zeTexCoord

Use .new("texcoord") to create the object. It is used to hold texture coordinates of vertices and can be shared by multiple shape objects.

:add(s, t)

Adds a texture coordinate to the object.

:add{s, t, ...}

Adds texture coordinates to the object through Lua table, which should contain s and t coordinates.

:add(array)

Transfers data in the array of double type to the texture coordinate object. The number of vectors of the array must larger than or equal to two. Texture coordinates of s and t should be in the first and the second vectors.

:clear()

Clears data in the object.

:get(index)

Returns the coordinate s and t at the index (the first index is 0).

:get(arr)

Transfers texture coordinate data to the array. The array must have two vectors and the same number of records as the texture coordinate object.

:size()

Returns the number of texture coordinates the object contains.
