示例1: SetPosV
void DecalMesh::SetPosV( const Vector3F& newPos, const Matrix4& _newRot )
{
float zRot = _newRot.CalcRotationAroundAxis(2);
zRot = NormalizeAngleDegrees( zRot );
Matrix4 newRot;
newRot.SetZRotation( zRot );
// We don't need to ask the container (the TerrainMesh) where we
// will be, since the decal is patched to the terrain.
if ( newPos.x != pos.x || newPos.y != pos.y || newRot != rotation || !InList() )
{
pos = newPos;
rotation = newRot;
Rectangle3F base;
base.Set( -size / 2.0f, -size / 2.0f, (TERRAIN_MIN+0.01f),
size / 2.0f, size / 2.0f, (TERRAIN_MAX-0.01f) );
if ( InList() )

CalcAABB( base );

// Compute the texture matrix for this decal.
Matrix4 center, inverse, scale;
