 ## 1. Functionality
+
 - Simple 3D engines with planty of models (may be generated programmatically or loaded from files) and scene objects (they have their own properties such as position and rotation).
 - Transform matrices with homogeneous coordinates: shifting, scaling, rotationg, perspective.
 - Pruning of invisible edges with Roberts algorithm.
@@ -13,6 +14,7 @@
 - Many helpful math (generating of transform matrices, matrices and vectors multiplication, dot production, normals, and reflected vectors calculations) and other functions.
 
 ## 2. Control
+
 - Left/right arrow — scene rotating.
 - Z/X keys — scene scaling.
 - Q/E keys — change light intensity.

 ## 4. Interesting points
+
 - During generation of dodecahedron initially pentagonal edges are created, which then are being splitted into 3 triangles.
 - Sphere model is creating through recursive "inflation" of tetrahedron. Recursion depth is under control: depth 0 gives 12 verticies and 20 edges (usual tetrahedron), depth 1 — 42 verticies and 80 edges, depth 2 — 222 verticies and 320 edges.
 - "Garlic" model was created from sphere transforming all the verticies this way: if Y greater than 0, than Y is increasing; if X or Z are close to 0, than other coordinate if decreasing. File `data.cpp`, function `createGarlic()`.

 - To reduce rendering time when using Z-buffer and light shading, picture dimensions are divided by 2.
 
 ## 5. Structure of model file
+
 The model files consist of 2 kinds of lines:
 - Vertex description: `0 x y z` where x,y and z are float numbers.
 - Triangle description: `1 a b c` where a, b and c are vertex indices.
 
 Lines of different kinds may be passed in any order, only relative order of vertices must be the same to keep their indices.
