Today’s process of working on scene.ts has certainly been one of the most complex parts of my work, since this file involves practically every visual and interaction mechanism I have designed. The imports for degree poses, snapshots and hand tracking points have been implemented and the constants for melody and expression colors, Devanagari fonts, monospace labels and the whole hand skeleton map were defined. Also, the SceneLabel and SceneInput interfaces were implemented; these two mechanisms serve as a sort of backbone for all the information needed by the renderer, such as hands, poses, thresholds, reachable degrees, video size, etc. Then, the geometry helper methods such as roundRect() and ribbonGeometry() were implemented; these methods determine how the swara ribbon would be drawn and how every cell would scale based on window size. Lastly, the drawScene() method is now partially implemented; at the moment it takes care of projection from camera coordinates, drawing of the octaves ladder, ribbon itself, intensity meter and conditional drawings of both hands with landmarks, tone lean arcs, gamak waves and role tags.

However, since this file is extremely large and complex, it results in numerous TypeScript errors such as undefined functions, type mismatches, unresolved references, and half-written helper methods like drawPoseGlyph(), which are used before the rest of the code is written. Some errors stem from hand tracking processing, some come from the ribbon rendering code, and some are generated by the math code responsible for resizing the video stream. At this point, the code has reached that chaotic state when the structure starts taking form while the compiler throws numerous errors due to the incomplete file. However, despite the chaos, I have managed to make the ribbon rendering code work, the octave ladder operational, and the hand skeleton drawing code properly working, which means that the visual layer is already being created. I am still working on the code, and hopefully, when more code will be written, many of the above errors will disappear automatically.

But yeah overall I fixed them overtime so now I am gonna start the COMPONENTS section around 200+ lines will be written I hope unless an error occurs lets see!!!
