Changing sky color about oceansimulation

[Postrediori]

Hi!
Colours are set up in files with fragment shaders (with the *.frag extension) in the src/Ocean/data/ directory:

• https://github.com/Postrediori/OceanSimulation/blob/master/src/Ocean/data/ocean110.frag
• https://github.com/Postrediori/OceanSimulation/blob/master/src/Ocean/data/ocean130.frag
• https://github.com/Postrediori/OceanSimulation/blob/master/src/Ocean/data/ocean330.frag

The values for fog, sky and water are set up here as RGBA values between 0.0 and 1.0:

const vec4 fog_color      = vec4(0.25, 0.75, 0.65, 1.0);
const vec4 emissive_color = vec4(1.0, 1.0, 1.0,  1.0);
const vec4 ambient_color  = vec4(0.0, 0.65, 0.75, 1.0);
const vec4 diffuse_color  = vec4(0.5, 0.65, 0.75, 1.0);
const vec4 specular_color = vec4(1.0, 0.25, 0.0, 1.0);

These are almost identical files for different OpenGL versions. If not sure what version to use, modify all three.

I'm sorry to bit a year late, but in case you find this useful, there are now color changing controls in branch adjust_colors:

Added color UI in #9
