// Export Obj vertex data and save them into 8bit unsigned RAW file
|
||||
// You can choose between two modes:
|
||||
// - interleaved (planar = false) - where vertices are saved one after another, xyzxyzxyzxyz....
|
||||
// - planar (planar = true) - where first X coordinates are dumped, then Y and finally Z, xxxxxx...yyyyyy...zzzzzz
|
||||
//
|
||||
// Since 8 bits per coordinate is used, coordinates are quantized and normalized to have values between -120 to 120
|
||||
|
||||
// Usage:
|
||||
// - setup filename of your OBJ file (without extension)
|
||||
// - run - OBJ file is loaded and rendered, corresponding RAW file is saved
|
||||
// - move mouse to rotate object
|
||||
//
|
||||
// Keys:
|
||||
// - o - reload original OBJ file and regenerate RAW
|
||||
// - r - load RAW file with name <filename>_res.raw
|
||||
// - SPACE - save image and resulted OBJ file
|
||||
//
|
||||
// Sonification process (filename: teapot):
|
||||
// - setup filename (teapot) and planar variable (true or false)
|

// - run, scripts loads teapot.obj and saves teapot/teapot.raw
