Terrain transformation nodes

The Terrain transformation nodes modify the terrain.

• Change size: This node changes the size and resolution of a terrain.
• Upscaling: This node increases the resolution of a terrain.
• Smooth: This node smooths a terrain by replacing the height of a vertex by the average of the height of its neighbors.
• Soften: This node softens a terrain, which can correspond to accelerated aging.
• Flatten edges: This node flattens the four edges of a terrain so that they are at zero altitude.
• Sharpen: This node accentuates the details of a terrain.
• Scale & offset: This node sets the scale and offset of the terrain.
• Min & max heights: This node modifies the minimum and maximum heights of a terrain.
• Apply curve: This node modifies the terrain profile by changing the heights of all the vertices on a curve that define the terrain heights.
• Flip X: This node flips the terrain around the X axis.
• Flip Y: This node flips the terrain around the Y axis.
• Crop: This node retrieves an input terrain and Crops it in order to output only a part of the terrain.
• Terrace: This node modifies a terrain by creating terraces
• Swirl: This node creates a rotation distortion on the terrain.
• Gamma correction: This node modifies the colors of a terrain with a color map.
• Brightness & contrast: This node modifies the luminosity and constrast of a terrain with a color map.
• Warp: This node distorts a terrain.
• Stretching warp: This node applies variable deformations to warp a terrain.
• Directional warp: This node transforms a terrain using another terrain that determines the displacement at each value.
• 4-direction warp: This node deforms a terrain by applying a deformation in four different directions and by mixing the results obtained.
• Vector warp: This node distorts a terrain using two input terrains.
• Blur: This node applies a blur to a terrain.
• Blur effect: This node applies blur effects to  a terrain.
• Directional blur: This node applies a blur to a terrain in a given direction.
• Vector blur: This node applies a vector blur to a terrain.
• Transform terrain: This node modifies the first terrain before it is inserted into a second terrain.
