Fragmentum - Mesh fragmentation shader

Thanks

 

I am finishing working on Fragmentum 2 with sm2 and sm3 support.
Here are some images of the shader running on my Kindle Fire (android 2.3).
Current scene contains about 22.000 triangles.



You can try test build (.apk) on your mobile device.

Is Fragmentum 2 going to be a new product? I just bought Fragmentum before seeing there would be a new one.

 

Fragmentum 2 will be free update.

 

Fragmentum 2 will be available in several days.
It has sm2 and sm3 support. No DirectX 11 any more

 

Wait a minute!. works with Dx9/10 and OpenGL?

 

Exactly

 

Fragmentum seems very cool and i may buy it, but the current free project does not seem to work on Skinned Meshes. Does only the full version work with skinned meshes or is this something that is added to Fragmentum 2?

 

SkinnedMesh renderer works only with full version and only with dx11.

 

Fragmentum 2 (beta) has been released
Now it works with sm2, sm3 and of course with dx11.

We have been following Fragmentum for a while now and your progress is just remarkable. We currently are in need of these features for one of our mobile games. With this new update, do you guys have any ideas on when it will be mobile friendly, and exactly what type of mobile devices will be able to handle it? Thanks!!

 

With new Fragmentum 2 you can choose sm2, sm3 or sm5. So for mobiles you can use sm2 version. Fragmentum 100% works per vertex. More vertexes, more calculations . I made all key features of Fragmentum optional, in this case you can also control how "heavy" your shader would be.

Here is scene with about 22.000 triangles runing on Kindle Fire.

 

o wow, looking good! Ok cool, well this is something we will have to purchase soon!

 

Little example of Fragmentum 2.

Try webplayer

Shader in current scene is one of the "heaviest". Full forward rendering (directional and point lights per pixel) and with fragmenting shadow casting/receiving.

 

Hi!

Does Fragmentum 2 work on OSX? I see the free version doesn't..

 

Fragmentum 2 works on all platforms
Free version is only for DX11.

Try Statues deconstruction web player

 

Perfect, thanks!

One final question - do you know if there's any issues with Fragmentum 2 and Oculus Rift?

 

I do not have OR, but there shouldn't be any problem. Fragmentum is just a shader. Cool shader 8)

 

Hi!
Demo's are really impressive, so i thinking about purchasing, but there is one thing i would like to ask:
I saw objects divided mostly by triangles. But in my project i need objects to "construct from nothing" from specific parts. At least quads/rectangles if there is no other options.
Can i configure shader for quad based(or define some geometry parts) effect?

 

Hi,
In Unity mesh is constructed by triangles, Fragmentum uses that triangles to create fragmentation effect. Quads/Rectangles are not supported yet.
To add more "non triangle" appearance, I have added cutout shader to the package. Cutout effect is only applied to the fragmented parts of the mesh.

 

// Before start Fragmentum script prepares mesh for shader - generating some additional data and thus rebuilds it (only once).

If i understand correctly, with "cutout shader" Fragmentum script makes these fragmented parts on "preparing stage" by its own algorithm and then uses them as "parts" at final effect(instead of triangles)?

 

Fragmentum script rebuilds mesh and generates some data in a very specific format required by the shader. All meshes which have Fragmentum shader, require Fragmentum script attached. Cutout shader also fragments mesh by triangles, but pixel shader adds more "holes" to the final rendered effect.
Cutout effect is completely separate from the fragmenting effect, which creates Fragmentum.

 

Thanks, now it's clear

 

Fragmentum 2.1 has been released.

List of new features and improvements:
• Fragmentum has been completely redesigned and rewritten.
• New Fragmentum script prepares and rebuilds mesh for Fragmentum faster and much more accurate, according mobile shaders request
• New improved Fragmentum shader generator.
• Added shader auto recompile option.
• Added multiple object editing support.
• New improved Framgentum material editor.
• Added Fragmentum Influence global controller.
• Added Fragmentum Influence randomizer.
• Added Displace amount randomizer.
• Added new rotation type: Around custom point.
• Improved Radial Displace and Fragments scale.
• Added option to switch shader to double sided.
• Added option to calculate light per vertex, instead of per pixel.
• Pow function for Fragmentum Area Texture now is optional.
• Added easy shader type changer.
• Shader type now is visible inside material editor and inspector.
• Added Fragmentum Influence slider inside material editor.
• Main Color and Reflection Colors now are optional.
• Fixed main bugs for mobile shaders:
• Fragments stretching when using Fragment Area texture.
• Light calculation for sm2 shaders.
• Reflection vector calculation for sm2 shaders.
• Fragmentum native shaders now are hidden and does not require compilation when importing into new project.
• Many other micro optimizations and improvements.

• New Documentation and example scenes

• Fragmentum Free has been updated. It contains several sm2 version shaders instead of DX11. Does not contain Fragmentum shader generator.

Note: New Fragmentum is not compatible with the old version, but it is easy to recompile new shader with Fragmentum shader generator.

 

Congratulations, Great tool

 

Hello,

I am wondering if it is possible have a game object use a directional displace to fragment in and out just through with script? Currently I am trying to do this by switching models, which isn't very effective. I was hoping to look at that sculpture demo, but it wasn't included with the update.

Any help would be appreciated.

Keep up the good work.

 

Hi,

Fragmentum script has public functions to update activators, displace and rotations.
• public void UpdateActivatorPlane(Vector3 _activatorPlanePosition, Vector3 _activatorPlaneNormal);
• public void UpdateActivatorSphere(Vector3 _activatorSpherePosition, float _radius);
• public void UpdateDisplaceDirectional(Vector3 _direction);
• public void UpdateDisplaceRadial(Vector3 _pointPosition);
• public void UpdateRotateCustomPoint(Vector3 _pointPosition, Vector3 _pointNormal);

You can manually update any data in material, but first you must get Fragmentum material - GetMaterial();

As for sculpture demo, there are two separate objects but with similar Fragmentum parameters.
• Activator - Plane
• Displace Type - Directional
• Scalable fragments
• + some randomizes

Anubis parameters and activator position/rotation


Venus parameters and activator position/rotation



Difference is activators rotation (normal direction) and "Displace Amount" value.

 

Hi,

This shader looks great! I'm developing something for mobile and I have a couple of questions.

1. I downloaded the latest Fragmentum free to test since I read that the free version supports mobile shaders. However, when I deployed it to my Samsung S3 the meshes were solid and pink in all of the example scenes, even the simple scene. Is there a missing step to get it to work on mobile?
2. Would this work with a skinned mesh renderer? I.e. can I animate my mesh and have the effects still apply?

 

Hi,
1. Fragmentum Free does not contain mobile(gles) shaders. DX11 shaders were replaced with sm2 shaders.
As Fragmentum Free is without Fragmentum shader generator, shaders are precompiled and you can not generate shaders with gles support.
2. Only DX11 shaders can fragment skinned mesh.

 

So will this work on Macs? And how is indie different?

 

Hi!

I recently bought fragmentum pro - very cool tool! I have a question: I want to create an effect that should make certain parts of an invisible mesh to become visible. By moving a sphere attractor towards the invisible mesh the triangles that collide with the attractor should appear (the effect should be within a limited spherical area).
Until now I have achieved a kind of inverted effect: the triangles within the influence of the attractor disappear while the mesh is visible (see screenshot). Is there an easy way to achieve this effect?

 

@MikeLan
I think you can try negative value for sphere activator radius.
Dragging activators sphere's radius handles inside editor does not allow entering negative values, so just type it manually.

 

Thanks a lot - that solved the problem!

 

I can see on a graph that Indie version doesn't support deferred and forward rendering, but I suppose it does as a free version does, am I right?
If it works with deferred, does also image effects work (SSAO) in indie version?

 

Indie version can be used in Forward and Deferred rendering, but it supports only one directional light.
Currently not all image effects can be used with Fragmentum, as they can not see vertex displacement.

 

Fragmentum 3 (for Unity 5 only) brings lots of new features and improvements.

There is no more shader groups (Mobile, SM2, SM3, DX11).
Fragmentum 3 runs on all platforms and devices using just one shader.
Built in fallback system.
Fragmentum 3 runs inside Editor (not only in Game mode).
Added memory management system, which dramatically reduces memory usage.
Skinned Meshes - YES
Specular and Bumped effects - YES
Image based lighting and Spherical harmonics.
Mesh vertex color.
New improved shadow casting/receiving system.
Support of non-uniform scaling meshes.
New fragments rotation effects: LookAt target and LookAt Direction.
New mesh fragmentation options: Triangle, Quad, Smooth Group, Material ID, Compound Mesh.
Fragments emission and glow effects.
and many other cool features.

Completely new core of Fragmentum 3 brings new level of optimization.
Fragmentum 3 reuses already fragmented meshes, that dramatically reduces memory usage and avoids mesh fragmentation calculations.

Current scene contains about 800 tree mesh. Current version fragments all meshes individually, while Fragmentum 3 fragments only one of them.
Compare mesh count and used memory.





Currently Fragmentum divides mesh into triangles and manipulates them.
In Fragmentum 3 will be additionally available 3 new mesh fragmentation options.

1. Fragment mesh using its smooth groups.


2.Fragment mesh by its own compound meshes.


3. Fragment mesh by its material ID.



Skinned meshes work with all fragmentation types.

Hi!

I am really impressed by your work - congrats!
Based on your shader I created a small prototype called "Fractile". In the game prototype the player is confronted with lost memories - your shader was very helpful in this context!
The game mainly focuses on exploration and uses the Tobii EyeX Eytracker (http://www.tobii.com/buy-eyex?gclid=CKGusvjw78ACFUoUwwodNrAA3A) in combination with your shader. Based on the current gaze postion of players (in other words: where you currently looking at) NPCs will appear.
How it was done: I used the first person shooter prefab in Unity, parented a fragmentum helper (negative attraction value) several meters in front of the camera, and let the gaze position drive the current position of the helper.

In order that you can get a better impression I made a short video that shows the prototype (as well as a second one):

By the way - I have a feature request: it would be really awesome if the shape of the attractor could be defined - currently only a sphere and a plane can be selected. Custom shapes would really help to improve my game prototype
as I could create shapes that represent the players's view (camera) angle.

All the best,

M.

 

@MikeLan
Thanks. I am very interested to see projects where my shaders are used and hear opinions and suggestions about them. And good luck with your work.

Hi,

One question; When i buy the pro version now, does this also includes the future planned Fragmentation 3 (or a discount) when it gets released?

Thanks,

G

 

@gpvd
Fragmentum 3 will be free update.

 

Ok, sold!

 

Hello,

Recently i bought both Flow and fragmentation from you. Great packs.
I'm a bit curious; Do you have an eta of the upcoming fragmention 3?

Greetz,
G

 

@gpvd
Fragmentum 3 requires Unity 5, so it will be available after releasing Unity 5.



VacuumShaders

 

Ok,
tnx for the info.

Greetz,
G

 

Hi, i have this awesome asset, but im trying to use it on a large mesh. When i import the mesh Unity splits it into submeshes, but does so with more triangles than Fragmentum can handle. Do you know if there is a way to limit the triangle count on import so i can resolve this problem?
Thanks!
-- Judy

 

@radjudy
Unity can handle max 65000 triangles per mesh. if it has more vertices Unity will split it into sub meshes.
Fragmentum can handle max 21000 triangles per mesh.
There is no built-in tool in Unity to reduce triangle count. You have to manually edit your mesh in 3D modeling program - Maya, 3ds Max, Blender.



VacuumShaders

 

Can this be used in conjunction with the Unity 5 standard shader?

 

Currently no. I will be able to add Unity 5 features after releasing Unity 5.

 

Hey! This plugin is awesome! But I'm getting an error when building for iOS. It is saying "cross compilation job VacuumShaders.Fragmentum.dll failed"

Any advice?
