t_Rendering — TFT.OpenGPU.Stack.Module

1. Rendering Intent#

The rendering layer defines the open rendering primitives that receive dimensional intent from the substrate and produce the visible scene.
It is the middle view of the module — the bridge between hidden substrate intent and visible execution work.

Its purpose is to:

• map TFT dimensional primitives into GPU-renderable structures
• provide an open, vendor-neutral rendering surface (Vulkan/WebGPU/custom)
• support remote reconstruction via TFT primitive streams
• maintain RTT coherence across substrate and execution layers
• enable Cloud PC rendering fidelity independent of vendor lock-in

2. Rendering Principles#

2.1 Middle View (Inverted Star Alignment)#

The rendering layer is the inversion boundary:

• Substrate (hidden view): dimensional intent
• Rendering (middle view): scene/viewport abstraction
• Execution (visible view): GPU work

Rendering is where dimensional primitives become:

• surfaces
• materials
• transforms
• viewports
• scene graphs

2.2 Open Rendering Model#

The rendering layer is intentionally open:

• Vulkan
• WebGPU
• custom lightweight rendering layer
• UE-style scene graph (optional)
• GPU-native reconstruction

This avoids proprietary rendering stacks and aligns with the module’s open substrate philosophy.

2.3 Bounded Drift#

Rendering reinterpretation of substrate primitives is allowed only within bounded drift:

• reinterpretation must preserve dimensional intent
• reinterpretation must remain structurally consistent
• reinterpretation must not alter RTT coherence

3. Rendering Primitive Families#

3.1 Scene Primitives#

• Render.Scene — scene container
• Render.Node — scene node
• Render.Mesh — mesh or surface representation
• Render.Light — light primitive
• Render.Camera — camera primitive

3.2 Material Primitives#

• Render.Material — material wrapper
• Render.ShaderGraph — shader graph intent
• Render.Texture — texture binding
• Render.Color — color primitive

3.3 Transform Primitives#

• Render.Transform — transform operator
• Render.Matrix — matrix representation
• Render.Space — dimensional space mapping

3.4 Viewport Primitives#

• Render.Viewport — viewport declaration
• Render.Frame — frame substrate
• Render.Pass — rendering pass

3.5 Reconstruction Primitives#

• Render.Reconstruct.Surface — reconstruct surface intent
• Render.Reconstruct.Material — reconstruct material intent
• Render.Reconstruct.Transform — reconstruct transform intent
• Render.Reconstruct.Viewport — reconstruct viewport substrate

4. Substrate → Rendering Mapping#

Rendering primitives map substrate primitives through declared coherence:

This mapping is declared, not inferred.

5. Rendering and RDP Integration#

The rendering layer defines the reconstruction path for RDP:

• substrate primitives → encoded as TFT primitive stream
• stream transported via RDPEGFX or custom virtual channel
• rendering layer reconstructs scene primitives
• execution layer resolves GPU work
• final view presented to user

Rendering provides:

• scene graph reconstruction
• material application
• transform resolution
• viewport mapping
• frame substrate generation

RDP retains:

• TLS
• CredSSP
• NLA
• reliability
• ordering
• session setup

6. Rendering and Cloud PC Tiering#

Cloud PC tiers map directly to rendering fidelity:

• Tier → reconstruction fidelity
• Tier → material complexity
• Tier → transform precision
• Tier → viewport resolution
• Tier → rendering pass count

Even minimal tiers achieve smooth rendering due to dimensional primitives.

7. Open Rendering Surface#

The rendering layer defines the open rendering surface:

• Vulkan alignment
• WebGPU compatibility
• UE-style scene graph (optional)
• GPU-native reconstruction
• vendor-neutral rendering primitives
• open shader graph semantics

This is the layer that ensures the stack remains open and AMD-friendly.

8. Canonical Rendering Summary#

The rendering layer of the TFT.OpenGPU.Stack.Module:

• defines open rendering primitives
• maps substrate intent into visible scene structures
• reconstructs dimensional primitives for remote rendering
• supports RDP integration
• enables Cloud PC tiering
• aligns with RTT (rtt=1, coherence declared, drift bounded, paradox structural)
• establishes an open rendering surface independent of NVIDIA’s closed ecosystem
