Squareys	f447e994d2	Trade: implement support for Weights & JointIds in MeshData. This is the first builtin array attribute, with one of the objectives being an ability to support an arbitrary count of per-vertex weights in a single contiguous attribute without the complexity of having to go through several four-component attributes. On the shader side it still needs to get cut into at most four components per attribute, but there's no reason for such limitation to get propagated here as well.

Vladimír Vondruš	3129a197dd	Trade: err, no, there's no "upper 15 bits" in a 16bit MeshAttribute. And same in case of SceneField. What a weird wording choice.	3 years ago
Vladimír Vondruš	a67effb57a	Trade: allow array attributes to have implementation-specific formats. I'm not sure why this restriction was there as nothing was preventing them from being used. The attribute is only accessible through the typeless attribute(), which gives back `Containers::StridedArrayView2D<const char>` with second dimension size being set to the full stride. And there it doesn't matter if the format is an array or not. This will be useful for joint IDs and weights, for example doing crazy things like packing the IDs into an array of 8 4-bit numbers, saving half the memory compared to the smallest builtin representation using UnsignedByte[8].	4 years ago

Vladimír Vondruš	3cb7fe5993	Trade: doc++ The MeshData and SceneData find APIs had the complexity documented, do the same for MaterialData too. Plus cross-link this API from hasAttribute() / hasField() so it's easier to find.	4 years ago

Vladimír Vondruš	cfc02599e5	Trade: drop {MeshAttribute,SceneField}::Custom. I realized those are too annoying when writing a glTF exporter which contains a lot of switches over enums. And as further shown by the diff, those were only inflicting additional pain in all switch statements, nothing else, no other added value. And everywhere else the helpers are the designated way to deal with those, so there's no point in having an explicit enum value denoting start of a "custom range". It wasn't even any convenient to have it in the enum, as the extra effort needed for casting actually made it exactly the same length as if I'd just use a separately-defined constant.	4 years ago

Vladimír Vondruš	4d5c53dbc6	Trade: add MeshData::attributeId() for inverse ID mapping. A helper for knowing e.g. which texture coordinate set is given texture coordinate attribute.	4 years ago

Vladimír Vondruš	e78655c3b1	Trade: document handling of special data layouts in MeshData.	4 years ago
Vladimír Vondruš	08a205f725	Trade: support implementation-specific index types in MeshData. This mirrors what's done already for implementation-specific vertex formats, thus: * Ability to construct the classes without tripping up when trying to check for type size in various asserts * Providing a zero-size type-erased access in indices() and mutableIndices() * Disallowing typed and convenience access	4 years ago
Vladimír Vondruš	a35a3ec271	Add an ability to store implementation-specific values in MeshIndexType. The type is now extended to 32 bits. In the GL and Vk libraries it means one can now do things like MeshIndexType type = meshIndexTypeWrap(GL_UNSIGNED_BYTE); and passing that to GL::Mesh or Vk::Mesh will cause it to use the value directly, instead of doing a mapping from a generic type. The real use case for this is however to allow custom index buffer representations in Trade::MeshData. Support for that will be hooked up in the following commit.	4 years ago
Vladimír Vondruš	2d9cedfdca	Trade: support strided index buffers in MeshData. Also not something the classic GPU vertex pipeline can handle, but useful for other scenarios. Subsequently a support for array indices will be added, allowing to directly represent for example OBJ files, where each attribute has its own index buffer.	4 years ago
Vladimír Vondruš	8dddda9c77	Trade: support zero and negative strides in mesh attribute data. This is not something the classic GPU vertex pipeline can handle (except maybe Vulkan, which can handle zero strides for instanced attributes?), but useful for other scenarios. This means existing code needs to be aware of and handle the new corner case.	4 years ago
Vladimír Vondruš	b6dd52eb62	MeshTools: add a flag to toggle layout preserving in interleave() etc. This took me quite a while to realize -- not always it's desirable to have the original layout unconditionally preserved, especially if for example filtering a MeshData to just a subset of attributes.	4 years ago

Vladimír Vondruš	491b724a86	GL: refresh Mesh and Buffer docs to be less shit. Looking at the snippets, these seem to have been written back when there was no builtin shaders yet, it seems, not to mention MeshTools::compile(), Trade::MeshData or any of the other high-level APIs. Rather overwhelming to just throw huge code snippets at the user, explaining a workflow with a custom-made mesh that's going to be drawn with a custom-made shader, which is like level 999 of using the GL library.	5 years ago
Vladimír Vondruš	efa02d46df	Trade: refresh MeshData docs slightly. It was rather discouraging to start "Basic usage" with a boring-ass long snippet. On the other hand showing just compile() first would lead people to think it's all some opaque magic, so trying to balance that a bit. Also why the hell was the compile() snippet showing the horrendous GL way of specifying attribute formats? This is not great either but at least not redundant.	5 years ago

Vladimír Vondruš	25320af545	Trade: pass strided views by const&. Those have 3 pointers at least, my limit for passing by value is trivial copyability and two pointers. I hope that reflects the actual HW at least vaguely, heh.	5 years ago

Vladimír Vondruš	206c4d7a9e	Trade: no need to type that much.	5 years ago
Vladimír Vondruš	26a0bf94ff	Trade: improve MeshData type mismatch assertions. We do know what type the user requested, so why not print it as well. And for the array access the message was especially lazy.	5 years ago
Vladimír Vondruš	c24a762e15	Trade: not sure what's up with this silly temporary. Some places have it, some don't. It's shorter without.	5 years ago
Vladimír Vondruš	2b8d9c7e74	Trade: internal API was named in an outdated way. Long ago, during one of the few initial MeshData iterations. there was no VertexFormat, but rather Trade::MeshAttributeType. I managed to get rid of it mostly, except this place.	5 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
