Constructor Detail

PMVMatrix

public PMVMatrix()

Creates an instance of PMVMatrix PMVMatrix(boolean useBackingArray), with useBackingArray = true.

PMVMatrix

public PMVMatrix(boolean useBackingArray)

Creates an instance of PMVMatrix.

Parameters:

useBackingArray - true for non direct NIO Buffers with guaranteed backing array, which allows faster access in Java computation.

false for direct NIO buffers w/o a guaranteed backing array. In most Java implementations, direct NIO buffers have no backing array and hence the Java computation will be throttled down by direct IO get/put operations.

Depending on the application, ie. whether the Java computation or JNI invocation and hence native data transfer part is heavier, this flag shall be set to true or false

.
