Offset

This script-fu allows to shift tiles/bricks/blocks one row or column out of two. It will help to draw brick walls, etc...

You can find "00 - Offset by froGgy" in Filters>2D Isometric-Fu>

I know this is not isometry, but I want to gather together in the same directory all the little script-fu that can help draw walls, floors, roofs etc...before their transformation into isometry.

example:

Isometric Wall

This script-fu skews an image in order to help to draw walls for isometric projection. It can also scale image with few options (ratio, a second layer with interpolation and opacity)...

For further explanation, see also http://registry.gimp.org/node/25040

You can find "02 - Isometric Wall" in Filters>2D Isometric-Fu>

example:

Isometric Floor

This script-fu turns a "flat" image into isometric image. This helps to draw floors. It can also scale image with few options (ratio, a second layer with interpolation and opacity)...

You can find "02 - Isometric Floor" in Filters>2D Isometric-Fu>

example:

Why is there "a second layer with interpolation and opacity" for scaling?
There is always a first layer without interpolation to try to keep the grain texture. This is practical for stone for example. The opacity of this layer is always 100%.

Isometric Tile and Template

This script-fu creates an isometric tile in your patterns and a template from it.

You can find ""00 - Isometric Tile and Template"" in File>Create>Patterns or in Filters>2D Isometric-Fu>

example:

Maths and Islamic Art & Design

Islamic art history is rich with geometric patterns and color.
The art certainly have many applications, whether in religious projects and what the formal plan can be used.

script-fu 'parametric curves'

This script is used to draw user defined or library parametric curves.
A simple java like math language is used to define curves or families of curves in GIMP layers. These can be exported to animated GIF's, SVG path, or included in GIMP images.

Flames

A script to generate an animated fire, tileable horizontally. Requires the "Incandescent" gradient that comes with the GIMP

After

Has the following options:
Image X and Y size: controls the size of the resultant image
Vertical and Horizontal Scale: controls the scale of the flames.
Flame Height: controls the maximum height of the flames as a fraction of the image height.
Detail: controls the detail on the flames, but too much makes them look strange
Gradient: Choose a different gradient to use

Crosshair Guides

This script puts guides at 50% Vertical and 50% Horizontal, to create a crosshair at the exact center of image/layer.

1 Inch Guides

This script creates guides at 1 inch intervals. It is dependent on pixels per inch settings.

10% Grid Guides

This script sets guides at every 10% Vertical and Horizontal.
