H

heightfield

heightmap

A heightmap or heightfield is a raster image used to store values, usually surface elevation data.

L

luminance

TG2 converts RGB colours to greyscale by taking the luminance of the colour. This is essentially the brightness of the colour.

R

raster image

In computer graphics, a raster image, or bitmap, is a dot matrix data structure representing a generally rectangular grid of pixels, or points of color, viewable via a monitor, paper, or other display medium.

A heightmap or heightfield is an array of height values, usually in a grid which describe the height at specific points in a defined area. Heightfields are used to represent real-world and virtual terrain in a specific, easily converted format. Most heightfields can be represented as simple image data in grayscale, with black being minimum height and white being maximum height.

In computer graphics, a raster image, or bitmap, is a dot matrix data structure representing a generally rectangular grid of pixels, or points of color, viewable via a monitor, paper, or other display medium. Bit-mapped image formats in Terragen include raster heightfield terrains, image-based textures and masks, object textures, and rendered images saved to disk.
