Height Map

Ensure that the given image meets the criteria for a height map.

Parameter table

No parameter available.

Detailed description

This rule is designed to verify that an image is a grayscale image, which is the basic requirement for a height map.

A height map is a representation where different shades of gray correspond to different elevations in terrain.

In its current implementation, this rule inherits the behavior of the RuleGrayscale without adding any additional checks. This means that any grayscale image could technically be considered a height map because height maps do not have any color information; they represent elevation through varying shades of gray.

It's important to note that while any grayscale image can be a height map, not all grayscale images are used as such. This rule does not assess the suitability of the image for any specific application as a height map; it only checks the image's color properties.

For more advanced validation specifically tailored to terrain representation, see the RuleTerrainHeightMap which introduces additional criteria to ensure the image accurately represents terrain elevation changes.

Future enhancements to this rule may include checks for specific patterns or gradients that are characteristic of the terrain being represented, which would allow for a more accurate assessment of an image's suitability as a height map.

Creator tips

When creating a height map, focus on ensuring that your image is in grayscale to accurately represent elevation. Every pixel's shade of gray corresponds to a different height, with darker shades representing lower elevations and lighter shades indicating higher elevations. This simple approach allows for a wide range of applications, from terrain generation in 3D environments to depth maps in image processing. Remember, while any grayscale image can technically serve as a height map, the specific patterns and gradients you use will define the realism and utility of your terrain representation.
