* rewrote entirely the triangle clipping algorithmvimene2026-01-151-0/+16
| | | | | | | | | | | | | | | | | | | 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
* added textures for the hardware renderervimene2026-01-131-0/+24
- removed "using" directive in .hpp - reverse order of arguments for quaternion rotation, i.e. q.rot(v) instead of v.rot(q), where q is a quaterinon and v a vector - pass the inverse of the view matrix to render_and_present_frame, to allow light calculation in shaders (we used to just pass the matrix of the quaternion of the transformation, i.e. discard scaling and translations) - added another mesh and texture (viking_room) for testing purposes - added transparent background option - added Quaternion::look_towards(), which is the equivalent of Matrix4::look_at() but only for rotations - various improvement to .obj parsing - load texture coordinates from .obj file - merged duplicate vertices in Mesh::linearize_indices()
