Helper methods for computations related to the scene camera.

Public / Methods

Compute​Depth

[Pure]
public static method ComputeDepth → (1)

z in : float32

The linear Z-coordinate value, between zero and the coordinate of the far clipping plane.

returns → float32

The logarithmic depth value in the range [0..1].

Computes the logarithmic depth value.

Compute​Dot​Direction

[Pure]
public static method ComputeDotDirection → (2)

locked in : bool

Use locked camera direction?

position in : float3

The camera-centric vertex position.

returns → float4

The camera-centric vertex position (xyz) and the dot product of the vertex position and the camera direction (w).

Augments the given position with the Z-distance along the camera direction.

Compute​Position

[Pure]
public static method ComputePosition → (3)

locked in : bool

Use locked camera position?

position in : float3

The world-space vertex position.

positionExtra in : float3

The precision delta of the world-space vertex position.

returns → float3

The camera-centric vertex position.

Computes the camera-centric vertex position.

Compute​Z

[Pure]
public static method ComputeZ → (2)

z in : float32

The Z-coordinate of the transformed vertex position.

w in : float32

The W-coordinate of the transformed vertex position.

returns → float32

The logarithmic depth coordinate, to be used as replacement for z in.

Computes the logarithmic depth coordinate.

The transformation matrix that has produced z in and w in must be consistent with Configuration.NEAR_AT_ZERO.

Project​Position

2 overloads

[Pure]
public static method ProjectPosition1 → (1)

position in : float3

The camera-centric vertex position.

returns → float4

The projected vertex position.

Projects the given vertex position.

[Pure]
public static method ProjectPosition2 → (2)

position in : float3

The camera-centric vertex position.

z out : float32

Output of linear depth value (input for ComputeZ), for interpolation in pixel shader.

returns → float4

The projected vertex position.

Projects the given vertex position (logarithmic depth).

Project​Position​Shadow

[Pure]
public static method ProjectPositionShadow → (2)

position in : float3

The camera-centric vertex position.

z out : float2

Output of unclamped linear depth values (Z- and W-components), for interpolation in pixel shader.

returns → float4

The projected vertex position (clamped linear depth).

Projects the given vertex position.
