IFlowGraphCombineMatrixBlockConfiguration

Interface IFlowGraphCombineMatrixBlockConfiguration

Configuration for the matrix combine blocks.

The matrix combine blocks now default to column-major input, matching Babylon's Matrix storage and the glTF/KHR_interactivity convention. This interface is retained so the inputIsColumnMajor option keeps being honoured; set it to false to feed row-major input.

BREAKING: the meaning of inputIsColumnMajor is inverted from previous releases, not just its default. Previously inputIsColumnMajor: true took the transposing path and the default (unset) treated input as row-major. Now the default (unset) is column-major, inputIsColumnMajor: false takes the transposing path, and inputIsColumnMajor: true is the straight (non-transposing) path. The unset behaviour is unchanged for graphs that never set the flag, but anyone who explicitly set true or false before now gets the opposite transform and should drop the flag (or flip it).

interface IFlowGraphCombineMatrixBlockConfiguration {
    inputIsColumnMajor?: boolean;
}

inputIsColumnMajor?
inputIsColumnMajor?: boolean

Whether the input is already in column-major order. Defaults to true.

Provide column-major input (the default) and omit this flag. Set to false only to keep feeding legacy row-major input, which is transposed into the matrix's column-major storage. Note the inverted meaning versus previous releases (see the interface deprecation note): a former inputIsColumnMajor: true no longer transposes, and a former false now does.
