Renderer statistics for one frame, also includes current frames per second number.

Fields

pipeline: PipelineStatistics

Shows how many pipeline state changes was made per frame.

lighting: LightingStatistics

Shows how many lights and shadow maps were rendered.

geometry: RenderPassStatistics

Shows how many draw calls was made and how many triangles were rendered.

pure_frame_time: f32

Real time consumed to render a frame. Time given in seconds.

capped_frame_time: f32

Total time renderer took to process single frame, usually includes time the renderer spent waiting until the swap of the back and front buffers (can include vsync). Time given in seconds.

frames_per_second: usize

The total number of frames been rendered in one second.

texture_cache_size: usize

The total number of textures in the textures cache.

geometry_cache_size: usize

The total number of vertex+index buffers pairs in the geometry cache.

shader_cache_size: usize

The total number of shaders in the shaders cache.

uniform_buffer_cache_size: usize

The total number of uniform buffers in the cache.

Implementations

impl Statistics

pub fn begin_frame(&mut self)

Must be called before render anything.

pub fn end_frame(&mut self)

Must be called before SwapBuffers but after all rendering is done.

pub fn finalize(&mut self)

Must be called after SwapBuffers to get capped frame time.
