+# Lighting & Skybox Plan
+
+## Current State
+
+| Item | Current |
+|------|---------|
+| Vertex format | `float3 Position` + `float4 Color` (28 bytes, no normals) |
+| Vertex shader | [Triangle.vert.hlsl](file:///w:/Classified/Juliet/Assets/source/Triangle.vert.hlsl) — bindless buffer read, `mul(VP, mul(Model, pos))` |
+| Fragment shader | [SolidColor.frag.hlsl](file:///w:/Classified/Juliet/Assets/source/SolidColor.frag.hlsl) — passthrough `return Color` |
+| Push constants | `ViewProjection` + `Model` + `BufferIndex` + extras |
+| Texturing | None — no sampler usage, no texture reads |
+
+---
+
+## Phase 1: Add Normals to Vertex Data
+
+Lighting requires normals. This is the foundation for everything else.
+
+### Vertex Format Change
+
+```diff
+ struct Vertex
+ {
+     float Position[3];
++    float Normal[3];
+     float Color[4];
+ };
+```
+
+- **Stride**: 28 → 40 bytes
+- Update `Triangle.vert.hlsl` stride constant: `uint stride = 40;`
+- Load normal after position: `float3 normal = asfloat(buffer.Load3(offset + 12));`
+- Load color shifts to: `float4 col = asfloat(buffer.Load4(offset + 24));`
+
+### Files to modify
+
+| File | Change |
+|------|--------|
+| [VertexData.h](file:///w:/Classified/Juliet/Juliet/include/Graphics/VertexData.h) | Add `float Normal[3]` to `Vertex` |
+| [MeshRenderer.cpp](file:///w:/Classified/Juliet/Juliet/src/Graphics/MeshRenderer.cpp) | Update `AddCube()` to include per-face normals |
+| [Triangle.vert.hlsl](file:///w:/Classified/Juliet/Assets/source/Triangle.vert.hlsl) | Update stride, load normal, pass to fragment |
+
+---
+
+## Phase 2: Basic Directional Light (Diffuse)
+
+Simple single directional light with diffuse (Lambert) shading.
+
+### Approach: Push light data through RootConstants
+
+Add light direction and color to `RootConstants.hlsl` and the C++ `PushData`:
+
+```hlsl
+// RootConstants.hlsl additions
+float3   LightDirection;  // Normalized, world-space
+float    _LightPad;
+float3   LightColor;
+float    AmbientIntensity;
+```
+
+```cpp
+// PushData additions
+Vector3 LightDirection;
+float   _LightPad;
+Vector3 LightColor;
+float   AmbientIntensity;
+```
+
+### Shader Changes
+
+**Vertex shader** — transform normal to world space and pass it to fragment:
+
+```hlsl
+// Triangle.vert.hlsl output struct
+struct Output
+{
+    float4 Color    : TEXCOORD0;
+    float3 WorldNormal : TEXCOORD1;
+    float4 Position : SV_Position;
+};
+
+// In main():
+float3 worldNormal = mul((float3x3)Model, normal);
+output.WorldNormal = worldNormal;
+```
+
+> [!NOTE]
+> Using `(float3x3)Model` for normal transform is only correct for uniform-scale transforms. For non-uniform scale, you'd need the inverse-transpose. Fine for now with translation-only transforms.
+
+**Fragment shader** — apply Lambert diffuse:
+
+```hlsl
+// SolidColor.frag.hlsl → rename to Lit.frag.hlsl
+#include "RootConstants.hlsl"
+
+float4 main(float4 Color : TEXCOORD0, float3 WorldNormal : TEXCOORD1) : SV_Target0
+{
+    float3 N = normalize(WorldNormal);
+    float  NdotL = saturate(dot(N, -LightDirection));
+    float3 diffuse = Color.rgb * LightColor * NdotL;
+    float3 ambient = Color.rgb * AmbientIntensity;
+    return float4(diffuse + ambient, Color.a);
+}
+```
+
+### Files to modify
+
+| File | Change |
+|------|--------|
+| [RootConstants.hlsl](file:///w:/Classified/Juliet/Assets/source/RootConstants.hlsl) | Add light params |
+| [MeshRenderer.h](file:///w:/Classified/Juliet/Juliet/include/Graphics/MeshRenderer.h) | Add light params to `PushData` |
+| [Triangle.vert.hlsl](file:///w:/Classified/Juliet/Assets/source/Triangle.vert.hlsl) | Pass world normal to fragment |
+| [SolidColor.frag.hlsl](file:///w:/Classified/Juliet/Assets/source/SolidColor.frag.hlsl) | Lambert diffuse + ambient |
+| [DebugDisplayRenderer.cpp](file:///w:/Classified/Juliet/Juliet/src/Graphics/DebugDisplayRenderer.cpp) | Update push data struct to match new layout |
+| [main.cpp](file:///w:/Classified/Juliet/JulietApp/main.cpp) | Set `LightDirection`, `LightColor`, `AmbientIntensity` |
+
+---
+
+## Phase 3: Skybox
+
+A skybox renders a cubemap texture behind all geometry, giving the scene a background.
+
+### Approach: Fullscreen-triangle with inverse VP
+
+Render a fullscreen triangle as the very last thing (or first with depth write off), sample a cubemap using the camera view direction reconstructed from screen coordinates.
+
+### New Assets
+
+- **Skybox cubemap texture** — a `.dds` or 6 `.png` face images loaded as a `TextureCube`
+- **New shaders**: `Skybox.vert.hlsl` + `Skybox.frag.hlsl`
+
+### Shader Design
+
+**Vertex shader** — fullscreen triangle using `SV_VertexID`:
+
+```hlsl
+// Skybox.vert.hlsl
+#include "RootConstants.hlsl"
+
+struct Output
+{
+    float3 ViewDir  : TEXCOORD0;
+    float4 Position : SV_Position;
+};
+
+Output main(uint vertexID : SV_VertexID)
+{
+    Output output;
+
+    // Fullscreen triangle
+    float2 uv = float2((vertexID << 1) & 2, vertexID & 2);
+    float4 clipPos = float4(uv * 2.0 - 1.0, 1.0, 1.0);
+    clipPos.y = -clipPos.y;
+
+    output.Position = clipPos;
+
+    // Reconstruct view direction from clip space
+    // InverseViewProjection needs to be added to RootConstants
+    float4 worldPos = mul(InverseViewProjection, clipPos);
+    output.ViewDir = worldPos.xyz / worldPos.w;
+
+    return output;
+}
+```
+
+**Fragment shader** — sample cubemap:
+
+```hlsl
+// Skybox.frag.hlsl
+#include "RootConstants.hlsl"
+
+float4 main(float3 ViewDir : TEXCOORD0) : SV_Target0
+{
+    TextureCube skybox = ResourceDescriptorHeap[TextureIndex];
+    SamplerState samp = SamplerDescriptorHeap[0]; // Linear clamp
+    return skybox.Sample(samp, normalize(ViewDir));
+}
+```
+
+### Pipeline Requirements
+
+| Setting | Value |
+|---------|-------|
+| Depth write | **Off** (skybox is infinitely far) |
+| Depth test | **LessEqual** or **Off** (render behind everything) |
+| Cull mode | **None** (fullscreen triangle) |
+| Draw call | `Draw(3, 0)` — no vertex buffer needed |
+
+### New C++ Components
+
+1. **Cubemap loading** — need to create `TextureCube` from 6 face images or a `.dds` cubemap file
+2. **Skybox pipeline** — new `GraphicsPipeline` with the skybox shaders and the pipeline settings above
+3. **Sampler** — need at least one linear sampler in the sampler heap (may already exist for ImGui)
+4. **`InverseViewProjection`** — add to `RootConstants` and compute in C++ via a `MatrixInverse` function
+
+> [!IMPORTANT]
+> `MatrixInverse` needs to be implemented in `Matrix.h`. This is a non-trivial 4×4 matrix inversion (adjugate/determinant method or Gauss-Jordan).
+
+### Files to modify/create
+
+| File | Change |
+|------|--------|
+| [NEW] `Skybox.vert.hlsl` | Fullscreen triangle + view direction |
+| [NEW] `Skybox.frag.hlsl` | Cubemap sample |
+| [RootConstants.hlsl](file:///w:/Classified/Juliet/Assets/source/RootConstants.hlsl) | Add `InverseViewProjection` |
+| [Matrix.h](file:///w:/Classified/Juliet/Juliet/include/Core/Math/Matrix.h) | Add `MatrixInverse()` |
+| [MeshRenderer.h](file:///w:/Classified/Juliet/Juliet/include/Graphics/MeshRenderer.h) | Add `InverseViewProjection` to `PushData` |
+| [main.cpp](file:///w:/Classified/Juliet/JulietApp/main.cpp) | Create skybox pipeline, load cubemap, render skybox |
+
+---
+
+## Recommended Implementation Order
+
+```mermaid
+graph LR
+    A["Phase 1<br/>Add Normals"] --> B["Phase 2<br/>Directional Light"]
+    B --> C["Phase 3<br/>Skybox"]
+```
+
+1. **Phase 1** (normals) is the smallest and unblocks Phase 2
+2. **Phase 2** (lighting) gives the cubes visible 3D depth immediately
+3. **Phase 3** (skybox) is independent of lighting but benefits from having `MatrixInverse` and sampler infrastructure
+
+> [!TIP]
+> Phases 1+2 together are a single session of work (~8 files). Phase 3 is larger due to cubemap loading and new pipeline creation.
+
+---
+
+## Open Questions
+
+1. **Cubemap source** — procedural gradient skybox (no asset needed) vs actual HDR cubemap `.dds` file?
+2. **Sampler heap** — does the engine already have a linear sampler registered, or does one need to be created?
+3. **Specular** — want Blinn-Phong specular in Phase 2, or just diffuse + ambient for now?
