WebbReconstruct the world space positions of pixels from the depth texture. The Unity shader in this example reconstructs the world space positions for pixels using a depth texture and screen space UV coordinates. The shader draws a checkerboard pattern on a mesh to visualize the positions. The following illustration shows the end result: Webb14 sep. 2024 · Then you reconstruct it as: const float depth = normalDepth.w * (FarPlane - NearPlane); but this misses both the offset by NearPlane, and the negative sign to flip the Z axis (since it points out of the screen in right-handed view space, but you want to store positive values).
