how to convert 3D obj file to particles in three.js

I'm trying to play around with particles in three.js but, there's a problem with converting obj file (3D model) into particles in three.js. The following is the code snippets. I tried but, all failed.

Is there anyone who can help correcting the errors or provide with any examples of getting vertices/particles from a 3D model in obj?

Thanks a lot.

QUESTION

Unity Curve Evaluate is normalised time, or what units?

Asked 2021-Sep-28 at 17:36

The Evaluate function on an animation curve gets a value at a time.

https://docs.unity3d.com/ScriptReference/AnimationCurve.Evaluate.html

But it's not clear (to me) what time base or units are used.

For ParticleSystem.MinMaxCurve, this is explicitly described as being evaluated as a normalised 0 to 1 range of values of the curve's duration:

https://docs.unity3d.com/ScriptReference/ParticleSystem.MinMaxCurve.Evaluate.html

Normalized time (in the range 0 - 1, where 1 represents 100%) at which to evaluate the curve. This is valid when ParticleSystem.MinMaxCurve.mode is set to ParticleSystemCurveMode.Curve or ParticleSystemCurveMode.TwoCurves.

UPDATE:

For those considering performance: AnimationCurve's Evaluate is very fast in the traditional sense of Unity's MonoBehaviour world, having an inbuilt means of caching the lookup for the surrounding keys, and retention of the last position evaluated, too. Especially fast in loops of evaluation, because of this. Highly old school optimised, by Unity.

However, ParticleSystem.MinMaxCurve's evaluate benefits from and is part of the Jobs friendly updates to the UnityEngine.ParticleSystemJobs features.

In small usages (around 1000 evaluation steps or less), they're about the same. But with Jobs and lots of fine grained evaluation (more than 10,000), the MinMaxCurve gets ahead.

...

ANSWER

Answered 2021-Sep-20 at 11:30

It uses 0 to 1 in the most cases but depends completely how you configure and use yours ... you can easily extend an AnimationCurve with keyframes before 0 and beyond 1.

You can however get the duration of your AnimationCurve so basically you can normalize down any animation curve to a "time" value between 0 and 1 using

I am trying to use a ParticleSystem for Decals as a cheap alternative but am unable to align the particles with all normal surfaces.

This is the nearest I've got that gets all axis correct except for an inverted x axis. (I can see it's the wrong way round on building windows)

Unity 2d : Objects being reinstantiated on scene reload after being destroyed

So I'm creating a top down arena battler type game, and I want you to be able to restart the game by pressing R.

When I press R, the whole scene resets as it should, except all the enemies that were previously instantiated (and then destroyed) are spawned again, all at once.

ANSWER

Answered 2021-Sep-19 at 07:27

The problem is in Time.time, it is time since the start of the application, not since the start of the scene. So if you were in the game 30 secs, Time.time is 30 secs. If you reload the scene it is still 30 secs.

You have to count the time passed since entering the scene. Then it won't respawn all the enemies on scene reload.

Any good reason why your methods are all nested under the OnCollisionEnter as locel functions? ;)

Unity's messaging system doesn't find local functions - since they literally only exist for this one method - but works only with class level methods.
