From 455c06ecd466424cdf1b444a7c289b322390e795 Mon Sep 17 00:00:00 2001 From: reduz Date: Wed, 20 Jul 2022 01:11:13 +0200 Subject: Implement Vector4, Vector4i, Projection Implement built-in classes Vector4, Vector4i and Projection. * Two versions of Vector4 (float and integer). * A Projection class, which is a 4x4 matrix specialized in projection types. These types have been requested for a long time, but given they were very corner case they were not added before. Because in Godot 4, reimplementing parts of the rendering engine is now possible, access to these types (heavily used by the rendering code) becomes a necessity. **Q**: Why Projection and not Matrix4? **A**: Godot does not use Matrix2, Matrix3, Matrix4x3, etc. naming convention because, within the engine, these types always have a *purpose*. As such, Godot names them: Transform2D, Transform3D or Basis. In this case, this 4x4 matrix is _always_ used as a _Projection_, hence the naming. --- modules/raycast/raycast_occlusion_cull.cpp | 6 +++--- modules/raycast/raycast_occlusion_cull.h | 6 +++--- 2 files changed, 6 insertions(+), 6 deletions(-) (limited to 'modules/raycast') diff --git a/modules/raycast/raycast_occlusion_cull.cpp b/modules/raycast/raycast_occlusion_cull.cpp index 89e75f774e..55883f9a78 100644 --- a/modules/raycast/raycast_occlusion_cull.cpp +++ b/modules/raycast/raycast_occlusion_cull.cpp @@ -78,7 +78,7 @@ void RaycastOcclusionCull::RaycastHZBuffer::resize(const Size2i &p_size) { memset(camera_ray_masks.ptr(), ~0, camera_rays_tile_count * TILE_RAYS * sizeof(uint32_t)); } -void RaycastOcclusionCull::RaycastHZBuffer::update_camera_rays(const Transform3D &p_cam_transform, const CameraMatrix &p_cam_projection, bool p_cam_orthogonal, ThreadWorkPool &p_thread_work_pool) { +void RaycastOcclusionCull::RaycastHZBuffer::update_camera_rays(const Transform3D &p_cam_transform, const Projection &p_cam_projection, bool p_cam_orthogonal, ThreadWorkPool &p_thread_work_pool) { CameraRayThreadData td; td.thread_count = p_thread_work_pool.get_thread_count(); @@ -88,7 +88,7 @@ void RaycastOcclusionCull::RaycastHZBuffer::update_camera_rays(const Transform3D td.camera_dir = -p_cam_transform.basis.get_column(2); td.camera_orthogonal = p_cam_orthogonal; - CameraMatrix inv_camera_matrix = p_cam_projection.inverse(); + Projection inv_camera_matrix = p_cam_projection.inverse(); Vector3 camera_corner_proj = Vector3(-1.0f, -1.0f, -1.0f); Vector3 camera_corner_view = inv_camera_matrix.xform(camera_corner_proj); td.pixel_corner = p_cam_transform.xform(camera_corner_view); @@ -524,7 +524,7 @@ void RaycastOcclusionCull::buffer_set_size(RID p_buffer, const Vector2i &p_size) buffers[p_buffer].resize(p_size); } -void RaycastOcclusionCull::buffer_update(RID p_buffer, const Transform3D &p_cam_transform, const CameraMatrix &p_cam_projection, bool p_cam_orthogonal, ThreadWorkPool &p_thread_pool) { +void RaycastOcclusionCull::buffer_update(RID p_buffer, const Transform3D &p_cam_transform, const Projection &p_cam_projection, bool p_cam_orthogonal, ThreadWorkPool &p_thread_pool) { if (!buffers.has(p_buffer)) { return; } diff --git a/modules/raycast/raycast_occlusion_cull.h b/modules/raycast/raycast_occlusion_cull.h index 6562c4e9c4..42433afed2 100644 --- a/modules/raycast/raycast_occlusion_cull.h +++ b/modules/raycast/raycast_occlusion_cull.h @@ -32,7 +32,7 @@ #define OCCLUSION_CULL_RAYCASTER_H #include "core/io/image.h" -#include "core/math/camera_matrix.h" +#include "core/math/projection.h" #include "core/object/object.h" #include "core/object/ref_counted.h" #include "core/templates/local_vector.h" @@ -76,7 +76,7 @@ public: virtual void clear() override; virtual void resize(const Size2i &p_size) override; void sort_rays(const Vector3 &p_camera_dir, bool p_orthogonal); - void update_camera_rays(const Transform3D &p_cam_transform, const CameraMatrix &p_cam_projection, bool p_cam_orthogonal, ThreadWorkPool &p_thread_work_pool); + void update_camera_rays(const Transform3D &p_cam_transform, const Projection &p_cam_projection, bool p_cam_orthogonal, ThreadWorkPool &p_thread_work_pool); ~RaycastHZBuffer(); }; @@ -183,7 +183,7 @@ public: virtual HZBuffer *buffer_get_ptr(RID p_buffer) override; virtual void buffer_set_scenario(RID p_buffer, RID p_scenario) override; virtual void buffer_set_size(RID p_buffer, const Vector2i &p_size) override; - virtual void buffer_update(RID p_buffer, const Transform3D &p_cam_transform, const CameraMatrix &p_cam_projection, bool p_cam_orthogonal, ThreadWorkPool &p_thread_pool) override; + virtual void buffer_update(RID p_buffer, const Transform3D &p_cam_transform, const Projection &p_cam_projection, bool p_cam_orthogonal, ThreadWorkPool &p_thread_pool) override; virtual RID buffer_get_debug_texture(RID p_buffer) override; virtual void set_build_quality(RS::ViewportOcclusionCullingBuildQuality p_quality) override; -- cgit v1.2.3
