Process

I created pastel L-System trees for this project. I did so by creating a Turtle class and a set of rules to expand the tree grammar and to draw the actual tree. 

There are some parameters you can edit to change the tree shape. They are the following:

• Iterations: how many iterations should the grammar be parsed for the LSystem to grow

• Leaf_Density: how many leaves are in the tree

• Branch_Angle: adjust the angle of the branches

• Leaves_Color: change the color of the leaves

• Branch_Color: change the color of the branches

• Thick branch: use this check box to make the branches thick or not

• Leaf_Type: this is a drop down menu which lets you choose from three different models to use for the leaves! You can choose from regular leaves, roses, or even stars!

This L-System makes use of techniques such as instanced rendering to draw the branches and leaves, as the code keeps track of transformation matrices which are later applied in the instanced-mat-vert shader. The tree is drawn through using segments made out of a cylinder obj.
