Vladimír Vondruš	baeadc9663	Math: matrix/vector rework, part 2: matrix as array of column vectors. Overall architecture is simplififed with this change and also it's not needed to use reinterpret_cast in matrix internals anymore, thus there is no need for operator() and [][] works now always as expected without any risk of GCC misoptimizations. On the other side, constructing matrix from list of elements is not possible anymore. You have to specify the elements as list of column vectors, which might be less convenient to write, but it helps to distinguish what is column and what is row: Matrix<2, int> a(1, 2, // before 3, 4); Matrix<2, int> a(Vector<2, int>(1, 2), // now Vector<2, int>(3, 4)); For some matrix specializations (i.e. Matrix3 and Matrix4) it is possible to use list-initialization instead of explicit type specification: Matrix<3, int>({1, 2, 3}, {4, 5, 6}, {7, 8, 9}); I didn't yet figure out how to properly implement the general (constexpr) constructor to also take lists, so it's a bit ugly for now. Matrix operations are now done column-wise, which should help with future SIMD implementations, documentation is also updated accordingly. I also removed forgotten remains of matrix/matrix operator*=(), which can be confusing, as the multiplication is not commutative. Why it is not present is explained in `d9c900f076`.	13 years ago

Vladimír Vondruš	f07e4743f9	Ability to specify index range in Mesh::setIndexBuffer().	13 years ago
Vladimír Vondruš	b9513d28cb	Merged index type setting to Mesh::setIndexBuffer() and added offset. Now addVertexBuffer() etc. and setIndexBuffer() are even more similar.	13 years ago
Vladimír Vondruš	ea2faa91b7	Explicit offset also in Mesh::addVertexBuffer(). The offset is present in all other functions, adding it just for consistency (although it is redundant here).	13 years ago

Vladimír Vondruš	dc5a4d83d9	Removing IndexedMesh, part 5: merged documentation, removed IndexedMesh.	13 years ago
Vladimír Vondruš	a8abbdb7d3	Removing IndexedMesh, part 4: merged draw algorithm. Still source-compatible, next step is to merge the documentation and remove IndexedMesh stub altogether.	13 years ago
Vladimír Vondruš	a2a66803be	Removing IndexedMesh, part 3: moved last remaining setter to Mesh. Now only the drawing mess needs to be merged.	13 years ago
Vladimír Vondruš	dfb9491433	Saving vertex attribute parameters only if not using VAOs. Same reasoning as in previous commit.	13 years ago
Vladimír Vondruš	b20c83f258	Removing IndexedMesh, part 2: moved all member variables to Mesh. As Mesh constructor is not exactly trivial, moved it to source, allowing to hide another function pointer variable.	13 years ago
Vladimír Vondruš	e4fc418db1	Properly specify pointers for all matrix attribute columns. Really need some tests for that.	13 years ago
Vladimír Vondruš	3f1592c23d	Inlined Mesh::setVertexCount().	13 years ago
Vladimír Vondruš	688251add9	Removing IndexedMesh, part 1: moved enums and related stuff to Mesh.	13 years ago
Vladimír Vondruš	976377f0a4	Moved code to check allowed attribute types to internal implementation. TypeTraits class is now not needed at all.	13 years ago
Vladimír Vondruš	a9d25c995f	Mesh: fixed attribute stride computation. The stride was computed always for resulting GLSL type (e.g. vec4) even if the data were of anoother type (e.g. std::uint8_t[4]). The code is exceptionally ugly now, time to wrap it with unit tests.	13 years ago
Vladimír Vondruš	fbeb7b02bc	Minor renaming in shader/mesh guts. Function size() will be used later for commputing size of the attribute, renaming the original to components().	13 years ago
Vladimír Vondruš	aef9b16c62	Don't allow removing vertex/index buffer from meshes. Would cause weird issues with state, it's better to just not allow it and follow KISS principle than trying to implementing it. Also crosslinked required function calls in documentation.	14 years ago

Vladimír Vondruš	7d04b7d511	Doc++ Basic framebuffer usage, mentioned framebuffer attachments in shader documentation.	14 years ago
Vladimír Vondruš	7e66a09461	Marking all constructors explicit, except for matrix and vector classes. It prevents unwanted implicit conversions from e.g. nullptr to Camera, Vector2 to Physics::Point etc. By making all the constructors explicit it is easier to routinely add the keyword to all new classes instead of thinking about cases when to add and when not to.	14 years ago
Vladimír Vondruš	3b37dfa6b8	Deleted constructors of classes with only static members. They shouldn't be instantiated, prevent mistakes with this.	14 years ago

Vladimír Vondruš	9ead1e9deb	Thorough documentation review and update. Now whole Magnum, Magnum::SceneGraph and Magnum::Math namespaces are fully documented -- each class has at least "getting started" documentation, larger modules are documented on separate pages.	14 years ago
Vladimír Vondruš	ae013effff	Adapted to Corrade changes. Optimalizations in Corrade::TestSuite and Corrade::Utility::Debug leaded to significant reduction of compilation time - on my machine it was ~5:38 before with building of unit tests enabled, now only ~5:00.	14 years ago

Vladimír Vondruš	8abc836ae4	Allow passing nullptr to IndexedMesh::setIndexBuffer(). Similar functionality should be in Mesh itself for unbinding vertex buffers.	14 years ago
Vladimír Vondruš	8f83485653	Forward declarations for Magnum namespace in Magnum.h header.	14 years ago
Vladimír Vondruš	a3c37cd277	Doc++, minor cleanup.	14 years ago
Vladimír Vondruš	50a0e5558e	Updated OpenGL ES support in Mesh and IndexedMesh. VAOs could be supported with extensions, thus not disabling them for ES2.	14 years ago
Vladimír Vondruš	259a9f6666	Type-checked vertex attributes with type conversion possibility. * Normalization of e.g. color components passed as unsigned byte to float values is possible. * BGRA vector component ordering is possible. * Proper type checking, allowing only GLSL-equivalent types to be used as attributes. * Reverted back to typedef'ing shader attributes, as type conversion can now be specified in constructor.	14 years ago
Vladimír Vondruš	eec4e7d099	Implementation of double vertex attributes in Mesh.	14 years ago
Vladimír Vondruš	5efa8402e5	Marking some non-implemented features as "won't be supported".	14 years ago

Vladimír Vondruš	77716dacdd	Mesh rework, part 7: using EXT_direct_state_access for vertex pointers.	14 years ago
Vladimír Vondruš	56bc8825cc	Mesh rework, part 5: tracking currently bound VAO. If the VAO is already bound, not calling glBindVertexArray() again.	14 years ago
Vladimír Vondruš	2871222b86	Mesh rework, part 3: don't specify vertex/index count in constructor. In most cases the constructor is called at a very different place than where the mesh is configured, leading to mistakes and/or confusion.	14 years ago
Vladimír Vondruš	10e64d2d27	Mesh rework, part 2: reworked internals. * VAOs are used only if the extension is supported. * Removed finalize() and other already useless stuff. * Preparation for DSA and state tracking.	14 years ago
Vladimír Vondruš	5cf2428082	Merged two mesh constructors into one.	14 years ago
Vladimír Vondruš	21acb3edc6	Mesh rework, part 1: better vertex attribute management. * Instead of "binding attributes" the user now "adds vertex buffer". It corresponds better with what OpenGL itself does. * Vertex buffers now must be managed by the user. * Shader attributes are now static const members instead of typedefs to allow more convenient addVertexBuffer() calls.	14 years ago
