Separator Option

Separator TutorialTo Separate or not to Separate: This tutorial shows why and when to use the Separator option of Xfrog 3.5 – and when not.
Xfrog 3.5 is a procedural modeling application, specialized on organic branching structures.

Modeling Roots

Modeling RootsThis is the first tutorial of a small series, covering the creation of roots with Xfrog 3.5. It´s not a straight recipe to get finished roots for your tree. But it will show you the needed tools and approaches: Modeling with Tree Component Approach

This time we will make use of the Attractor component (FFD) to deform the base of the tree. Of course this is not a complete root system you will get as result, but in many cases it is enough to indicate some roots – and this is something you can doo with attractors: Modeling with Tree Deformers Approach

Tips & Tricks

Two video tutorials containing tips and tricks for Xfrog 3.5 users.

Part 1 | Part 2


Xfrog 3.5 Flower to Terragen


This tutorial shows how to create a flower in Xfrog 3.5 and how to bring it into Terragen 2.

Simple Daisy flower

This workshop will take you through the complete process of modeling a daisy flower. It´s an ideal start for Xfrog beginners. You will learn to build a good looking flower which only has a few polygons – ideal if you want to cover complete landscapes. You will also get some useful information about the user interface of Xfrog.

Detailed Daisy flower

This workshop will take you through the process of modeling a daisy flower. Despite the detail, the final flower only has about 1000 triangles. In the last step equations are used to create variations.
This tutorial is based on the Simple Daisy tutorial.

Daisy textures

If you want to build your own Xfrog models, then you normaly will also need some textures and materials for those objects.
This tutorial shows some simple techniques inside Photoshop, how to prepare scans or photographs and create textures from them. It should be no problem to tranfer those techniques to other applications like GIMP or Paintshop.

Goldenrod

This videotutorial will take you through the process of modeling a goldenrod plant. You will learn, how to distribute different kind of leaves along the stalk. This will enable you to put wilted leaves in the lower parts of the goldenrod and fresh leaves in the upper areas.

The Tree Project

This is a very detailed tutorial project, consisting of four video tutorials. During the first part you will build the base of the tree with some rotten branches. The second part covers the upper area. You will add branches to the tree, similar to the goldenrod, the trunk is made out of two tree components. During the third video you will learn to add leaves to the tree and also how to apply textures. The last part of this workshop shows how to add some grass to the base of the tree.

Xfrog 3.5 comes together with example plants. If you are in need of some textures for your tree, you could use those. I also encourage you to take a look at the Daisy textures tutorial, where you learn to create your own textures.


Pincushion cactus

Pincushion CactusMany people have asked for cacti tutorials. Especially because there´s a cacti library available (USA Southwest), many users of course want to build their own plants. I personally have some sort of love-hate relationship with this library. On the one side it was painfull to create, on the other side I learned so much about Xfrog during production of this library. Before I recorded this three-step video tutorial, I made some tests to make an approach as simple as possible – and also with least amount of tweaking handwork.

This time we will try to create something similar to a pincushion or barrel cactus. There are two main problems: how to create the ribs and how to distribute the needles. Especially because the appearance of the needles should be limited to the ribs, this sounds complicated at first – but it isn´t.

To understand this tutorial, you should at least have some basic knowledge about Xfrog, Hyperpatch and Attractors.

Step 1:

First we will create the base shape of the cactus. A Revo componet will serve to create the geometry and the Displace parameter will be used to create the ribs.

Watch the Step 1

Step 2:

Now we will use a Phiball to create the distribution pattern for the needles.

Watch the Step 2

Step 3:

Finally we´ll create the needles with help of a Horn component and make use of Attractors and Hyperpatch to create some irregularities..

Functions Workshop

Many people are scared about the use of functions inside Xfrog. This workshop will show some examples, how easy it can be and how much time and work functions can save for you.

Random variations of leaves and petals with rnd

Even when working with photorealistic textures, computer generated plats often look artificial. One of the reasons: the same leaf (shape and texture) shows up an all parts of the plant.
With help of the random function you can reduce this problem.

Random variations with Random component

You will fail, if you start Xfrog and search for the Random component – there is none. But the workshop below will show you, how to create a custom Random component.
