# vk_resources.ludic — render3d's Vulkan resources on their own: textures uploaded the way the
|
|
# renderer uploads them and read back, a mip chain, the samplers the renderer asks for, and a
|
|
# buffer filled and grown. Run it under the validation layer on each machine.
|
|
#
|
|
# gpu_vk_res.ludic speaks OpenGL's names for formats and filters, as gpu.ludic does, and those
|
|
# names only exist where Gl.* is named - hence the one Gl.pixel_scale() below. Nothing here
|
|
# opens an OpenGL context or draws with one.
