+# OpenGL: Fractal Forest
+### written in C++ using the OpenGL libraries

+- To get the program to read a custom file the make sure that the file has one of 
+these formats:
+
+- Code does not work if the file has an extra empty line
+
+               Len:4
+               Deg: 22.5

+- The stochastic tree must have the stochastic string and nothing else on the first line
+
+- There is currently no limit to the number of rules one can add
+
+- For the non stochastic file the rule -> must be found to record the rule
+
+- The stochastic file needs to have the F(): and in parenthesis the percentage values , the value must be out of a toal of 1.00 (e.g. 0.25, 0.25, 0.25, 0.25)
+
+- To compile the code use the correct directory and have all files in the same directory as the .cpp file
+
+- g++ FractalForest.cpp -lGLU -lglut -lGL
+
+- After compilation type in the terminal "./a.out" without the quotation marks
+
+- To close the program press the escape key
+
+- The program does have a moving camera but it will move very slow if openGL is running at a low frame rate
