Relief Object

Relief Object

The relief map interprets the different grayscales within the image as altitude values. If you choose a color image, the grayscale is formed from the average value of the red, green and blue components of the bitmap picture. The brighter the pixel, the higher the elevation; the darker the pixel, the deeper it lies within the scene. In other words, darkness defines valleys, brightness is for mountains.

Interactive editing

The relief initially has three handles:

• Drag handle (1) to change the width (X).
• Drag handle (2) to change the height (Y).
• Drag handle (3) to change the depth (Z).
The handles of the relief primitive.

If you enable Spherical, only two handles appear:

• Drag handle (4) to change the globe’s radius (half the width — the first Size value).
• Drag handle (5) to change the height of the elevation (height - the second Size value).
Alternative handles for the relief primitive.
