Troubleshooting

Commit 389eb16: The original shader could cause a compute shader compiling error which wasn't very easy to trace. It is better to set the initial value to a very large number instead to something that isn't supported by some systems. Trace of this compiling error was seen in issue #24

Commit a265caa: Originally, moving astronaut or camera around would cause shaking similar to floating-point precision issues shaking. This should hopefully fix that.
