Gizmo of transformation

[Dad72]

Hello,

 

How to display a gizmo of transformation when one selects an object (in local mode and global) ?
This will be important for my editor of scene.

Thank You

[GameMonetize]

Hello,

 

right now you have to do that by yourself (with scene.pick and basic shapes) but in a really near future, we will release a sample called "Babylon Editor" with required code to create gizmos

[Dad72]

Good news for the 'Babylon Editor'.  When you say near future, this is approximately how long.
I am curious to see the different ways of doing it.

 

Thank You

[GameMonetize]

Two weeks max

[Dad72]

That's great! I will wait. Thank You Deltakosh

[Dad72]

I have a question concerning 'Babylon Editor'. will present it also the ability to display on a terrain/ground the radius of the brush.

 

like this for example: (or just the part in red.)

 

[GameMonetize]

No right now this feature won't be supported

[Dad72]

And how do i get this feature? This is called how? I would like to do a google search

[GameMonetize]

Vertices selection?

[Dad72]

This is difficult to achieve. I do not know the do. it's a pity

[GameMonetize]

This is clearly not a simple thing to do but if you look at WorldMonger demo, you can just add vertex color to the ground mesh and play with the color

[Dad72]

Thank you for the info.

I suppose that is in this method that I must add a color : WORLDMONGER.ElevationControl.prototype.attachControl = function (canvas)

In this._onBeforeRender or this._onPointerMove ?

[GameMonetize]

You have to update the ground mesh: right now it contains position, normal and uv

 

I suggest adding also a color

[Dad72]

I think that I will abandon, its fact four day that I have the nose in the handlebar. I do not know where to look, I not understand the code of WorldMonger, i don't know add a color. I despair.
I want good to add a color, but where and how? I want good to update the ground, but how? I won't get there without more precise help.

 

Thanks for your time

[Dad72]

Is this that its features will be presented in the future?

- Gizmo of transformation on the objects
- Brush with radius of color
- Smoothing of the terrain
- Change of texture of ground.

- Painting of the grass

- LOD ground (low, medium, higth)

That is what is missing to WorldMonger for having a terrain editor really cool. Please.

 

Thank You Deltakosh
 

[GameMonetize]

Gizmo: Yes (next week in everything comes together)

Brush: no

Smoothing: already present in worldmonger demo

Painting of grass: too specific

LOD: yes

[Dad72]

Ok, thank you for the answers.

I am not able to do what I wanted to for the vertexes selected of color. So I have made with the particles that i've edit for me closer of what I wanted to do.

 

The changes made:

- The box and the numbers of particles increases when resizing the brush.
- The particles stops instantly when we do clicked more on the ground.

- The elevation of the ground is slower for more precision. and add a slider to regulate the speed of elevation.

- Readjustment of the position of the particles during the click on the ground.

 

I share what I have done:

 

In the constructor

   WORLDMONGER.ElevationControl = function (ground)        this._ground = ground;        this.radius = 5.0;                this._invertDirection = 1.0;        this.heightMin = -5.0;        this.heightMax = 30.0;         this.speed = 0.1;                              var particleSystem = new BABYLON.ParticleSystem("particles", 2700, ground.getScene());        particleSystem.particleTexture = new BABYLON.Texture("ba.jpg", ground.getScene());        particleSystem.minAngularSpeed = 0;        particleSystem.maxAngularSpeed = 0;        particleSystem.minSize = 0;        particleSystem.maxSize = 0;        particleSystem.minLifeTime = 0.2;        particleSystem.maxLifeTime = 0.2;        particleSystem.minEmitPower = 0.5;        particleSystem.maxEmitPower = 0.5;        particleSystem.emitRate = 400;        particleSystem.blendMode = BABYLON.ParticleSystem.BLENDMODE_ONEONE;        particleSystem.minEmitBox = new BABYLON.Vector3(0, 0, 0);        particleSystem.maxEmitBox = new BABYLON.Vector3(0, 0, 0);        particleSystem.direction1 = new BABYLON.Vector3(0, 1, 0);        particleSystem.direction2 = new BABYLON.Vector3(0, 1, 0);        particleSystem.color1 = new BABYLON.Color4(0, 0, 0.5, 1);        particleSystem.color2 = new BABYLON.Color4(0, 0, 0.5, 1);        particleSystem.gravity = new BABYLON.Vector3(0, 1, 0);        particleSystem.manualEmitCount = 0;        particleSystem.emitter = new BABYLON.Vector3(0, 0, 0);        particleSystem.start();                this._particleSystem = particleSystem;            };   

Add edit speed elevation :

WORLDMONGER.ElevationControl.prototype.speed = function(speed) {     this.speed = speed; };

in the "attachControl" event "_onBeforeRender":   

        this._onBeforeRender = function () {            if (!currentPosition) return;                        pickInfo = that._ground.getScene().pick(currentPosition.x, currentPosition.y);            if (!pickInfo.hit) return;            if (pickInfo.pickedMesh != that._ground) return;            that._particleSystem.emitter = pickInfo.pickedPoint.add(new BABYLON.Vector3(-that.radius / 2, 0, -that.radius / 2));                        that._particleSystem.maxEmitBox = new BABYLON.Vector3(that.radius, that.radius, that.radius);            that._particleSystem.minSize = that.radius * 3;            that._particleSystem.maxSize = that.radius * 3;            that._particleSystem.manualEmitCount += 90 * that.radius;                                    that._elevateFaces(pickInfo, that.radius, that.speed);        };

It is a pity that this is not what I wanted to do at the beginning.

Gizmo: Yes (next week in everything comes together)

 

What becomes this project 'Babylon editor' ?

[GameMonetize]

here is it:

And a blog about it:

[Dad72]

thank you very much.

 

I succeeded to add the gizmos on my project. Thank you for this babylonEditor yet.
