Tri-planar shading must be implemented such that:

• A seperate texture is used for:
  • Top
  • The rest
• Texture blending is used between vertices.

Terrain digging must be implemented in such a way that:

• Terrain digging can be performed with two parameters:
  • The exact position to dig, in floating point precision.
  • The dig radius, in floating point precision.

A circle is then dug from the terrain (as close to as possible, given the block resolution), given point and radius.

The current terrain implementation uses MSTerrain in the Farseer library. However this has very poor performance and the implementation itself is quite buggy.

A new class will be implemented such that:

• It uses no geometric shapes.
• Each point in the terrain is represented by 2 possible states - 'ground' or 'air'.
• Rather than storing an entire bitmap pixel-by-pixel, the terrain will be represented by a quad-tree data structure. This way, large segments of 'pure-ground' can be represented by a single rectangle to reduce the memory impact.

Investiage:

• Investigate if this class can be hooked into the Box2d/Farseer system by wrapping the object with a Body. Collision-detection methods of the Body will be overridden to make checks on this terrain class.
