##volume rendering using ray casting algorithm ##

• This project is a demo to implement the volume rendering using Raycasting algorithm with modern OpenGL API and the shading language glsl.
• Written in C++ but in C style, just to explain the notation of Raycasting algorithm.
• To compile it, you need MinGW and Gnu Make and g++, only support Windows platform currently, it would be trivial to port to Linux platform.
• Dependencies: OpenGL4.0 and newer versions, glew, freeglut and glm, already included in this repo. If there is something wrong, maybe you need to compile the libs yourself.
• It is a two pass solution of the Raycasting algorithm.
• 
• 
• Just make in the command line to compile it.
