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	813d82717f	Trade: no need to export this helper.	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	2059b2b164	Trade: doc++	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	c13c61e17d	Trade: hint on related APIs in mutable MeshData access.	5 years ago

Aaron Gokaslan	ca677c69fe	Fix typos	5 years ago
Vladimír Vondruš	2066d82ea4	Shaders: suffix all existing shaders with GL. To make room for Vulkan shaders. Also renaming the headers, of course everything is still aliased to the old names (and marked as deprecated).	5 years ago
Vladimír Vondruš	fb5c1b14ca	Vk: rename DynamicRasterizationState::PrimitiveToplogy to MeshPrimitive. For consistency, again.	5 years ago
Vladimír Vondruš	3d136503d8	Updated copyright year.	5 years ago
Vladimír Vondruš	fc7ebcd409	Appropriately reference MeshTools::primitiveCount(). Not from GL::Mesh, because it doesn't accept GL-specific enums.	6 years ago
Vladimír Vondruš	f8389cf271	Trade: doc++	6 years ago
Vladimír Vondruš	5222cf3478	doc: change all "latest" additions/deprecations to 2020.06.	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	f5822e9384	Trade: properly include array size in attribute stride checks.	6 years ago
Vladimír Vondruš	dca9dc492d	Trade: fix ambiguity when instantiating nullptr array MeshAttributeData.	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	2dc47839ef	Trade: bootstrap scene converter plugins.	6 years ago
Vladimír Vondruš	65a2ced2a7	Make this compile and test cleanly with CORRADE_NO_ASSERT defined.	6 years ago
Vladimír Vondruš	95c93c928a	Trade: reorganize MeshAttributeData internals for better serializability. Put the pointer that differs in size on 32 and 64bit platforms last so we have at least the prefix always stable. This also makes it possible to extend the class to store 8/16 bytes of arbitrary data in there (bounds etc.). Not doing that yet, just preparing for possible extension.	6 years ago
Vladimír Vondruš	dac646e66b	Trade: repack MeshData internals to save 8 bytes on 64-bit. Now it's a 104-byte structure, was 112 before.	6 years ago
Vladimír Vondruš	0c3a7fabae	Trade: recognize also Matrix3/Matrix4 types.	6 years ago
Vladimír Vondruš	f3a92c2afb	Shaders: rethink generic attribute allocation from scratch. This adds binormals, object IDs and instanced transformation, but has to break existing locations in order to provide new guarantees.	6 years ago
Vladimír Vondruš	159c4ece50	Trade: add a TODO.	6 years ago
Vladimír Vondruš	8a2a7e4547	Trade: implement support for object IDs in MeshData.	6 years ago
Vladimír Vondruš	5e02e0ce8d	Trade: support strided arrays in MeshData::indicesInto(). There's no point in restricting this.	6 years ago
Vladimír Vondruš	f4bca9b51e	Trade: implement support for tangents and bitangents in MeshData. Originally wanted to offload this to someone else, but then realized I need those for generic vertex attribute definitions, which I need for instancing, which I need now. So here it is, at the bottom of the dependency chain.	6 years ago
Vladimír Vondruš	d8d6a2718c	Trade: recognize matrix VertexFormats in MeshData.	6 years ago
Vladimír Vondruš	27f6cc309d	Trade: allow specifying explicit vertex count on MeshData construction. Until now, except for an attribute-less index-less mesh, the vertex count was only implicitly taken from passed attributes, but it was severely limiting: - There was no way to set vertex count for an attribute-less indexed mesh, which didn't make sense - All code that made non-owning MeshData instances referencing another MeshData had to explicitly handle the attribute-less corner case to avoid vertex count getting lost - Offset-only attributes couldn't be used to specify static layout of meshes with dynamic vertex count, causing unnecessary extra allocations especially in the Primitives library.	6 years ago
Vladimír Vondruš	8c4a2b1c6f	Trade: add getters for offset and stride in MeshAttributeData. Less code and complexity than first creating a StridedArrayView in data() and then extracting offset/stride from there.	6 years ago
Vladimír Vondruš	5a276fe328	Trade: high-level docs for the MeshData class.	6 years ago
Vladimír Vondruš	c0e3a84250	Trade: support array attributes in MeshData. The last major bit needed for meshlet support.	6 years ago
Vladimír Vondruš	a29e9dc009	Trade: handle implementation-specific vertex formats in MeshData.	6 years ago
