Vladimír Vondruš	bf347109c9	MeshTools: make generateIndices() work with indexed MeshData. This way one no longer needs to duplicate() the original first, leading to an enlarged size of vertex data for no reason.	3 years ago
Vladimír Vondruš	d88ec88187	MeshTools: generate*Indices() overloads taking a 2D index buffer. So these can be used directly in the generateIndices() implementation that takes a MeshData.	3 years ago
Vladimír Vondruš	4a83ea67ef	MeshTools: generate*Indices() overloads taking an existing index buffer. To perform conversion of an already-indexed TriangleStrip to Triangles, for example, without having to perform an expensive deindexing using duplicate() first.	3 years ago
Vladimír Vondruš	d8b90135cc	MeshTools: rename generate*IndicesInto() output parameters for clarity.	3 years ago
Vladimír Vondruš	6afdfc55ff	MeshTools: add assertions for element count to primitiveCount() as well. To be consistent with what the generateIndices() APIs expect -- it doesn't make sense for this API to silently round down while the other would fail for the same input. In particular, the primitiveCount() may be used to calculate allocation size for an array to pass to generateIndicesInto(), and thus it should use the same rules.	3 years ago
Vladimír Vondruš	5b22b0dbb9	MeshTools: allow empty input in generate*Indices(). The restriction didn't make sense. Disallowing 1 input vertex for lines or 1/2 input vertices for triangles sure, but 0 vertices should work as the expected behavior is obvious.	3 years ago
Vladimír Vondruš	49e093674e	MeshTools: check minimal vertex count in generateIndices() too. Before it was checked only inside generate*IndicesInto() the function delegates to, which was too late as the arrays would be allocated with an insanely high size at that point.	3 years ago
Vladimír Vondruš	d51ad4213c	MeshTools: fix generateIndices() to work with attribute-less meshes. The vertex count has to be explicitly propagated to the output in that case because it can't be figured out from any attributes in this case.	3 years ago

Vladimír Vondruš	6505276d0e	MeshTools: use reference() instead of copypasting the bugs everywhere.	4 years ago
Vladimír Vondruš	ec19c25e46	Adapt to Corrade changes.	5 years ago

Vladimír Vondruš	b77eafb9de	MeshTools: add generateQuadIndices().	6 years ago
Vladimír Vondruš	96f82ad124	Trade: unify array MeshAttributeData constructors. The array size is always last, defaulting to 0. This makes it consistent with the offset-only constructor and removes two unnecessary overloads. It's a breaking change, but I don't think array attributes have many users yet -- and better to do this now than later. In any case, sorry about breaking your code.	6 years ago

Vladimír Vondruš	9742b84815	MeshTools: properly handle array attributes everywhere. Now the tests pass again.	6 years ago
Vladimír Vondruš	521a3dac0b	Trade: make creation of non-owning MeshData references easier. While `27f6cc309d` made it easier to create references to attribute-less meshes by avoiding a branch on attributeCount() (and then using a constructor with explicit vertex count), code still had to branch on isIndexed() because indices() could be called only on indexed meshes. This change allows code like Trade::MeshData reference{data.primitive(), {}, data.indexData(), Trade::MeshIndexData{data.indices()}, {}, data.vertexData(), Trade::meshAttributeDataNonOwningArray(data.attributeData()), data.vertexCount()}; which works correctly for all cases and doesn't introduce extra branches and code paths that would need to be tested. While definitely better, I might still give up at some point and introduce some Trade::MeshData::nonOwningImmutableReference() helper for this.	6 years ago
Vladimír Vondruš	65a2ced2a7	Make this compile and test cleanly with CORRADE_NO_ASSERT defined.	6 years ago
Vladimír Vondruš	a7a0acd3a4	MeshTools: add a primitiveCount() utility. I need it in magnum-player.	6 years ago
Vladimír Vondruš	b785a8ac69	MeshTools: generateIndices() operating directly on a MeshData.	6 years ago
Vladimír Vondruš	b57a9f1027	MeshTools: tools for generating index buffers out of various primitives.	6 years ago
