Hi, People usually love the Solid Particle System (aka SPS). Some of them sometimes ask for new features like the ability to extend it once created (coming soon) or for some extra speed by the ability to disable some computations. I made some study about how things could get faster. The short answer is : go to a lower lever in the implementation (replace the arrays of objects by typed arrays of floats, for instance), then use if possible other processes (GPU or workers). Well, here are the current status of my prototypes, so you can compare on your computer and browser the differences. The SPS of reference is really big, filled with 40K (yes, 40, 000 !) boxes and tetrahedrons. It's far more than we usually ask to a SPS with animated solid particles in the PG examples you could find in the forum posts. So your browser may suffer a bit ... Reference legacy SPS : http://jerome.bousquie.fr/BJS/test/spsReference.html Then comes the lighter typed array based version : http://jerome.bousquie.fr/BJS/test/spsBuffer.html As you can notice, it's a bit faster. Not only because of the usage of buffers/typed arrays, but also because it has less features than the legacy SPS for now. Let's go on... [EDIT] (from here, your need to have a browser with sharedArrayBuffer enabled) Here comes his new friend, the worker based SPS : http://jerome.bousquie.fr/BJS/test/spsProtoWorker.html This one is really faster. In this version, the particle logic (what the user want them to do) is still in the main thread and the worker only computes the transformations (the final vertex coordinates from the particle rotations, positions, scaling values, etc). At last, here's the second worker version : http://jerome.bousquie.fr/BJS/test/spsProtoWorker2.html It looks faster ... at least on my browsers. In this last version, the particle logic is deported in the worker. The main thread only carries for updating the mesh from the vertex buffers. In both worker versions, the worker computations are decoupled from the render loop. This means that the worker computes, then answers the main thread it has finished and this one just orders it to compute again, whatever the render loop is currently doing at this moment. The render loop just reads the data currently updated by the worker in a shared buffer (shared between the worker and the main thread) Next study step to come (not soon) : the GPU based SPS Please wait for a while until the frame counter stabilizes to the current average value if you run the tests.
http://playground.babylonjs.com/index.html#WP0JL8 I can rotate camera, but cannot move. `camera.cameraDirection` is changing, but camera position is not.
Hello everyone, I would like to know if it was possible to do the work of "Edges Renderer" in a worker thread? It's working really well for our projects but for some objects it can take really a lot of time in which the scene is completely stopping to respond. Any suggests?
