This sample presents a simple project that generates an island. It is used to test the performance of Instant Terra with terrains of different sizes.
This project contains three identical graphs with different terrain resolutions:
- The first graph generates terrains of size 2048 x 2048 with a resolution of four meters.
- The second graph generates terrains of size 4096 x 4096 with a resolution of two meters.
- The third graph generates terrains of size 8192 x 8192 with a resolution of one meter.
This project generates two terrains from a Perlin noise and a
cone, and composes them together to create the island.
A specific color ramp is created.
The last operation uses a curve to slightly modify the relief,
especially on the coast.
Changing the Perlin noise parameters changes the relief of the island; changing the angle of the cone of the cone changes its size.
