- Introduced a new structure ImGui_ImplSDLSurface3_Quad to represent quads. - Added functions to detect quads and check for constant colors and linear UVs. - Enhanced rendering functions to utilize quad detection for faster rendering paths. - Updated the rendering logic in ImGui_ImplSDLSurface3_RenderDrawData to leverage the new quad rendering capabilities. - Optimized Makefiles and build scripts to include optimization flags for better performance.
How to Build
Windows with Visual Studio's IDE
Use the provided project file (example_sdl2_surface.vcxproj) or open imgui_examples.sln.
Windows with Visual Studio's CLI
Use build_win32.bat or directly:
set SDL2_DIR=path_to_your_sdl2_folder
cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL2_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl2.cpp ..\..\backends\imgui_impl_sdlsurface2.cpp ..\..\imgui*.cpp /FeDebug/example_sdl2_surface.exe /FoDebug/ /link /libpath:%SDL2_DIR%\lib\x86 SDL2.lib SDL2main.lib /subsystem:console
# ^^ include paths ^^ source files ^^ output exe ^^ output dir ^^ libraries
# or for 64-bit:
cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL2_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl2.cpp ..\..\backends\imgui_impl_sdlsurface2.cpp ..\..\imgui*.cpp /FeDebug/example_sdl2_surface.exe /FoDebug/ /link /libpath:%SDL2_DIR%\lib\x64 SDL2.lib SDL2main.lib /subsystem:console
Linux and similar Unixes
Use the provided Makefile or directly:
c++ `sdl2-config --cflags` -I .. -I ../.. -I ../../backends \
main.cpp ../../backends/imgui_impl_sdl2.cpp ../../backends/imgui_impl_sdlsurface2.cpp ../../imgui*.cpp \
`sdl2-config --libs`
macOS
Use the provided Makefile or directly:
brew install sdl2
c++ `sdl2-config --cflags` -I .. -I ../.. -I ../../backends \
main.cpp ../../backends/imgui_impl_sdl2.cpp ../../backends/imgui_impl_sdlsurface2.cpp ../../imgui*.cpp \
`sdl2-config --libs`
