Computing Spatial Images

DeepDrill supports the creation of spatial images. To create such an image, set the enable key in the lighting section to yes:

./deepdrill top.ini -o top.map -o top.jpg lighting.enable=yes

When spatial image creation is turned on, DeepDrill mixes the derived pixel color values with the depth information from a normal map. The result looks like this:

Lighting can be controlled by two additonal keys, namely lighting.alpha and lighting.beta. The alpha parameter specifies the direction of the incoming light on the xy plane. The beta parameter describes the inclination of the light source. Decreasing this angle increases the 3D effect and vice versa:

./deepdrill top.map -o top.jpg lighting.enable=yes lighting.beta=10

./deepdrill top.map -o top.jpg lighting.enable=yes lighting.beta=60

In addition, DeepDrill offers a special GPU shader called relief.ini. This filter ignores the color information and converts the normal map directly into a grayscale image:

./deepdrill top.map -o top.jpg lighting.enable=yes gpu.illuminator=relief.glsl
