TransformBlend¶

class TransformBlend¶

This defines a single entry in a TransformBlendTable. It represents a unique combination of VertexTransform pointers and blend amounts.

TransformBlend.__eq__()¶

TransformBlend.__init__()¶

TransformBlend.__lt__()¶

TransformBlend.__ne__()¶

TransformBlend.add_transform()¶: Adds a new transform to the blend. If the transform already existed, increases its weight factor.

TransformBlend.assign()¶

TransformBlend.compare_to()¶: Defines an arbitrary ordering for TransformBlend objects.

TransformBlend.get_blend()¶

Returns the current value of the blend, based on the current value of all of the nested transform objects and their associated weights.

You should call update_blend() to ensure that the cache is up-to-date before calling this.

static TransformBlend.get_class_type()¶

TransformBlend.get_modified()¶: Returns a counter which is guaranteed to increment at least as often as the result of get_blend() changes.

TransformBlend.get_num_transforms()¶: Returns the number of transforms stored in the blend object.

TransformBlend.get_transform()¶: Returns the nth transform stored in the blend object.

TransformBlend.get_weight()¶

Returns the weight associated with the nth transform stored in the blend object.

Returns the weight associated with the indicated transform, or 0 if there is no entry for the transform.

TransformBlend.has_transform()¶: Returns true if the blend has the indicated transform, false otherwise.

TransformBlend.limit_transforms()¶: If the total number of transforms in the blend exceeds max_transforms, removes the n least-important transforms as needed to reduce the number of transforms to max_transforms.

TransformBlend.normalize_weights()¶: Rescales all of the weights on the various transforms so that they sum to 1.0. It is generally a good idea to call this after adding or removing transforms from the blend.

TransformBlend.output()¶

TransformBlend.remove_transform()¶

Removes the nth transform stored in the blend object.

Removes the indicated transform from the blend.

TransformBlend.set_transform()¶: Replaces the nth transform stored in the blend object.

TransformBlend.set_weight()¶: Replaces the weight associated with the nth transform stored in the blend object.

TransformBlend.transform_point()¶

Transforms the indicated point by the blend matrix.

You should call update_blend() to ensure that the cache is up-to-date before calling this.

Transforms the indicated point by the blend matrix.

You should call update_blend() to ensure that the cache is up-to-date before calling this.

Transforms the indicated point by the blend matrix.

You should call update_blend() to ensure that the cache is up-to-date before calling this.

Transforms the indicated point by the blend matrix.

You should call update_blend() to ensure that the cache is up-to-date before calling this.

TransformBlend.transform_vector()¶

Transforms the indicated vector by the blend matrix.

You should call update_blend() to ensure that the cache is up-to-date before calling this.

Transforms the indicated vector by the blend matrix.

You should call update_blend() to ensure that the cache is up-to-date before calling this.

TransformBlend.update_blend()¶: Recomputes the internal representation of the blend value, if necessary. You should call this before calling get_blend() or transform_point().
