From 4bf4a13dae515388b49f8d5f387a87f149eec4f7 Mon Sep 17 00:00:00 2001 From: scawful Date: Mon, 29 Sep 2025 09:04:10 -0400 Subject: [PATCH] Enhance graphics editor performance with batch processing and profiling - Integrated performance profiling using ScopedTimer in GraphicsEditor and ScreenEditor for better timing insights. - Implemented batch texture updates in GraphicsEditor and ScreenEditor to reduce individual texture update calls, improving rendering efficiency. - Enhanced tile rendering in ScreenEditor with pre-allocated vectors for batch operations, optimizing drawing performance. - Added safety checks and validation in various components to prevent crashes and ensure data integrity during rendering operations. - Updated Bitmap and Arena classes to support improved texture management and synchronization, enhancing overall graphics performance. --- src/app/editor/graphics/graphics_editor.cc | 9 +- src/app/editor/graphics/screen_editor.cc | 70 +++++-- src/app/editor/overworld/map_properties.cc | 4 + src/app/editor/overworld/overworld_editor.cc | 126 +++++++++--- src/app/editor/overworld/tile16_editor.cc | 58 +++--- src/app/gfx/arena.cc | 107 +++++++++-- src/app/gfx/bitmap.cc | 190 +++++++++++++------ src/app/gfx/bitmap.h | 9 +- src/app/gfx/tilemap.cc | 129 +++++++++---- src/app/gui/canvas.cc | 87 +++++---- src/app/zelda3/dungeon/room.cc | 26 +-- src/app/zelda3/overworld/overworld.cc | 14 +- 12 files changed, 600 insertions(+), 229 deletions(-) diff --git a/src/app/editor/graphics/graphics_editor.cc b/src/app/editor/graphics/graphics_editor.cc index 199836ae..1d4dc8cb 100644 --- a/src/app/editor/graphics/graphics_editor.cc +++ b/src/app/editor/graphics/graphics_editor.cc @@ -20,6 +20,7 @@ #include "app/gui/modules/asset_browser.h" #include "app/gui/style.h" #include "app/rom.h" +#include "gfx/performance_profiler.h" #include "imgui/imgui.h" #include "imgui/misc/cpp/imgui_stdlib.h" #include "imgui_memory_editor.h" @@ -272,6 +273,8 @@ absl::Status GraphicsEditor::UpdateGfxSheetList() { } absl::Status GraphicsEditor::UpdateGfxTabView() { + gfx::ScopedTimer timer("graphics_editor_update_gfx_tab_view");
