Description

sealed class Tinman.Engine.Shaders.Camera

Full source code is included in the Tinman 3D SDK download.

Helper methods for computations related to the scene camera.

[Pure]
public static method Depth → (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.

[Pure]
public static method DotDirection → (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.

[Pure]
public static method Position → (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.

_2 overloads

[Pure]
public static method Project¹ → (1)

Projects the given vertex position.

[Pure]
public static method Project² → (2)

position ⁱⁿ : float3: The camera-centric vertex position.
z ^out : float32: Output of linear depth value (input for Z), for interpolation in pixel shader.
returns → float4: The projected vertex position.

Projects the given vertex position (logarithmic depth).

[Pure]
public static method ProjectShadow → (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.

[Pure]
public static method Z → (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.
