OMAUAPI void OMAUAPIENTRY omauInterpolate (  OMAUframe *  frame, OMAfloat  index )

omauInterpolate interpolates and stores the results in a frame from the currently bound chunk. If the frame references chunks with non-zero names, thouse chunks will be overwritten instead of creating new chunks. It is up to the caller to delete any chunks passed back in the frame. The bound chunk must have a type of OMA_KEYFRAME. Parameters: frame  The frame containing (possibly-zero) names of chunks to store the results in and used to pass back the names of the results. index  The index to use for interpolation. The integer part is used for the frame index selection. The fractional part is use for the weight. This cannot be less than zero.

OMAUAPI void OMAUAPIENTRY omauInterpolatefv (  OMAenum  trans, OMAfloat  weight, OMAsizei  count, const OMAfloat *  a, const OMAfloat *  b, OMAfloat *  c )

omauInterpolatefv interpolates using the specified algorithm and weight between two arrays of OMAfloats and stores the results in a third array. Parameters: trans  The "transition" algorithm to use. Can be one of the following: OMA_ROUND_DOWN Copy the first array to the destination array. OMA_ROUND_UP Copy the second array to the destination array. OMA_ROUND_NEAREST If the weight is less than 0.5, copy the first to the destination array. Otherwise, copy the second array to the destination array. OMA_LINEAR_INTERPOLATION Copy values that are evenly distributed based upon the weight between the first and second array to the destination array. OMA_CUBIC_INTERPOLATION Copy values that are cubicly distributed based upon the weight between the first and second array to the destination array. weight  A weight value with an intended range of [0,1]. count  The number of OMAfloats in each of the arrays. a  The "first" array. b  The "second" array. c  The "third", destination array.
