apply blend state GL calls. +3. If `depthStencilDirty`: apply depth/stencil GL calls. +4. If `rasterizerDirty`: apply rasterizer GL calls. +5. If `uniformDirty`: for each active UBO slot, `glBindBufferBase(GL_UNIFORM_BUFFER, slot, buffer->handle)`. +6. If `textureDirty`: for each active texture slot, `glActiveTexture(GL_TEXTURE0 + slot)`, `glBindTexture(target, texture->handle)`. +7. If `samplerDirty`: for each active sampler slot, `glBindSampler(slot, sampler->sampler)`. +8. If `inputLayoutDirty`: reconfigure VAO vertex attributes — for each element, bind the associated VBO (`glBindBuffer(GL_ARRAY_BUFFER, vbo)`), then `glVertexAttribPointer`. +9. If index buffer is set: `glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, indexBuffer->handle)`. +10. Clear all dirty flags. + +**`MGG_GraphicsDevice_Draw`** — `ApplyState`, then `glDrawArrays(topology, vertexStart, vertexCount)`. + +**`MGG_GraphicsDevice_DrawIndexed`** — `ApplyState`, compute index count from `primitiveCount` + `primitiveType`, then `glDrawElements(topology, indexCount, indexType, offset)`. + +**`MGG_GraphicsDevice_DrawIndexedInstanced`** — `ApplyState`, then `glDrawElementsInstanced(topology, indexCount, indexType, offset, instanceCount)`. + +### Step 11: Render Targets (FBO) + +**`MGG_GraphicsDevice_SetRenderTargets`:** +- If `count == 0` (default framebuffer): `glBindFramebuffer(GL_FRAMEBUFFER, 0)`, set viewport to backbuffer size. +- Otherwise: create/cache an FBO. For each target, `glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0 + i, target, texture->handle, 0)`. If the first target has a depth renderbuffer, attach it. Call `glDrawBuffers` with the attachment list. Check `glCheckFramebufferStatus`. +- Use `arraySlices` parameter for layered rendering (`glFramebufferTextureLayer` for 3D/array textures, or `GL_TEXTURE_CUBE_MAP_POSITIVE_X + slice` for cube faces). + +**`MGG_GraphicsDevice_ResolveRenderTargets`** — `glBlitFramebuffer` from MSAA FBO to resolve FBO (if multisampling), or no-op for non-MSAA targets. + +**`MGG_GraphicsDevice_GetBackBufferData`** — bind default framebuffer, `glReadPixels(x, y, width, height, GL_RGBA, GL_UNSIGNED_BYTE, data)`. + +### Step 12: Occlusion Queries + +- **`MGG_OcclusionQuery_Create`** — `glGenQueries(1, &query)` +- **`MGG_OcclusionQuery_Destroy`** — `glDeleteQueries(1, &query)` +- **`MGG_OcclusionQuery_Begin`** — `glBeginQuery(GL_SAMPLES_PASSED, query)` (desktop) or `GL_ANY_SAMPLES_PASSED` (WebGL2) +- **`MGG_OcclusionQuery_End`** — `glEndQuery(GL_SAMPLES_PASSED)` +- **`MGG_OcclusionQuery_GetResult`** — `glGetQueryObjectuiv(query, GL_QUERY_RESULT_AVAILABLE, &available)`, if available: `glGetQueryObjectuiv(query, GL_QUERY_RESULT, &pixelCount)`, return 1; else return 0. + +### Step 13: Effect Bytecodes + +Uncomment the effect bytecode includes at the top of `native/monogame/opengl/MGG_OpenGL.cpp` and enable `mg_effect.h`. The `.ogl.mgfxo.h` files are generated by the build system (`build/BuildShaders/BuildShadersOGL4Task.cs`). Once uncommented, `MGG_EffectResource_GetBytecode` will work via the shared implementation in `native/monogame/include/mg_effect.h`. + +### Step 14: Device Lifecycle Cleanup + +Tighten up the existing implemented functions: +- **`MGG_GraphicsDevice_Create`** — create the default VAO, initialize dirty flags, set initial GL state (`glEnable(GL_DEPTH_TEST)`, `glEnable(GL_BLEND)`, etc.). +- **`MGG_GraphicsDevice_Destroy`** — delete the default VAO, destroy the program cache (delete all linked programs), clean up FBO cache. +- **`MGG_GraphicsDevice_ResizeSwapchain`** — avoid destroying and recreating the GL context (current code does this destructively). Instead, just update the viewport/scissor and any swapchain-related state. +- **`MGG_GraphicsDevice_GetTitleSafeArea`** — return the backbuffer dimensions (same as what the Vulkan backend does). + +## Verification + +1. Build the `desktopgl` project via premake5 to confirm compilation with no errors. +2. Run the MonoGame test suite (`Tests/MonoGame.Tests.DesktopGL4.csproj`) — at minimum, device creation + clear + present should work after Steps 1–2. +To run the tests we need to run whem from the terminal on macos. +`cd` to `Artifacts/Tests/DesktopGL4/Debug`. Then directly run the `MonoGame.Tests` executable for example + +```bash +./MonoGame.Tests --test="MonoGame.Tests.Graphics.GraphicsDeviceTest.Clear" +``` + +3. After Steps 3–10, verify with a simple `SpriteBatch` draw (requires SpriteEffect shader, a texture, and a draw call). +4. After all steps, run the full test suite and verify visual parity with the Vulkan backend. + +## Decisions + +- **GL loader**: Keep `GL_GLEXT_PROTOTYPES` + SDL2 — no new deps. Windows not targeted (uses DX12). +- **Single file**: All code stays in `native/monogame/opengl/MGG_OpenGL.cpp`, matching Vulkan's pattern. +- **Scope**: Both desktop GL 4.1+ and Emscripten/WebGL2 paths, using `#ifdef MG_EMSCRIPTEN` where APIs diverge (e.g., `glGetBufferSubData` → `glMapBufferRange`, `glPolygonMode` → no-op, `GL_SAMPLES_PASSED` → `GL_ANY_SAMPLES_PASSED`). +- **Shader format**: The OpenGL4 bytecode container is identical to Vulkan's header format (slot bitmasks + bindings) followed by GLSL 330 text. Parse the same header, compile GLSL instead of creating SPIR-V modules. +- **Program linking**: Cache linked programs by VS+FS pair ID (same pattern as Vulkan's `MGVK_Program`). +- **State management**: Deferred/dirty-tracked like Vulkan — store state at set time, apply at draw time. diff --git a/src/NuGetPackages/MonoGame.Runtime.Linux.Vulkan/MonoGame.Runtime.Linux.Vulkan.csproj b/src/NuGetPackages/MonoGame.Runtime.Linux.Vulkan/MonoGame.Runtime.Linux.Vulkan.csproj index 3f0890e1861..0c8df6f4ee1 100644 --- a/src/NuGetPackages/MonoGame.Runtime.Linux.Vulkan/MonoGame.Runtime.Linux.Vulkan.csproj +++ b/src/NuGetPackages/MonoGame.Runtime.Linux.Vulkan/MonoGame.Runtime.Linux.Vulkan.csproj @@ -1,11 +1,18 @@  - + + runtimes\linux-x64\native PreserveNewest + + + runtimes\linux-arm64\native + PreserveNewest + \ No newline at end of file diff --git a/src/NuGetPackages/MonoGame.Runtime.Windows.DX12/MonoGame.Runtime.Windows.DX12.csproj b/src/NuGetPackages/MonoGame.Runtime.Windows.DX12/MonoGame.Runtime.Windows.DX12.csproj index 62ff158b0e5..cebaf553293 100644 --- a/src/NuGetPackages/MonoGame.Runtime.Windows.DX12/MonoGame.Runtime.Windows.DX12.csproj +++ b/src/NuGetPackages/MonoGame.Runtime.Windows.DX12/MonoGame.Runtime.Windows.DX12.csproj @@ -1,11 +1,18 @@  - + + runtimes\win-x64\native PreserveNewest + + + runtimes\win-arm64\native + PreserveNewest + diff --git a/src/NuGetPackages/MonoGame.Runtime.Windows.Vulkan/MonoGame.Runtime.Windows.Vulkan.csproj b/src/NuGetPackages/MonoGame.Runtime.Windows.Vulkan/MonoGame.Runtime.Windows.Vulkan.csproj index d5f992ef657..df2249c1457 100644 --- a/src/NuGetPackages/MonoGame.Runtime.Windows.Vulkan/MonoGame.Runtime.Windows.Vulkan.csproj +++ b/src/NuGetPackages/MonoGame.Runtime.Windows.Vulkan/MonoGame.Runtime.Windows.Vulkan.csproj @@ -1,11 +1,18 @@  - + + runtimes\win-x64\native PreserveNewest + + + runtimes\win-arm64\native + PreserveNewest + \ No newline at end of file
