TransformBlend

from panda3d.core import TransformBlend
class TransformBlend

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

addTransform(transform: VertexTransform, weight: float)

Adds a new transform to the blend. If the transform already existed, increases its weight factor.

assign(copy: TransformBlend)TransformBlend
compareTo(other: TransformBlend)int

Defines an arbitrary ordering for TransformBlend objects.

getBlend(result: LMatrix4, current_thread: Thread)

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 updateBlend() to ensure that the cache is up-to-date before calling this.

static getClassType()TypeHandle
getModified(current_thread: Thread)UpdateSeq

Returns a counter which is guaranteed to increment at least as often as the result of getBlend() changes.

getNumTransforms()int

Returns the number of transforms stored in the blend object.

getTransform(n: int)VertexTransform

Returns the nth transform stored in the blend object.

getTransforms()list
getWeight(transform: VertexTransform)float

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

getWeight(n: int)float

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

hasTransform(transform: VertexTransform)bool

Returns true if the blend has the indicated transform, false otherwise.

limitTransforms(max_transforms: int)

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.

property modifiedUpdateSeq

Returns a counter which is guaranteed to increment at least as often as the result of getBlend() changes.

normalizeWeights()

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.

output(out: ostream)
removeTransform(transform: VertexTransform)

Removes the indicated transform from the blend.

removeTransform(n: int)

Removes the nth transform stored in the blend object.

setTransform(n: int, transform: VertexTransform)

Replaces the nth transform stored in the blend object.

setWeight(n: int, weight: float)

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

transformPoint(point: LPoint3d, current_thread: Thread)

Transforms the indicated point by the blend matrix.

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

transformPoint(point: LPoint3f, current_thread: Thread)
transformPoint(point: LPoint4d, current_thread: Thread)

Transforms the indicated point by the blend matrix.

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

transformPoint(point: LPoint4f, current_thread: Thread)
transformVector(point: LVector3d, current_thread: Thread)

Transforms the indicated vector by the blend matrix.

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

transformVector(point: LVector3f, current_thread: Thread)
property transformsSequence[VertexTransform]

Returns/Replaces the nth transform stored in the blend object.

updateBlend(current_thread: Thread)

Recomputes the internal representation of the blend value, if necessary. You should call this before calling getBlend() or transformPoint().

property weightsfloat

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.
