Previously every input was fetched as a matrix. Now, every input is fetched as a vector, with matrices taking up multiple vectors. This saves a lot of copying and a lot of space in the cache.
Furthermore, integer state-based inputs can be defined (for future use)
Naming still needs to be revised, since it's called the "mat part cache" etc.
This does not remove support for older macOS versions, they can still be targeted by newer SDKs (10.9 can still be targeted by the macOS 12 SDK)
I would like to require macOS 11 SDK, but we still need 10.13 for FMOD
- Allows the compiler to devirtualize the get_hash_impl call, in theory
- Reduces the overhead of checking the configuration variables every time in return_new
- Avoids recalculating the hash on calling get_unique
Multiview textures are now handled as a single texture context instead of as one texture context per view. This should be marginally more efficient, but more importantly, it paves the way for implementing multiview textures as subviews of an array texture down the line, which paves the way for hardware-accelerated stereo rendering (where the left and right views get rendered simultaneously to different layers of an array texture).
The difference between a multiview texture done this way and an array texture is that the views of a multiview texture will still be treated as individual textures from the shader's point of view, only the views will be sharing the same storage on the GPU. This can be done by using a feature offered by graphics APIs that is (serendipitously) also called "texture views", where it's possible to create multiple texture objects that point to layer ranges of a bigger array texture.
That part has not yet been done as doing this in OpenGL will be a little tricky due to texture views being an optional feature (so both paths would need to be implemented), but texture views are native in Vulkan (and D3D10+ for that matter), so doing this now allows me to implement multiview textures natively on the Vulkan end right from the start, and OpenGL can follow later if desired.
Furthermore, this commit includes:
- OpenGL: Overhaul texture creation and binding
- OpenGL: Change how reloading a texture with mipmaps works
- OpenGL: Use DSA in a couple of places
- OpenGL ES: Add support for buffer textures
- OpenGL: Remove support for bindless textures for now; this was never implemented in a very useful way, not used to my knowledge, and it is better to re-implement it later after the new shader pipeline lands
- DirectX9: All views of a texture are uploaded at the same time
- TinyDisplay: Support multiview textures natively (consecutive storage in memory)
- General: Per-page texture update tracking is working properly now for multiview textures
