RenderStats Derived Type

type, public :: RenderStats

A window's frame rate and frame times (see the module documentation). Times are in milliseconds; the rate and frame time are averaged over about half a second, the rest are the last frame's.


Components

Type Visibility Attributes Name Initial
real(kind=wp), public :: acquire_ms = 0.0_wp

waiting for the next image to draw into
real(kind=wp), public :: fps = 0.0_wp

frames per second
real(kind=wp), public :: frame_ms = 0.0_wp

the time between frames
integer(kind=int64), public :: frames = 0_int64

frames drawn
real(kind=wp), public :: gpu_memory_budget = -1.0_wp

device memory available to the program (bytes; -1: unknown)
real(kind=wp), public :: gpu_memory_used = -1.0_wp

device memory in use (bytes; -1: unknown)
real(kind=wp), public :: gpu_ms = -1.0_wp

the GPU's time for a frame (-1: not measured)
integer, public :: height = 0

the image's size (framebuffer pixels)
real(kind=wp), public :: present_ms = 0.0_wp

presenting the image
real(kind=wp), public :: program_ms = 0.0_wp

the program's part of frame(): the scene's update, the handler
real(kind=wp), public :: record_ms = 0.0_wp

recording and submitting the GPU's commands
integer, public :: width = 0

the image's size (framebuffer pixels)
