Live Raptor Mark Demo

Raptor Mark is a demonstration of what the Creature WebGL plugin is capable of.

Regular JS Demo

This demo shows 30 fully mesh deforming raptor characters running across the screen. This demo is using the CreaturePack Web format to deliver results that have high performance, great quality and yet compact in delivery size.

WebAssembly Demo

Unleash the power of high performance Web Assembly with the new CreaturePack WebAssembly runtimes!

Alt text The above demo uses advanced Delta Compression in CreaturePack to deliver high performance + quality animation with extreme compression ratios! This Raptor animation is only 230KB in size!

This second demo shows 200 (Not a Typo!!) mesh deforming raptor dinosaurs running across the screen! The demo is using the CreaturePack Web format similar to the JS version to deliver results that have high performance, great quality and yet compact in delivery size. However, with the new Web Assembly backend, the playback is even faster, capable of handling huge numbers of characters running live on your web browser. Even on moderately equipped PCs, this demo runs at a fluid 60 FPS. Make sure your browser has been updated to the latest version to take advantage of this exciting runtime.

Share your animations easily with the CreaturePack WebAssembly Widget

Alt text

The CreaturePack WebAssembly Widget allows you to easily share your exported Creature animations on your own personal webpage! The rendering core uses the powerful BabylonJS 3D WebGL Engine. This allows for beautiful rendering effects, including high quality soft-shadows and real-time 3D lighting. Head over to the WebAssembly folder for more info here.


The Creature Runtimes operate under 2 License types depending on whether you own a Licensed copy of Creature or not.

  • People who own a licensed copy of Creature: You use the standard Creature License included with the runtime code. TLDR: You are free to publish/modify/sell your product with the Creature runtimes without needing to state you are using the runtimes/put the copyright notice in your code/app. If you already have been using the Creature runtimes as a licensed owner of Creature, nothing changes :)

  • Everyone else: The runtimes are released under the very permissive Apache License :)

Both Licenses allow for private use and do not require any disclosure of your source code.


My character mesh in BabylonJS flickers/disappears

This is a BabylyJS renderer issue and has to do with the bounding box of the character. You can try setting mesh.alwaysSelectAsActiveMesh = true. Or refresh the mesh data and bounding box each frame. Please read the thread here

You can’t perform that action at this time.
