Here is a short video showing how to create a canyon by applying successive displacement layers in Terragen.
We start with coarse displacements and gradually apply finer and finer displacements.
We finish with the application of color layers, also based on fractals.
The complete project with comments is available on my Canyon 9 product page
Here an illustration of making Terragen picture step by step.. from a simple heightfield to a complete procedural shaped terrain and texturing
This scene is available in my store ready to play with it and add new iterations !
Starting by create global procedural shapes
Adding details without denaturate the landscape
Adding colors by altitude and/or by slope
Adding some vegetation (here some XFROG plants used) and adjust colors to better match. Find an interesting point of view.
Some books where I wrote some chapters few years ago, to explain, step by step, the creation process of my pictures :
Paysages 3D with a picture done with Terragen 0.9
Illustrations 3D with a picture done with KPT Bryce
It’s funny to see that these old books are still on sale….. hurry up before they become collectors 😉
Here some Terragen tests renders using some commercial photogrammetry models from Quixel megascans
Some wonderful and useful Xfrog, Inc models for lot of scenes I like to use :
Tropical with 20 species native to the world’s tropic regions. Each species includes 3 variations in age, size and shape for a total of 60 highly detailed, fully textured 3D models.
Oceania 3 with 20 species from all over Australia and Oceania. 9 variations in age, size and shape
USA Southwest contains 3D plant models of 20 species of cacti and succulents native to the deserts of the American Southwest. 3 variations in age, size and shape
USA Conifers contains 3D tree models of 20 species native to North America. 3 variations in age, size and shape
Europe 3 a collection of very detailed 3D trees. 20 species from all over Europe at different ages and varied seasons. 9 variations.
Agriculture 20 with species. 9 variations in age and shape
