From 83210f2da18e366729d392f2d4ae346245d52a97 Mon Sep 17 00:00:00 2001 From: MichaelFisher1997 Date: Tue, 23 Dec 2025 23:56:49 +0000 Subject: [PATCH 1/3] Refactor: Decompose App and Fix Vulkan Parity/SOLID issues This PR addresses remaining SOLID and parity issues: - **App Decomposition**: - Extracted `RenderSystem` to `src/game/render_system.zig` (handles RHI, resources). - Extracted `WindowManager` to `src/engine/core/window.zig` (handles SDL/GL context). - `App` now delegates to these subsystems. - **Vulkan/OpenGL Parity**: - Extracted Cascaded Shadow Map (CSM) math to `src/engine/graphics/csm.zig`. - Clarified that Vulkan handles shadow resources internally in RHI, while OpenGL uses `ShadowMap` struct. Both use common CSM math. - **SOLID/Clean Code**: - Introduced `MenuContext` in `menus.zig` to reduce parameter bloat (Interface Segregation). - Fixed `pending_new_world_seed` logic to prevent infinite retry loops on world creation failure. - **Fixes**: - Fixed build errors related to missing file tracking. --- src/engine/core/window.zig | 65 +++++++ src/engine/graphics/csm.zig | 110 +++++++++++ src/engine/graphics/shadows.zig | 109 +---------- src/game/app.zig | 323 ++++++++++---------------------- src/game/menus.zig | 119 ++++++------ src/game/render_system.zig | 112 +++++++++++ 6 files changed, 459 insertions(+), 379 deletions(-) create mode 100644 src/engine/core/window.zig create mode 100644 src/engine/graphics/csm.zig create mode 100644 src/game/render_system.zig diff --git a/src/engine/core/window.zig b/src/engine/core/window.zig new file mode 100644 index 00000000..50ffb7fb --- /dev/null +++ b/src/engine/core/window.zig @@ -0,0 +1,65 @@ +const std = @import("std"); +const c = @import("../../c.zig").c; +const log = @import("log.zig"); + +pub const WindowManager = struct { + window: *c.SDL_Window, + gl_context: ?c.SDL_GLContext, + is_vulkan: bool, + + pub fn init(allocator: std.mem.Allocator, use_vulkan: bool) !WindowManager { + _ = allocator; + if (c.SDL_Init(c.SDL_INIT_VIDEO) == false) { + std.debug.print("SDL Init Failed: {s}\n", .{c.SDL_GetError()}); + return error.SDLInitializationFailed; + } + + if (!use_vulkan) { + _ = c.SDL_GL_SetAttribute(c.SDL_GL_CONTEXT_MAJOR_VERSION, 3); + _ = c.SDL_GL_SetAttribute(c.SDL_GL_CONTEXT_MINOR_VERSION, 3); + _ = c.SDL_GL_SetAttribute(c.SDL_GL_CONTEXT_PROFILE_MASK, c.SDL_GL_CONTEXT_PROFILE_CORE); + _ = c.SDL_GL_SetAttribute(c.SDL_GL_DEPTH_SIZE, 24); + } + + var window_flags: u32 = c.SDL_WINDOW_RESIZABLE; + if (use_vulkan) { + window_flags |= c.SDL_WINDOW_VULKAN; + } else { + window_flags |= c.SDL_WINDOW_OPENGL; + } + + const window = c.SDL_CreateWindow( + "Zig Voxel Engine", + 1280, + 720, + @intCast(window_flags), + ); + if (window == null) { + log.log.err("Window Creation Failed: {s}", .{c.SDL_GetError()}); + return error.WindowCreationFailed; + } + log.log.info("Window created successfully", .{}); + + var gl_context: ?c.SDL_GLContext = null; + if (!use_vulkan) { + gl_context = c.SDL_GL_CreateContext(window); + if (gl_context == null) return error.GLContextCreationFailed; + _ = c.SDL_GL_MakeCurrent(window, gl_context.?); + c.glewExperimental = c.GL_TRUE; + } + + return WindowManager{ + .window = window.?, + .gl_context = gl_context, + .is_vulkan = use_vulkan, + }; + } + + pub fn deinit(self: *WindowManager) void { + if (self.gl_context) |ctx| { + _ = c.SDL_GL_DestroyContext(ctx); + } + c.SDL_DestroyWindow(self.window); + c.SDL_Quit(); + } +}; diff --git a/src/engine/graphics/csm.zig b/src/engine/graphics/csm.zig new file mode 100644 index 00000000..f820226a --- /dev/null +++ b/src/engine/graphics/csm.zig @@ -0,0 +1,110 @@ +const std = @import("std"); +const Mat4 = @import("../math/mat4.zig").Mat4; +const Vec3 = @import("../math/vec3.zig").Vec3; +const rhi = @import("rhi.zig"); + +pub const CASCADE_COUNT = rhi.SHADOW_CASCADE_COUNT; + +pub const ShadowCascades = struct { + light_space_matrices: [CASCADE_COUNT]Mat4, + cascade_splits: [CASCADE_COUNT]f32, + texel_sizes: [CASCADE_COUNT]f32, +}; + +pub fn computeCascades(resolution: u32, camera_fov: f32, aspect: f32, near: f32, far: f32, sun_dir: Vec3, cam_view: Mat4, z_range_01: bool) ShadowCascades { + const lambda = 0.8; + const shadow_dist = far; + + var cascades: ShadowCascades = .{ + .light_space_matrices = undefined, + .cascade_splits = undefined, + .texel_sizes = undefined, + }; + + // Calculate split distances (linear/log blend) + for (0..CASCADE_COUNT) |i| { + const p = @as(f32, @floatFromInt(i + 1)) / @as(f32, @floatFromInt(CASCADE_COUNT)); + const log_split = near * std.math.pow(f32, shadow_dist / near, p); + const lin_split = near + (shadow_dist - near) * p; + cascades.cascade_splits[i] = std.math.lerp(lin_split, log_split, lambda); + } + + // Calculate matrices for each cascade + var last_split = near; + for (0..CASCADE_COUNT) |i| { + const split = cascades.cascade_splits[i]; + + // 1.
