From 8296fe5180b979b9d1f32f6375b41f0e0a8a399d Mon Sep 17 00:00:00 2001 From: skal Date: Sun, 8 Feb 2026 17:39:33 +0100 Subject: feat(gpu): Add parameter-driven ChromaAberrationEffect MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements Task #73 - Extends shader parametrization system to ChromaAberrationEffect following the FlashEffect pattern. Changes: - Added ChromaAberrationParams struct (offset_scale, angle) - Added ChromaUniforms with proper WGSL alignment (32 bytes) - Updated shader to compute offset direction from angle parameter - Extended seq_compiler to parse offset/angle parameters - Updated demo.seq with 2 parameterized instances: * Line 50: offset=0.03 angle=0.785 (45° diagonal, stronger) * Line 76: offset=0.01 angle=1.57 (90° vertical, subtle) Technical details: - Backward-compatible default constructor maintained - Migrated from raw buffer to UniformBuffer - Shader computes direction: vec2(cos(angle), sin(angle)) - Generated code creates ChromaAberrationParams initialization Testing: - All 32/32 tests pass - Demo runs without errors - Binary size: 5.6M stripped (~200-300 bytes impact) Co-Authored-By: Claude Sonnet 4.5 --- src/gpu/uniform_helper.h | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) (limited to 'src/gpu/uniform_helper.h') diff --git a/src/gpu/uniform_helper.h b/src/gpu/uniform_helper.h index afc4a4b..151153f 100644 --- a/src/gpu/uniform_helper.h +++ b/src/gpu/uniform_helper.h @@ -12,15 +12,14 @@ // UniformBuffer uniforms_; // uniforms_.init(device); // uniforms_.update(queue, my_data); -template -class UniformBuffer { +template class UniformBuffer { public: UniformBuffer() = default; // Initialize the uniform buffer with the device void init(WGPUDevice device) { - buffer_ = gpu_create_buffer(device, sizeof(T), - WGPUBufferUsage_Uniform | WGPUBufferUsage_CopyDst); + buffer_ = gpu_create_buffer( + device, sizeof(T), WGPUBufferUsage_Uniform | WGPUBufferUsage_CopyDst); } // Update the uniform buffer with new data -- cgit v1.2.3
