- 2 cell states: alive / dead + +
- Each cell sees 8 neighboring cells. + +
- If alive cell neighbors count is 2 or 3, then cell survives, +otherwise it dies. + +

- TODO:

-
+
- Improve focus handling:
+
-
+
- Perhaps add shortcut to navigate world without exiting entire +stack of focus. + +
- Possibility to retain and reuse recently focused elements. + +
- Store user location in the world and view direction with the +focused window. So that when returning focus to far away object, +user is redirected also to proper location in the world. + +
+ - Possibility to store recently visited locations in the world and +return to them. + +
+ - Improve focus handling:

- TODO: instead of projecting 2D visualizations onto 3D space, +visualize some formula using all 3 dimensions avaliable. + +

2 Overview
++Goal of this project is to show off capabilities and API usage of +Sixth 3D engine. +
+ ++All example scenes in this repository render at interactive +framerates. +
+ ++Download runnable JAR file: sixth-3d-demos.jar +
+ ++To start demo application, use command: +
++java -jar sixth-3d-demos.jar + ++
3 Navigating in space
+| key | +result | +
|---|---|
| cursor keys | +move: left, right, forward, backward | +
| mouse scroll wheel | +move: up, down | +
| dragging with mouse | +look around | +
4 Example scenes in this repository
+4.1 Raytracing through voxels
+
+
+Test scene that is generated simultaneously using: +
-
-
+Instead of storing voxels in dumb [X * Y * Z] array, dynamically +partitioned octree is used to compress data. Press "r" key anywhere in +the scene to raytrace current view through compressed voxel +datastructure. +
+4.2 Conway's Game of Life
++The Game of Life, also known simply as Life, is a cellular automaton +devised by the British mathematician John Horton Conway in 1970. +
-
+
+Current application projects 2D game grid/matrix onto three +dimensional space. Extra dimension (height) is used to visualize +history (previous iterations) using glowing dots suspended in space. +
+ ++Usage: +
+| key | +result | +
|---|---|
| mouse click on the cell (cell) | +toggles cell state | +
| <space> | +next iteration | +
| ENTER | +next iteeration with the history | +
| "c" | +clear the matrix | +

1 Description
--Goal of this project is to show off capabilities of Sixth 3D engine. Also to -show examples of its usage. +Window focus acts like a stack. +
+ ++When window is clicked with the mouse, previously focused window (if +any) is pushed to the focus stack and new window receives focus. Red +frame appears around the window to indicate this.
++When ESC key is pressed, window focus is returned to previous window +(if any). +
-
+
+When any window is focused, all keyboard input is redirected to that +window, including cursor keys. To be able to navigate around the world +again, window must be unfocused first using ESC key.
