Reflection, Refraction using CubeMapping.

Reflection, Refraction is fairly easy in OpenGL using both Shader and normal OpenGL pipeline. Today I tried both the classical method of Reflection Mapping and also using shaders.

The main objective of today's work was to render shiny Metals and Glass. The shiny metal needed a simple reflection mapping. The result is shown in the figure below:

Then I tried simple refraction mapping as well. To render glass, I needed both reflection as well as refraction. So, I mixed both reflection and refraction for my object.

Here is the ouput:

Note: I have used static Mapping techine.

The source code for the shaders used in above program are uploaded on my github: GLSL Source Code

Hope it helps :)
