"pr": "14482",
"title": "Camera: Modify Camera Movement to work off of time, instead of frame rate",
"description": "This PR modifies all cameras to take the animation ratio (time to complete a single frame) and uses it to make all camera movements take the same amount of time as 60 FPS (AR of 1).\r\n\r\nUpdate: Since the animation ratio (ratio used to scale inertia and movement offsets) is only updated in `scene.render()`, we had to add a custom timing method for users that have a custom rendering loop/cadence. This PR also adds the following changes:\r\n\r\n- `PrecisionDate.Now` has been updated to be more efficient\r\n- The variable `constantAnimationDeltaTime` has been added so that users can change the delta time for testing purposes\r\n\r\nPGs Used to Test: \r\n- https://playground.babylonjs.com/#DLIIMQ\r\n- https://playground.babylonjs.com/#DLIIMQ#1\r\n- https://playground.babylonjs.com/#DLIIMQ#3\r\n- https://playground.babylonjs.com/#DLIIMQ#4\r\n\r\nUpdate 2: Because we're now using 1000 / 60 (16.6666...) instead of 16 for the default constant animation ratio, some of the particle tests were broke. I've updated the PNGs against the new ratio.\r\n\r\nIn order to get the camera to move correctly, regardless of frame rate, I had to create a scaling factor that has to be multiplied against the offsets to be added. Because the math isn't quite clear as to how the scaling factor is found, here's an explanation:\r\n\r\nGiven the following variables:\r\n**r = initial offset\r\nn = inertia\r\na = relative inertia (with respect to frame deltaTime ratio; currentDeltaTime/standardDeltaTime) = n^t\r\ns = scale factor\r\nt = deltaTime ratio = currentDeltaTime/standardDeltaTime**\r\n\r\nLet's assume that the work to be done for our current frame rate can be represented as `scaleFactor * initial offset * relative inertia` `(inertia ^ (currentDeltaTime/standardDeltaTime))`. The equivalent amount of time could be represented as the sum _from (1 to t)_ of our `initial offset * inertia^x`\r\nsra = rn^t + ... + rn\r\n\r\nIf we factor out a common value of `rn`, we then have our initial value * the sum of a geometric series.\r\nsra = rn(n^(t-1) + ... + 1)\r\n\r\nWe can also factor out our initial offset\r\nsa = n(n^(t-1) + ... + 1)\r\n\r\nNext, we can substitute the closed formula for the sum of a geometric series\r\nsa = n((n^t - 1) / (n - 1))\r\n\r\nFinally, we set everything equal to s\r\ns = n((n^t - 1) / (n - 1)) / a\r\n\r\nLet's substitute a for n^t and clean up the fractions a bit\r\ns = n * (1/a) * ((a - 1) / (n - 1))\r\n**s = (n/a) * ((a - 1) / (n - 1))**",

"title": "Flow Graph Path Mapping",
"description": "# Changes\r\n - On the SetPropertyBlock, add a new parameter named `subString`, which represents a string that will be substituted by a node value if encountered between `{}`. For example, if the subString is `nodeIndex`, and the path is `/node/{nodeIndex}/`, when this node is activated, it will look into the nodeIndex socket, and substitute its value (which could be 0, then the path would be `/node/0`). This allows dynamic paths that are resolved based on the current state of the scene.\r\n - This change will be needed because of how the glTF Interactivity uses paths. In some cases, paths are defined as `/node/{nodeIndex}/property`, and we want these paths to be resolved at runtime.\r\n- The SetProperty node was changed to use a configuration object instead of sockets. The configuration object contains a string path (as defined in the context variables), and a string property, such as translation, rotation, etc.\r\n- I also moved the default serialization and parsing functions to a separate module, and added handling of vector values.\r\n- I also removed the variableDefinitions value, as it wasn't being used and made things more complex.",
