thorvg-test

This project is to test the performance impact of caching GlProgram on GlCanvas in real-time rendering scenarios, and also to test two newly added interfaces:

• tvg::Picture::load(uint32_t textureId, uint32_t width, uint32_t height)
• tvg::GlCanvas::target(int32_t fboId, uint32_t w, uint32_t h, int msaaSamples)

The test project is implemented based on imgui/glfw with an OpenGL backend and built using cmake. (thorvg is built using meson, but I am not very familiar with meson.) Therefore, thorvg is compiled first before building the project. So, if any modifications are made to the thorvg submodule, please delete the thorvg/build/install directory first and then recompile the project.

set(thorvgpath ${SAMPLE_LIBS_DIR}/thorvg/build/install/${ZPLATFORM}/${ZTARGET_ARCH})
if(NOT EXISTS ${thorvgpath}/lib/libthorvg-1.a)
    message(STATUS "Building thorvg...")
    execute_process(
            COMMAND ${SAMPLE_LIBS_DIR}/thorvg/build.sh local static release
            WORKING_DIRECTORY ${SAMPLE_LIBS_DIR}/thorvg
            OUTPUT_VARIABLE OUTPUT
            ERROR_VARIABLE ERROR
    )
endif ()

It is recommended to open and run this project using CLion, or you can directly run ./run.sh (only supports macOS).
