From b8d4a815453acac752c6fb3c56d047e39a76fd05 Mon Sep 17 00:00:00 2001 From: skal Date: Sat, 14 Feb 2026 19:05:34 +0100 Subject: feat(gpu): add SDF camera infrastructure and effect base class Add unified camera system for SDF raymarching effects: - CameraParams struct (80 bytes): inv_view matrix + FOV/near/far/aspect - SDFEffect base class: manages camera uniform, provides update_camera() helpers - camera_common.wgsl: getCameraRay(), position/forward/up/right extractors - SDFTestEffect: working example with orbiting camera + animated sphere Refactor effect headers: - Extract class definitions from demo_effects.h to individual .h files - Update includes in .cc files to use specific headers - Cleaner compilation dependencies, faster incremental builds Documentation: - Add SDF_EFFECT_GUIDE.md with complete workflow - Update ARCHITECTURE.md, UNIFORM_BUFFER_GUIDELINES.md - Update EFFECT_WORKFLOW.md, CONTRIBUTING.md Tests: 34/34 passing, SDFTestEffect validated Co-Authored-By: Claude Sonnet 4.5 --- src/effects/particles_effect.h | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 src/effects/particles_effect.h (limited to 'src/effects/particles_effect.h') diff --git a/src/effects/particles_effect.h b/src/effects/particles_effect.h new file mode 100644 index 0000000..6d46ea2 --- /dev/null +++ b/src/effects/particles_effect.h @@ -0,0 +1,21 @@ +// This file is part of the 64k demo project. +// It declares the ParticlesEffect. + +#pragma once + +#include "gpu/effect.h" +#include "effects/particle_defs.h" + +class ParticlesEffect : public Effect { + public: + ParticlesEffect(const GpuContext& ctx); + void compute(WGPUCommandEncoder encoder, + const CommonPostProcessUniforms& uniforms) override; + void render(WGPURenderPassEncoder pass, + const CommonPostProcessUniforms& uniforms) override; + + private: + ComputePass compute_pass_; + RenderPass render_pass_; + GpuBuffer particles_buffer_; +}; -- cgit v1.2.3
