This is a code example for CollisionBillboard shader.

$Shader

{

szName = CollisionBillboard

szBillboardType = YAxis

}

Parameters

szBillboardType

• Billboard type, must be one of these values:

  • Screen: Screen aligned, always remains aligned to the screen.

  • YAxis: Y Axis aligned, always remains aligned with the camera except on the Y axis.

• YAxisViewpoint: Y Axis viewpoint aligned. Similar to YAxis; however, when looking at "bias" the polygon remains slightly rotated instead of always remaining flat with respect to the camera.

fViewpointOffset

• Moves the viewpoint position during the calculation of the YAxisViewpoint Billboard matrix.

• The offset is calculated on the camera's direction, so a positive value will move it in front of the camera.

• Valid only for YAxisViewpoint type billboards.

• Default: 0.0

• Range: [-inf..inf]
