Rendering things smoothly

[zerozhou]

I'm trying to rendering an entity which moves very fast.

But as the rendering is not doing all the time, when the entity move fast enough, I can see it "jump" from one place to another. Is there any idea that could do this? Or is it impossible as the system of mc?

 

A slow speed movement.

oooooooooooooooooooooooooooooo

The problem you are experiencing has to do with the fact that the entity is moving so fast that there isn't a renderframe for those in between spaces.

 

And because Minecraft lacks motion blur the entity will appear to skip over those areas entirely (as our visual system isn't given any hints about the entity moving through that area in order to fill in the gaps....literally).

 

You may not be able to solve this problem.

Thanks anyway.

Maybe I should try some other idea about the rendering.

Motion blur is really hard to fake.  The way it's done in 3D animation (films like Toy Story and games like Need For Speed XXVIIII) is to render the fast moving objects multiple times per frame, then average the results together.  For fast (render time) objects, you can get away with 2 additional renders: one 0.25 frames behind and one 0.25 frames ahead (depending on the speed and size of the object).  For accurate motion blur you might have to go up as high as six (!!!) additional renders.
