Overview

The UV Helper class contains methods allowing you to determine the location (UV coordinates) of a texture on a face. This class is particularly useful in determining how textures that have been manipulated using the Texture Tweaker should appear when exported to another file type

Use the Face.get_UVHelper method to create a UVHelper for a given face. See the TextureWriter class as well.

Instance Method Details

#get_back_UVQ(point) ⇒ Object

The get_back_UVQ method is used to get the UV coordinates for the back of a face.

Examples:

uv_helper = face.get_UVHelper true, true, my_texture_writer
face.outer_loop.vertices.each do |vert|
  uvq = uv_help.get_back_UVQ(vert.position)
  puts "u=" + uvq.x.to_s + " v=" + uvq.y.to_s
end

Returns point - a Point3d containing the UV coordinates where the X value is the U value, the Y value is the V value and the Z value is a Q value (which is not used).

Parameters:

  • point

    A Point3d object containing one of the 3D vertexes of the face.

Returns:

  • point - a Point3d containing the UV coordinates where the X value is the U value, the Y value is the V value and the Z value is a Q value (which is not used).

#get_front_UVQ(point) ⇒ Object

The get_front_UVQ method is used to get the UV coordinates for a front of a face.

Examples:

uv_helper = face.get_UVHelper true, true, my_texture_writer
face.outer_loop.vertices.each do |vert|
  uvq = uv_helper.get_front_UVQ(vert.position)
  puts "u=" + uvq.x.to_s + " v=" + uvq.y.to_s
end

Returns point - a Point3d containing the UV coordinates where the X value is the U value, the Y value is the V value and the Z value is a Q value (which is not used).

Parameters:

  • point

    A Point3d object containing one of the 3D vertexes of the face.

Returns:

  • point - a Point3d containing the UV coordinates where the X value is the U value, the Y value is the V value and the Z value is a Q value (which is not used).
