Matrix Interpolate - Arnold User Guide

Interpolates between different matrices based on the current time.

Matrix

The transformation matrix.

Type

Determines how to interpolate the matrix.

• time uses the current time inside the shutter range and allows you to get motion blurred matrices in the shading tree.
• value uses the specified value to interpolate between the matrices.

Transform Type

Specifies what type of motion the object has.

• Linear corresponds to the linear interpolation between matrices, similar to a shape's transform_type=linear parameter.
• Rotate about pivot gives a curved motion transform about the specified Pivot position. This is similar to the shape transform types of Rotate About Origin and Rotate About Pivot. (Note that not all Arnold plugins expose the shape transform type in their user interface.)

Pivot

The rotation pivot point for the Rotate about pivot transform type.
