Detailed Description
A base class for any of a broad family of flt records that represent particular beads in the hierarchy.
These are things like group beads and object beads, as opposed to things like push and pop or comment records.
Member Function Documentation
◆ add_transform_step()
| void FltBead::add_transform_step | ( | FltTransformRecord * | record | ) |
Applies the indicated transform step to the net transformation applied to the bead.
Definition at line 123 of file fltBead.cxx.
◆ clear_transform()
| void FltBead::clear_transform | ( | ) |
Removes any transform matrix and all transform steps on this bead.
Definition at line 79 of file fltBead.cxx.
◆ get_num_transform_steps()
| int FltBead::get_num_transform_steps | ( | ) | const |
Returns the number of individual steps that define the net transform on this bead as returned by set_transform().
Each step is a single transformation; the concatenation of all transformations will produce the matrix represented by set_transform().
Definition at line 92 of file fltBead.cxx.
Referenced by FltToEggLevelState::set_transform().
◆ get_replicate_count()
| int FltBead::get_replicate_count | ( | ) | const |
Returns the replicate count of this bead.
If this is nonzero, it means that the bead is implicitly copied this number of additional times (for replicate_count + 1 total copies), applying the transform on this bead for each copy. In this case, the transform does *not* apply to the initial copy of the bead.
Definition at line 141 of file fltBead.cxx.
◆ get_transform()
| const LMatrix4d & FltBead::get_transform | ( | ) | const |
Returns the single-precision 4x4 matrix that represents the transform applied to this bead, or the identity matrix if the bead has not been transformed.
Definition at line 58 of file fltBead.cxx.
Referenced by FltToEggLevelState::get_synthetic_group().
◆ get_transform_step() [1/2]
| FltTransformRecord * FltBead::get_transform_step | ( | int | n | ) |
Returns the nth individual step that defines the net transform on this bead.
See get_num_transform_steps().
Definition at line 101 of file fltBead.cxx.
◆ get_transform_step() [2/2]
| const FltTransformRecord * FltBead::get_transform_step | ( | int | n | ) | const |
Returns the nth individual step that defines the net transform on this bead.
See get_num_transform_steps().
Definition at line 112 of file fltBead.cxx.
◆ has_transform()
| bool FltBead::has_transform | ( | ) | const |
Returns true if the bead has been transformed, false otherwise.
If this returns true, get_transform() will return the single-precision net transformation, and get_num_transform_steps() will return nonzero.
Definition at line 48 of file fltBead.cxx.
Referenced by FltToEggLevelState::set_transform().
◆ set_replicate_count()
| void FltBead::set_replicate_count | ( | int | count | ) |
Changes the replicate count of this bead.
If you are setting the replicate count to some nonzero number, you must also set a transform on the bead. See set_replicate_count().
Definition at line 151 of file fltBead.cxx.
◆ set_transform()
| void FltBead::set_transform | ( | const LMatrix4d & | mat | ) |
Replaces the transform matrix on this bead.
This implicitly removes all of the transform steps added previously, and replaces them with a single 4x4 general matrix transform step.
