Billboards

Hi!

i want to create a plane, which is billboarded (rotating around its center)

but i just dont get it to work

is there any material / shader which does that for me?

does it even work if a plane i created with CreatePlane() ?

Does the plane have a materail attached to it? otherwise you can't see it.

You can just use a corona. I made some kind of starfield with that.

The most simple approach i used for testing was:

 

for (int i = 0; i < 1000; i++)
{
	TCorona NewCorona = CreateCorona (0);
	TVec3 Vec3Temp;
	Vec3Temp.X = 3000.0F - (float)(rand() % 6000); 
	Vec3Temp.Y = 3000.0F - (float)(rand() % 6000);
	Vec3Temp.Z = 3000.0F - (float)(rand() % 6000); 
	PositionEntity (NewCorona, Vec3Temp, 0);
	SetCoronaRadius(NewCorona, 10, 20);
	PaintEntity(NewCorona, LoadMaterial("abstract::Corona_Sun_001.mat"));
	EntityViewRange (NewCorona, 0.0F, 3000.0F, 1);
}

 

This makes a static "starfield", if you use some kind of star corona dds file.

The stars are always rotated towards the camera and the FPS drop is minimal if you son't choose to have thousands

Thanks a lot
