Detailed Description
Indicates a coordinate-system transform on vertices.
TransformStates are the primary means for storing transformations on the scene graph.
Transforms may be specified in one of two ways: componentwise, with a pos- hpr-scale, or with an arbitrary transform matrix. If you specify a transform componentwise, it will remember its original components.
TransformState objects are managed very much like RenderState objects. They are immutable and reference-counted automatically.
You should not attempt to create or modify a TransformState object directly. Instead, call one of the make() functions to create one for you. And instead of modifying a TransformState object, create a new one.

Constructor & Destructor Documentation
◆ ~TransformState()
|
virtual |
The destructor is responsible for removing the TransformState from the global set if it is there.
Definition at line 78 of file transformState.cxx.
Member Function Documentation
◆ compare_to() [1/2]
|
inline |
Provides an arbitrary ordering among all unique TransformStates, so we can store the essentially different ones in a big set and throw away the rest.
Note that if this returns 0, it doesn't necessarily imply that operator == returns true; it uses a very slightly different comparison threshold.
Definition at line 30 of file transformState.I.
◆ compare_to() [2/2]
| int TransformState::compare_to | ( | const TransformState & | other, |
| bool | uniquify_matrix | ||
| ) | const |
Provides an arbitrary ordering among all unique TransformStates, so we can store the essentially different ones in a big set and throw away the rest.
Note that if this returns 0, it doesn't necessarily imply that operator == returns true; it uses a very slightly different comparison threshold.
If uniquify_matrix is true, then matrix-defined TransformStates are also uniqified. If uniquify_matrix is false, then only component-defined TransformStates are uniquified, which is less expensive.
Definition at line 117 of file transformState.cxx.
References get_mat.
◆ components_given()
|
inline |
Returns true if the transform was specified componentwise, or false if it was specified with a general 4x4 matrix.
If this is true, the components returned by get_pos() and get_scale() will be exactly those that were set; otherwise, these functions will return computed values. If this is true, the rotation may have been set either with a hpr trio or with a quaternion; hpr_given() or quat_given() can resolve the difference.
Definition at line 260 of file transformState.I.
◆ get_hash()
|
inline |
Returns a suitable hash value for phash_map.
Definition at line 38 of file transformState.I.
◆ get_mat3()
|
inline |
Returns the 3x3 matrix that describes the 2-d transform.
It is an error to call this if is_2d() returned false.
Definition at line 526 of file transformState.I.
◆ get_pos2d()
|
inline |
Returns the pos component of the 2-d transform.
It is an error to call this if has_pos() or is_2d() returned false.
Definition at line 471 of file transformState.I.
◆ get_rotate2d()
|
inline |
Returns the rotation component of the 2-d transform as an angle in degrees clockwise about the origin.
It is an error to call this if has_components() or is_2d() returned false.
Definition at line 483 of file transformState.I.
◆ get_scale2d()
|
inline |
Returns the scale component of the 2-d transform.
It is an error to call this if has_components() or is_2d() returned false.
Definition at line 504 of file transformState.I.
◆ get_shear2d()
|
inline |
Returns the shear component of the 2-d transform.
It is an error to call this if has_components() or is_2d() returned false.
Definition at line 515 of file transformState.I.
◆ get_uniform_scale()
|
inline |
Returns the scale component of the transform, as a single number.
It is an error to call this if has_uniform_scale() returned false.
Definition at line 439 of file transformState.I.
◆ has_components()
|
inline |
Returns true if the transform can be described by separate pos, hpr, and scale components.
Most transforms we use in everyday life can be so described, but some kinds of transforms (for instance, those involving a skew) cannot.
This is not related to whether the transform was originally described componentwise. Even a transform that was constructed with a 4x4 may return true here if the matrix is a simple affine matrix with no skew.
If this returns true, you may safely call get_hpr() and get_scale() to retrieve the components. (You may always safely call get_pos() whether this returns true or false.)

◆ has_identity_scale()
|
inline |
Returns true if the scale is uniform 1.0, or false if the scale has some real value.

◆ has_mat()
|
inline |
Returns true if the transform can be described as a matrix.
This is generally always true, unless is_invalid() is true.
Definition at line 368 of file transformState.I.
References is_invalid().
◆ has_nonzero_shear()
|
inline |
Returns true if the shear component is non-zero, false if it is zero or if the matrix cannot be decomposed.
Definition at line 358 of file transformState.I.
◆ has_pos()
|
inline |
Returns true if the transform's pos component can be extracted out separately.
This is generally always true, unless the transform is invalid (i.e. is_invalid() returns true).
Definition at line 290 of file transformState.I.
References is_invalid().
◆ has_quat()
|
inline |
Returns true if the transform's rotation component can be extracted out separately and described as a quaternion.
This is generally true only when has_components() is true.
Definition at line 310 of file transformState.I.
References has_components().
◆ has_scale()
|
inline |
Returns true if the transform's scale component can be extracted out separately.
This is generally true only when has_components() is true.
Definition at line 319 of file transformState.I.
References has_components().
◆ has_shear()

Returns true if the transform's shear component can be extracted out separately.
This is generally true only when has_components() is true.
Definition at line 349 of file transformState.I.

◆ has_uniform_scale()
|
inline |
Returns true if the scale is uniform across all three axes (and therefore can be expressed as a single number), or false if the transform has a different scale in different dimensions.
Definition at line 339 of file transformState.I.
◆ hpr_given()
|
inline |
Returns true if the rotation was specified via a trio of Euler angles, false otherwise.
If this is true, get_hpr() will be exactly as set; otherwise, it will return a computed value.
Definition at line 270 of file transformState.I.
◆ is_2d()
|
inline |
Returns true if the transform has been constructed entirely using the 2-d transform operations, e.g.
make_pos2d(), and therefore operates strictly in two-dimensional space on X and Y only.
Definition at line 227 of file transformState.I.
◆ is_identity()
|
inline |
Returns true if the transform represents the identity matrix, false otherwise.
Definition at line 197 of file transformState.I.
Referenced by CollisionLevelState< MaskType >::apply_transform(), CullTraverserData::apply_transform(), and PT().
◆ is_invalid()

Returns true if the transform represents an invalid matrix, for instance the result of inverting a singular matrix, or false if the transform is valid.
Definition at line 207 of file transformState.I.
◆ is_singular()

◆ operator !=()
|
inline |
◆ operator==()
| bool TransformState::operator== | ( | const TransformState & | other | ) | const |
Tests equivalence between two transform states.
We use this instead of compare_to since this is faster, and we don't need an ordering between TransformStates because we use a hash map.
If uniquify_matrix is true, then matrix-defined TransformStates are also uniqified. If uniquify_matrix is false, then only component-defined TransformStates are uniquified, which is less expensive.
Definition at line 186 of file transformState.cxx.
References get_mat.
Referenced by operator !=().
◆ quat_given()
|
inline |
Returns true if the rotation was specified via a quaternion, false otherwise.
If this is true, get_quat() will be exactly as set; otherwise, it will return a computed value.
Definition at line 280 of file transformState.I.
◆ unref()
|
virtual |
Explicitly decrements the reference count.
Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete().
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is true if the new reference count is nonzero, false if it is zero.
Reimplemented from ReferenceCount.
◆ write_datagram()
Writes the contents of this object to the datagram for shipping out to a Bam file.
Reimplemented from TypedWritable.

The return value will be normalized if a normalized quaternion was given to the constructor (or if the quaternion was computed implicitly); it will be non- normalized if a non-normalized quaternion was given to the constructor. See also get_norm_quat().
It is an error to call this if has_components() returned false.
