Day 19 - Terrain & Volcano

Terrain

Today I tried to do the procedural modeling, terrain tutorial. This tutorial taught me more about the vopsop functions and adding controls for user to adjust the terrain more easier. I started off by creating my first vopsop and make out the shape of the terrain first. I used the default and available terrain map as my terrain. Then in this "vopsop_make_terrain", I added these nodes inside to create the displacement for the terrain first.

After that, I'll have to normalise the curvature of the terrain so I'll create another vopsop for that.

Next, to create the slope and peak, I'll create another vopsop network.

I'll need to have some grass on my terrain so I'll create a vopsop for that.

This is the final look of it.

Volcano

I went to Houdini website to find new tutorials to learn and I saw this volcano tutorial which looks quite interesting so I decided to give it a try. 
This is the link for the tutorial:

For this tutorial, I used this pyro fx > volcano.

Firstly, I'm supposed to create a sphere object out then assign the volcano to it. The volcano pyro fx tool did mentioned that the object that we want to make it into a volcano is preferred to be a huge object so I scaled my sphere slightly bigger. After that, I dived into the sphere geometry and did some adjustment to the density.

After that, I went to the autodopnetwork. This visualisation > temperature allows me to see the wireframe of the heat of the volcano.

I want to create the wind control for the volcano so I'll create another geo for that and created out these node.

I did further adjustment so that we can see that the heat on the top part has more density than the bottom.

This is the network for the volumevop.

Initially, I couldn't get the correct look for my volcano, it doesn't look like a volcano as it's lacking of some density volume. So, I went to download the scene file and take a look. I realised that at the AutoDopNetwork > Guides > Multi, my density scale and shadow scale needs to be adjust. So the final look will be like this:

I'll go and render the volcano out as a movie file and post here tomorrow.
