3D Terrain Generator

!!! Use TurboWarp as it is faster and higher resolution.

A 3D procedural terrain generator and hydraulic erosion simulator based on my image editor's code.
Create perlin noise terrain or import your own height map. Run erosion simulations on this terrain, add textures, and export in a variety of formats including 3D meshes as .obj!

INSTRUCTIONS:
Go through each of the 4 tabs in order. Each tab provides settings which you can edit by clicking on the text. A slider can be dragged or alternatively, type the desired value with your keyboard. To apply those changes, you have to click the relevant button, e.g. "run" or "generate".

You have access to multiple view modes at the top of the screen. Choose between greyscale height map, normal map, and texture / colour map. There are also 2D and 3D view buttons.

Additional settings can be accessed from the bottom-right button.

Most inputs have additional info text you can read.
The preceding tags are:
[FAC] - factor. A value used in multiplication.
[TU] - terrain units. A unit of measurement in this project. There are 255 units in an 8-bits-per-channel heightmap.
[PX] - pixels.
[NUM] - number, no special properties
[RGB] - an RGB colour, 8-bits-per-channel
[PERCENT] - a percentage value, ranging from 0-100.
[ANGLE] - an angle, ranging from 0-360.

TextImage is the recommended format.
