Create Billboard

Billboard allows simulating far objects like bushes or trees reducing the amount of geometry needed to render your scene.

Create a Billboard in Evergine Studio

You can create a billboard click button on from Entity Hierarchy panel to deploy a create menu options and click on the option "Billboard"

A billboard entity will be added to your scene

In the billboard component of your billboard entity you will find the following properties:

Property	Description
Texture	The billboard texture.
TintColor	Each pixel of the Billboard will be multiplied by such color during the drawing. By default, it is white.
Origin	Gets or sets the Billboard Origin. The origin (also known as pivot) from where the entity scales, rotates and translates. Its values are included in [0, 1] where (0, 0) indicates the top left corner. Such values are percentages where 1 means the 100% of the rectangle's width/height.
Rotation	The Billboard rotation.
BillboardType	The billboard type. The available types are Point orientation or Axial orientation.
FlipMode	Allows flipping the texture coords in Horizontal or Vertical.

Create a Billboard from code

The following code shows the list of components necessary to convert an entity into a billboard entity.

public class MyScene : Scene
{
    protected override void CreateScene()
    {                       
        var assetsService = Application.Current.Container.Resolve<AssetsService>();

        // Load default texture
        Texture treeTexture = assetsService.Load<Texture>(EvergineContent.Textures.BillboardTree_png);

        // Load default sampler
        SamplerState linearClampSampler = assetsService.Load<SamplerState>(EvergineContent.Samplers.LinearClampSampler);

        // Load a Render Layer description...
        RenderLayerDescription layer = assetsService.Load<RenderLayerDescription>(EvergineContent.RenderLayers.Alpha);

        var billboard = new Entity()
            .AddComponent(new Transform3D())
            .AddComponent(new Billboard()
            {
                Texture = treeTexture,
                Sampler = linearClampSampler,
                BillboardType = BillboardType.Axial_Orientation,
            })
            .AddComponent(new BillboardRenderer()
            {
                Layer = layer,
            });

        this.Managers.EntityManager.Add(billboard);
    }
}

The result:
