Generate Rock Compound

I built an ICE compound generating a rock.
The algorithm is the same as the one that I posted before.
Please don't say to me that there are already compounds with similar.
I had decided to built this compound when I started my blog.

Compound Name: "sto Generate Rock" 

- Subdivisions: The number of segments.

- Rock Scale: Scale of the Rock.

- Cubelike(0-1): Shaped like a cube.

- Enable Cell Noise: Add the effect of cell noise.

- Displacement: How far points are moved.

- Number of Kernel Points: Sets the number of kernel points.

- Cell Noise Seed: The random seed of the cell noise.

- Variance: Specifies the range in which  kernel points will be moved.

- Smooth: How many times the smoothing algorithm is repeated iteratively.

- Enable Crack Noise: Add the effect of crack noise.

- Crack Depth: Depth of cracks.

- Crack Scale: Scale of cracks.

- Crack Noise Seed: The random seed of  the crack noise.

- Enable Rock Face Noise: Add the effect of rock face noise.

- Amplitude: How far points are moved.

- Scale: The granularity of the noise pattern.

- Medium Noise Seed: The random seed of the rock face noise (medium).

- Detail Noise Seed: The random seed of the rock face noise (detail).

Get an empty mesh(From the Get > Primitive > Polygon Mesh > empty).

Create an Ice tree in the empty mesh.

Add an "sto Generate Rock" compound and connect to the Ice tree.

Creating a cube by ICE Modeling

I built a ICE compound creating a cube because I could not find ports of subdivisions on "Primitive Mesh" node.

I thought that a cube can be create by combining 6 plane grids.
First Build arrays of vertex positions and polygonal descriptions for each plane.
Next combine each arrays.

Compound Name: "sto Create Cube"

 - Length: The size of the cube.

 - Subdivisions U: The number of segments(U-axis).

 - Subdivisions V: The number of segments(V-axis).

 - Subdivisions Base: The number of segments(Base-axis).

The following is the algorithm for creating grid topology.

Compound Name: "sto Create Grid"

 - U Length: The length of U-axis.

 - V Length: The length of V-axis.

 - Subdivisions U: The number of segments(U-axis).

 - Subdivisions V: The number of segments(V-axis).

Gaussian blur

I built a ICE compound to smooth/blur a weight map by a Gaussian function.

The following is the ICE tree of a Gaussian function and the graph of result.

The following is the function calculated by the ICE tree.

exp( -Distance * Distance / ( 2 * Radius * Radius ) )

---

Compound Name:  "sto Gaussian Blur Map"

- Mute: Disable the calculation.

- Radius: The value of blur size.

- Value: The Input value.

Improved stoCellNoiseMap

I Improved stoCellNoiseMap compound.

I added the check box that outputs square distance.
If you apply push deformer using weight map created by stoCellNoiseMap compound,This function is useful.
You can get different results.

 - Time varying:

       Move kernel points to different location 

　　　　every frame.
 - Noise Type: The noise function used to generate the turbulent values.
 - Time Frequency: Defines the speed at which the noise evolves over time.
 - Space Frequency: The granularity of the noise pattern.
