From 175c71637b6bea6dcdd0faf3d614339983809bb1 Mon Sep 17 00:00:00 2001 From: vimene Date: Thu, 15 Jan 2026 05:15:59 +0100 Subject: rewrote entirely the triangle clipping algorithm MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is still a lot of work needed to refactor it properly. - use the Sutherland–Hodgman algorithm, with some minor changes - made clipping more general, allowing clipping of any coordinate, before and after division by w - compute the z coordinate only at the fragment stage instead of each time clipping creates / moves a vertex, in addition to the fragment stage - added VectorCoords to choose at compile-time different coordinates based on a template argument - added transpose struct to allow shuffling of vectors coordinates - added math::utils::lerp which interpolate linearly a float - added Vector{2,3,4}::map() which maps a vector from one range to another - added template parameter to DerivedVertex (and therefore TriangleDerived) to allow choosing which dimension to use --- src/Makefile.am | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/Makefile.am') diff --git a/src/Makefile.am b/src/Makefile.am index e8f98a1..f7741a6 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -22,7 +22,8 @@ engine_SOURCES = \ o3d/vertex.hpp \ o3d/deriv_vertex.hpp \ o3d/tri.hpp \ - o3d/tri_deriv.hpp o3d/tri_deriv.cpp \ + o3d/tri_deriv.hpp \ + o3d/polygon.hpp \ o3d/camera.hpp \ o3d/scene.hpp \ ctrl/keyboard.hpp \ -- cgit v1.2.3
