Graphics　rendering　on　web　browsers　serves　as　the　foundation　for　numerous　web　applications.　Compared　with　the　widely　employed　WebGL,　the　next-generation　web　graphics　API,　WebGPU,　demonstrates　an　enhanced　capacity　to　adapt　to　modern　GPU　features,　boasting　more　significant　potential.　However,　our　experiment　shows　that　the　performance　of　current　graphics　rendering　frameworks　based　on　WebGPU　lags　behind　those　built　on　WebGL.　Such　discrepancy　primarily　arises　from　an　incomplete　alignment　with　WebGPU＇s　distinctive　features.　The　individual　rendering　of　each　graphic　leads　to　redundant　communication　between　the　CPU　and　GPU.　To　enhance　the　graphics　performance　on　the　web,　we　introduce　the　FusionRender　to　harness　the　power　of　WebGPU.　To　mitigate　redundant　communication,　FusionRender　assigns　a　unique　signature　to　each　object　and　employs　these　signatures　for　grouping,　enabling　the　consolidation　of　graphics　rendering　whenever　possible.　In　simulated　experiments　involving　the　rendering　of　multiple　objects,　FusionRender　improves　the　rendering　performance　by　29.3%-122.1%　compared　with　the　existing　optimal　baseline.　In　real　cases　with　more　complex　features,　performance　improvement　ranges　from　9.4%　to　39.7%.　Additionally,　FusionRender　exhibits　robust　performance　enhancement　across　various　devices　and　browsers.　©　2024　ACM.
