Day 2 : Begin R&D on terrain

Research on creating terrain with height maps

It has been some time since i last touch houdini

And it was my first attempt on creating terrain in houdini

I came to know about using height maps from Mr Douglas

Thus i deem that it will be a good headstart to venture from there

I searched on the forum and found some way to do it

There's example file to download

and illustration to clearly depict how the VOPSOP network connection works

Eg. 1

Eg. 2

Next i also found a great tutorial by Khermah in youtube

The height map was being done in VOP network

The VOP's complexity and to understand how each node functions

 was a challenge for me

I sought help from bryan and jia bao

I was taught to promote parameter to increase productivity

And the real functions of the pattern nodes

Eg. voronoi noise and worley noise has more optimized functionality, such as creating 3D noise 

Also clamp node to decrease the height of the displacement of the crackle

Basically i spend most of the time today to experiment nodes and test results in the VOP network

So my progress for today,

Earth terrain

The Close up

VOP network
It comprises Veins, Anti-aliasing and crackle pattern
