Horizontal- & Vertical billboards

[marwie]

Hello,

prior to 0.10.6 (in version 0.7.3) we could create horizontal and vertical billboarding by modifying the mesh geometry. This doesn't work anymore. Is there a way to add this behaviour again?

Old code:

if (renderMode === ParticleSystemRenderMode.HorizontalBillboard) {
            geo = new THREE.BoxGeometry(1, 1, 0);
        }
        else if (renderMode === ParticleSystemRenderMode.VerticalBillboard) {
            geo = new THREE.BoxGeometry(1, 0, 1);
        }

Hi @marwie, I will look into this.

Thank you

@marwie , I think it's probably on your own private branch. I went back to 0.7.3. and didn't find Vertical and Horizontal Billboard. right now you can do:

            instancingGeometry: new PlaneGeometry(1, 1).rotateX((-90 / 180) * Math.PI),
            renderMode: RenderMode.Mesh,

to support horizontal billboard. I don't think we support vertical billboard that always face camera. we will it to our future feature list.

BoxGeometry has 6 faces 12 triangles, it's not efficient to do billboard rendering.

We dont have a private branch or fork. The code above is in needle engine and worked in quarks 0.7.3 as mentioned above to make particles behave correctly.

I will try what you suggest soon, thank you. And adding this feature would be great :)

@marwie added support for vertical & horizon billboard

Works like a charm, thank you
