############# Brep to XML convertor of OpenCascade's '.brp' files ##############

# To compile the program just go to the brep_conversion folder and type

make

#The binary is built in the ./bin folder.

# In order to test the brep reader call the program from the console

# in the current directory with:

brep_conversion/bin/brep_to_xml <filename.brp>

## OLD Python program

python brep_conversion/src/brep_reader.py

# When asked for a filepath "please insert file path and name:" type

'./test/test_part/PartShape1.brp'

# or

"./test/test_part/PartShape1.brp"

# the quotes (or double quotes) are mandatory!

####################### FreeCAD placement representation #######################

# It consists of two vectors:

1. A 3-dimensional vector pointing to the center of the object

which is an arbitrary point defined at construction-time

(e.g. for a default box of dimensions x, y and z without any rotation

which consists of all the points in [0,x]x[0,y]x[0,z] in R^3, the center

of the box is in 0,0,0)

2. A 4-dimensional unit vector (Quaternion) q = q3 + q0i + q1j + q2k

q = q3 + (q0,q1,q2) = cos(a/2) + u*sin(a/2)

where a = angle of rotation (positive = clockwise) in radians

and u = unit vector along the (oriented) axis of rotation
