kgfx - a graphics library designed to be medium-level (sort of an RHI)

[echo anvil]

currently working on the 4th redesign on the "redesign" branch

kgfx - a graphics library designed to be high-level yet moden

kgfx - a graphics library designed to be high-level yet modern

[echo anvil]

so

resources

plan is

user does this

create resources (textures/buffers)
get required sizes and alignments
create heap (with enough allocated for resources to fit and match alignment)
emplace resources in heap at proper aligned offsets

now how should referencing them work

maybe a separate handle

[echo anvil]

KGFXTexture texture = kgfxCreateTexture(...);
KGFXBuffer buffer = kgfxCreateBuffer(...);

KGFXu64 s = kgfxGetTextureSizeRequirement(..., texture);
KGFXu64 a = kgfxGetBufferAlignmentRequirement(..., buffer);
KGFXu64 r = s % a;

KGFXu64 size = s + ((r == 0) ? r : s - r) + kgfxGetBufferSizeRequirement(..., buffer);
KGFXHeap heap = kgfxCreateHeap(..., size, KGFX_HEAP_TYPE_DEVICE, ...);
kgfxEmplaceHeapTexture(..., heap, texture, 0);
kgfxEmplaceHeapBuffer(..., heap, buffer, s + ((r == 0) ? r : s - r));

[echo anvil]

now instead

KGFXTexture texture = kgfxCreateTexture(..., resourceType, format, width, height, depth);
KGFXBuffer buffer = kgfxCreateBuffer(..., resourceType, format, size);

this is very close to vulkan

whats the goal of this lib

[echo anvil]

an abstraction from Vulkan, d3d12, and metal
sort of like an RHI

it's meant to be high level compared to Vulkan but not OpenGL level

[echo anvil]

cursed code inside the buffer creation to initialize with a pointer to buffer data

kgfx - a graphics library designed to be medium-level (sort of an RHI)

[echo anvil]

buffer copies working

along with implicit transitioning

[echo anvil]

buffer to image copying working
