In the last two tutorials we looked at foliage textures and how to make the basic 3d objects for the foliage.
This one will give you the basic know-how to make a 3d tree so you foliage has somewhere to live:
You will need a 3d package of your choosing and be familiar with polygon editing.
A tree is made up from a trunk and branches. the branches are just simplified versions of the trunk, so we will look in depth into the trunk and skip the branches.
I am starting with a low poly object with 5 exterior points (4 always seems to low, 6 to perfect). This object has f divisions and is closed at the top:
you can see the object in blue above and the trunk we are aiming for in brown.
Looking at the face on, you can see I have started to select and move each segment of point to generally match the trunk. You can play around here with the heights, as there are no rules 🙂
Now we take the height segments and scale them getting narrower as we go towards the top:
starting with all sections (apart from the bottom) selected. You give each a twist:
You need to give your tree trunk a basic dirt brown colour (other colour are available):
Then, starting from the top, darken each section.
Now to make the trunk less ordered and more like a tree, we add a twist to each section:
And finally, move the vertexes about a bit:
We are not going to cover the beaches as they are really just a repeat of the steps above.
The only difference is instead of being 5 sections high, they are each 2 section hight with a cap.
One branches is created, then duplicated to make 3. Each modified to make it look different.
The branches are then positioned on the trunk in a pleasant way:
So now you have a tree trunk, some foliage and the foliage texture (I didn’t bother to texture my trunk!).
Simply putting them together should give you something like this:
