This should probably have a note that Minie is a high-powered binding around Bullet - that’ll look the most impressive to someone who’s not familiar with it, as Bullet & PhysX are the industry standard in physics engines.

8Keep123 · May 10, 2020, 4:01pm

Better to use the term Hardware Skinning under animation

ItsMike54 · May 10, 2020, 4:10pm

Maybe mention that there are also plenty of helpful demos and Hello— tutorials available in order to help new people get started using these features.

jayfella · May 10, 2020, 4:39pm

I should probably put that in our “getting started” page.

Ali_RS · May 10, 2020, 4:41pm

Yeah, and probably a note on Minie “soft body” supporting as well.

jayfella · May 10, 2020, 4:47pm

I’ve updated the main post - starting to look pretty impressive

Ali_RS · May 10, 2020, 4:51pm

Note, I just updated my post, added “CallMethod” in Stock Tweens section

Ali_RS · May 10, 2020, 4:58pm

I think this one is also very well deserved to be included under
Networking

SimEthereal : A high performance library for real-time networked object synching.

jayfella · May 10, 2020, 4:59pm

Yeah. I agree. I also forgot Lemur. Are we still actively promoting nifty, or should I just quietly not mention it…?

Ali_RS · May 10, 2020, 5:00pm

Yes, not mention it, please…

Ali_RS · May 10, 2020, 5:15pm

Note, JME 3.3 is 1.8+ actually.
Gltf loader in JME 3.3 uses Base64 decoder added in Java 8

              addToCache("buffers", bufferIndex, data, buffers.size());
              return data;
          
          }
          
          protected byte[] getBytes(int bufferIndex, String uri, Integer bufferLength) throws IOException {
              byte[] data;
              if (uri != null) {
                  if (uri.startsWith("data:")) {
                      //base 64 embed data
                      data = Base64.getDecoder().decode(uri.substring(uri.indexOf(",") + 1));
                  } else {
                      //external file let's load it
                      if (!uri.endsWith(".bin")) {
                          throw new AssetLoadException("Cannot load " + uri + ", a .bin extension is required.");
                      }
          
                      BinDataKey key = new BinDataKey(info.getKey().getFolder() + uri);
                      InputStream input = (InputStream) info.getManager().loadAsset(key);
                      data = new byte[bufferLength];
                      DataInputStream dataStream = new DataInputStream(input);

I did not know that. This list is more useful than I thought it would be.

Ali_RS · May 10, 2020, 5:37pm

Scene Graph

Light Culling
Single Pass Lighting

a brief explanation I copied that from nehon’s article for anyone interested

It’s based on the observation that rendering a light that is not in the camera frustum or rendering an object for a light that doesn’t affect it is a waste.

jME now has a way to sort that out. On each frame, each light is checked once against the camera frustum and not rendered when it’s outside. Also each geometry is checked against each light in the frustum and only renderer if the geometry is in the area of effect of the light.

SINGLE PASS

The idea behind single pass is to send a list of light information to the shader and to compute all the lights contribution while rendering the geometry once.

jayfella · May 10, 2020, 5:46pm

Oh yeah. And we have light batching. Good one.

tlf30 · May 10, 2020, 5:50pm

Wow, since when did JME become such a powerful engine! ( Just kidding, it has been amazing for a long time!)

This is a very impressive list, even I am learning things about what features are available.

Ali_RS · May 10, 2020, 5:59pm

Some more on PBR

PBR
- Supported Probe Areas :
  - SphereProbeArea

jayfella · May 10, 2020, 6:07pm

I’m updating them as they are posted and adding the ones I remember as I go. @Ali_RS you are pretty well versed on what the engine can do!

asser_fahrenholz · May 10, 2020, 6:15pm

Zay-ES - really awesome entity system
