- 1. Optimizing Rendering of Looking Glass SDK Yusuke Kurokawa
- 2. “Rendering” is the bottleneck I want to play “LookingGlass” with my Laptop(MacBookPro2015) not “VR Ready PC”. I‘d like to optimize the rendering. Before optimizing I have to know the current rendering.
- 3. Current Rendering... • I launched “Unity FrameDebugger” and “RenderDoc” to figure out current Rendering.
- 4. Flow of the Rendering All tiles are drawn, and then render for final result. Changing View/Projection Matrix and then drawing. Repeat this step to fill the tiled texture.
- 5. The bottleneck is here The bottleneck is here! Repeating many “Camera.Render” is the bottleneck.
- 6. The idea to reduce the execute time ... If we can choose the number of tiles (ex. 3 * 4) , we can reduce the execute time.
- 7. I found the setting The setting is here. In the“Holo PlayCapture” prefab. (I knew this setting from source code).
- 8. Detail information We can choose the size of texture and the numer of tiles. The best setting is depends on Machine spec.
- 9. Mission Complete !! No!! The “Quality” became lower! There should be other things that we can do.
- 10. Understand Camera.Render Camera.Render Culling ShadowMapPassDepthTexturePass Rendering Blit to Tile repeat TileX × TileY
- 11. Understand Camera.Render Camera.Render Culling ShadowMapPassDepthTexturePass Rendering Blit to Tile repeat TileX × TileY “Culling” and “ShadowMapPass” are in the “repeat”... But the result is not changed everytime.
- 12. We want to change to this way! Camera.RenderCulling ShadowMapPass DepthTexturePass Rendering Blit to Tile repeat TileX × TileY Executing Culling and creating ShadowMap before the “Repeat”.
- 13. Changing the behavior of “Camera.Render”... Oh we have SRP(Scriptable Render Pipeline)! Yes!!! We can implements original SRP!!!
- 14. My Custom RenderPipeline Camera.RenderCulling ShadowMapPass DepthTexturePass Rendering Blit to Tile repeat TileX × TileY This step was removed. When I implemented my own RP based on LWRP... * No cascade shadow and no screen base shadow.
- 15. Camera.RenderCulling ShadowMapPass Rendering Blit To Tile repeat TileX × TileY Camera.Render Culling ShadowMapPassDepthTexturePass Rendering Blit To Tile repeat TileX × TileY SourceCode https://github.com/wotakuro/LookingGlassRenderPipeline Before After
- 16. I’m not satisfied with this.... Much more faster... Much more optimization...
- 17. Throw away “user-friendly”. Faster and faster! - Special shaders should be written for this RenderPipeline. - Throw away PostProcessing etc... - Implements more things!
- 18. Much more faster... Currently , complete to create RenderTexture and then Blit to this Texture... Why we don’t draw to this texture directly? Camera.RenderCulling ShadowMapPass Rendering Blit to Tile repeat TileX × TileY
- 19. Much more faster... To complete rendering result , there are some material changing... Some material changing are in the “Repeat”... I wanted remove “Repeat”.... Camera.RenderCulling ShadowMapPass Rendering Blit to Tile repeat TileX × TileY
- 20. Much more faster... Camera.RenderCulling ShadowMapPass Draw to texture directly with instancing! “No Repeat” should be the fastest way!!
- 21. Now I’m trying... trying at “feature/instancingdraw” branch
