+### Some implementation details
+
+I got inspired by fogleman's [Craft](https://github.com/fogleman/Craft), but my development process bent over visual features, not gameplay ones.
+
+#### Rendering
+
+A couple of rendering optimizations are implemented, such as rendering only exposed faces, using face culling not to draw back faces of triangles,
+and frustum culling, which is not drawing chunks that are not visible.
+
+Each chunk has 2 vertex buffers, one for water blocks, the other for everything else. Using separate buffer for water is nessessary to ensure the right 
+rendering order, so everything will be seen through transparent blocks.
+
+Water has actual transparency, but there's also alpha testing (binary transparency). In shader the alpha value of fragment is checked, and if it's less than 0.5, 
+the fragment is discarded. Alpha testing allows to draw transparent glass, flowers, grass and tree leaves without usual problems that come with transaprency.
+
+When block in some chunk is changed, the chunk buffers are being completely rebuilt.
+
+To implement post-processing visual effects, such as depth of field, motion blur, gamma correction and saturation tweak, 
+I had to use separate framebuffer. So, the game is being rendered on a texture, then it's being rendered on yet another texture
+and during that the depth of field is applied, and in the final shader pass all other effects are applied and this image is actually what the player (you)
+sees. I really like the result, DoF and motion blur look very good.
