Toy story character rendering

Compiling

    cd <project_dir>
	mkdir build
	cd build
	cmake ..
	make

• if build succeeds, an executable toys will be created in build/
• keyframes.txt contains saved keyframes
• [extra] bezier.txt contains 4 control points of the bezier curve
  • camera moves along this bezier curve, once all the keyframes are completed.
• to capture frames in play mode, make capture_frame = true in View::View() in view.cpp.
  • these frames would be saved in build/frames as frame_<id>.ppm
• convert.sh is a script to process the saved frames and combine them to create a video.

Keyframe format

• each line in keyframes.txt corresponds to one keyframe
• <length (in number of frames)> <camera (rotation and position)> <rotation and position(if translatable) for all other nodes>
