trying to get a static 3d image

[dhiru]

Hi, I have been trying to draw images (plus importing assets from my blender software) but what I want to do is create a "static" image of my scene to show on the browser so that it can run on more dumb terminals without requiring a lot of GPU power. 

I don't know if I am posing the question right but could you give me some pointers to how this can be done.

Thanks,

Hello,

you can either render your scene just once with scene.render() (And thus do not call engine.runRenderLoop).

If you want a screenshot of a scene to save it for later, we have BABYLON.Tools.CreateScreenShot:

Many thanks for this! -- just a quick stupid question; when I do not use the renderloop() is that in anyway "not" so stressful on the GPU; even though my scene is very complex (I guess it should right? or does the frames per second still work its way on the variables between the CPU and the GPU).

I realize my question might not be very intelligent nevertheless doesn't hurt to ask

Not calling the renderloop or just scene.render() will leave your GPU untouched  (If I've got your question correctly)

Actually the reason I am getting freaked out about the GPU is because I am planning to make a product that has 3 independent canvas's/engines,  showing three different angles of a Car. For the center one I plan to allow scene.render() only when the user is on a desktop. For low end devices, I would actually prefer to show a screen print (as light as an png/bmp); that way I eat up less battery and processing. 

I am not sure if I am over thinking all of this but I am not sure how I can generate an image from my Babylon.js page (or windows universal app) for low end devices.

All that said, I want to thank you/Babylon.js for even giving me any hope of doing any of this  -- I think it is one of the best frameworks I have come across; many thanks for your support.

No worry, your concern is real

But to be fair, if you call scene.render only once you don't even need to provide a screenshot. The scene.render() will run just once
