This is an addon for the Godot game engine that can be used to create texture procedurally.
|
|
|
|
Its user interface is based on Godot's GraphEditor: textures are described as interconnected texture generators and operators.
|
|
|
|
|
|
|
|
## Generators
|
|
|
|
### Image
|
|
|
|
This operator reads a bitmap from disk
|
|
|
|
### Pattern
|
|
|
|
This generator creates a greyscale image by mixing an horizontal and a vertical pattern.
|
|
Patterns can either be based on a sine, triangle or square waveform (i.e. the color as function of the x or y coordinate).
|
|
The frequency (number of waves per unit) be configure for both axes.
|
|
Mix functions can also be configured.
|
|
|
|
|
|
|
|
### Bricks
|
|
|
|
This generator creates bricks greyscale patterns.
|
|
|
|
The Bricks generator has 5 parameters:
|
|
* the number of brick rows
|
|
* the number of bricks per row
|
|
* the offset between even and odd rows
|
|
* the mortar space between bricks
|
|
* the bevel at the edge of the bricks
|
|
|
|
The bricks generator has 2 output:
|
|
* the first one will show mortal as black and bricks as white (bevel being shown as a gradient). It can be used as mask to mix brick and mortar, or to generate depth and normal textures
|
|
* the second one will just show a different color for each brick. It can be used to affect the brick's colors (and will be used in the future to offset textures).
|
|
|
|
|
|
|
|
### Perlin Noise
|
|
|
|
The Perlin Noise generator creates a greyscale pattern and has 4 parameters:
|
|
* the horizontal and vertical scale of the first iteration
|
|
* the number of iteration
|
|
* the persistence (the weight ratio between 2 iterations)
|
|
|
|
|
|
|
|
### Voronoi Noise
|
|
|
|
The Voronoi Noise generator creates greyscale patterns based on Voronoi diagrams and has 3 parameters:
|
|
* the horizontal and vertical scale (the number of feature points)
|
|
* the "intensity" of the noise (used to adjust the generated color)
|
|
|
|
The Voronoi generator has 3 outputs:
|
|
* The first output shows a greyscale image where intensity depends on the distance to the cell centers
|
|
* The second output shows a greyscale image where intensity depends on the distance to the cell edges
|
|
* The third output shows a different color for each cell.
