• Due to the deprecation of OpenGL on macOS, the fragment shader of slicing method I wrote with OpenGL 4.3 seems not available on macOS with OpenGL 4.1.

Usage

First, you will need a Data/ folder includes Scalar/ and Vector/ which contains the volume data and vector feild data respectively.

Compiler

• g++
• clang++
• mingw (64-bits is recommended)

Linking setting

If you want to compile manually, you can consider using the linking flags below:

• windows-args -lglfw3 -lopengl32 -lgdi32
• linux-args -lglfw3 -pthread -lXrandr -lXxf86vm -lXi -lXinerama -lX11 -ldl -lXcursor
• macos-args -stdlib=libc++ -lglfw -framework Cocoa -framework OpenGL -framework IOKit -framework CoreVideo -framework Carbon

Makefile

Or just use GNU make to automatically compile the source codes.

make
make run
