示例1: applyTransformAnimation
static TransformationMatrix applyTransformAnimation(const TransformOperations& from, const TransformOperations& to, double progress, const FloatSize& boxSize, bool listsMatch)
{
TransformationMatrix matrix;
// First frame of an animation.
if (!progress) {
from.apply(boxSize, matrix);
return matrix;
}
// Last frame of an animation.
if (progress == 1) {
to.apply(boxSize, matrix);
return matrix;
}
// If we have incompatible operation lists, we blend the resulting matrices.
if (!listsMatch) {
TransformationMatrix fromMatrix;
to.apply(boxSize, matrix);
