Methods

getDepth()​

Returns the depth unnormalized.

Returns: Depth

Return Type: float

getLinearDepth()​

Linearize the depth.

Returns:

float depth = getDepth();
return (2.0 * nearPlane * farPlane) / (farPlane + nearPlane - (depth * 2.0f - 1.0f) * (farPlane - nearPlane));

Return Type: float

getLogisticDepth(float steepness, float offset)​

Returns:

float depth = getLinearDepth();
return (1 / (1 + exp(-steepness * (depth - offset))));

Return Type: float

getLogisticDepth()​

Returns: getLogisticDepth(0.5f, 5.0f) Return Type: float

screenspace()​

Returns the UV coordinates of the screen. E.g. the top left corner is (0, 1). OpenGL uses the bottom left corner as (0, 0).

Returns: Screenspace Coordinate

Return Type: vec2
