  1. Hi! I'm hoping that someone else has tried this already. I want to reshape the texture in a projecting spotlight. I tried adjust the uScale and vScale on it and they did not work for me. I tried the same texture on a surface and obviously got the result I was looking for. I'm looking for an effect where I can reshape the spotlight into other shape than circle really. I think I figured out why it is shaped like a circle because of the math involved. My idea was actually to produce a video projector scene very much like this PG here (Hit Run after loading for first time, otherwise video won't play): https://playground.babylonjs.com/#CQNGRK#7 I basically pasted in the video texture from elsewhere and thought to make a drive-in scene from that. Then the spherical light really would not do there. Help? Thanks!
  2. I have a game with a lot of containers and sprites. I used GPU-Z for testing. After I replaced all containers and sprites with 2D, GPU load decreased on 20% What is the reason of that? What is the difference between container / sprites and container2d / sprite2d?

    Need advice for some project

    Hi guys. I want to create a effect in PIXI, that looks like first frames in this video -> http://hubblesite.org/video/513/news_release/2006-01 (stars shooting/flying by). What would more experienced PIXI'oniers advice to achieve such effect? Performance is critical, I want it also to work on mobiles. For now I'm thinking: 1) Particle container, that's for sure? Maybe with some 1-3 star sprites? 2) Projection plane for start movement? Or just calculate it with some custom simple logic?
  4. Hey all, Sorry to bother you with yet another shadow related question, but i'v ran into trouble. I'm doing some tests with dynamic world creation and shadows. So i'm using directional light to cast shadows, but for every mesh i import the shadows get more and more "crispy". This is fine as long as i keep light.autoUpdateExtends as false.., BUT i ran into another issue; the "shadow projection" from the light is very slim and parallel with light angle, i simply don't know how to enlarge the shadow projection so it would fit with camera view. Any ideas? - eljuko EDIT: added image. As u can see, the shadows from the rocks doesn't fit in the projection.

    Projective Texturing

    Hello everyone... sorry for another noob question but I am learning and loving babylon! I am curious if babylon can project a texture onto multiple objects... similiar to how this is: http://playground.babylonjs.com/#1215MA but I want to be able to project from a specific point in the scene.. not from the active camera but maybe another camera in the scene? Thanks!
  6. Hello guys, I'm doing an app to control objects via a Kinect sensor. I finally managed to control two hands (they are just images) on the screen, and the next step is to be able to put a Hand in front of a sphere and allow this sphere to follow the position of the hand. My hand is just an Image on the screen I move it by changing his left and top css properties, and my problem is how to know when my hand "touched" the sphere. I've tried with BABYLON.Ray(hand.x,hand.y) but it's like the ray is pointing somewhere I don't know, and the "touch" occurs somewhere far from the sphere. Any ideas ? Thank you in advance.
