Use this overload: void AddHook(const HookID id, void (*hook)(std::shared_ptr<Object> source, std::shared_ptr<Object> extra), std::shared_ptr<Object> extra = nullptr);

Apparently this requires a closed mesh: https://github.com/melax/sandbox/issues/5#issuecomment-2069836452

Fixed, shader update required.

Fixed rotation mouse tool acting wrong No longer using SPIR-V for terrain shaders, as there was some inconsistent behavior between the shaders and the compiled binaries.

Drag to select functionality should be 100% accurate now and working correctly.

Drag-to-select-area functionality is back, now plays nicely with all mouse tools. Fixed bad brush picking behavior.

Fixed vertex and face tools, which could get weird results that did not align to the current mouse position. Vertex and mouse tools now display the up/down mouse cursor when Alt key is pressed. For now, I will keep the trenchbroom-style controls for these two tools.

Changed the translation tool to use an axis gizmo, like people were asking for. Some backfaces on the gizmo model are currently missing and cannot be picked, and its appearance will improve in future updates.

Some code I used to resize a cubemap. I think the mipmaps might not be correct, but that's okay: Pasting here in case I need it again auto plug = LoadPlugin("Plugins/ISPCTexComp.dll"); auto tex = LoadTexture(GetPath(PATH_DESKTOP) + "/diffuse.dds", LOAD_MIPCHAIN); auto mipchain = tex->mipchain; std::vector<shared_ptr<Pixmap> > chain2; for (auto p : mipchain) { { p = p->Convert(TEXTURE_RGBA16); p = p->Resize(256, 256); p = p->Convert(TEXTURE_BC6H); chain2.push_back(p); } } SaveTexture(GetPath(PATH_DESKTOP) + "/thumbnail_diffuse.dds", TEXTURE_CUBE, chain2, 6); return 0;

Here is some code that uses it, but I just can't seem to get it to work right. I don't think there is an error in my code. I had to fix this file for C++17. Maybe that is causing it? I do not understand these functions: misc.h int VertMap(const std::vector<int>& collapse_map, int a, int mx) { if (mx <= 0) return 0; while (a >= mx) { a = collapse_map[a]; } return a; } std::vector<linalg::aliases::float3> vert; std::vector<tridata> tri; std::vector<int> collapse_map; std::vector<int> permutation; tridata t; for (const auto& v : mesh->vertices) { vert.push_back(linalg::aliases::float3(v.position.x, v.position.y, v.position.z)); } for (int n = 0; n < mesh->CountPrimitives(); ++n) { t.v[0] = mesh->GetPrimitiveVertex(n, 0); t.v[1] = mesh->GetPrimitiveVertex(n, 1); t.v[2] = mesh->GetPrimitiveVertex(n, 2); tri.push_back(t); } //----------------------------- // Reduce the mesh //----------------------------- ProgressiveMesh(vert, tri, collapse_map, permutation); //----------------------------- // PermuteVertices //----------------------------- // rearrange the vertex Array std::vector<float3> temp_Array; unsigned int i; assert(permutation.size() == vert.size()); for (i = 0; i < vert.size(); i++) { temp_Array.push_back(vert[i]); } for (i = 0; i < vert.size(); i++) { vert[permutation[i]] = temp_Array[i]; } // update the changes in the entries in the triangle Array for (i = 0; i < tri.size(); i++) { for (int j = 0; j < 3; j++) { tri[i].v[j] = permutation[tri[i].v[j]]; } } //----------------------------- // Build new mesh //----------------------------- model->Clear(); mesh->extra = nullptr; mesh = model->AddMesh(); std::vector<int> newvertex(vert.size()); std::fill(newvertex.begin(), newvertex.end(), -1); //Add triangles int a, b, c, p0, p1, p2; int render_num = vert.size() * 0.5; for (unsigned int i = 0; i < tri.size(); i++) { p0 = VertMap(collapse_map, tri[i].v[0], render_num); p1 = VertMap(collapse_map, tri[i].v[1], render_num); p2 = VertMap(collapse_map, tri[i].v[2], render_num); if (p0 == p1 or p1 == p2 or p2 == p0) continue; a = newvertex[p0]; if (a == -1) { a = mesh->AddVertex(vert[p0].x, vert[p0].y, vert[p0].z); newvertex[p0] = a; } b = newvertex[p1]; if (b == -1) { b = mesh->AddVertex(vert[p1].x, vert[p1].y, vert[p1].z); newvertex[p1] = b; } c = newvertex[p2]; if (c == -1) { c = mesh->AddVertex(vert[p2].x, vert[p2].y, vert[p2].z); newvertex[p2] = c; } //int a = mesh->AddVertex(vert[p0].x, vert[p0].y, vert[p0].z); //int b = mesh->AddVertex(vert[p1].x, vert[p1].y, vert[p1].z); //int c = mesh->AddVertex(vert[p2].x, vert[p2].y, vert[p2].z); mesh->AddPrimitive(a, b, c); } mesh->UpdateBounds(); model->UpdateBounds();

I believe this is fixed now.
