► Wireframe shader - The Amazing Wireframe shader ◄

For the next update I will try to add: Wire transparency control vie texture and IBL.

 

When you think deliver an update?

 

@3DJayC
I am very busy now, but will try to manage new update this year.

 

Okay cool! Can't wait to see!

Thanks!

I am trying to use the "Unlit>Transparent>NoTex" shader and need to change the color of the wireframe on runtime. I am trying the:

renderer.material.SetColor("V_WIRE_COLOR", DesiredColor);

But it's not working. How do you do it?

 

It works. May be your alpha is zero, that's why you do not see it.

It works, thanks for the pointer

 

EDIT: Nevermind. got it fixed. Attached script to wrong object heh.

Panic over

Spoiler

Hihi, bought to use on Unity Pro Beta 5.0 but I don't see any Wireframes (sadface)

Is it not compatible?



As you can see the only wireframing is the default editor stuff.

Many thanks.

I'll tell you how it does with the Beta 5.0 and webgl



Thanks

 

I am interested in using the your wireframe shader on a mesh that I am updating on every frame. I am refreshing the points of the mesh in the Update() function. Could you tell me if this is possible? I bought the plugin today so I have the WireframeGenerator code.

 

@aopdenbosch
There is no problem if you just modify vertex position in the Update() function. But if you generate new mesh with new vertexes, then you should also generate new wire data for that mesh.

 

Hi Arkhivrag,

Did you update the shader to be control by an alpha map?

@3DJayC
Update will be available next week.

 

Ok thanks!

Let me know when it's updated

Hi Arkhivrag,

I modified my dynamic mesh code so the vertices are not generated on every frame. I am simply updating their positions. But.......I am having some problems even before I even get to that part of the code. I am having some problems in your "Generate" method the first time I call it with my code generated mesh. Unity just hangs and starts allocating memory.

Here is the code that I am using to generate my mesh on Awake(). Btw, I made sure that your code is called after this mesh is ready:

====================================================
void Awake()
{
int gridSie = 128;
MeshFilter myFilter = depthMesh.AddComponent<MeshFilter>();
Mesh myMesh = myFilter.mesh;
Vector3[] vertices = new Vector3[gridSize*gridSize];
Vector2[] uv = new Vector2[gridSize*gridSize];
Color[] colors = new Color[gridSize*gridSize];
float inc = 1.0f / (float)gridSize;
int i = 0;
for( float y = 0.0f; y < 1.0f; y += inc )
{
for( float x = 0.0f; x < 1.0f; x += inc )
{
vertices = new Vector3( x,y, 0.0f );
uv = new Vector2( x,y );
colors = new Color(0.5f,0.5f,0.5f);
i++;;
}
}

myMesh.vertices = vertices;
myMesh.uv = uv;
myMesh.colors = colors;

i = 0;
int[] triangles = new int[gridSize * gridSize * 6];
for ( int y = 0; y < gridSize - 1; y++ )
{
for ( int x = 0; x < gridSize - 1; x++ )
{
// First triangle
triangles[i++] = ( y * gridSize ) + ( x );
triangles[i++] = ( ( y + 1 ) * gridSize ) + ( x );
triangles[i++] = ( y * gridSize ) + ( x + 1 );

// Second Triangle
triangles[i++] = ( ( y + 1 ) * gridSize) + ( x );
triangles[i++] = ( ( y + 1 ) * gridSize) + ( x + 1 );
triangles[i++] = ( y * gridSize ) + ( x + 1 );
}
}

myMesh.triangles = triangles;
//myMesh.RecalculateNormals();
//myMesh.Optimize();
}

==========================================================
I was originally not generating the colors but I added them to see if that would help but it did not. Also the last two commented lines don't help either if I include them. So there seems to be a difference between a mesh created by editor and a mesh created in code when it comes to your code. Or, I am forgetting to add something crucial to my mesh before calling your generation code. May be you can help me out.

 

Neat little asset, not sure how I would benefit from this, but I've added it to my watch list. Keep up the good work ^^

 

@aopdenbosch
Are you sure your mesh is correct?
Add this lines at the end of your script to ensure that your mesh triangles are generated correctly

Code (CSharp):

1. for (int k = 0; k < triangles.Length; k += 3)
2. {
3.     if (triangles[k] == triangles[k + 1] ||
4.         triangles[k] == triangles[k + 2] ||
5.         triangles[k + 1] == triangles[k + 2])
6.     {
7.         Debug.LogError("Triangle " + k/3 + " is wrong!!!");
8.     }
9. }

triangle can not have two same vertexes

Hi Arkhivrag,

Thank very much. The triangle array that I was allocating was bigger than it needed to be. Once I fixed that problem the wiremesh rendered correctly. It looks awesome.

Thanks again for taking the time to look into this.

Regards,

-Augusto

Hi,

Better and better. Can you add two option :
a) The ability to display without drawing the wireframe. Yes, i know : this is a wireframe shader.
b) The possibility to replace the grey color by another one.

Imagine this image with the previous requirements. Will be cool no?!

 

@ZJP
a) The ability to display without drawing the wireframe
Check Wire Color parameter inside material editor. RGB defines wire color, A - its transparency.

b) The possibility to replace the grey color by another one
Check Gradient Color inside material editor. RGB defines gradient color, A - interpolates that color to Base texture.

My bad. It's a perfect example of the "RTFM" thing.

 

I actually was going to request bi-axial shading or capsule based... :\

I surely would love to be able to shade in two axes.
think "arm out to side" then "arm out in front."

- that would also suit a radial/spherical solve hence my other comment about capsules. (might not be too computationally expensive for a pure sphere?)

Anyways I can see you have been hard at it. Ill go check what you did before making ridiculous requests.

@ZJP I actually was also going to ask for a "Transparent -> Wireframe -> Opague" variant.
Took me two days to think it through and realise I could probably do that with that Alpha setting and the right texture.
So, yeah, not alone.


appreciate the update.

Oh, I think I spotted a typo in the shader titles.
"/Unlit/Additive"


EDIT: I must admit I do Search Replace:
VacuumShaders/The Amazing Wireframe/
for
Vacuum-Wireframe/
in the shader code, as the extra click bocomes tiresome.

Final question. This thing doesn't do shadows right?
Just checking. I never see any.
I suppose I could go check the code or unitys inspector analysis but never hurts to check.

Many thanks and Thanks for the amazing shader.

 

Update v1.31 available
Unity editor wireframe will not disturb any more, it can be hidden from material editor.

Looks like an awesome product - just (almost) something I need...
I would buy instantly if there were quad support.

 

struggling to get the new http://unity3d.com/unity/cloud-build system to swallow your shader mate, for the 5.0 web target.
(yup, your latest code)

Just comes up blank. With a "NOT SUPPORTED replacing with standard" error, tried every possible rendering path et cetera I could think of...

Do you have access to the http://unity3d.com/unity/cloud-build system yet?
Think you might have some headaches there is the future. Might be worth checking it out.

Word to the wise.

 

Quads would be great, but it's beyond shader. Need some headache at the script side.


@twobob
I do not have access to the CloudBuild. Thanks, I take note.

Thanks for the great shader Arkhivrag.

I have a question about the WireframeManager class. In my code I need to destroy and recreate wire frames for particular meshes (I am modifying the vertices array). In a previous version you had the WireframeManager accessible, but it has now been moved to the dll.

My code still works if I add WireframeManager back to TheAmazingWireframeGenerator.cs (my version of GetWire is called instead of the dll version), but I wonder if this will conflict with any other code that calls GetWire?

Perhaps you can expose a DestroyWireframe(Mesh _mesh) function in a future version?

 

Update v1.32 available.
Generating wireframe from script can be done by using
1. WireframeGenerator.Generate() - Generates and returns wireframed mesh.
2. WireframeManager.GetWire() - Generates(if it's necessary) and returns wireframed mesh. Also saves IDs of the meshes whose wireframe has been generated. If several meshes with same ID will require wireframe it will be generated only once for all of them.
Added WireframeManager.RemoveMesh() to remove mesh ID from manager and WireframeManager.Clear()

@People Pilot
I think your own function and class will not conflict with Wireframe code.

Shader error in 'VacuumShaders/The Amazing Wireframe/One Directional Light/Gradient/Transparent': redefinition of 'unity_LightmapST' at Assets/VacuumShaders/The Amazing Wireframe Shader/Shaders/Wire.cginc(39) (on d3d9)

Looks like it could be a name collision with

https://www.assetstore.unity3d.com/en/#!/content/4243
Amplify motion maybe.

Will go hunt.

EDIT: Hmm.. no obvious candidates...

I did find this in one of the other shaders...
// Upgrade NOTE: commented out 'float4 unity_LightmapST', a built-in variable
// Upgrade NOTE: commented out 'sampler2D unity_Lightmap', a built-in variable

Perhaps I can just elide this declaration?
Is there such a thing as a concept of namespace in shaders? I guess not.
It's been about 6 years since I touched them (Unity 2.5 era IIRC) Sigh, so much to remember, so little time.

Will play, I did note yours is a half4 not a float4

EDIT EDIT: I elided it. will see what damage that does. (It Now Builds Okay)



Seems okay

I personally am not using lightmapping with this project anyways at this point, nor probably going forward as it is procedural.

 

@twobob
Very little info to reproduce that "bug" on my side.
redefinition of 'unity_LightmapST' - It can not be redefined (declared only once and only if Unity uses lightmaps) ?
// Upgrade NOTE: - why did Unity upgrade shader and how it did that ?
Shaders can not have name collision and namespaces.
May be Unity has messed up something. If errors continues just let me know.

I just removed it. and now it works :\ ?

the ONLY change I made was to add the Amplify Motion plugin.

That is all the info I can give you?

Sorry mate

 

Sorry to resurrect, but does this come with the model viewer?

 

err I think it did.

 

Not a huge thing for me, I just really like the idea of having a model viewer for my personal portfolio, I have a few images up but images take time to do well, whereas model viewer is much nicer to have, plus it is interactive and potential employers can see the different texture layers used so they can see your workflow, which is a huge bonus in my books, and as that would be what I would mostly be using this for (and for temporary use in-game while on a build), this would be very useful, they seem very useful and not many people have them, I hate to steal the thread, so I made another one for this, if anyone knows how to adapt some code for a model viewer in 4.6, post in the link.

http://forum.unity3d.com/threads/unity-4-6-model-viewer.294162/

 

Hi,
Troll model is inside package.
Web demo scene with options controlling from gui is not included (it is not necessary, all parameters can be changed from material editor)
Camera rotation script for model view is not included. Script is inside Unity default packages "Mouse Orbit.js".

Hello I have bought this very well done and awesome shader thinking that it could paint all the polygon wireframe and also only the ones that are only on the edges and do not paint the triangular wires inside the edges, here below I have put an example I have made in Photoshop. What I want is to get the result made on the THIRD image.
Is there any possible to use this Wireframe shader to make the third result possible? How?


If it is not possible I would like to ask for a refund because if it ONLY paint ALL the wirframe polygons it is useless for me and I will not be able to use it.

I also have other more complex 3D models that are buildings and other objects, and I would like that ONLY be painted the EDGES SHAPE and not ALL the polygon wires that makes the 3D model.

I also would like to have a glow added to that wireframe line (I have Unity Pro) so I could get something like the logo name of the game Orborun

 

The store handles refunds, you would be better sending him a PM as the author agreeing could make it all go a bit faster and no one wants to wash their underwear in public.

You know, other than the "near" lines that last picture looks a bit like a Cartoon Shader (with a tight white outline).

So you could draw that in a few passes (mesh read in sub-parts of the various directions) and shade it that way.
You only show a single use case, so that is all I have to go on.
EDIT: Okay I see you added another use case. Thank you.

To be fair, the middle picture is the "Wireframe" picture, and the last one is more like a "Super Accurate Rim" shader or edge detection shader or something. I feel pretty sure someone asked this before, but I may be wrong.

 

@SpaceRay
Wireframe shader does what it is supposed to do. You are looking for edge detection shader, that feature is not available in Wireframe shader. I do not know how technically refund is done, but you can talk with Asset Store team and if they find refund reason valuable, they will give it.

First of all, apologies if this has already been requested or is already implemented - haven't had time to read the whole forum!

Is there a possibility that this shader could do an effect similar to the 'scanning refresh' effect in, for example, the ship viewer on the Star Citizen website where the vertices are momentarily brightened as a 'scanline' passes through the model?

Just realised - this post is a bit of a necro too!! Is this shader even still supported?

 

@nockieboy I think I know what you are talking about, but could you provide a link?
You will need to be a lot more specific to get an accurate answer, even if what you are looking for is what I am thinking.

 

@nockieboy
Wireframe shader is still supported. Can you provide the link of the effect you want, than I'll be able to answer.

Was trying to flip a skinned mesh- Is that tricky?- using the Vertex Color/Unlit/Transparent/Wire Only 2 Sided?
Tried renaming duplicate geometry and generating new vertex data on a negatively scaled skinned mesh root node.(human figure... was hoping to be able to get the memory benefits of duplicating and inverting)

 

I just upgraded to 5.0 and I can no longer see it from the Downloads section in my Unity store.

It seems to work fine though, any chance you can upgrade so it will be used in 5.0.

If I go to the store it asks me to purchase it again.

 

In the shader name symbol "2" means two/double not second. That shaders has no parameters like color and texture and just renders wireframe for as two/double sided.

Unity 5 currently is not fully supported. I have 7 assets on the Asset Store and I need time to convert them all.

The wireframe shaders works fine in Unity 5 except for when trying to make a windows standalone build. We get:

Shader error in 'VacuumShaders/The Amazing Wireframe/Unlit/Transparent/NoTex 2 Sided': variable 'o' used without having been completely initialized at Assets/VacuumShaders/The Amazing Wireframe Shader/Shaders/cginc/Wire_Vertex.cginc(169) (on d3d9)

and

Ah yeah, I meant to mention that... Fixed it in my local version and forgot.
Nice one for the prompt fix-up.

 

This an interesting little package... I was looking for ways to draw wireframes in game view and was directed to this. I was wondering if this would work with something like Alloy or the U5 standard shader
