NVEC

Applies to: GT5, GT6 · Extension: .vec · Endian: Big

NVEC is a font format converted from .ttf, friendly for the PS3 and rendered through SPUs. It uses UTF-16.

Note

NVEC files are also present in PS4 GTs, but they are not read nor can be used.

Glyph Data

It is bit-packed, here is a sample on how to read it (snippet from PDTools.Files)

 public static GlyphShapes Read(BinaryStream bs, int size)
{
    var data = new GlyphShapes();
    byte[] bytes = bs.ReadBytes(size);
    BitStream bitStream = new BitStream(BitStreamMode.Read, bytes);

    ulong xMinBits = bitStream.ReadBits(12);
    data.XMin = BitValueToFloat((long)xMinBits, 12);

    ulong yMinBits = bitStream.ReadBits(12);
    data.YMin = BitValueToFloat((long)yMinBits, 12);

    while (true)
    {
        int flags = (int)bitStream.ReadBits(6);
        if (flags == 0)
            break;

        if ((flags & 0x20) != 0)
        {
            int elemSize = (flags & 0x0F) + 2;
            if ((flags & 0x10) != 0)
            {
                bool isPoint = bitStream.ReadBoolBit();
                if (isPoint)
                {
                    GlyphPoint point = new GlyphPoint();

                    int x = (int)bitStream.ReadBits(elemSize);
                    point.X = BitValueToFloat(x, elemSize);

                    int y = (int)bitStream.ReadBits(elemSize);
                    point.Y = BitValueToFloat(y, elemSize);

                    data.Data.Add(point);
                }
                else
                {
                    GlyphLine line = new GlyphLine();

                    line.Axis = bitStream.ReadBoolBit() ? GlyphAxis.Y : GlyphAxis.X;
                    int dist = (int)bitStream.ReadBits(elemSize);
                    line.Distance = BitValueToFloat(dist, elemSize);

                    data.Data.Add(line);

                }
            }
            else
            {
                GlyphQuadraticBezierCurve curve = new GlyphQuadraticBezierCurve();
                int x1 = (int)bitStream.ReadBits(elemSize);
                curve.P1_DistX = BitValueToFloat(x1, elemSize);

                int y1 = (int)bitStream.ReadBits(elemSize);
                curve.P1_DistY = BitValueToFloat(y1, elemSize);

                int x2 = (int)bitStream.ReadBits(elemSize);
                curve.P2_DistX = BitValueToFloat(x2, elemSize);

                int y2 = (int)bitStream.ReadBits(elemSize);
                curve.P2_DistY = BitValueToFloat(y2, elemSize);

                data.Data.Add(curve);
            }
        }
        else if ((flags & 0x01) != 0)
        {
            GlyphStartPoint startPoint = new GlyphStartPoint();

            int elemSize = (int)bitStream.ReadBits(5);
            int x = (int)bitStream.ReadBits(elemSize);
            startPoint.X = BitValueToFloat(x, elemSize);

            int y = (int)bitStream.ReadBits(elemSize);
            startPoint.Y = BitValueToFloat(y, elemSize);

            if ((flags & 0x02) != 0)
                startPoint.Unk = bitStream.ReadBoolBit();

            if ((flags & 0x04) != 0)
                startPoint.Unk2 = bitStream.ReadBoolBit();

            data.Data.Add(startPoint);
