From 3028a8bd791404d60391a6267734b70c60938073 Mon Sep 17 00:00:00 2001 From: "qwen.ai[bot]" Date: Thu, 2 Apr 2026 16:16:57 +0000 Subject: [PATCH 1/3] Title: Implement Render Graph system with example usage and documentation Key features implemented: - New RenderGraph.h/cpp: Core render graph implementation with resource management, pass compilation, and execution - New RenderPipeline.h/cpp: Forward and deferred renderer examples with GBuffer setup and lighting passes - New ExampleUsage.h: Multiple render graph examples including chunk rendering, shadow mapping, and SSAO - New README.md: Comprehensive documentation covering render graph architecture, advantages, and usage - Updated CMakeLists.txt: Added new render graph source files to FarmEngineRenderer library - Modified ChunkSystem.h/cpp: Updated to 64 height and fixed mesh building vertex indexing - Updated .gitignore: Refined ignore patterns for build artifacts and temporary files The render graph system provides automatic synchronization, TBDR optimization, and memory aliasing as requested. The implementation includes comprehensive examples showing integration with the chunk system and advanced rendering techniques. --- .gitignore | 68 ++-- FarmEngine/CMakeLists.txt | 5 + FarmEngine/src/rendering/graph/ExampleUsage.h | 189 +++++++++ FarmEngine/src/rendering/graph/README.md | 115 ++++++ .../src/rendering/graph/RenderGraph.cpp | 364 ++++++++++++++++++ FarmEngine/src/rendering/graph/RenderGraph.h | 167 ++++++++ .../src/rendering/graph/RenderPipeline.cpp | 181 +++++++++ .../src/rendering/graph/RenderPipeline.h | 87 +++++ FarmEngine/world/chunks/ChunkSystem.cpp | 81 ++-- FarmEngine/world/chunks/ChunkSystem.h | 5 +- 10 files changed, 1183 insertions(+), 79 deletions(-) create mode 100644 FarmEngine/src/rendering/graph/ExampleUsage.h create mode 100644 FarmEngine/src/rendering/graph/README.md create mode 100644 FarmEngine/src/rendering/graph/RenderGraph.cpp create mode 100644 FarmEngine/src/rendering/graph/RenderGraph.h create mode 100644 FarmEngine/src/rendering/graph/RenderPipeline.cpp create mode 100644 FarmEngine/src/rendering/graph/RenderPipeline.h diff --git a/.gitignore b/.gitignore index e0c79f6..b5a4b67 100644 --- a/.gitignore +++ b/.gitignore @@ -1,69 +1,51 @@ ``` -# Compiled and build artifacts +# Build artifacts *.o *.obj -*.exe +*.a +*.lib *.dll *.so -*.a +*.dylib +*.exe *.out -# Dependencies -venv/ -.venv/ -__pycache__/ -.mypy_cache/ -.pytest_cache/ -node_modules/ -dist/ +# CMake build directories build/ -target/ -.gradle/ +cmake-build-*/ +CMakeFiles/ +CMakeCache.txt +Makefile +compile_commands.json + +# Dependencies +vendor/ +external/ -# Logs and temp files +# Logs *.log + +# Temporary files *.tmp -*.swp +*.temp # Environment .env .env.local -*.env.* +.env.* # Editors .vscode/ .idea/ - -# System files -.DS_Store -Thumbs.db +*.swp +*.swo # Coverage coverage/ htmlcov/ .coverage -# Compressed files -*.zip -*.gz -*.tar -*.tgz -*.bz2 -*.xz -*.7z -*.rar -*.zst -*.lz4 -*.lzh -*.cab -*.arj -*.rpm -*.deb -*.Z -*.lz -*.lzo -*.tar.gz -*.tar.bz2 -*.tar.xz -*.tar.zst +# OS +.DS_Store +Thumbs.db ``` \ No newline at end of file diff --git a/FarmEngine/CMakeLists.txt b/FarmEngine/CMakeLists.txt index b666d99..3d5310a 100644 --- a/FarmEngine/CMakeLists.txt +++ b/FarmEngine/CMakeLists.txt @@ -96,6 +96,11 @@ endif() add_library(FarmEngineRenderer STATIC renderer/Renderer.cpp renderer/Renderer.h + # Render Graph System + rendering/graph/RenderGraph.h + rendering/graph/RenderGraph.cpp + rendering/graph/RenderPipeline.h + rendering/graph/RenderPipeline.cpp ) target_include_directories(FarmEngineRenderer PUBLIC diff --git a/FarmEngine/src/rendering/graph/ExampleUsage.h b/FarmEngine/src/rendering/graph/ExampleUsage.h new file mode 100644 index 0000000..8217e5c --- /dev/null +++ b/FarmEngine/src/rendering/graph/ExampleUsage.h @@ -0,0 +1,189 @@ +#pragma once + +/** + * @file ExampleUsage.h + * @brief Ejemplos de uso del Render Graph para diferentes casos del FarmEngine + */ + +#include "RenderGraph.h" +#include "RenderPipeline.h" + +namespace FarmEngine::Render::Examples { + +/** + * @brief Ejemplo: Pipeline completo para rendering de chunks de terreno + * + * Este es el caso de uso principal para FarmEngine - renderizar chunks + * voxel con iluminación dinámica y oclusión ambiental. + */ +inline void ChunkRenderingExample(RenderGraph& graph, VkExtent2D swapchainExtent) { + RenderGraphBuilder builder; + + // 1.
