示例1: TrimPatch
///trim the patch's width in-place
void AiCarStandard::TrimPatch(Bezier & patch, float trimleft_front, float trimright_front, float trimleft_back, float trimright_back)
{
Vec3 frontvector = (patch.GetPoint(0,3) - patch.GetPoint(0,0));
Vec3 backvector = (patch.GetPoint(3,3) - patch.GetPoint(3,0));
float frontwidth = frontvector.Magnitude();
float backwidth = backvector.Magnitude();
if (trimleft_front + trimright_front > frontwidth)
{
float scale = frontwidth/(trimleft_front + trimright_front);
trimleft_front *= scale;
trimright_front *= scale;
}
if (trimleft_back + trimright_back > backwidth)
{
float scale = backwidth/(trimleft_back + trimright_back);
trimleft_back *= scale;
trimright_back *= scale;
}
Vec3 newfl = patch.GetPoint(0,0);
Vec3 newfr = patch.GetPoint(0,3);
Vec3 newbl = patch.GetPoint(3,0);
Vec3 newbr = patch.GetPoint(3,3);
if (frontvector.Magnitude() > 0.001)
{
