This program is free software: released under Creative Commons Zero
+(CC0) license
+Test scene that is generated simultaneously using:
+
+
+
conventional polygons
+
+
for realtime navigation, and
+
+
voxels
+
+
for on-demand raytracing
+
+
+
+
+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.
+
If alive cell neighbors count is 2 or 3, then cell survives,
+otherwise it dies.
+
Dead cell becomes alive if neighbors count is exactly 3.
+
+
+
+
+
+
+
+
+
+
+
+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"
+

1 Description
-
-Goal of this project is to show off capabilities of Sixth 3D
-engine. Also to show examples of its usage.
+Initial test for creating user interfaces in 3D and:
+
+
window focus handling
+
picking objecs using mouse
+
redirecting keyboard input to focused window
+
-
-
+
+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.
-
-Sample scenes rendered at interactive framerates by Sixth 3D engine.
+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.
+
+
+
+
+
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.

+
+
+Simple test scene. Easy to implement and looks nice.
