emil28092005	a2000b55b5	feat: cubemap shadows with R32_SFLOAT color attachment — linear distance ... Root cause of broken shadows: depth buffer stores non-linear NDC depth, not linear distance. closestDepth * 60.0 was wrong conversion. Fix: switch from depth-only to R32_SFLOAT color attachment approach: - Shadow vertex shader outputs world position to fragment - Shadow fragment shader writes length(fragPos - lightPos) / farPlane - Main fragment shader samples cubemap, multiplies by FAR_PLANE=60 - Separate color cube (R32_SFLOAT, sampled) + depth cube (D32_SFLOAT, depth test) - Shadow pipeline: 1 color attachment (R) + depth attachment - Color clear = 1.0 (max distance), depth clear = 1.0 Tests: 227 total, all pass - ShadowMapFaceDirectionTests: 6 face directions, 90° FOV, up vectors, valid matrices, far plane consistency - ShadowShaderTests: all 6 SPIR-V shaders exist	2026-06-18 21:27:48 +03:00
emil28092005	e6e305dfa9	feat: shadow mapping — depth-only render pass from light POV + PCF ... - VulkanShadowMap.cs: 2048x2048 D32_SFLOAT image, sampler (clamp-to-border), separate shadow pipeline (depth-only, no color, depth bias enabled, CULL_NONE) - Shadow shaders: shadow.vert (lightViewProj * model * pos), shadow.frag (empty) - Main shaders updated: fragLightSpacePos output from vertex, PCF 3x3 in fragment - Push constants expanded to 160B: model(64) + lightPos(16) + lightColor(16) + lightViewProj(64) - 3 push constant ranges: Vertex(model), Fragment(light), Vertex|Fragment(lightViewProj) - Descriptor set: 2 bindings — UBO(vp) + CombinedImageSampler(shadowMap) - Shadow pass: before main pass, renders scene depth from light position - Image transitions: shadow map UNDEFINED→DEPTH→SHADER_READ_ONLY each frame - vkCmdSetDepthBias(1.25, 0, 1.75) for acne prevention - Light VP: CreateLookAt(lightPos, origin, up) * Perspective(60°, 1.0, 0.1, 60) - 0 validation errors on build	2026-06-18 20:09:32 +03:00
