Module device 

Pipeline / buffer / texture creation helpers (render-thread only).

Every creator here hands its RID straight to an Owned handle bound to the caller’s RidSink, so the resource is released by Drop alone — see gpu::owned for the drop-order contract. Nothing in this module frees a RID explicitly.

Functions

atlas_texture

RGBA8-UNORM storage texture (compute writes, material samples). Used for the Phase-4 per-chunk colour/normal detail atlases: STORAGE_BIT so the bake compute pass can write it, SAMPLING_BIT so terrain_chunk.gdshader can texelFetch it. Normals are encoded *0.5+0.5 into [0,1] to fit unorm.

attribute_texture

RGBA16F storage texture (compute writes, material samples).

compute_pipeline

Compute shader + pipeline from SPIR-V bytes produced by build.rs.

compute_pipeline_from_glsl

Compute shader + pipeline from GLSL source compiled at runtime by Godot’s own shader compiler (no slangc, nothing extra shipped). Used for the user-authored custom-surface terrain (crate::custom_surface): a compile error is logged with Godot’s message and returns None so the caller can fall back to the built-in path instead of crashing.

position_texture

RGBA32F storage texture (compute writes world positions, material samples). One texel per vertex: the surface material reads VERTEX from here because a spatial shader cannot sample the verts storage buffer the readback uses.

storage_buffer

Storage buffer pre-filled with bytes.

storage_buffer_empty

Uninitialized storage buffer of size bytes.
