/* primdrawG.c, by Schnappy, 12-2020
- Draw a gouraud shaded mesh exported as a TMESH by the blender <= 2.79b plugin io_export_psx_tmesh.py
based on primdraw.c by Lameguy64 (http://www.psxdev.net/forum/viewtopic.php?f=64&t=537)
2014 Meido-Tek Productions.
Demonstrates:
- Using a primitive OT to draw triangles without libgs.
- Using the GTE to rotate, translate, and project 3D primitives.
Controls:
Start - Toggle interactive/non-interactive mode.
Select - Reset object's position and angles.
L1/L2 - Move object closer/farther.
L2/R2 - Rotate object (XY).
Up/Down/Left/Right - Rotate object (XZ/YZ).
Triangle/Cross/Square/Circle - Move object up/down/left/right.

based on primdraw.c by Lameguy64 (http://www.psxdev.net/forum/viewtopic.php?f=64&t=537)
2014 Meido-Tek Productions.
Demonstrates:
- Using a primitive OT to draw triangles without libgs.
- Using the GTE to rotate, translate, and project 3D primitives.
Controls:
Start - Toggle interactive/non-interactive mode.
Select - Reset object's position and angles.
L1/L2 - Move object closer/farther.
L2/R2 - Rotate object (XY).
Up/Down/Left/Right - Rotate object (XZ/YZ).
Triangle/Cross/Square/Circle - Move object up/down/left/right.

// Load a VAG file to SPU sound buffer and play it back.
//
// WAV creation: use ffmpeg to create a 16-bit ADPCM mono WAV file - change -ar to reduce filesize (and quality)
// $ ffmpeg -i input.mp3 -acodec pcm_s16le -ac 1 -ar 44100 output.wav
//
// WAV to VAG convertion using WAV2VAG : https://github.com/ColdSauce/psxsdk/blob/master/tools/wav2vag.c
// change -freq according to the -ar setting above
// $ wav2vag input.wav output.vag -sraw16 -freq=44100 (-L)
//
// Alternatively, you can use PsyQ VAGEDIT.EXE to change the sampling frequency of an existing VAG file.
