示例1: GetAxisBaseIndex
public int GetAxisBaseIndex(Face face)
{
Vector3 normal = face.GetNormal();
int bestIndex = 0;
float bestDot = 0.0f;
for (int i = 0; i < 6; i++)
{
float dot = 0.0f;
Vector3.Dot(ref normal, ref BaseAxes[i * 3], out dot);
if (dot > bestDot)
{ // no need to use -altaxis for qbsp
bestDot = dot;
bestIndex = i;
}
}
return bestIndex;
}示例2: GetTextureCoordinate
public override Vector2 GetTextureCoordinate(Face face, Vector3 point)
{
Vector2 ret = new Vector2();
// Calculate coordinate axes if we don't have them (Quake, HalfLife/Valve200 will include them)
if (!face.XTexVector.HasValue || !face.YTexVector.HasValue)
{
Vector3 normal = face.GetNormal();
int bestIndex = GetAxisBaseIndex(face);
Vector3 xAxis = BaseAxes[bestIndex * 3 + 1];
Vector3 yAxis = BaseAxes[bestIndex * 3 + 2];
int planeNormIndex = (bestIndex / 2) * 6;

float XScale = face.Scale.X == 0.0f ? 1.0f : face.Scale.X;
