[vulkan] Create a staging buffer struct And move the barrier prefabs into a more convenient place. 2021-01-10 16:24:15 +00:00			`#ifndef __QF_Vulkan_barrier_h`
			`#define __QF_Vulkan_barrier_h`

[vulkan] Make some headers order-indepenedent In that they don't need Vulkan/qf_vid.h included first. 2022-05-04 04:55:56 +00:00			`#ifndef VK_NO_PROTOTYPES`

[vulkan] Add a couple of staging helper functions I got tired of writing the same 13 or so lines of code over and over (it actually put me off experimenting with Vulkan). Thus... QFV_PacketCopyBuffer does the work of handling barriers and a (full packet) copy from the staging buffer to a GPU buffer. QFV_PacketCopyImage does a similar job, but for images. However, it still needs a lot of work, but it does make getting a basic texture onto the GPU much less of a hassle. Both functions should make staging data much less error-prone. 2022-10-03 00:09:34 +00:00			`typedef struct qfv_imagebarrier_s {`
[vulkan] Clean up image barriers a bit Mostly, this gets the stage flags in with the barrier, but also adds a couple more barrier templates. It should make for slightly less verbose code, and one less opportunity for error (mismatched barrier/stages). 2021-04-24 03:42:29 +00:00			`VkPipelineStageFlags srcStages;`
			`VkPipelineStageFlags dstStages;`
			`VkImageMemoryBarrier barrier;`

[vulkan] Use indexed initializers for barriers This will make maintaining the arrays much easier: no worries about getting things out of sync. 2021-12-16 13:53:19 +00:00			`// image layout transitions`

[vulkan] Implement order implement transparency It's a bit flaky for particles, especially at higher frame rates, but that's due to supporting only 64 overlapping pixels. A reasonable solution is probably switching to a priority heap for the "sort" and upping the limit. 2022-11-30 18:00:47 +00:00			`qfv_LT_Undefined_to_General,`
[vulkan] Add an undefined to shader-ro barrier I guess it's kind of UB, but it's handy for images that will be conditionally written by the GPU but need to be in shader-read-only for draw calls and the validation layers can't tell that the layers won't be used. 2023-08-02 08:51:04 +00:00			`qfv_LT_Undefined_to_ShaderReadOnly,`
