Fantasy mountains

Name: Lan Lou Pennkey: lanlou

Demo

Current features:

• fbm combine worley noise terrain (two octaves of woley in the outter layer and 6 octaves of perlin noise together with one layer of large scale worley as mask in the outermost layer.

  • different noise comparision:

  pure worley fbm	pure perlin fbm

  combine of two:

  

• biomes based on terrain altitude and a large scale fbm perlin noise

  • including grasslands forest and mud land , and also mapping of terrain color to it's altitude

• (extra) worley noise ocean (acheived by compositing multiple layers of worley noise in fbm style based on u_time, each of which possess different velocity and direction)

• remapping of terrain:

pow 0.2	pow 1.0	pow 3.0

• (extra) alpha blending based on depth of terrain for ocean

  • you can notice water transparency changes with it's elevation

• (extra) cloud using multiple octaves of worley noise, alpha blending based on thikness

• (extra) sun using raycasting in camera space......

• terrain color layers based on terrain hight as well as slope angle

• (extra) simple lambert shading for terrain

• (extra) specularity and fresnel effect for ocean surface

GUI controls:

I only wrote a few controls which doesn't cover all features I've implemented from top to bottom, they are:

• powval : the remapping degree of terrain based on pow function
• sundirx,y,z : three direction component for sun directions
• waterele : water elevation
• clouddens : coverage of clouds
• use W,A,S,D keys to move across the mountains and ocean
• use RMB to rotate camera, LMB to translate camera, MMB to zoom in and out..

inspiration :

• grass land, clouds and mountains from anime feature film/Howl's Moving Castle by Hayao Miyazaki
