From d378da77eec4d506bc01e4c08c38644d72969cc7 Mon Sep 17 00:00:00 2001 From: skal Date: Wed, 11 Feb 2026 11:34:08 +0100 Subject: refactor: Simplify effect render API and fix uniform initialization MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause: Uniform buffers created but not initialized before bind group creation, causing undefined UV coordinates in circle_mask_compute.wgsl. Changes: - Add get_common_uniforms() helper to Effect base class - Refactor render()/compute() signatures: 5 params → CommonPostProcessUniforms& - Fix uninitialized uniforms in CircleMaskEffect and CNNEffect - Update all 19 effect implementations and headers - Fix WGSL syntax error in FlashEffect (u.audio_intensity → audio_intensity) - Update test files (test_sequence.cc) Benefits: - Cleaner API: construct uniforms once per frame, reuse across effects - More maintainable: CommonPostProcessUniforms changes need no call site updates - Fixes UV coordinate bug in circle_mask_compute.wgsl All 36 tests passing (100%) handoff(Claude): Effect API refactor complete --- src/gpu/effects/distort_effect.cc | 15 ++++----------- 1 file changed, 4 insertions(+), 11 deletions(-) (limited to 'src/gpu/effects/distort_effect.cc') diff --git a/src/gpu/effects/distort_effect.cc b/src/gpu/effects/distort_effect.cc index 52a8ec7..97622b2 100644 --- a/src/gpu/effects/distort_effect.cc +++ b/src/gpu/effects/distort_effect.cc @@ -16,17 +16,10 @@ DistortEffect::DistortEffect(const GpuContext& ctx, const DistortParams& params) distort_shader_wgsl); } -void DistortEffect::render(WGPURenderPassEncoder pass, float t, float b, - float i, float a) { +void DistortEffect::render(WGPURenderPassEncoder pass, + const CommonPostProcessUniforms& uniforms) { // Populate CommonPostProcessUniforms - const CommonPostProcessUniforms common_u = { - .resolution = {(float)width_, (float)height_}, - .aspect_ratio = a, - .time = t, - .beat = b, - .audio_intensity = i, - }; - uniforms_.update(ctx_.queue, common_u); + uniforms_.update(ctx_.queue, uniforms); // Populate DistortParams const DistortParams distort_p = { @@ -35,7 +28,7 @@ void DistortEffect::render(WGPURenderPassEncoder pass, float t, float b, }; params_buffer_.update(ctx_.queue, distort_p); - PostProcessEffect::render(pass, t, b, i, a); + PostProcessEffect::render(pass, uniforms); } void DistortEffect::update_bind_group(WGPUTextureView v) { -- cgit v1.2.3
